Hi,
Another thing you can try is to reduce the vCPU count, so go from the currently assigned 2 vCPU's to 1 vCPU.
Honestly it should not make much of a difference with your intel i7 CPU, but it might.
There's other questions too, like is your VM busy doing something, or is the CPU in the guest idle?
How much RAM has your mac?
