告诉HN：macOS支持即时快照回滚
我今天发现了这个，感到非常惊讶，所以想和大家分享一下。
显然，你可以进行完全重置，然后使用迁移助手从备份中恢复。这可能需要半个小时，而且过程比较麻烦。
但你也可以进入恢复模式，选择“从时间机器恢复”，然后选择一个最近的快照（包括每小时的“本地快照”），并回滚到那个状态。这只需要几秒钟（以及重启一次），你的Mac就会恢复到之前的状态。

I discovered this today and was quite surprised, so I thought I'd share.<p>You can obviously do a full reset and then use Migration Assistant on a backup. This might take a half hour and it's a hassle.<p>But you can also boot into recovery, go in "Restore from Time Machine", pick a recent snapshot (including hourly "local snapshots"), and roll back to it. It takes seconds (and a reboot) and your Mac is now rolled back to its previous state.
