how do you purge a purgeable disk in disk utility

This is NOT true...

I have posted in previous threads and provided images...

Fact...it does not automatically release purgeable space, I can no longer work as Google Drive recognizes the boundary. I rose at 5am to deal with a deadline and now it's 6am and I messing with this.

PLEASE do not tell me that it works.

Can we deal with the issue please HELP ME !

How do you activate the purge on the identified space in disk utility.

The answer to your question is if you have enabled Optimize Storage, the storage identified as "purgable" will be automatically deleted from your Mac when that space is required, but those deleted items will remain available to download once again to local storage should you require it. Those features are explained in the Apple Support documents provided.

You do not need to take any action to remove files identified as "purgable".

To free up space on your internal drive activate as many options that you are comfortable with. Purgable files are little used files that can be saved to iCloud, trash that can be automatically removed by the OS, little accessed media files purchased through iTunes which can be removed from the internal storage & automatically downloaded next time they are accessed, etc.

This is not so...disk space is not freed up...as described.

All prescribed actions have been taken to no effect.

It appears that iCloud requires commensurate space in order to swap/purge space and I am surely not going to buy disk space from Apple.

Is the freeing of purgeable space dependent on my using ICloud for storage, because I do not?
