体验 iMac M4 后,我发现了苹果的小心思和乔布斯的影子

By: 周奕旨
8 November 2024 at 12:00

2001 年,《老友记》第七季正在美国播出,斩获了约 2000 万平均收视人数,位列当年全美电视节目收视率的前五名。

这部从上世纪走来的经典美剧,虽然热度有些下降,但漫长的播出生命线带来了一些额外的彩蛋——剧中的产品伴随时代更迭而变迁。无论是 Nokia 手机、PlayStation 还是 Windows 系统,都有着浓烈的时代属性,寻找这些代表了一个时代的「标志物」,一度是观众津津乐道的话题。

而这一季,有个新家伙登场。

独特的半透明外壳、以浓厚的红色为主色调、屏幕边缘包裹着透明的塑料材质,以及透过外壳可以隐约看到内部的构造,放在精心设计的片场中也能第一时间抓住人的眼球。

iMac G3,这是乔布斯回归苹果后发布的首批重要作品之一。

在发布会上,乔布斯对这台技术与艺术完美结合的设备定位极其清晰:

iMac 让电脑使用变得更简单。

那是千禧年前后,互联网还是个新鲜玩意,电脑则没那么友好,设计呆板无趣、界面晦涩复杂,没有吸引力的同时学习成本也相当地高。

苹果想让 iMac 成为人们探索这个未知世界的门户,所以它技术理念先进、它使用直观易懂、它设计优雅好看,苹果甚至专门推出了一条宣传片,就为了表明 iMac 简单又有趣,连小孩子都能轻松使用。

最终目的很简单——要让每个看到它的人都跃跃欲试。

▲ iMac G3 活跃在各大影视作品中

不负众望,以这个角度切入市场的 iMac G3 大获成功,被视为苹果复兴的标志。

二十六年后,iMac M4 发布。

门面担当,性能不弱

第一眼看过去,iMac M4 最显眼的就是同样多的配色,甚至连官网的宣传标题都将彩色元素置入其中。

iMac M4 的整体配色遵循了 iMac M3 的方案:搭配相同颜色的不同饱和度,形成 iMac 的色彩美学。

高饱和度的颜色覆盖了 iMac 的整个背部面板,使其在任何角度下都能呈现出浓郁的视觉冲击力,清淡的同色系 logo 与背面的浓烈形成对比,以便在任何环境中,人们都可以一眼看见这个协调又亮眼的家伙。

清淡的颜色还填补了剩下的细节:正面底部面板与支架都选择用较低饱和度的同色系颜色示人,营造出柔和的视觉效果,让用户在使用屏幕时不易分散注意力,这倒是与苹果一贯的注意力理论相匹配。

清淡的颜色与 iMac M3 一样,保留在更换了 USB-C 接口的妙控键盘与妙控鼠标上,虽然键鼠与 iMac 不是一个整体,但依然能在复杂的环境中轻松辨认它们的配套身份。

值得一提的是,这一代的电源线也拥有了与 iMac 本体匹配的清淡颜色,而不是标配白色了。

与配色相符合的就是它的产品定位——看到这样颜色鲜艳讨喜,设计简约的 iMac,你只会想做些愉快轻松的事情,而不会想把它带到枯燥又烦闷的专业环境中。

就像全球著名设计咨询公司 IDEO 的首席执行官兼总裁蒂姆·布朗说的:

性能决定了你的产品能做什么,而设计决定了用户如何去做。

在这一代 iMac 上,最大的变化是它的大脑——M4 芯片登场。

爱范儿拿到手的是一台顶配 iMac,搭载满血 M4 芯片,32GB 内存与 2T 固态硬盘,我们先按照惯例,对它进行了一次跑分。

在 GeekBench 6 中,iMac M4 获得了单核 3699 分、多核 14833 分的成绩,作为对比,上一代 iMac M3 的单核成绩为 3138 分,多核 11912 分,获得了约百分之二十的性能提升。

今年的 WWDC,苹果宣布了 Apple Intelligence 的登场,AI 正式成为苹果产品必须具备的功能,AI 性能成为躲不开的话题。

同样是 GeekBench,iMac M4 在 AI 测试中通过 CPU 获得了单精度 4687 分、量化分数 6268 的成绩,作为对比,iMac M3 的得分为 4103 和 5615。

单精度分数代表 iMac M4 在高精度、细致计算任务(如复杂图像识别)中的能力,而量化分数则展示了它在快速、省电任务(如实时语音助手)中的效率。

不过,我们始终认为纸面参数仅供参考,只有当这些参数化作这台 iMac 的实际体验时,才赋予其真正的意义。

作为一位文字工作者,与一名摄影师,正好模拟日常大部分的使用场景,试试这台设计与性能并驾齐驱的 iMac M4。

写作需要大量的知识储备,特别是在自己不够熟悉的领域,常常需要依赖浏览器查询资料,让我能「博古通今」。

由于资料散落在互联网的各个角落,我常常需要同时打开许多网页进行翻阅。然而,许多网页包含复杂的脚本、动画或后台任务,一旦开启,CPU、GPU 和 RAM 需要并行处理各种任务,成为电脑性能的隐形杀手。

此时,iMac 能支持我同时浏览多少个网页,很关键。

测试中,我打开了 50 个网页,覆盖视频、小游戏、新闻、带动效的官网等类别,在网页全都加载完成后,我快速切换每个网页,并使用其中的动效和小游戏,iMac M4 依旧丝滑,没有任何卡顿出现。

虽然大家更为熟知的是透明大背头 iMac G3 与台灯电脑 iMac G4,但 iMac G5 才是至关重要的一代。

2004 年,一根支架撑起的「白色相框」,为未来的 iMac 设计奠定了基础。

20 年后,同样是一根支架撑起了 iMac M4,以及正面分辨率 4480 x 2520 的 24 英寸 4.5K 视网膜显示屏。

不过,一台显示屏可不够。

在我日常使用中,稿件、网页、图片处理与微信等交流工具常常同时存在,来回切换十分分散注意力,多台显示屏成为了刚需。

经过测试,这台搭载满血 M4 芯片的 iMac 支持同时连接两台分辨率为 6K(60Hz)的外接显示器,并且同时运行 Safari 浏览器、飞书、微信、剪映等日常生活工作需要的应用时没有出现明显卡顿。

一台 iMac 再加两台外置显示屏,每个任务终于都可以优雅地排列在屏幕上,不用从一堆软件的堆叠中找自己需要的界面了。

互联网的发展史,其实也是数码照片的传播史,图片随着网络一起,成为人们最基础的信息媒介之一。

摄影是我的爱好,也是我工作的一部分,在此之前,我从不会使用公司的 MacBook Air 做图片工作——因为太卡。

这不可避免地占用了我不少的休息时间。

▲ MacBook Air M1

在 M4 的加持下,新 iMac 能否承担一定的图片处理任务,这至关重要。

为了测试 iMac M4 的图片处理功能,我准备了 7 张由富士中画幅相机 GFX 100S 拍摄的图片,通过 iMac 背部的四个雷雳 4 接口传输到 Photoshop 中,使用 Photomerge 功能进行全景接片。

这七张照片每张 1 亿像素,接片后去掉重叠部分,再进行矫正,像素量达到了 4.7 亿,工程文件大小为 10.7GB。

在合成之后,我打算对这张全景照片进行调色,试试它处理静态图片的极限在哪里。

要知道,在如此庞大的像素压力下,实时处理图片是个极具挑战性的任务,性能不够的电脑往往不能实时预览调色效果,要等操作结束一两秒后才能看到调整效果。

别小看这一两秒,这一点卡顿就足以让用户拿起手机,转移本来专注的注意力。

在 iMac M4 上,我对这张全景接片先后进行了曝光调整、曲线调整、HSL 调整,并使用了三个蒙版工具,对照片做精细化调整。

在二十分钟的后期过程中,无论是对图片进行接片、畸变矫正,还是后续的曝光、颜色等基本参数进行调整,或是用蒙版精细处理局部细节,iMac 都没有掉链子。

看来,静态影像还难不倒它。

在静态影像测试时,我想到一个梗:

剪辑已经成为一个人必备的基础技能。

这句玩笑话,我听到不止一次了。

虽然有夸张的意思,但随着流媒体平台与短视频平台的兴起,视频成为信息流通的重要工具,无论是消遣娱乐,还是学习工作,都离不开这种动态媒介。

剪辑视频的能力,的确愈发重要。

普通的剪辑肯定不在话下,但生活中难免遇到偶尔超标的需求,比如调色,iMac M4 能胜任吗?

在这次测试中,我将单条 4K 60 帧,Apple ProRess 422 Proxy 规格的 Log 视频放进达芬奇,进行了一系列调整,包括:Lut 还原、白平衡调整、曝光调整、添加胶片光晕、添加胶片颗粒、降噪与锐化等一系列操作。

这对于 iMac 而言是一个不小的挑战。

在前面的还原与调色效果中,我可以在预览界面实时查看渲染过的视频,当加入胶片光晕与颗粒效果后,预览帧率下降到每秒 15 帧左右,此时还能勉强对画面进行实时的动态预览。

等降噪效果登场,iMac 才彻底吃力起来——预览界面的帧率下降到每秒 3 帧左右,几乎不可用于动态预览,只能在设置好降噪参数后先关闭节点,等输出前再打开。

这条测试视频总时长为 20 秒,共 1200 帧,输出为 4K 60 帧 H.264 视频所用时间为:

  • 带降噪与锐化效果:11 分 59 秒
  • 不带降噪与锐化效果:1 分 42 秒

从实时预览的帧率与输出速度来看,此时,iMac 几乎已经触及了自己的性能边界。

我通常只用达芬奇做粗剪与调色,等到输出以后再放到 Final Cut Pro X 中做剪辑(更偷懒的话就用剪映),这很容易让输出的片段四处散乱,得益于 iMac M4 上双双突破 3000MB/s 的读写速度,我可以在非常短的时间里完成这些零碎片段的整理工作。

从这一系列测试来看,iMac 在 M4 的加持下,完全可以轻松处理繁琐的基础任务,偶尔的「出格」需求也不在话下,虽然差点没扛住比较基础的降噪处理,但表现足以让我满意。

毕竟,对于一台更偏向于日常工作娱乐使用的电脑,快慢只是时间问题,跨过「能做」这个门槛,才是最重要的。

褪去束缚,回归本质

我们以十年为一期,纵观 iMac 的发展,背后其实隐藏着很有意思的变化。

1998 年,第一台 iMac G3 诞生。

凭借设计的优越与使用的简单,让 iMac 成为大众喜欢用、乐于用的电脑,由此成为了苹果的常青树之一。

十年过去,随着用户需求逐渐开始细分,专业软件如雨后春笋进入个人电脑。

2009 年,iMac 27 英寸与 21.5 英寸推出。

两种尺寸的屏幕、更强的 intel core i5 和 core i7 处理器、更多的 RAM,都是为用户日益多样化的使用需求准备的配置。

爱范儿的办公室里就还有一台搭载 intel 处理器的 iMac,它没有先进的 M 系列芯片,也没有多彩的颜色设计,但得益于当时苹果提供了足够多的定制选择,让它依旧很强大——在同时期的 MacBook Pro 已经相当吃力的今天,这台老 iMac 依旧可以快速响应我的需求。

▲ 搭载 intel 芯片的 iMac

又一个周期过去,随着科技进一步进展,人们对电脑的专业需求已不再浅尝即止,不同的用户,使用需求也愈发细分。

隔行如隔山,不同的行业之间的需求可能大相径庭,由于 iMac 本身一体机的特性,苹果官方提供的配置已经不足以满足所有用户五花八门的个性化需求了。

这才有了现在的 Mac 现状——Mac mini 凭借高度拓展性快速崛起,而 iMac 定位逐渐向基础使用收拢。

专业需求的转移,让 iMac 的「高配」之路戛然而止,但这并不是一件坏事,各司其职,才能为用户提供更精准的选择。

褪去了「束缚」的 iMac,比历史上任何时期都更接近诞生时的定位——凭借设计与性能的平衡,让人们乐于在日常生活中使用它。

就像 2021 年,颜色再次回归 iMac 时,库克说的那样:

iMac 是让人们感到快乐、充满灵感的设备。

这与 iMac 诞生时,乔布斯的愿景一脉相承。

又何尝不是一种历久弥新呢?

让我有个美满旅程

苹果发布 M4 MacBook Pro!全系 16G 内存起步,史上续航最长的 Mac

By: 周奕旨
31 October 2024 at 00:15

10 月初,全新的 MacBook Pro 在尚未公开前,直接被几位博主提前开箱上手,堪称苹果自 iPhone 4 以来最严重的产品泄露事件。

原本以为苹果会把发布会提前举办,接住这泼天的流量。结果,苹果跟赌气似的选择跳过发布会,还一天发一件,终于在 iMac 与 Mac mini 之后,全新 MacBook Pro 携 M4 全系列芯片登场。

还是熟悉的配方,这代 MacBook Pro 在外观上并没有太大变化,我们直接将目光先聚焦在今天的重点上——M4 系列芯片。

与 iMac 不同,MacBook Pro 上使用的 M4 芯片均为满血状态,配备 10 核 CPU 与 10 核 GPU,与昨天发布的 Mac mini 对齐。

搭载 M4 标准版芯片的 MacBook Pro 在编辑照片等任务上比配备 M1 的 13 英寸 MacBook Pro 快 1.8 倍,在 Blender 中执行渲染任务时,速度可达 3.4 倍。

搭载 M4 标准版的 MacBook Pro 另一个变化,就是同样起步就配备 16GB 内存,最高支持 32GB。

面对与日俱增的 AI 需求,电脑对内存的需求也在不断攀升。全力押注 AI 的苹果也到了不得不违背「祖宗之法」的时候了。

此前,搭载 M3 芯片的 MacBook Pro 在闭合的情况下,支持一台分辨率最高达 6K (60Hz) 的外接显示器,以及另一台分辨率最高达 5K (60Hz) 的外接显示器。

现在好了, M4 MacBook Pro 开盖也能连两台显示器。

昨天出现在 Mac mini 上的 M4 Pro 继续登场,最多集成 14 核 CPU 与 20 核 GPU 以及 16 核 NPU,M4 Pro 性能与配备 M1 Pro 的 16 英寸 MacBook Pro 相比,在 Mason Redshift 中渲染场景的性能高达 3 倍。

同时,M4 Pro 对应的起步内存与 M4 芯片也拉开了差距,升级到 24GB,最高支持 48G 内存。

为了 AI,苹果还想了别的办法——搭载了 M4 Pro 的 MacBook Pro 的内存带宽比上一代大幅增加了 75%——这是任何 AI PC 使用的芯片的两倍。

除了前两天已经发布的 M4 标准版与 M4 Pro,最大杯 M4 Max 也终于在今天亮相。

按照惯例,M4 Max 与 M4 Pro 一样分为高低两个配置,低配 14 核 CPU、32 核 GPU、16 核 NPU;高配 16 核 CPU、40 核 GPU 以及 16 核 NPU。

M4 Max 芯片版本的 MacBook Pro 内存从 36GB 起步,最高支持选配 128GB。

M4 Max 的性能也稳步提升,据苹果宣称,M4 Max 在 Maxon Redshift 场景渲染中的性能最高可达 M1 Max 的 3.5 倍,可轻松完成视觉效果、3D 动画和电影配乐等繁重的创意工作量,在 Xcode 中编译代码时,构建性能速度也能高达 2.2 倍。

在人工智能方面,M4 Max 的提升较为明显,可以提供比 M1 Max 快 3 倍以上的神经引擎,配合增大的内存,开发人员可以轻松与具有近 2000 亿个参数的 LLM 交互。

在拓展方面,新 MacBook Pro 也变得更为强大,在 M4 Max 加持下,可以在开盖的情况下,最多外接 4 个额外显示器。

除了核心性能,M4 MacBook Pro 的接口也有所升级。

之前的 M3 MacBook Pro 入门级配备 2 个雷雳 4 接口,现在 M4 MacBook Pro 将从 3 个雷雳 4 接口起步,与更高配置机型看齐,Pro 与 Air 的界限进一步分明;

M4 Pro 与 M4 Max 机型则配备昨天在 Mac mini 上首次出现的雷雳 5 接口,可以实现高达 120 Gb/s 的数据传输速度,吞吐能力是雷雳 4 接口的 2 倍以上。

在新的 MacBook Pro 上,苹果引入了全新的纳米纹理面板,可以在明亮环境中显示高达 1000 尼特的 SDR 内容,并以 1600 尼特的峰值亮度显示 HDR 内容,屏幕旁边的摄像头也升级了——一个支持自动将用户居中的 1200 万像素的摄像头,同时也支持「桌上视角」功能。

最后,苹果宣称新 MacBook Pro 的续航最长可达 24 个小时,并且支持快充,最快只需要 30 分钟就可以充电 50%,续航烦恼进一步得到解决。

苹果向来钟爱于深空灰和银色这类具有光泽感的配色,去年发布的深空黑配色却打破常规,黑得更为深邃,呈现一种强烈而沉稳的金属质感。

以往深空黑色专属于 M3 Pro 与 M3 Max,现在,最便宜的 M4 MacBook Pro 也能享受到这种高级感了。

M4 系列的 MacBook Pro 依然分为 14 和 16 英寸两种规格,其中 14 英寸可选择 M4、M4 Pro、M4 Max 三种性能版本,而 16 英寸可选择 M4 Pro 或 M4 Max 两种性能版本。这样的方案与前代保持一致。

最后,公布一下价格:

14 寸 M4 MacBook Pro :

  • 搭载 M4 芯片起售价为 12999 元
  • 搭载 M4 Pro 芯片的起售价为 16999 元
  • 搭载 M4 Max 芯片的起售价为 26999 元

16 寸 M4 MacBook Pro :

  • 搭载 M4 Pro 芯片的起售价为 19999 元
  • 搭载 M4 Max 芯片的起售价为 27999 元

搭载 M4 系列芯片的 MacBook Pro 将于 11 月 1 日上午 9 点接受预购,11 月 8 日正式发售。

2020 年底,苹果自研的 M1 芯片登场,彼时,大家聊得最多的,还是大数据、云计算和元宇宙。

四年过去,AI 成了目前最炙手可热的话题。

话题永远与产品息息相关,作为苹果最专业的便携终端,MacBook Pro 起步内存集体「升杯」,显然已经为迎接 AI 时代做好了准备。

不过,由于国行版本的 AI 功能的暂时缺席,M4 MacBook Pro 更大的意义也许在于,机身终于来到一个相较前代,定位更清晰、结构更合理、功能更齐全的舒适区。

你会选择 M4 MacBook Pro 吗?你觉得哪个版本是性价比之选?

欢迎在评论区给出你的看法。

让我有个美满旅程

苹果突然发布新 iMac!M4 芯片加持,还有一个惊喜配置

By: 莫崇宇
29 October 2024 at 00:05

就在刚刚,苹果发布了搭载 M4 芯片的新款 iMac。

上代 iMac 搭载 M3 芯片,在去年的 10 月 31 日与 M3 MacBook Pro 一起发布。

现在,新款 iMac 除了处理器升级到 M4,也没有太大变化。

值得一提的是,iMac 的基础款搭载的是 8 核 CPU、8 核 GPU 的残血版 M4 芯片,满血版的 M4 芯片需要选择更高的配置才能获得。

不过,为了迎接 Apple Intelligence,iMac 的起步 RAM 升级到 16GB,最高可升级到 32GB 的 RAM,而此前,M3 iMac 的最高 RAM 为 24GB。

据苹果宣称,搭载 M4 的 iMac 与 M1 iMac 相比,在 Microsoft Excel 等办公任务中的性能提升至 M1 iMac 的 1.7 倍。

对于内容创作者来说,在 Adobe Photoshop 和 Adobe Premiere Pro 等图片和影像编辑应用中处理复杂效果时,新款 iMac 的处理速度可达到 M1 iMac 的 2.1 倍。

在 iMac 机身规格上,iMac 24 英寸的 4.5K 视网膜显示屏提供了纳米纹理玻璃面板的新选择,不过这个选项也不支持基础版,需要更高的配置才能选配。

搭载 M4 的 iMac 现在提供最多四个雷雳 4 接口,同时可以连接最多两台分辨率高达 6K 的显示器,同步支持录音棚级麦克风、六扬声器系统,支持播放杜比全景声的空间音频。

此外,iMac 在配色上也有新鲜——饱和度适中的银、绿、黄、橙、粉、紫和蓝色组成了阵列,供用户根据使用环境选择。

配合 iMac 一起工作的妙控键盘与鼠标则与 iMac 机身颜色匹配,并终于将接口统一为 USB-C,与苹果其他的产品接轨。

价格方面,新款 iMac 售价 10999 元起。

Siri 焕新,苹果牌 AI 终于来了

与新款 iMac 同步亮相的,还有今天即将广泛推送的 Apple Intelligence。

和之前提前上手的爆料别无二致,首批 Apple 智能功能现已面向 iPhone、iPad 和 Mac 用户推出,随 iOS 18.1、iPadOS 18.1 和 macOS Sequoia 15.1 的发布同步上线。

苹果 CEO Tim Cook 表示:

Apple Intelligence 为 iPhone、iPad 和 Mac 引入了一个新时代,带来全新的体验和工具,将彻底改变用户的成就可能性。

其中,写作工具(Writing Tools)集成于 iOS、iPadOS、macOS,提升邮件、信息、笔记、Pages 等应用的语言表现。

Apple Intelligence 支持文本重写和语气调整。校对功能检查语法、用词、结构,并提供编辑建议。用户可总结文本为段落、列表、表格或清单。

升级后的 Siri 也更加自然、灵活。

Siri 增强了语言理解能力,能处理停顿和连续请求的上下文。它还扩展了对 Apple 产品功能和设置的知识,能回答相关问题,帮助用户学习操作技巧。

照片应用程序也将变得更加智能,具备多种新功能。

自然语言搜索让用户可以通过简单描述自己想要的内容来搜索几乎任何事物。此功能也适用于视频,用户可以搜索视频中某个特定片段的事件并直接跳转到该位置。

邮件应用程序新增的「优先消息」板块位于收件箱顶部,显示最紧急的邮件,如当天的午餐邀请或登机牌。

在「备忘录」和「电话」应用中,用户现在可以录音、转录和总结音频内容。

当在电话应用中通话时启动录音,通话参与者会自动收到通知;通话结束后,Apple 智能 会生成一份总结,帮助用户回顾通话中的关键要点。

苹果官方表示,到 12 月,写作工具将变得更强大,比如将晚宴邀请改成一首诗,或在简历中添加更具活力的动词。

12 月还将推出新的视觉智能体验,借助 Apple 智能,帮助用户迅速了解物体和地点。

得益于 iPhone 16 系列的新摄像头控制功能,用户可以立即获取面前餐厅的详细信息并进行互动。此外,摄像头控制还将作为进入第三方工具的入口。

未来几个月,Apple 智能还将引入 ChatGPT 支持、Image Playground 和 Genmoji 以创建自定义表情符号等。

不过,Apple 智能暂时并不适用于大陆,后续我们将会带来一手实测,敬请关注。

实际上,本次 Mac 新品最突出的亮点当属「换芯」。

只是类似于 iPhone,核心性能已经达到了一个高峰,以至于在日常的工作流程和使用习惯中,用户其实不太容易感受到性能提升带来的显著差异。

然而,醉翁之意不在酒,产品「换芯」的真正目的并非仅仅为了提升性能,而是为了更好地服务于 Apple Intelligence。

今年 3 月份,苹果发布了 M3 新款 MacBook Air,当时打出的宣传点正是「全球最适合 AI 的消费级笔记本电脑」,面对 AI PC 的浪潮,即便是苹果也得用 AI 守住市场竞争的主阵地。

不过,对于国行版本的 AI 功能,库克表示仍在「走流程」,其能否为新品带来实质性的提升,目前还是一个未知数。

那么,你会为这次的 iMac 新品掏腰包吗?欢迎在评论区分享你的看法。

我们还年轻,可不想看到这个世界处在毫无自由、隐私的边缘。

就在刚刚, 宣布推出 桌面,向 Plus、Enterprise、Team 和 Edu 用户开放 。

不过,官方表示,目前开放的只是早期版本,将在今年晚些时候向所有 ChatGPT 用户推出「完整的体验」。

刚刚,Windows 版 ChatGPT 正式发布!还有一个实用的新功能| 附下载链接

例如,它还不支持高级语音模式,并且 GPT Store 的部分集成功能暂时也无法使用。

用户可以在微软应用商店 ChatGPT,接着安装即可,安装包大约 110MB,附上下载地址:

The Windows is currently only available to ChatGPT Plus, Team, Enterprise, and Edu users. This is an early version, and we plan to bring the full experience to all users later this year. With the official ChatGPT desktop app, you can chat about files and photos.

系统要求:Windows 10(x64 和 arm64)版本 17763.0 或更高版本。

在具体的使用过程中,OpenAI 提出了一个名为「Companion Chat」的辅助聊天功能,它允许你在不离开当前应用程序的情况下,快速访问和使用 ChatGPT

这个功能类似于一个快捷方式或者浮动窗口,你可以通过特定的快捷键(Alt + Space)来调出这个聊天窗口。

借助这个聊天窗口,你可以快速地向 ChatGPT 提问、上传文件、生成或者开始一个新的对话。它还具有记住上次位置的功能,并且当主应用程序重置时,它会回到屏幕底部中心的位置。

此外,你还可以通过点击窗口顶部的「New chat」来清除聊天内容,或者通过点击「Open in Main Window」按钮将对话转移到 ChatGPT 的主应用程序窗口中继续。

如果不小心关闭了这个聊天窗口,你也可以通过查看侧边栏的聊天记录来在主应用程序中继续对话。

需要注意的是,如果这个快捷键已经被其他 Windows 应用程序占用,那么它将会不起作用,并且也不支持更改快捷键。

目前 ChatGPT 已经向 Windows 两大操作系统开放桌面版本,但 Linux 却没有给出明确的时间表,也惹得不少网友在线催更。

另外,前不久 OpenAI 推出了 ChatGPT Canvas 功能,允许用户与 ChatGPT 合作处理写作或编程任务。

今天 ChatGPT Canvas 也更新了一个比较实用的功能,你可以点击右上角的「Show changes」图标来查看文章或代码的更改。

如下文所示,我使用 ChatGPT Canvas 将朱自清的《背影》改写成文言文版本,点击图标,所做的更改一目了然。

实际上,今天更新的功能也算是补上了 ChatGPT 生态的重要一环。

不过,正如开篇所说,这个桌面版本本质上还是个阉割版,食之无味弃之可惜,尽管快捷键调用方式简单,但网页版所带来的体验明显会更好。

A brief history of the Chooser and printer support

By: hoakley
12 October 2024 at 15:00

How many design and print shops started off with two Macs and a printer, and blossomed with the desktop publishing revolution of the 1980s? Yet when it was first launched, the Mac had poor printer support, and didn’t even have a parallel port, then the standard for office printers. In June 1984, Apple released the first printer designed for the Mac, the dot-matrix ImageWriter with a serial port. The following March came the LaserWriter, featuring PostScript and LocalTalk. The latter was a poor man’s Ethernet, running through an RS-422 port over cheap and simple LocalTalk cabling.

Printer support software was initially primitive, with a small desk accessory named Choose Printer to select which port and driver to use. In System 7 (1991), this became an app in its own right, the Chooser, to handle both printer and network connections.

chooser2001

Printer setup was handled through the Chooser too.

chooser22000

Printer configuration used PPD files for each model of supported printer.

chooser32000

print2file1998

The print dialog supported printing to file as well, although in those days that most commonly generated raw PostScript files rather than PDF.

By 2001 with Mac OS X, printing and networking had become so separated that the Chooser was replaced by the Print Centre, although OS X was still in need of a full print architecture. That arrived in 10.2 (2002) in CUPS (originally the Common Unix Printing System), which had been developed by Michael Sweet.

In Mac OS X 10.3 (2003), Print Centre was replaced by the Printer Setup Utility app, with a pane in System Prefs and later System Preferences. That was initially named Print & Fax, then Print & Scan in 10.7 (2011), and became Printers & Scanners from 10.9 (2013).

printers2006

Printer Setup Utility became increasingly complex. Here it is in Mac OS X 10.4 Tiger in 2006, when it supported a variety of printer connections, and drivers for each of the more popular models from many manufacturers.

printersetuprepair2007

CUPS is powerful and sophisticated, with its own repair feature.

printinstall32001

In 2001, the Network pane was still used to configure AppleTalk, as supported by Apple’s own printers, the last of which had been discontinued in 1999.

printerutility2002

In 2002, Printer Utility still showed its influence from the Chooser.

PrintDialog2001

This is the Print dialog from 2001.

print&fax2010

This is the Print & Fax pane from System Preferences in Snow Leopard, in 2010. Note that this includes a scanner, although the pane wasn’t renamed to Printers & Scanners until 10.9 (2013).

OS X incorporated its own printer drivers as well as those provided by printer manufacturers, a feature that was transformed when Apple introduced AirPrint (in conjunction with Hewlett-Packard) in late 2010, primarily to support printing from the iPad. Although AirPrint didn’t come to OS X until 2012, since then support has grown to become almost universal, over a period in which most printers have become less used, to the point where many now just sit gathering dust.

新 MacBook Pro 提前全球首发,这可能是苹果史上最大的泄露事件

By: 周奕旨
9 October 2024 at 18:01

根据彭博社 Mark Gurman 的消息,苹果将在 10 月底左右发布首批搭载 M4 系列芯片的 Mac,其中包括这些产品:

  • 搭载 M4 芯片的 14 英寸 MacBook Pro;
  • 搭载 M4 Pro 和 M4 Max 芯片的 14 英寸和 16 英寸 MacBook Pro;
  • 搭载 M4 和 M4 Pro 芯片,且具备新设计的 Mac mini;
  • 搭载 M4 芯片的 iMac。

这些产品其实都提前爆料得差不多了,按照惯例,苹果的产品往往会在发布前一段时间以文字描述或模具形式浮现在大众视野中,这甚至可能是苹果公司精心策划的营销策略。

但这一次,让苹果措手不及的是,还未发布的 MacBook Pro M4,在互联网上迎来了自己的全球首发。

▲ 图片来自 YouTube @Wylsacom

事情的开始,源于 @ShrimpApplePro 在 X 上分享了一张图片,看起来像是 MacBook Pro 包装盒背面的产品参数标识。

但一张图片的说服力显然不足,因为大家发现图片中新 MacBook Pro 的包装重复使用了与 MacBook Pro M3 包装正面相同的产品示意图。

▲ 图片来自 X @ShrimpApplePro

关于这张照片的争论还未停歇,YouTube 频道 Wylsacom 丢出了王炸。

▲ 图片来自 YouTube @Wylsacom

没错,这家来自俄罗斯的科技自媒体,直接上传了一个清晰度高达 4K 的开箱视频,犹抱琵琶半遮面的 MacBook Pro M4 就这么水灵灵地出现在互联网上。

▲ 图片来自 YouTube @Wylsacom

在这个视频中,Wylsacom 向观众展示了包装上标签的详细信息。

▲ 图片来自 YouTube @Wylsacom

根据 Wylsacom 使用 Geekbench 测试来看,这台新 MacBook Pro 的跑分数据为单核 3864、多核 15288,比今年上半年发布的 iPad Pro M4 略高,也符合之前测试的 M4 芯片比 M3 性能增加了 25% 的描述,进一步印证了泄露的真实性。

▲ 图片来自 YouTube @Wylsacom

除了醒目的「M4 chip」外,还有几个值得注意的信息。

之前有消息称,未来的 Mac 将会从 16GB 内存起步,按照苹果挤牙膏的习惯来看,这次起步内存的升级应该是为即将到来的 Apple intelligence 的端侧运算做准备。

不过由于不知道这些爆料博主手上的版本是否是入门级的 MacBook Pro M4,所以消息还有待确认。

▲ 黑色的 C to C 线,图片来自 @Wylsacom

内在配置升级了,外部的功能性也没落下,新 MacBook Pro 的接口也迎来了升级。

目前在售的 M3 标准版 MacBook Pro 是 2 个,根据产品标识的小字中描述的「Three Thunderbolt 4(USB-C)」来看,搭载 M4 基础版的 MacBook Pro 将配备 3 个雷雳 4 USB-C 接口,向更专业的机型看齐。

▲ 新 MacBook Pro M4 机身右侧新增的雷雳 4 接口,图片来自 @Wylsacom

之前专属于 M3 Pro 与 M3 Max 的深空黑色也下放到 M4 芯片标准版机型上,覆盖整个 Pro 系列产品线。

在这个视频发布后,知名苹果爆料人,彭博社的 Mark Gurman 在社交媒体 X 上也提到了此视频。

紧跟着 Wylsacom 发布开箱视频的第二天,另一个俄罗斯频道 Romancev 768 也在 YouTube 上传了一条短视频。

在画面里,他向观众展示了一台 14 英寸的 MacBook Pro 包装,根据包装背面的标识显示,这是一台配备 10 核 CPU 与 10 核 GPU M4 芯片的 MacBook Pro,拥有 16GB 内存、512GB 存储空间以及三个雷雳 4 接口以及深空黑配色。

▲ 图片来自 YouTube @Romancev768

东拼西凑下,MacBook Pro M4 在互联网上完成了自己的发布和开箱。

从目前泄露的信息来看,搭载标准版 M4 的 MacBook Pro 终于摆脱了当前在售的 MacBook Pro M3 与 MacBook Air 之间难以拉开差距的尴尬局面,全新的 MacBook Pro 无论在外观设计还是功能性能上都迎来了全面升级,彻底转向专业生产工具的入门定位。

开箱愈演愈烈,但相比这些早有爆料的升级,大家对整个泄露事件的来龙去脉更加好奇。

最初的爆料者 ShrimpApplePro 声称至少有一台 14 英寸 MacBook Pro 是在一个私人 Facebook 群组中出售的。

随后,他又在 X 上继续发帖,进一步描述自己的猜测:

我在网上看到有人在打广告,说有 200 台未发布的 14 英寸 MacBook Pro 要出售,这次泄密也许来源于一个存放新 MacBook Pro 的仓库。

▲ 一位莫斯科的苹果爱好者

苹果上一次在发布前发生如此严重的设备泄露事故,还要追溯到 iPhone 4 时代。

2010 年,一位叫 Gray Powell 的苹果工程师在酒吧庆祝生日后,将还没发售的 iPhone 4 原型机遗忘在了酒吧吧台,捡到它的顾客在察觉到这是一台伪装成 iPhone 3GS 的新手机后,以 5000 美元的价格将手机出售给了科技评测媒体 Gizmodo。

于是,传奇机型 iPhone 4 在还未发布时,就迎来了自己的第一次公开拆解——Gizmodo 详细展示了它的方形金属边框、前后玻璃面板、前置摄像头与 Retina 显示屏。

文章发布后在互联网上引起巨大轰动,占据全球科技界的头条。

随后,苹果正式向 Gizmodo 发送律师函,严肃要求归还 iPhone 4 原型机,并同时向当地警方报案。

加州警方因此搜查了 Gizmodo 编辑 Jason Chen 的住所,检查了他的电脑及其他设备,以调查 Gizmodo 获取这台 iPhone 原型机的过程。

面对这些举措,Gizmodo 表示他们是以新闻的身份购买并报道这一事件,并确认该设备属于苹果,在短时间内将其归还,与此同时,警方也证实,这台原型机确实是苹果员工 Gray Powell 在酒吧遗失,而非故意泄露,因此这起事件被定性为「遗失设备」而非盗窃。

此事一度引起了关于新闻自由的争议,但所幸最终没有人因这起事件被起诉或被追究刑事责任,iPhone 4 甚至因祸得福,受到了极高的关注,在两个月后的发布会上,受到市场的热烈欢迎,成为了当时最畅销的手机之一。

▲ iPhone 4 发售后,人们排队购买的盛况

此后,苹果大幅升级了内部保密措施,包括加强对原型机的保护、限制测试设备的使用范围,以及对参与新产品开发的员工进行更加严格的保密培训,但同时,苹果也也找到了维持热度的方法,开始改变严防死守的政策,逐渐放宽了新品在社交媒体上提前爆料的尺度。

不过,这一次 MacBook Pro M4 泄露的性质更甚于此,不仅规模远胜于十四年前,还更像是一场有计划、有盈利的实物泄露。

面对这样大批量、高曝光度的恶性泄露事件,苹果如何通过法律手段追责涉事者固然重要,但眼下最要紧的,是在舆论的风暴中迅速采取行动。

或许趁着目前居高不下的关注度,提前启动这场未定日期的发布会,是苹果四两拨千斤的最好选择。

Which firmware should your Mac be using? (version 9, Sequoia)

By: hoakley
23 September 2024 at 14:30

This article lists the firmware versions of Macs that have been successfully upgraded to run macOS 15.0 Sequoia.

Apple doesn’t provide an official list of the current firmware versions which should be installed on each model of Mac. That displayed for Intel models uses five decimal numbers separated by dots, e.g 96.0.0.0.0, and is given below. Models with T2 chips consist of two parts, the second covering iBridge in the T2. Apple silicon Macs are different again, and give an iBoot version instead, as they don’t use EFI at all.

Macs still running older versions of macOS are covered by information at:

Apple Silicon Macs

The current iBoot version is 11881.1.1.

Intel Macs with T2 chips

The current EFI version is 2069.0.0.0.0 and iBridge is 22.16.10353.0.0,0.

Intel Mac without T2 chip

iMac: iMac19,1 2069.0.0.0.0

Apple Studio Display

The current version remains 17.0 (build 21A329).

T2 chip models:
The iMac Pro, 2019 Mac Pro, iMac 27-inch 2020, 2018 MacBook Pro with Touch Bar (MacBookPro15,1 and 15,2), 2018 Mac mini and 2018 MacBook Air, and their successor models, use a different mechanism for firmware updates, managed by their T2 chips.

How to check your Mac’s firmware version

The simplest way now is to run either of my free tools SilentKnight or LockRattler, available from their product page.

Alternatively, use the About This Mac command at the top of the Apple menu; hold the Option key and click on the System Information command. In the Hardware Overview listing, this is given as the Boot ROM Version or System Firmware Version.

What to do if your Mac’s firmware is different from that shown

If the version is higher than that given here, it indicates that Mac has installed a more recent version of macOS, which has installed a later version of the firmware. This is almost invariably the result of installing a beta-release of the next version of macOS. This occurs even when the newer macOS is installed to an external disk.

If the installed version of firmware has a version which is lower than that shown, you can try installing macOS again to see if that updates the firmware correctly. If it still fails to update, you should contact Apple Support.

Firmware updaters are now only distributed as part of macOS updates and upgrades: Apple doesn’t provide them separately.

Older versions of macOS provided the command tool eficheck at /usr/libexec/firmwarecheckers/eficheck/eficheck to check firmware version and integrity. That was removed from Sonoma. All T2 and Apple silicon models automatically check the integrity of their firmware in the early part of the boot process anyway. If any errors are found then, the Mac should be put into DFU mode and firmware restored from the current IPSW image file. In Sonoma and later this can be performed in the Finder, and no longer requires Apple Configurator 2. Full instructions are now provided in this article. If you don’t have a second Mac or don’t feel that you can perform this yourself, it should be easy to arrange with an Apple store or authorised service provider.

A brief history of QuickDraw and PICTs

By: hoakley
21 September 2024 at 15:00

The original Macintosh running Classic Mac OS was dependent on a great many components, but the most important of all was its graphics system QuickDraw. Without that, none of the windows, icons and images that were composed into its human interface would have happened. Although almost everything from QuickDraw has now been superseded and removed from modern macOS, you can still open most of its QuickDraw images saved in its custom format, PICT.

QuickDraw

QuickDraw was originally written by Andy Hertzfeld (b 1953) and Bill Atkinson (b 1951), who devised a remarkably innovative raster-based system, and implemented it to perform exceptionally well on the limited hardware available, starting with an 8 MHz 68000 CPU with only 128 KB of memory. It’s based around a logical drawing area called a GrafPort, which can be that within a window, the whole Desktop, or somewhere off-screen.

GrafPort coordinates set their origin at the top left and are signed 16-bit integers, giving a range of -32,767 to +32,767. Coordinates refer not to the pixels within the GrafPort, but to the infinitely thin lines between them. When drawing along a line between two coordinates, the thinnest line shown is a series of pixels below and to the right of the line. Pixels are square, and their default resolution conforms to the printing standard of 72 pixels/points per inch, just over 28 per centimetre. These were essential, to ensure that what you saw on the Mac’s display was what you got from the printer, WYSIWYG.

QuickDraw has commands to support a good range of graphics primitives, but Bill Atkinson’s stroke of genius was the data structure known as a Region, an arbitrary set of pixels that didn’t even have to be contiguous. Although initially constrained to 32 KB of memory, rising later to 64 KB, Regions can be combined with others, differenced, and manipulated in other ways. Their internal structure remains largely opaque, apart from the technical description used by Apple in its patent.

Picture and PICT

The other key data structure in QuickDraw is a Picture, the series of QuickDraw operations called to generate or manipulate images within a GrafPort. Those can be recorded, and played back later to repeat generation of that image, perhaps in a different GrafPort and coordinates. Rather than standardise on a raster graphics file format, QuickDraw saves Pictures in PICT files.

Initial releases of QuickDraw only supported black and white images, although limited colour support was added to work with Apple’s four-colour dot-matrix printer, the ImageWriter II of 1985. For the release of the Macintosh II in 1987, QuickDraw was extended to Color QuickDraw using CGrafPorts with 8-bit video cards. It was later enhanced to support 32 bits per pixel, in what is commonly known as 32-bit QuickDraw. The PICT file format had a similar journey. Originally, it only supported eight colours in PICT 1, then PICT 2 brought 24-bit colour and greyscale.

Examples

Here are some examples of QuickDraw graphics from Mac OS 9 in 2000, each converted from its original PICT screenshot taken 24 years ago.

qdfreehand

This is Macromedia (also Aldus) FreeHand, then a competitor to Adobe Illustrator, before it was finally killed by Adobe in 2003.

qdconceptdraw

This is Computer System Odessa’s ConceptDraw, then a new product, and still available for macOS.

qdstrata3d

This is Strata 3D, a high-end 3D modelling app first released for the Mac in 1988 and still available.

qdcvgs

This is a typical role-playing game of the day.

qdxplane

This is X-Plane flight simulator by Austin Meyer of Laminar Research, first launched in 1995, and still going strong with support for Apple silicon Macs.

Quartz

Apple adopted a new graphics system for Mac OS X, although to begin with 32-bit Colour QuickDraw was retained in its Carbon API. Its replacement, Quartz, is built around PDF 1.4, but performed poorly until Quartz 2D Extreme in Mac OS X 10.4 (2005) offloaded its rendering to early GPUs. With that, QuickDraw was deprecated, and support successively removed, although there are still some graphics apps like GraphicConverter that can open and convert PICT files. Preview used to be able to as well, but that too seems to have been removed.

Documentation

You can still read Apple’s detailed guide to QuickDraw, Pictures and PICT files in Imaging with QuickDraw, which also gives you an idea of the depth and quality of Apple’s documentation in the past.
