this is a really terrible idea.
- derefr 3y agoMacs already do this for other things, e.g. downloading updates. The feature is internally called "DarkWake" and exposed to the user as "Power Nap" (https://support.apple.com/en-ca/guide/mac-help/mh40773/mac https://support.apple.com/en-ca/guide/mac-help/mh40773/mac). I would note that there's definitely a reason that macOS hasn't attached anti-malware scanning (or similar things, e.g. Spotlight indexing) to DarkWake wakeups, though. The other things DarkWake does are all IO-bound (network activity, disk activity) with a bounded workload size (the size of the update); while anti-malware scans would be CPU-bound (lots of hashing for signature checking) with an unbounded workload size (however much stuff you have on your HD.) Doing IO-bound activity, just on some efficiency cores, in their base power state, for a minute or two, is fine; even if the laptop is in your bag, it won't heat up, any more than your phone heats up in your pocket. Doing "real work" in the same situation is not fine.
