Slow file saving and app loading on macOS Tahoe

Since upgrading to Tahoe, I have experienced FILE SAVE that take so long that the app can time out, and I have to "ignore" it. Also when loading some apps, it takes a LONG time to load them.


What can I do to rectify this.

It is possible there are processes running in the background that are using significant resources. Check Activity Monitor, CPU tab, sort by % CPU to see what's running hard.

See if the problem is present when you boot in safe mode, which disables 3rd party extensions and performs some system cleanup.
