It's a Mac, so it's bound to have challenges.

Apple has at least three of their own file systems now.
They have HFS, and HFS+, but they've also added AFS
more recently. While GParted has support for HFS+
(from my Mac G4 box), when I attempted to change
a partition, the partition table got trashed. Rather
than being worried about merely writing to a partition,
I'd be more concerned about getting too adventurous with
GParted. I prepared in advance, and had a backup, so
"nobody got hurt".
