I realize the ReadMe is not the clearest thing in the world for those of us who don't know all that much abotudirectories and contents and crap. I had to do a lot of research, but I figured it out and I'm here to give it to you clearly:
Step 1) After the torrent has completed its download, you'll recieve afolder filled with files with extensions ".r00", ".r01", ".r02", etc etc. Find the one ending in just ".rar" and double click on it. Proceed with the extraction. (Alternately, I believe extracting the".r00" one works as well).
Step 2) Mount the .ISO by double clicking. Most Macs should figure out what to do with it without trouble.
Step 3) Within the .ISO are two things: The Live .DMG, anda folder called "ArCADE". First, double-click the "ArCADE" folder.
Step 4) You'll see a few files. First, extract (double-click on) crack.zip and remember where it extracts to. Leave this windowopen.
Step 5) Go back to the .ISO folder, double-click the .DMG, and allow it to extract. Follow the installation instructions of the program (ie copy the folder to your hard drive).
Step 6) Goto the folder you just copied and open it up. Find the "Live" application icon, right click on it, and hit "Show Package Contents".
Step 7) Click "Contents" in the windows that just opened, thengo into the "MacOS" folder. You should see a little UNIX/Terminal app thing just labeled "Live".
Step 8) Go back to the folder from step 4 (the place that the crack extracted to) and replace theextracted crack (also just named "Live") with one in this MacOS folder.
Step 9) When it asks if you want to overwrite, hit "Replace".
Step 10) Close all useless windows and go back into the"ArCADE" folder from step 3 (or was it four...?)
Step 11) Double click on the weirdly named file. "Authorize81Mac" or whatever. This should run on its own, open Live, and then take its time loading...
