Mac OS X::This version of the beta will not work on Macintosh hardware with Power PC CPUs (see bug 587799)
It's funny because it actually works but it does have some issues with browsing but it still works. I'm guessing it is just a bug that they have yet to fix. Oh well I guess it is still a beta that still needs a lot of work but it is looking good.
As is always said when a post about beta software is posted we must warn about the risks of a beta:
Please note that this program is a pre-release beta version of a product and not completely tested to ensure its stability or reliability.
What is beta software?
The goal of a beta program is to collect information regarding the performance, quality, stability, and functionality of new products in order to iron out the bugs before they are released to the general public. If you choose to use a beta program, you use it at your own risk.
After an initial round of in-house testing, software publishers often release new programs to be tested by the public. These pre-release versions are called beta software, usually denoted by a "b" in the version number, e.g., Netscape Navigator 2.0b5. Since the publisher couldn't possibly test the software under all possible conditions, it is reasonable to expect that wider use of the software may uncover problems that were not discovered during in-house testing. The publisher expects to be notified when users find such problems so that the program can be fixed before its official release.
In general, you should expect to run into bugs whenever using any piece of beta software. These bugs may range in severity from minor features that don't work to problems that cause your computer to crash. You should decide whether the benefit of new features in a beta program outweighs the risk of program instability before choosing to use a piece of beta software. You should also be aware that UITS will not have thoroughly tested beta software, nor will the software be guaranteed by its maker, so you should not expect the same level of support as you would receive for an official release version of the program.
