I posted this earlier and received no replies. Since then I have discovered this Beta forum.
I am looking to install Mac Alpha tonight and would like detailed instructions on how to go about it, including:
- If I download the the Alpha via my L4 purchase, is this the latest release?
- How else could I go about downloading it
- What do I do once it is downloaded?
- Are there any other tips or instructions?
The reason I ask these questions is, like others, I have been having problems with the installer. My Fan is going a million miles an hour and my RAM is at full use - I have also noticed that nothing is being downloaded when all this is going on!
I'm not what I would call a techno-geek and am unfamiliar with how to find out what is happening on my Mac - I just turn it on and go! 
Many Thanks
