Alright, so I'm having trouble deciding if I should upgrade my Late 2009 iMac to El Captain. Info: Late 2009 iMac 21.5 inch Mavericks, 10.9.5 3.06 GHz Intel Core 2 Duo 4GB 1067 MHz Ram HDD - no SDD Should I upgrade? Because I know that the late 2009 iMacs are the last officially recommended machines to upgrade. And I really don't want this machine to get any slower. Now, I'm not really in the known and haven't kept up with the news etc. lately. What do you guys think, should I upgrade to El Capitan or not? I'm assuming Yosemite is out of question. And I'm hoping this is in the right sub forum, if not please let me know! Thanks in advance!
