After I updated to OS 10.14.4 a day or two ago, my late 2013 27" 3.2.GHz iMac with 24 mb RAM will not wake from sleep. The screen remains black, with a cursor arrow, which sometimes turns to the spinning ball, which sometimes stops spinning. In any event, I have to shut down using the power button, and restart. I tried running MalwareBytes, and Onyx maintenance, no change. I reset PRAM as that was mentioned elsewhere, without effect. Has anyone else experienced this with the newest OS update? Any suggestions?
