10.10.4 Keyboard not working after prolonged sleep
Title says it all.
Since upgrading to 10.10.4, I find I cannot use the keyboard to wake my computer up after a prolonged sleep. I have to perform a forced reboot.
I saw there was a similar problem for Mac Minis .. and a patch was issued. I'm not finding anything for my iMac though.
Any help?
iMac, OS X Yosemite (10.10.4), 2.93 GHz Intel Core 2 Duo, 8 Gb RAM
