Question: macOS High Sierra has lagging when switch spaces from mouse swipe

After upgrade to high sierra, it has problem when switch spaces.

It's fine speed changing spaces from keyboard shortcut or dock icons, but there is lagging when switch from mouse two finger swipe.

I can't understand why it happens.

Anybody has same problem with this?

iMac, macOS High Sierra (10.13.4), null

Answer:
Answer:

A Safe Mode boot deletes system caches that can help after updating or upgrading macOS.



To start up in safe mode:


  1. Start or restart your Mac, then immediately press and hold the Shift key. The white Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
  2. Release the shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.


To leave safe mode, restart your Mac without pressing any keys during startup.


See if that makes a difference.
