Solved - My new MacBook Air M2 was struggling with downloading and installing Xcode. The problem, I think, was that the laptop sleeps after a short period of time and that stops the download/install process. Download/install restarts at 80% or 0% when the laptop is reawakened - repeat. A simple way to avoid the laptop from sleeping is to open the Terminal application (Application/Utilities/Terminal) and type "caffeinate". That prevents the laptop from sleeping and lets the download/install process complete itself. When done type control-c into the Terminal and it will quit caffeinate.

这是现在每个人在AppStore安装时都会遇到的奇怪行为。而不是从苹果开发者帐户下载所需的xcode版本并安装。

请参考以下链接下载XCode版本。

所有版本的Xcode下载链接。

以上链接包含XCode 1.0至最新版本的下载链接。

我在M1 macbook pro上更新了Xcode，有很多内存和SSD, MacOS 12.1从12.2升级到12.3。花了4.5个小时。所以耐心和观察日志是有帮助的。

最好的方法是在Mac上打开“控制台”(不是终端)应用程序，在搜索栏中输入“app Store”，然后按下“go”按钮

你会开始看到线条进来，你需要让它足够宽，这样你就能看到零件编号，并注意到进度，就像第二张截图一样

你会注意到有些数字移动得很快，有些则需要10分钟，但至少你知道你没有“卡住”!

我被困在完成:1000中的808。

这是变通方法。

App store应用程序屏幕的左下方，有一个帐户按钮。

按帐户，然后你会看到你应该接受的信息。

按“accept”，输入iCloud密码。

然后魔法。控制台的应用商店日志数量正在上升。
