I have been given an Apple Mac, from my father in law. Not sure how old it is, I know he had it for quite a few years before upgrading to a newer and bigger model. Anyway, I don't know anything about these machines, and it seems to work faultlessly, but it won't update. I opened About My Mac, and it's running Mac OS X, version 10.6.8, processor 3.06 ghz intel core 2 duo, Memory is 4Gb 1067 MHz ddr3. So, i'm guessing Apple no longer support these models, and I guess the question is, Can you update it to run current versions some how? is there a special procedure? or am I now the proud owner of an Apple Mac decktop brick?
