Why Bootable Installer for Ventura Isn't working on Mac Studio M2 Max

For the record, I found the answer to my problem. As suspected Apple was blacklisting my installer via their over-the-top security with the newer OS/windows style software...

For the uninitiated, like me, here was the solution....

How to allow external startup drives on Apple Silicon Macs

   Shut down the Mac

   Press the power button and keep it pressed

   Let go when you see one or more drives and an Options section

   Select Options and click Continue

   When the Mac boots into Recovery Mode, select a Mac user you know the password for

   Log in as that user

   Ignore all of the options in the pop-up list and instead choose Startup Security Utility from the Utilities menu

   Click to select the Mac's internal drive and then click Unlock

   Follow the prompts concerning passwords, and select Security Policy

   In the Security Policy window that appears, click to select Reduced Security

   Then click OK

   Under the Recovery menu, choose Shut Down

I would have been great if the 'support techs' at Apple knew this or communicated it to during my hour long rant with them.

Clueless as usual but perhaps they did but just withheld it....

Who knows. Problem solved.
