I too use MacOSX, and in the last release, added to a thread about some issues I was having with FTP.
I suspect it wasn't to do with MacOS, since it was with some cli FTP clients I used, including AFAIR the standard OSX and WinXP ftp. I did post a transcript, it was to do with the reporting of the sizes of the different partitions.
I'm not at home right now, but can redo the experiment and post.
The other thing I've noticed is the 'skin-returning-to-default' issue - this seems to happen to me only if I insert a DVD video, play it then use the IGR (or maybe eject, but my BIOS latest X2 with eject-fix, so I can't recall if this resets it).
No biggie, except to get to my skin, I think I had to do a hard reset (power off, then on).
Taxi!!!
