Why does my available storage keep increasing/decreasing?

[dkupras]

Hi All - Is there a way I can find out why my Mac storage continues to decrease and then increase at random times when I haven't made any changes?

Sometimes I will restart the machine to find the available storage at the same amount prior to the restart however within a few minutes to an hour it will go back up.

Are there any good free tools aside from Dr. Elite etc that can clear my machine a bit better?

Thanks!

Dave

It's because of TM Local Backups. The system will automatically delete them if space is needed. There's an Apple support document about it and threads on here too.

You didn't make any change, but the OS did. May be TM, may be finder indexing, my be analysing the Photos library... And the OS need to write something (or delete something) after the job complete. Those temporary backup, index files, caches... can be in GB size.

Thank you all!
