Always loved Applejack BUT now it will not work with Snow Leopard that has been installed as a boot system on a SSD Expresscard on a MacBook Pro. (Holding down Command-s at the chime has no effect.)
Was GREAT up until 10.5 Version 1.5 Totally screwed up my 10.5 disk. Had to reinstall and lost tons of data.
This was once an indispensable utility for Macintosh computers followed closely by Disk Warrior. Unfortunately, the developer has opted to cease working on it. There will not be a certified version for Snow Leopard!
