My Macbook Air from mid 2011 has 2 GB RAM, its processor is 1.6 GHz i5, 64 GB of flash storage. Its OS is the one it had originally, Lion.

Many apps require to upgrade the OS - e.g Slack. Yet I don't think going for Sierra with 2 GB RAM is a good idea, and I can't upgrade the RAM as it is impossible on new Macbook Airs.

Which OS would my MBA handle, would Yosemite or Mavericks be manageable for it ?

  • Mine has the same specs as yours and is running Sierra fine and well. I'm still thinking about running High Sierra on it but I guess it can't handle it.... only 2gb of ram... – guest1 Nov 28 '17 at 20:48
  • Have you tried macOS High Sierra Patcher? – JMY1000 Nov 28 '17 at 22:12

It will take Sierra - which means unless you already have any earlier OS in your App Store purchase history, that's the only one you can get for it.

  • Yet isn't it possible to buy an earlier OS even though I have not downloaded it at the time ? example with snow leopard – totooooo Mar 28 '17 at 9:04

    Apple haven't sold an OS for money since Lion 10.7 [which is what that machine came with originally] & even then was really not much more than the cost of the CD it was supplied on. Everything since Mountain Lion 10.8 is supplied through the App Store only, & belongs to the Apple ID that 'bought' it through there [even though it didn't cost money]. The only way to get anything older than 'current' is to have already 'bought' it, so it's in your App Store purchase history. – Tetsujin Mar 28 '17 at 9:19
  • You said, "Apple haven't sold an OS for money since Lion 10.7" and that is not correct as Apple sold OS X 10.8 Mountain Lion, I know because I paid for it! OS X 10.9 Mavericks was the first free version of OS X. – user3439894 Apr 1 '17 at 15:12

    Close, even if no cigar - though that wasn't really the point I was trying to make. – Tetsujin Apr 1 '17 at 15:45
