macOS Catalina is here and available for download, and you’ve no doubt heard all about the breakup of iTunes and the new consumer-oriented entertainment apps shipping with the system.
macOS Catalina可以在此处下载，您无疑已经听说了iTunes的解体以及系统附带的面向消费者的新型娱乐应用程序。
But what do developers, designers, and other tech professionals need to know? We run through the key points.
但是开发人员，设计师和其他技术专业人员需要知道什么？ 我们贯穿关键点。
Are you relying on some older, obscure native app for a specific function, as so many developers and designers do? Your Catalina update could throw you a wildcard: it’s the first macOS release that drops support for 32-bit apps.
您是否像许多开发人员和设计人员那样依赖某些较旧的，晦涩的本机应用程序来实现特定功能？ 您对Catalina的更新可能会给您带来通配符：这是第一个放弃对32位应用程序的支持的macOS版本。
During the setup process, you’ll be given a list of installed apps that will no longer open after the update. If you want to keep using that tool, it’s time to hit up the developer for a long-overdue update… or stay on Mojave for a while longer yet.
在设置过程中，系统会为您提供已安装的应用程序列表，这些列表在更新后将不再打开。 如果您想继续使用该工具，该是时候请开发人员进行早就应该进行的更新了……或者在Mojave上呆了一段时间。
Mojave brought iOS ports of the News, Stocks, Voice Memos and Home apps to macOS. In Catalina, Apple is opening the tools that enabled these ports up to developers under the name of Catalyst.
Mojave将新闻，股票，语音备忘录和家庭应用程序的iOS端口引入了macOS。 在Catalina，苹果公司以Catalyst的名义向开发人员开放了支持这些端口的工具。
While this doesn’t directly affect web development work, it does make iOS a more attractive native development platform, which may inform your future platform choices. And if Apple’s plan to reinvigorate stale macOS third-party app development with some of the action from iOS works, you could incorporate better productivity and development apps into your workflow in the near future.
虽然这不会直接影响Web开发工作，但确实使iOS成为更具吸引力的本机开发平台，这可能会为您将来的平台选择提供依据。 而且，如果Apple计划通过iOS的一些措施来振兴过时的macOS第三方应用程序开发的计划，那么您可以在不久的将来将更好的生产力和开发应用程序整合到您的工作流程中。
For now, Catalyst is available to developers of iPad apps — we expect that to broaden in the future.
目前，iPad应用程序的开发人员可以使用Catalyst，我们希望这种情况会在将来得到扩展。
Catalina offers accessibility improvements in the form of improved Voice Control for those who have difficulty seeing, or using keyboards and mice.
Catalina为视力困难或使用键盘和鼠标的人提供了改进的语音控制形式的可访问性改进。
Of course, developers should ensure that their apps work as well as they can with this tool, because it’s the right thing to do.
当然，开发人员应确保自己的应用程序使用此工具运行良好，因为这是正确的选择。
Developers are known for their love of keyboard shortcut mastery, but no doubt the ability to create custom commands has inspired determined lifehackers. What if you never had to take your cursor or eyes off of VS Code to run other frequent workflows?
开发人员以热爱键盘快捷键而闻名，但是无疑，创建自定义命令的能力激发了坚定的救生员。 如果您不必从游标或视线移开VS Code来运行其他频繁的工作流怎么办？
We look forward to seeing what the community comes up with.
我们期待看到社区的想法。
Do you waste too much time using your computer for mindless entertainment, forcing you to stay up late making up the time productively?
您是否浪费太多时间在计算机上进行漫不经心的娱乐，从而迫使您熬夜熬夜，从而浪费了很多时间？
Or are you a workaholic who just can’t find the will to shut off and disconnect?
还是您是一个工作狂，只是找不到切断和断开连接的意愿？
If you’re like most of us in the industry, you’re a mix of the two. Catalina introduces a variant of the Screen Time app that’s been on iOS for a couple of years now.
如果您像我们行业中的大多数人一样，那么您就是两者的结合。 卡塔琳娜(Catalina)推出了Screen Time应用程序的一个变体，该变体已经在iOS上使用了两年了。
Screen Time for macOS provides you with visual analytics that help you understand the way you’re spending time on your device, which can often lead to some unexpected epiphanies. It also lets you schedule downtime, forcing you off the computer and into the real world at the right time.
macOS的“屏幕时间”为您提供了可视化分析，可帮助您了解在设备上花费时间的方式，这通常会导致一些意想不到的顿悟。 它还使您可以安排停机时间，迫使您在适当的时间离开计算机进入现实世界。
As with iOS, you can also set time limits for specific apps, and there are some ways to moderate your web content usage without outright blocking your web browser from opening.
与iOS一样，您也可以设置特定应用程序的时间限制，并且有一些方法可以在不完全阻止网络浏览器打开的情况下调节网络内容的使用。
For developers, designers, and all other web professionals, the real headline feature of Catalina is Sidecar. Sidecar turns your iPad into a secondary display for your Mac, and it’s really easy to enable (provided you have the requisite tablet, which is not included with the operating system update).
对于开发人员，设计师和所有其他Web专业人士来说，Catalina的真正标题是Sidecar。 Sidecar将iPad变成Mac的辅助显示器，并且真的很容易启用 (前提是您拥有必需的平板电脑，但操作系统更新中未包含该平板电脑)。
The best reason to use Sidecar over a standard display is Apple Pencil integration. Designers will love the ability to draw directly on the screen when using Sketch and Illustrator without switching devices all the time. You can even mirror your Mac’s screen if you’d like an unobstructed view of what you’re sketching on one side.
在标准显示器上使用Sidecar的最佳理由是Apple Pencil集成。 设计人员会喜欢使用Sketch和Illustrator时可以在屏幕上直接绘制而无需始终切换设备的功能。 如果您希望在一侧一览无余地查看草图，甚至可以镜像Mac的屏幕。
Most of us will use Sidecar as a place to dump Slack or a terminal window, but in any case, it’s clear it’ll be the most beneficial update for many of us.
我们大多数人都将Sidecar用作转储Slack或终端窗口的地方，但是无论如何，很显然，这对于我们许多人而言将是最有益的更新。
Let us know how you went with the upgrade, and what you’ve enjoyed most so far. We always recommend waiting a few days for the bugs to shake out — especially with Apple’s recent track record — but initial reports suggest the release version is pretty solid after all.
让我们知道您如何进行升级，以及到目前为止最享受的是什么。 我们始终建议您等待几天，以便这些错误消失(尤其是与Apple的近期记录有关)，但初步报告表明该发行版本毕竟非常可靠。
