Need to Keep computer active for long virus scans
I used to be able to keep my MacBook Pro running for hours without interjection by using the Caffeine.app. Since purchasing the MacBook Air, I am unable to activate the software, probably because the app is no longer free, and the company ignores my launching an older version of the software.
How to I adjust the time used to keep the screen awake so that it doesn't abort my virus scans?
MacBook Air, macOS 13.5
