I have a late 2009 iMac 3.06 GHz Intel Core 2 Duo. If I upgrade my OS to OS X Mountain Lion, will this make my Mac run slower?
I have a late 2009 iMac 3.06 GHz Intel Core 2 Duo, which is currently running Mac OS X 10.7.5. If I upgrade my OS to OS X Mountain Lion, will this make my Mac run slower? Will it cause lag?
Thanks!
