Changes in Time Machine reflect continuing development of this Mac-only feature, backtracking on using FSEvents, and making backups more complete.
Time Machine backups made by Catalina are not compatible with earlier versions of macOS such as Mojave. Here’s how they have changed.
It’s time to replace Occam’s Razor with a more appropriate principle: if you’ve found one bug, don’t stop until you have dug deeper and found the others.
Over the night the clocks went back, a Time Machine backup failed. Was this the result of a time error from that change?
Snapshots are one of the crown jewels of APFS, and very powerful. Why then has Apple made them almost impossible to use?
