Leopard is certainly a first release. I installed on three machine different problem on all three including the one that I did a complete erase and install.
I have no alerts or system sounds. Zero. I checked and all of the alert folders in the library are totally empty. Weird.
On the macbook it deleted the Keychain. Gone. Poof. Had to start over and build a new one.
Those of you with iSubs for a speaker can put them on E-bay. Not recognized. Sorry. Stacks are just plain poorly done. I would rather have the option to go to a simple list view. The transparent menu bar doesn't bother me as I use a dark gray solid color desktop. If I did not it would bug me to no end. What is the purpose of it being transparent? At least make some of this goofy stuff an option. It can't be that hard.
Oddly before the release I thought I would like the 3-D dock. After using it however I would go back to the Tiger Dock in a flash. It provided more room for the icons and it was much easier to see what apps are open. The blue glow just is too subtle.
On the good side Aperture and other graphic heavy apps run noticeably faster. Quicklook is awesome. Safari has yet to crash.
I really hope 10.5.1 comes out real soon.
