How To Resume OS X El Capitan download after shutting down MacBook Air? I went to download the OS X El Capitan on my MacBook Air. Yesterday I've downloaded 2GB with 256kbps download speed. After downloading it all day, time to let the MacBook Air rest. This morning I went to open my MacBook Air, to the Apps Store, clicked the Free Upgrade. That time I was thinking: "Why is it not the resume button? Uh oh, something's not right." Typed in my password, download started, but from 0% Help? D:
You can't resume the download after a shutdown. But your MacBook Air doesn't need to "rest". So start the download again and don't shut down the MacBook until it's finished, even if it takes days.
