PRINTER
I have downloaded a new printer under my user for my new iMac , seems as if i must downloaded to each user under each user login. Is there a way around this?
iMac with Retina 5K display, OS X El Capitan (10.11.3)
Did you set it up in the System/Printers & Scanners preference pane? Once that's done it should be available to all users on the iMac. You may have to reboot to get it active.
