Apps · Moving apps to your fast drive
Can I keep using my Mac while an app is being moved?
Short answer: Yes — moves run in the background while you keep working. Just don't open the app that's being moved until it's finished.
Yes. Each move runs on its own and you can keep working in other apps while it does. Just leave the app being moved closed until it's finished.
A progress card keeps you posted, and if anything can't be completed it tells you why rather than failing quietly. For offloads, the window asks you to keep it open until the job finishes.
