on about my mac under storage it shows 144gb of other files.
my concern is that when i run omnidisksweeper as root, it only shows about 188gb total and i have a 256gb hard drive.
249.77gb total after formatting according to about this mac.
if i add up all the totals from omnidisksweeper - ran as root - i get 139.8gb. + the 60gb of free space i get 199.8gb total.
i'm missing about 49gb from my drive?
