Hey guys
I wonder if you help me with my q
So I have iMac mid 2011 with Mac OS 10.14 high Sierra installed on it
And I have win 10 installed as well as a second system (70/30)
So the question is
If I want to update my high Sierra using Catalina patcher, would I have to erase everything on my SSD including my win 10? Or is it possible to save these 30% with win 10 and reinstall Mac OS only using 70% of SSD where my Mac OS now is? Thank you
 
You shouldn’t have to erase anything. You use the patched installer to upgrade your high Sierra install.
