Since I bought my MacBook, which is 111.47 gigs, it has consistently showed available space as if it were approximately 1/2 of the size
In September, I could count up 51 gigs of data, & I had 3+ gigs available. Verified my count with Disk Inventory counted 51 gigs, & similar result with the utility they used at the Apple Store. (51x2+3x2=108G)
Today:
Disk Inventory shows 50.3 G, & I have 4.09 G available,
(so not precisely 1/2 but close: 50.3x2+4.09x2=108.78)
What Size shows 52.3G: (52.3x2+4.09x2=112.78 G)
I've checked for partitions.
Doing a full backup to my external via SuperDuper it is copying around 100 gigs (not done yet so can't see), as if I have more to backup than 51 gigs.
Apple Store genius bar said it's a software problem with the operating system & I have to wipe completely & reinstall (hence the full bootable backup - just in case). Thought I would check here for any other options. It is still under warranty.
