Original Question:
I posted this on another forum here, but it may be more suitable here:
I have both High Sierra and Catalina installed, on 2 respective SSD's. in the same system. However, I get vastly different Geekbench 4 scores for each.
High Sierra Single Core score = 3413
High Sierra Multi Core score = 16183
Catalina Single Core score = 1601
Catalina Multi Core score = 9489
Installed using Unibeast and Multibeast.
As you can see this is a huge difference. Any help would be appreciated.
