A Mac mini 2011 running Yosemite (as of today) running extremely slow. When using either Safari or Firefox, always a constant "Wheel of Death" while surfing.
Interesting enough, had a second Mac mini that was doing a similiar thing, upgraded to the newest Flash, problem solved.
However the first problem Mac mini is still having severe wheel of death problems and slowness. I have upgraded to newest Flash, Java and even to the newest OS Yosemite - nothing has worked.
This Mac does have 5 user accounts on it. It could be possible to remove up to 2 accounts if needed.
Any solutions to fixing this??? Or just reinstall the OS from scratch and reinstall the user profiles?
