I've got a mid 2010 C2D Mini w/ 8Gb of RAM. Will this run Mavericks OK? Is there any reason not to upgrade?
I have been debating the same thing while I consider upgrading from 10.8.5 ML. What version of OS X are you running now? If you are still using Snow Leopard and expect to maintain compatibility with older OS X programs and device drivers when you switch to Mavericks you will be in for a big surprise. If you don't care about running older programs or older devices then it might be worth upgrading. Do your Time Machine backup(s) before the upgrade. You might also want to post in the MacRumors Mavericks forum for extra suggestions.
Currently running Mountain Lion (10.8)
So if you buy a new mini off apples website what does it come with, Mavericks?
What happens if you buy a apple refurbished mini do those come with Mavericks also?
The new Minis will have Mavericks. For the refurbs, the late 2012 will have ML while the 2011 models will come with Lion installed.
My Early 2009 Mini that I upgraded to 8GB of ram runs Mavericks as does my Late 2010 MBA. Upgrade it, you won't regret it.
