I inherited a like new base model 13" mid-2011 i5/128/4. It's still running Lion with approximately 65 battery cycles. Windows user bought it, tried it for a while, and put it back in the box.
It's snappy on Lion but I'm wondering if I should update the OS to gain more features. For those who have updated, which OS would run the best without losing functionality?
Version 10.8: Mountain Lion
Version 10.9: Mavericks
Version 10.10: Yosemite
Version 10.11: El Capitan
Thanks in advance.
I would go with Mavericks. I have a MBP Late 2013 and after using all the OS listed above I always end up reinstalling Mavericks for these reasons.
-Battery life is excellent on Mavericks.
-It has maps on it.
-It needs less requirements to work smoothly.
-I don't need some of the features that Finder has on Yosemite and El Capitan.
The only thing that bothers me sometimes is the fact that Airdrop is pretty bad on Mavericks but other than that I am super happy with Mavericks.
