If you are lucky enough to be a fully fledged member of the OS X developer program, you’ll be pleased to hear that Apple have just released the OS X 10.9.4 BETA for download.
As the invite has only gone out to members of the AppleSeed members, and not the public BetaSeed lists, the download will only be available to developers.
Fingers are crossed for a BetaSeed release soon!
There’s currently little to no information about what the latest version includes, once more is known I will update this post accordingly.
