Before you update, read this!

I just wanted to save lots of people... umm... lots of time.

Most of this issues people are experiencing in going from Tiger to Leopard are resulting from leaving 3rd party tweak / modification utilities installed while atempting to perform an upgrade/archive & install.

In order to have a smooth install, remove all your tweak/mod programs before you attempt to install Leopard. That will save tons of trouble and frustration.

One final word. I'm probably going to be flamed for saying this... using tweak / modification tools on a Mac seems to cause more problems than it's worth. Consider using a vanilla interface and you'll have far fewer problems. I guess i've noticed this applies really to any OS, even Vista/XP.

Personally, I just did a manual backup and a clean Leopard install. With the amount of program compatibility issues it currently has, I'd rather start from a clean slate.

Oddly enough, I've had 0 issues. I'm on the newer 15.4" Macbook Pro (2.2ghz, 2gb RAM). No sluggish expose, spaces, etc.

I upgraded first and Leopard was a tad buggy for my liking (things that had nothing to do with 3rd party software). So, since I had a backup of my Tiger install I did an erase & install. I was more than impressed with setup assistant's migration of all my previous settings, itunes & iphoto ratings, etc that I'll do it again in the future. Now Leopard runs smooth and buy free. I love it.
