MP 1,1-5,1 MP5.1: Catalina strange behaviour detecting CPU - PRE Big Sur tweak?

[unpapapro]

I have a MP5.1 2012, with dual-X5690, and strangely, when on Catalina, the system is tagging it as a 3.5MGhz and not 3.46... in the machdep though, it shows correctly...

This behaviour changed in the last update, because in 10.15.5, it was ok...

"someone" told me that Apple decided to change some details in the Catalina distro, so any of the CPU that load like a recent supported Mac would be supported with the Big Sur distro... do someone knows about this?

That’s because you activated HWAccel by injecting the iMac Pro board ID

Nothing need to be checked. That's normal, macOS just round it up to 3.5GHz for displaying, purely cosmetic.

May be just you didn't notice that. It's always like this if you enable full HWAccel via OpenCore.
