Repairing permissions has a long history in Mac OS X. The permissions concerned have changed over the years, and it’s no longer what it once was.
Disk Utility
How to protect collections of files using different encryption passwords, and making most efficient use of storage space.
Disk errors threaten your data: how to detect them, how to use First Aid in Disk Utility, how to use fsck, and what to do with the disk afterward.
Disk Utility version 22.6 in Ventura 13.4 finally tackles bugs running First Aid on APFS volumes. Has it finally solved them?
The update to macOS Ventura 13.4 is relatively small, and brings several improvements and fixes, including the following […]
How can you have two volumes in the same APFS container with identical names? How does macOS handle the conflicts?
After studying thousand of log entries in less than 2 seconds, this is how macOS updates its values for purgeable and available space. But who uses them?
Deleting two large files from a volume triggered the updating of figures for purgeable and available space within 9 seconds. Yet 6 minutes later, the Finder didn’t show those updated figures.
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?
Good space management doesn’t bring new emoji, but it makes a big difference when the Finder doesn’t give completely inaccurate figures for Available space. A practical demonstration of its gross errors.
