I hate saying this because I am also on a mac. Need to jump back on a PC with higher base core speeds. I have other reasons that will lead to my PC migration and it's not about gaming. You can build a PC with 2 SSDs, 8 core overclocked Intel running at 4GHz plus, M2 storage, a higher performing video card, 32GB ram, for under 2K. Where a mac trash can will run 4-5K and the iMac Pro will be over 10K. Both with slower core speeds.
Are you bouncing everything to audio?
