Apple Fix Audio Unit Bug in Mac OS X El Capitan 10.11.1

Back on October 9th we reported about the BETA for OS X 10.11.1 with a fix for Audio Unit validation! Today OS X 10.11.1 has been officially released and Apple tell us all is well.  

Following on from the “Oh no! Don’t upgrade to El Capitan unless you want to stop using many audio unit plugins”, to “El Capitan 10.11.1 BETA looks to be fixing it…” we’re happy to announce the latest update for public consumption is out. And better still it looks like most of the problems are no longer.

We’ve only done brief tests here, but the initial results are promising… Microsoft Office no longer crashes! Yes, we’re saved! OK. Only joking. We’re here to talk audio… so, yes, it looks like Apple has done some fixing under the hood and audio unit validation now works as expected. So, your Native Instruments, Arturia, etc. plug-ins should all be behaving themselves.

Some developers will likely issues some of their own patches and updates, so stay tuned to their communication channels.

Look how happy these NI plug-ins are in El Capitan OS X 10.11.1!
