Hey,
I recently upgraded my iMac to high sierra and it has caused problems.
1. The computer randomly wakes from sleep and shows the desktop in a
weird blue colour. I have attached the normal and blue colours for
comparison.
2. When it wakes, it drops the internet connection on wifi, and I need to turn the wi-fi off and back on, then it's fine.
Can anyone please help? It's driving me mad. Thanks
iMac 27" 5K, macOS 10.14
Safe Boot from the HD, (holding Shift key down at bootup), does the problem occur in Safe Mode?
To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account?
