I’m not sure how old our 9″ Air is. Maybe 2009 or 2010 (update: mid 2011). It has been a terrific machine, The 2008 MacBook Air was the ultimate personal computer. Newer Macs are all regressions.
Alas, Sierra did it in. I just updated from El Capitan and it is too darn slow. SPODs are ugly things. I’m glad I waited to the last minute.
I’ll try a few things, maybe drop back to El Cap, but a new Mac is coming. Shame there is nothing I like. If I had to buy today I’d get another Air…
