My Mac is playing up.
Dear good people,
Yesterday I updated my iMac and ended up with a dark screen.
Apple Support recommended me downloading and reinstalling the latest O.S.
This morning I still can’t get my Apple to behave normally.
I have no option other than to take it into a local Grants Pass computer technician and see if he can make sense of the issue.
In the meantime normal service will be somewhat curtailed.
