I decided to get a new 2020 Apple MacBook Laptop to do the local build instead of the hosted build. I am getting an error "Error Error extracting project.". I haven't used a Mac for a long long time. I see the Project.zip file on the Mac computer under Uploaded Projects, but the B4iProject folder is empty. I installed RAR Extractor, but it didn't make a difference. Am I missing a step or something?
