[Solved] macOS Catalina - should eGPU Bootcampers update?
If Catalina breaks the bootcamp, can you simply reinstall Mojave to make eGPU work again? Do I have to reinstall Bootcamp Win 10 as well after downgrading from Catalina to Mojave?
Catalina can't break bootcamp unless it changes something in the firmware. Downgrading to an earlier macOS won't undo the firmware change.
