- simonh 5y agoBut since I only use Mac desktops.....
- jb1991 5y agoI guess a UPS powerbackup would be useful. Laptops basically have built-in UPS which is perhaps why Apple has gone in that direction. I wonder if their high-end desktops with Apple Silicon will do something different there.
- freemint 5y agoAn UPS won't help though unless you program your Mac to check the UPS status and flush accordingly.
- jb1991 5y agoI'm not entirely sure how a UPS works with a computer, nor exactly how this flushing works, but doesn't a UPS run for awhile in the event of a power disruption, certainly more than the several seconds delay with this flushing?
- acdha 5y agoThat’s been built in to macOS since the 2000s - there’s a standard USB protocol which most UPS vendors support.
- kevincox 5y agoUnless of course your kernel panics. (Although there may still be a best-effort flush here, so it probably depends on how exactly it dies)
