Hey there, how can I roll back to 10.5 without having to do a clean install? I ask because SL is truly an "under the hood" update, and until developers take advantage of the improvements, we won't see significant performance improvements. As of right now, plenty of stuff is broken. Cyberduck FTP doesn't work for me. Logitech Control center for my external keyboard/mouse doesn't work. And NTFS-3G is broken because it consumes 30% of CPU unless I eject all NFTS partitions, including the bootcamp partition. I thought I would be fine, I don't have any hacks/customization on my MBP, but those important tools don't work for me yet, so I want to wait a few weeks before I use SL. Thanks.
