How do I find out how long Undo backups last?

The Undo feature in Mac Optimizer saves a backup each time you perform a task. By default, these backups are deleted after ten days.

To adjust this number:

• Under the Mac Optimizer menu, click Preferences…
• Change the value in Remove Backups after 10 Days Automatically.

Note that increasing this value can negate some of Mac Optimizer’s space-saving features, as backups take up space of their own.
