When I performed a clean install of Big Sur on an old MacBook Air the installer never asked me my country, and has set that as Afghanistan. How can I correct that?
WHAT’S IN THE . DOCUMENTREVISIONS –V100 FOLDER?
You should see that hidden folder at the top level of most volumes containing edited documents. It contains saved versions of those docs, in a database which references old versions, probably using hard links. Alongside it you’ll also see the .Spotlight–V100 containing Spotlight indexes for that volume. The versions database is locked, inaccessible, and shouldn’t be disturbed, or you could lose all those old doc versions. There’s no point in copying it when you’re making a copy of a volume, as those versions won’t transfer to another volume.
HOW TO SEE HOW MUCH SPACE IS TAKEN BY SNAPSHOTS?
If you’re running Big Sur or earlier, you’ll need a third– party utility such as Carbon Copy Cloner. Disk Utility in Monterey can now tell you the size of individual snapshots, and how much space you should expect to reclaim if you were to delete them. To enable that, select a volume in Disk Utility and use the Show APFS Snapshots command in its View menu. Column headers have informative tooltips.
