Hmm, unfortunately the site requires membership. And I am now remembering why I do not have membership.
It costs money.
I'm running student everything until I get out of school so unfortunately I do not have access to any of the autodesk downloads. I'll see if I can find your fixes anywhere else.

I have found at least one tutorial so far for that was written while using 5.0 which may be of some help. Here It Is.

Also I looked around the Digital tutors website and they have lots of content that is available for Maya 4.5 and up. If you cannot find something you are looking for and care to purchase from them why not contact them and see if they have anything for mac or from their older tutorials that are done in 5.0?
Here is an example of digital tutors. They have a bunch of free videos on using a lot of different tools that are good from 4.5-7 and such.


Still no luck on the mac patch for 5.0 anywhere free:<
