The WWDC keynote told us that the Mobile Time Machine on High Sierra will now leverage the APFS's snapshots feature. A few questions:
1) Where are the snapshots actually located? On Sierra, there was a hidden folder called /.MobileBackups. Is there a similar folder on High Sierra?
2) Will High Sierra use a similar policy on local TM snapshots, i.e. treat them like temporary files ("purgeable") and automatically remove them in part or fully, when the user runs low on disk space? Will the snapshots be removed after syncing with the external persistent storage such as Time Capsule?
3) Is there a way to turn on and off the local TM snapshots? On Sierra, there was "sudo tmutil enablelocal" but it's no longer supported.
