so i have a newer macbook pro and have been having major heat issues when running Rack even after implementing various osx performance suggestions (eGPU, lower frame rate, ect).
Rack can be a fairly graphics and processor intensive program which causes the macbook to run in turbo boost mode which creates a lot of heat pretty quickly. using free software to switch off turbo boost i’ve been able to keep the heat way down without using low resolution mode (which just kills the experience for me). downside is you wont get the performance boost that turbo boost provides so you may run into audio glitches on large patches. hope this helps some of the mac users around here.
