I need your help. I need to redo the DSDT.aml. I upgraded to a i7 3770 but the machine still thinks its i5 processor.


Please point me in the direction of how you compile the DSDT.aml.

the 14,4 smbios is extremely fast, tried switch to macmini6,2 very slow compared to 14,4.


Dont forget I'm still using Catalina!
