Mac runs slow and freezes since installing Snow Leopard
I have an early 2008 iMac with 3GB RAM. Since upgrading to Snow Leopard I have had problems with freezing and slow running.
Someone in my local Apple store recommended Lion for my age machine, but I can find only Mountain Lion now.
Is it still possible to get Lion, or would Mountain Lion fix the problem?
