We don't get too many issues on the installer on the Mac failing. In this episode, the error is:
Errors: Could not Authorize User. System Error Installation cannot continue.
In this case, the solution is to create a root user account and install Maya using that account instead of your default main account with Administrator privileges. The root user account will be labelled "Other" when you logout of the main account.
Thanks to Tom Salciccia for sharing this tip with the community.
