What is my best upgrading option and, if it is not High Sierra, how can I upgrade to an older version since they are no longer available from Apple, yes? Jun 22, 2017 Wireless web testing conducted by Apple in October 2011 using preproduction 2.8GHz dual-core Intel Core i7–based 13-inch MacBook Pro units. For example, for Mac OS X 10.7 Lion, released in mid-2011, Apple notes that an “Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor” is required, but not which models; 2GB of RAM is. Best Mac OS for Mid-2012 15' Macbook Pro. And install fresh OS. Which OS version would you recommend which will still keep it running well for atleast next 2 years. I mean the best compatible.
I recently had to re-install the original OS from the discs that came with my MacBook Pro. This installed Snow Leopard and software updates have taken it to 10.6.8
However it refuses to upgrade to Lion, Mountain Lion or Mavericks. (I've tried them all a few times).
I have repaired permissions and checked the HD is OK (which it is).
Each time I try to upgrade it takes me to disk utilities. The only way out is to quit and restart in 10.6.8
Mac Os Version 10.13
Does anyone have a tip on how I can upgrade again? It used to run OS X Sierra quite happily.
