    Anyone work out how to get macOS HS to stop local snapshots?

    Using the sudo tmutil disablelocal command in terminal gives the following.

    Looks as though the command has been removed.

    I am guessing that Apple removed this functionality, as Time Machine is not supported on APFS. If local snapshots are based on directory hard links too, then this wouldn’t work.

    You can use TM if the TM drive is HFS even if the OS is APFS.

    It won’t work if the TM is APFS though.

    Yes, but local snapshots may be relying on the same technology as Time Machine, making it incompatible with an APFS-formatted Mac disk. Apple may have decided to remove the feature altogether in anticipation of a replacement for Time Machine in the future.

    Time Machine works, local Snapshots are also working. I don't know if APFS has anything to do with that, but as far as I understand he wants to disable local snapshots (what really should work) and not enable them. I don't see the reason why they should've removed that option.

    This should do the trick:
    Code:
    sudo defaults write /Library/Preferences/com.apple.TimeMachine MobileBackups -bool FALSE
    Maybe you have to restart your Mac (or the Time Machine daemon) afterwards.

    Thanks. Can you confirm the word bool is correct?

    No need to deactivate this as local snapshots on APFS barely use up any space. This now uses the snapshotsfeature included in APFS.

    Local snapshots in 10.13 use the new APFS volume snapshot features, meaning extremely quick snapshots with barely any disk usage. Apple has demoed this at the WWDC. Its very impressive, really. Waiting for this to come to server-side TM (but it will probably take another year).
