I recently bought PT 12.5.2 and loaded it onto my MacBook that already had El Capitan (10.11.5) running.
I feel like throwing both the laptop and the iLok from the 25th floor balcony and buying Cubase instead.
I can't bounce mixes to disc or even play through an entire 3-minute song without error AAE-9073 coming up.
It is fine for editing short sections and setting up the mix, but last night it took 37 attempts to bounce to disc a rough mix of a 4-minute song before I was lucky enough to get through an entire bounce without crashing. Very embarrassing when a client has to hang around for nearly an hour when the job should have taken 4 minutes.
I am so angry that AVID was selling ProTools to Mac Users in 2016. There is no point advising people after the event that there are problems with 10.11.4 and beyond because when you buy a Mac you can't buy previous versions of the OS. I was told in the Apple Store that I can't load an earlier version of El Capitan or even load Yosemite onto my MacBook. I'm pretty pissed at Apple too.
I've been trying to find out if PT 12.6 will have a fix for this problem (and other stability issues), but the promo material is unclear.
Does anyone know if the El Capitan problems will be fixed with PT12.6?
Advice from AVID would be very welcome. The silence is deafening.
