HOW TO INSTALL MONTEREY BETA 8 ON THREADRIPPER TRX40s
As you may have seen on OSX Discord server... last nights install of Monterey beta 8 didn't go to plan. It downloaded fine with j160 reboot, then when SBM=Disabled and Nvram reset, it wouldn't install beta 8 despite three re-download attempts too.
I didn't want to go the iMac17,1 way so I thought I would wait until a solution cropped up. Today, it did.
The new version of RestrictEvents Kext together with the latest Release candidate of OC 0.74 now works - and it won't upset your memory configuration (as set out by iGPU)
Here's the RestrictEvents kext, & download OC0.74: RestrictEvents.zip

This will negate the need to do anything like change your SMBIOS to iMac17,1 OR SBM=j160 ๐
Just install OC0.74, include the restrictEvents kext in your kext folder, then Propertree snapshot it into your config/EFI.
Reboot, it sees the update, installs, reboots just fine!
Job done.
