bootcamp not letting me resize partition
Hi,
I have a mac mini, (Mac mini (Late 2012)) and I am trying to install windows on it. I have high sierra installed and when I run Bootcamp I cannot resize the partition. I want to split it 50/50 but it first comes up with -8GB. If I click on the windows partition it jumps to 48GB but if I hit divide equally it goes back to -8gb. Does anyone have any ideas on how to fix this?
Thanks in advance.
Mac mini, macOS High Sierra (10.13.3)
