I’ve solved this by running Unity as admin on my machine.
But now I have Unity+MonoDevelop on multiple university computers.
Letting students use them as admin is not an option.
Can somebody help?
You have to install Unity+MonoDevelop for all users and it will work fine. Try installing it by loging in with a non-admin account.
Thanks everyone,
This is Unity for Mac.
I will reinstall and see if there are options for all users.
