恢复软件的正式版本

To use a previously-released OS version, you can erase your device, then restore from the backup that you created before you installed the public beta. You can also restore shipping software on your Apple TV using iTunes on your computer and then re-download any purchases.


1

为您想要保留的文件制作副本。

因为将要使用您在安装 Public Beta 版前创建的备份来进行恢复,上一次备份后创建或修改的任何文件在恢复时将不会保留。若要为这些文件创建副本,请打开“访达”并选择您要保留的文件。然后将这些文件拖到其他储存设备中(如 USB 拇指碟或外置磁盘)。

2

Turn off Find My Mac

Open System Preferences, select Apple Account. Uncheck Find My Mac, and enter your Apple ID password.

3

重新启动进入“macOS 恢复”。

Go to the Apple menu () and select Command (⌘) and R keys. Release the keys when the Apple logo appears. Reformat and partition your startup disk.

4

重新格式化并给启动磁盘分区。

Before restoring from your Time Machine backup, you must first partition and reformat your startup disk. Partitioning your startup disk permanently deletes all of the data stored on it.

To begin, select Disk Utility from the macOS Utilities window in macOS Recovery, then select your startup disk. Be sure you are selecting the entire disk (not the volume name indented beneath it), by selecting View > Show All Devices, then select the disk and choose Partition. If prompted to add a volume to the container or partition the disk, choose Partition.

Disk Utility will present a pane where you can configure your partition. Under Format, choose APFS if you are restoring a Time Machine backup of macOS Mojave or later. Otherwise, choose Mac OS Extended (Journaled). Then choose Apply.

When done, quit Disk Utility to return to the macOS Utilities window.

5

重新启动进入“macOS 互联网恢复”。

确定您的备份驱动器已连接。然后前往苹果菜单 () 并选择重新启动。当 Mac 重新启动时请按住 Option、Command (⌘) 和 R 键。直到出现 Apple 标志时松开按键。

6

从您的时间机器备份进行恢复。

You will be presented with options from macOS Utilities. Select 'Restore From Time Machine Backup', then choose Continue.

7

选择备份。

请按照屏幕说明指定要使用的备份,并开始恢复进程。选择备份时,请使用“macOS 版本”栏来验证所选择想要恢复的版本为之前发布的版本。

8

从备份恢复。

After you choose Restore, Time Machine begins restoring your Mac to the way it was the day you created the backup, and before you installed the macOS public beta.

9

拷贝任何附加文件。

恢复完成后,将步骤 1 中的文件拷贝到系统。
