APFS

Customising metadata display in the Finder

Where to look for file metadata in the Finder, and how you can customise it, in spite of its apparent confusion. And how APFS takes care of extended attributes for you.

Last Week on My Mac: Should we be worried about data integrity?

Last Week on My Mac: When the numbers don’t add up

One volume has 60 GB of purgeable space, giving 295 GB available; the other has only 15 GB purgeable, so 250 GB available. How can they be in the same container?
