You'll see that I've only used 131.22GB from a 500GB HD, but it's not letting me select a larger partition size. Now, I just updated the High Sierra and it was letting me choose the size before. When I'm in bootcamp, this is what I get:

This video explains it. It's due to TimeMachine using an older file format and once you disable it, it will remedy the error and you can proceed as intended.

Apparently I'm not allowed to "update this content" and edit this post. The max is 63GB from Disk Utility (unshaded). From Bootcamp, the max is 43GB. SMC and NVRAM Reset did not resolve.


What's up with the 8GB free??


I'd like to allocate 100GB to Windows and leave the rest for my Mac...
