I bought my MacBook Air 7,2 13″ in mid-2015. It is the best computer I’ve ever owned. No contest.

Today, while playing with etreCheck (great donationware app), I discovered my Mac had a manual. Turns out every Mac has a manual — available for download at support.apple.com/en_US/manuals.

Actually, mine has two manuals, a very brief “Quick Start” PDF and a longer “Essentials” PDF. (I didn’t see an iBooks version).

Scanning Essentials I relearned the Split Screen feature. Which I’d forgotten about. Handy feature, if a bit obscure.

Some poor writer put these manuals together. They’re really well done and worth reading, especially if you’ve been using a Mac for eons.
