I have a profire 2626 and if you have one you’ll know that M-Audio have been slow to update any drivers for this product. I think 10.8 is the only currently supported Mac OS for the profire 2626.
I’ve been reading some forums and have come across this suggestions. NB I haven tried it as I dont run 10.9x or above in my studio so I cant verify it works. But if you have already upgraded and cant get your profire 2626 to work with mavericks its worth a try before resigning the audio interface to the dustbin of history.
Here’s a POSSIBLE but HIGHLY INSECURE fix for those of you who MUST get their ProFire’s working. I DO NOT RECOMMEND this, but it seems to have worked for me.
Open Terminal (from /Applications/Utilities), and copy-paste this in:
sudo nvram boot-args=”kext-dev-mode=1″
Then provide your password, and then reboot the machine.
This will allow ANY kernel extension to run without code signing.
It appears the only problem with the drivers is that they aren’t code-signed, which became a requirement in Mavericks. This should be very easy for M-Audio to fix, but it appears they don’t care enough to do that. Good luck.
(Again, I don’t recommend this, as it is very unsafe. Bug M-Audio to release a compatible driver instead.)
It seems M-Audio have updated their drivers to 10.10 for the Profire series .
So after a long period of inaction they have EOL the profire but released some new drivers.
