I had purchased a bundle deal for some of your games few months back, now when I try to install them again, they are not running, I have an mackbook laptop, and I think it happened because I did an software update, is there any solution for that
Was the bundle you originally downloaded for macOS? Or Windows? (you should see 'macOS' somewhere in the file names) If so, I haven't heard of that problem before and will need to check whether Unity builds differently for OS X now.
