As Mountain Lion becomes available for purchase people will be upgrading their systems. Some people are early adopters and just can’t wait to get their hands on the newest system. I would offer you a word of warning however. Native Instruments has reported some compatibility issues. I would recommend that one waits until all these issues have been ironed out. If however you are happy to go test things
out, then NI have released some Beta Drivers
for those experiencing issues.
In the NI newsletter they say the follow:-
Due to USB audio driver issues present in recent versions of OSX, some NI products will experience a degraded audio signal when used with OS X 10.8 “Mountain Lion” on any Apple hardware. The same issue occurs with the current-generation MacBooks under 10.7 using USB 3.0. Specifically, the following NI products are affected:
AUDIO 2 DJ / AUDIO 4 DJ / AUDIO 8 DJ
AUDIO KONTROL 1
GUITAR RIG MOBILE
GUITAR RIG SESSION
KORE 1
RIG KONTROL 2 / RIG KONTROL 3
TRAKTOR AUDIO 2
TRAKTOR KONTROL S4
If anyone has any advice to offer other users in relation to this, then please help out by commenting below. Also not forgetting that NI have also just released a Traktor Update 2.5.1 – this can be downloaded via your Service Centre.
Traktor Tips 
The issue I have with the S4 is that ever since I’ve upgraded to 10.8.3. I can no longer S4 nor NS6 as controller. As for the S4, it could recognise the device but cannot be used as a controller, I’ve tried different patches, none of them seems to work. Upgraded Pro 2 to 2.6. didn’t work either.
on Mac os x Mountain lion
for omni control controler what driver?
Where can I download a fresh copy of Service Center for 10.8? The downloads available on the NI Website only offer up to 10.7. Help?
Beta drivers worked for me, thanks! When could we expect a full driver update through the service centre?
Good question – I am sure it is something of a priority for NI – maybe their forums wold be a good place to ask? http://www.native-instruments.com/forum/
it doesn’t work for me!!! i have 2 mac(mac mini and macbook) and they doesn’t work with audio8dj
That really sucks – there are many links on NI forum in relation to this sort of stuff – here is a link to a search for mountain lion – http://www.native-instruments.com/forum/search.php?searchid=7531176
Beta Drives was a big help for me
Excellent thanks Ravi!
this sucks. Not totally unexpected, but a bummer just the same. Growing pains.
I have been getting some reports of people having no issues with their upgrade – just be weary – maybe do a time machine back up before upgrading – then you could always roll back!
