88GB Jump in Available Storage

[BayRunner]

Good evening all -

Installed Mojave on a MacBook Pro, Late 2013 model. Before the install I had about 12GB of free space. After the install I have 100GB of free space.

All my photos look to be here (I use to store on the MacBook but switched to iCloud about a month ago), and music is stored on a NAS.

Is there a way to compare a TimeMachine backup to my current folder structure to see what may be different? I can't see Apple making a macOS that streamlined!

Thanks
Kevin

I bet what happened was you had a bunch of space used by High Sierra's local snapshots, and the upgrade removed them. I noticed the same thing, although not as large as you.
