Ensure Sufficient Free Space before Upgrading to Ventura

Originally published at: Ensure Sufficient Free Space before Upgrading to Ventura - TidBITS

After hearing about Ventura upgrade problems from a reader, Adam Engst did some research to determine that you should try to have at least 37 GB free before upgrading to Ventura. And how you determine that 37 GB might matter.

The free-space problems you saw in trying to upgrade to Ventura probably explains why my MacBookAir 2017 with a 128 Gig hard drive is not able to upgrade to Ventura. I had to delete a lot of file and some apps to be able to upgrade it to Big Sur (and later Monterey). I wonder if Apple really has a reliable way to assess how much free space is needed, and why they offered a 128 Gig hard drive in 2017?

“The devil is in the snapshots!”

Reminds me of this, from the New Yorker a few years ago. Very funny.

So, if you have that 37 GB to install the system, does that mean that once it’s installed, you have no room to actually do anything?

No, because Ventura is probably roughly the same size as Monterey and you’ll delete the 12 GB installer when you’re done. You should end up with about the same amount of space free at the end—it’s just working space during the install.
