A survey of support for APFS, HFS+, FAT and ExFAT, NTFS, ZFS, Linux file systems, and MacFUSE with its potential for file systems running in user-space.
file system
How APFS is the first Mac native file system to have true inodes and inode numbers. What they are, and how you can use them in volume groups and different types of file link.
When the numbers simply don’t add up. How some extended attributes may be included in quoted file sizes, but others are ignored, and Sequoia hasn’t really changed this since Classic Mac OS of 25 years ago.
How can you access files on a NAS connected directly to an Apple silicon Mac, or those saved to external storage using Ext4 or similar?
A brief start with MFS for 400 KB floppies, followed by HFS intended for the first hard disks, upgraded to HFS+ in 1988, and followed in 2017 by APFS for all the OSes.
How to tell whether someone has been eating the (APFS) porridge on one of your disks, using Get Info and DiskUtility’s First Aid. And a surprise hidden volume from 3 years ago.
APFS or HFS+? Which can Time Machine back up to? What about hard disks? Which format for use on PCs? And which are supported by Disk Utility now?
Apparently Sequoia includes user space file system support, as now used for the MSDOS file system in macOS. Is it ready to use yet?
Documentation changed to match the bug, seldom-used features that no longer work, and malware protection that devoured parts of Xcode.
Union mounts let you merge the contents of two volumes without copying any files. Do they work as expected in Sonoma’s APFS, though?
