Currently I am using a 2011 iMac. While it does still work, it s slow. Sometimes to get wifi active I have to turn it off and then back on again.I've been told that probably my wifi card is fading. While I'm a mac fan , I'm considering a PC. It will depend on the iMac refresh specs and cost.If I can get a better specced PC for the same price, that s where I'll head.
