I experienced the following error when attempting to create a C++ project with the Unreal Engine 4.22 on a Mac running 10.14.3:
An error occurred while trying to generate project files.

- Open Terminal found in Finder > Applications > Utilities.
- In Terminal, paste the following: defaults write com.apple.finder AppleShowAllFiles YES.
- Press return.
- Hold the ‘Option/alt’ key, then right click on the Finder icon in the dock and click Relaunch.
- Set permissions for .config directory to Read and Write for the current user and/or admins.
I also experienced the same error when setting up and Source Control within the project. Now creating a C++ project and setting up a Source Control was done without issue.
I was wondering if there was a better way to resolve this and I hope this helps anyone that is having the same issue.
