MacOS – Set the screen saver to 20 minutes

configurationmacosscreensaversettings

I set 20 minutes in System Preferences -> Desktop & Screen Saver, however the screen saver starts after 5 minutes. I tried to log out and restart the mac with no success.

I should say that after restarting I can see 5 minutes again. So it looks like the settings were not saved.

Check the date for the file: com.apple.screensaver.50A10F0D-581E-5D09-8966-646EE8532C5B.plist in Libary

after you made the time change, it should show the latest date/time.

If not, delete the file.

MacOS – Why is the screen saver not kicking in

I cannot tell about screensaver for sure, but you can use pmset -g to show which process is disturbing sleep (think this first appeared in 10.6.7)

# pmset -g
[cut]
sleep       0 (imposed by 1517)
[cut]

this means that pid 1517 is preventing the system from sleeping.

# ps ax |grep 1517
1517   ??  Rs     1:59.76 /System/Library/CoreServices/backupd

This shows that this is the backup daemon running.
