Im debating on upgrading to the new OS. I have a 2009 MBpro 2.66ghz intel core 2 duo, 500 gb Hd (no SSD), 4 GB ram (planning on bumping this up to 8 Gb very soon). Just wondering if anyone here has any input on performance with the new OS. I would really like to get a newer Macbook but dont have the money right now. Not really a fan of the new look of the OS but I figure I have to upgrade sooner or later. Mostly worried about performance though.
