Os x openzfs el capitan upgrade#
Catalina (macOS 10.15) required 18.5 GB of free space to upgrade from previous versions of macOS.Mojave (macOS 10.14) required 12.5 (El Capitan or later) to 18.5 GB in free space for Yosemite or older.High Sierra (macOS 10.13) required 14.3GB in free space to upgrade from previous versions.So we see the following progression of free space requirements: This is all great for the end users as problems with upgrades from previous versions seem to all but have disappeared.
The next few years saw new file systems, new apps, new ways of handling various objects on the file system, backing up snapshots to allow for easier recoverability, etc. The free space required to upgrade to El Capitan (Mac OS X 10.11) was 8.8 gigabytes as well, with 10GB being recommended. This was 2016 and the amount of free space required to do an upgrade would increase dramatically. Sierra (Mac OS X 10.12) had a minimum drive capacity of 8.8 GB but really needed more like 12 GB however there wasn’t a hard number sanity check that I personally ran into.

The amount of required free space had been growing steadily in the HFS+-era of file systems, but as more elements of iOS (like a modern file system) came to the Mac, and as the Mac transitioned to a fully 64-bit operating system, that number escalated and never returned now that the transition away from things like 32-bit apps and kexts is finished. The amount of free space required to upgrade a Mac has increased drastically in the run-up to and since the introduction of apfs-based snapshots in 2016.
