iMac Running Slowly - What can I do to speed it up?
My iMac is running slowly and I spend a lot of time looking at the spinning wheel.
Should I expect this looking at the overview? It seems early as it's only 3.5 years old and doesn't really get used heavily - See overview screen shot below
Should I expect this from the storage use? - see screenshot below.
What can I do to improve the speed my machine is running at?
Many thanks in advance.
p.s. - APOLOGIES if this post is riddled with obvious quick fixes.
