Free Space Required for Modern macOS Upgrades

Charles Edge:

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. This was 2016 and the amount of free space required to do an upgrade would increase dramatically.


The net result is that when doing the last few upgrades, they have required 12+GB for the installer itself (which can be run from a USB drive) and up to 44GB for the installer to do the work it needs to do, so a total of up to about 56GB. Therefore, scoping policies to run an updater without causing undo issues to end users it’s entirely appropriate to make sure they have the amounts of free space indicated per version. Given that drives can be a terabyte in size, this doesn’t seem wildly inappropriate; however, many organizations still buy devices with 256GB drives (thus going from an eighth in the 64GB drive era to a quarter of common drive space required to be free for certain upgrades on smaller drives today).

These days I find that I want about 150 GB for a test partition that will include macOS, Xcode, and enough space to clone my Git repo and run the tests.


Update (2022-11-09): Nick Heer:

Users are disrespected by increasing and surprising bloat in applications. For work, I need to run the Microsoft OneDrive client on one of my Macs, and I was surprised to see that it recently crossed the 1 GB threshold. This is a file syncing utility.
