Old MacBook Air 11" upgrade help
Hi. My MacBook Air 11" is dated mid 2011. Been stuck on High Sierra for years. Tried upgrading but wouldn't work. So, I can't upgrade most apps either. I was wondering whether someone could help figure out how to do it by myself. Or, does the Apple Store do any upgrades (software or hardware) if I bring my laptop in? Or, is my laptop too old for any upgrades at all?
My laptop specifics:
MacBook Air (11-inch, mid 2011)
masOS High Sierra
Version 10.13.6
Processor 1.6 GHz Intel Core i5
Memory 2 GB 1333 MHz DDR3
