I think it is good that the OS is maturing. It looks like this is a lot of much needed polish as opposed to actually making the thing work right, which is what 10.2 was, and to a large extent 10.3 was. I'm happy to see such a so-called "minor" update. I mean, if only Microsoft would do incremental changes like this, their interface might not suck so bad. Instead they try to rewrite the damn thing every time out and it just leads to instability and problems. Anyway, I wouldn't hold my breath for free Safari 3.0. Safari 1.x died with Panther, and 2.0 will probably die with Tiger. You can, on the other hand, download webkit, which will be much fast (if a bit less stable) than 2.0
Be warned there is a bit of malware for OS X How to detect—and remove—the OSX.RSPlug.A Trojan Horse As always, with OS X, the user is the one to infect his/her machine.
Got it for 75$ from a university store. Completely screwed up my upgrade (Finder crashed permanently) and even an archive/install didn't help. I had to do a clean install. It seems to be running a bit slow on my iMac G5 despite my 2GB RAM. I thought it was supposed to be faster than Tiger! The Safari "snip to Dashboard" function is AMAZING!
2 things - the mail program is buggy and is apparently the main target of 10.5.1 update. This will only work if you read prior to installation - if you have Application Enhancer - found at the bottom of the System Prefs. window - a 3rd party app that is responsible for ClearDock, uninstall it before installing Leopard. If you don't, it will cause the Mac to get as far a a complete blue screen and nothing else, no progress, no way of ejecting the disc. Shutting down from source and starting up again still brings you back to the blue screen. If that should happen, just restart holding the C key and do an Archive & Install and all should be cool, but ClearDock doesn't work (yet) in Leopard.
If you google DivxNetworks folder and Leopard, you'll find a potential bug when upgrading that ruins it.
Really? I actually like Mail.app. It's very simple and easy to use. Many other Mac users use Entourage, Eudora, or Thunderbird.
