I just use VI and MIR PRO 3D in Logic as well as other AU like Kontakt, this save CPU
I am working on a 100 tracks project with no problem on my MacBook Pro 2019 64 GB
I am experimenting Dolby 7.4.1 at the moment
Just need to reboot when you start working in Logic, this to clear all memory used by other apps
