iMac suddenly won’t finish loading
I turned on my iMac to find it won’t finish opening and freezes on the full loadbar screen. It will boot up to a point fast and then suddenly slow and then freeze on full after so long.
I am up todate on my updates.
It is a 2013 model.
I have tried unplugging and waiting, disk utilities to use first aid, etc. nothing has fixed it.
Is there anyway I can save my drive to an external before trying to erase the memory or take it in to be looked at if all else fails?
Apreciate the help. Thank you.
iMac, OS X El Capitan (10.11.6), Late 2013
