Hello, I have some questions about Yosemite. 1- What is the difference between dev version and public beta ? I read that the dev release have more frequent updates than the public beta. Is that right ? 2- Does a dev version weights more (like more debug code and logs) than the public beta ? Or exactly the same ? 3- What happended to both versions when final release will be out. Can I just update to stable version or need to reinstall ? 4- If I installed OSX server beta, what will happen when final release is out ? Because this one is not free I was wondering how it will work. Thanks !
