Why after upgrading iMAC to Yosemite OS X 10.10.4 Energy Saver function to "Never Sleep" still sleeps & still can't backup to Time Capsule?
Why is this known issue not answered on any Apple pages I've come across?? We are we not able to keep our Yosemite 10.10.4 iMac OS X from SLEEPING. I've followed all the instructions... Rebooted, unplugged, turned all devices off, etc...Any answers? I need to backup my imac and other MacBooks! Plus, want to keep one computer from sleeping so that we can BACKUP and have the 'rules' work across all the devices. Help!
iMac, OS X Yosemite (10.10.4), iMAC and Macbook Pro 12" Gold
