High Sierra Storage Space Woes
High Sierra is an unforgivable mess when it comes to communicating free storage space.
What exactly are you meant to do when Boot Camp tells you that you need 39GB free space, Finder tell you that 126.14GB is available, and About This Mac tells you that 207.69GB is available?
Update 2018-04-10: Here’s what worked for me after a bit of digging on Stack Overflow:
sudo tmutil thinlocalsnapshots / 999999999999
I’m still left with Finder and About this Mac communicating storage values that are about 80GB apart.
