Have you tried running dirac from a windows computer? The only issue I've had so far is that the newer versions take a very long time to sync the profile to the receiver, but eventually everything is ok.
I would suggest against using AccuEQ if Dirac does not work; IMO AccuEQ has never been all that great.
With my DRX3.4 I found AccuEQ to be decent but not as good as Dirac....
On the other hand it allowed me to tune levels & distances for all speakers prior to running Dirac, and led I think to a smoother Dirac experience.
My first Dirac setup was using the phone app, and that was quick and painless.
My second and subsequent tries were using the PC app, and although the interface is far richer, and has a heck of a lot more options, it also took a heck of a lot longer, and was more complicated.
No complaints - I am very happy with the results, but if someone is looking for a quick way to get going (and leave to slower more detailed/complicated methods to a weekend when they have the house to themselves!) - then the mobile app and/or AccuEQ are not a bad way to go!
P.S. - on my first attempt, I had no errors... this may have been due to running AccuEQ first, which meant the gain/levels were already set before heading into Dirac.
Later efforts using Dirac PC version, did experience the errors (associated with optimising the gain/levels and ensuring sufficient headroom between signal and noise)
