I have a 1st gen G5 1.6 with 1.25 GB ram.
The original disk is a 80Gb with 10.4.11 installed
The second disk is a 200GB Seagate that I just installed leopard and immediately upgraded to 10.5.1
I tried all the programs including Mail and Safari but found I had to re-install CS2. Since I only use Photoshop and Illustrator, that is all I installed. I also installed Little Snitch. (I have version 1.2.2)
Since then I have not been able to connect to the internet. All my accounts are set up properly and network diagnostics says that the ethernet connections are active.
Tiger still works fine. I must say that leopard has been a great disappointment to me.
Any suggestions/comments would be welcomed.
Women and cats will do as they please, and men and dogs should relax and get used to the idea.
It is strange how some people have had these issues. I thought Tiger was an awful OS for Intel Macs, but uusuable on G4's, it provided poor Java implementation and a lousy networking protocol with other DNS issues. Leopard fixed all the Java problems and my 24 inch iMac is much faster on my network.
I did have a few issues, but the tried and true test of removing third party extensions, startup items, etc., solved them. Little Snitch 1.2.2 is not Leopard compatible, 2.01 is the latest release and does apparently. There are a few Adobe products that are not happy with Leopard either, and CS2 installs its share of them. If found CS3 had to be reinstalled, and only after some Adobe updates, did it run properly under Leopard. I guess they are not updating CS2 to fix this.
Don't really know enough about how your internet access is setup to troubleshoot the problem. Dumping the old Little Snitch would probably be helpful. It is probably fighting with Leopards new firewall (under security), which lets you control network connections on an application by application basis.
Repairing permissions also took about an hour for me on the first run, so maybe try that as well.
Re: Internet broken in Leopard Works fine in Tiger
While not meaning to discount the problems the first two posters have had, one would have to be crazy to assume that Leopard had such fundamental problems as shipped.
The vast majority of the millions who have upgraded so far, including me, have experienced no problems and had quite the opposite experience -- faster/better/more productive with Leopard than with Tiger. This leads me to think that an installation problem, user error, or severe permissions issues is likely at fault.
