This seems to be big news today. First, developers, don’t worry. People who weren’t developers but wanted to try out betas of OS X could do it anyway. This will be easier for them now. Second, this opening on Apple’s part isn’t a guarantee that they will do the same for OS X 10.10. Third, I understand that submitting clear and meaningful bug reports is not an easy task. But saying the general public cannot provide great feedback is a bit condescending. I’m happy to see Apple opening the process a bit more.
