hi guys,

after an update to mountain lion my setup doesn't work. i work with vdj and use the two cdj 400 as midi controller.

does anybody has an solution for my problem? somebody of the vdj forum told me that there is a problem with the software for the cdj.

does anybody else has this problem?

do i have to downgrade my os x?

hi gavin

somebody told me that there is a problem with the driver software of the cdj 400s'.

i've seen that the current issue appears on 7th july 2011. do i have to download an install something other.

it's very important for me to run the system because i'm dependent on cdj 400 combined with the mac.

i hope you have the solution ;)

@Jack > Have you received any updated information from VDJ?

Please ensure you have the CDJs on the latest firmware available here:

after my require to pioneer they put a statemant to the support category of the cdj 400. now there is standing that the update for iOS will be released on the beginning of november. (see below)

so it seems that vdj isn't the reason for not running.



Verification of OS X Mountain Lion v10.8 standard driver software is planned in beginning of November, 2012.
