I just had to do it. I upgraded to Snow leopard and it is not seek the PCIe 424. In fact it hangs the system up for about 4 - 5 mins. Tried reinstalling driver and still no go. MOTU claims that the PCIe will work with Snow Leopard. Ironically my Mbox 2 will work after I remove the PCIe drivers.....Anyone else having this issue?

I am having the exact same issue. I have reloaded the driver three times and it's not being recognized. It's 7:50pm East Coast so their support line is not open so I will have to wait until Monday. Dam.... and I was hoping this was going to be so easy! When I display the the hardware it tells me there is no driver installed. Not sure where to go from here? My system hangs as well on the boot.

2 x 2.66 GHz Quad-Core Intel Zeon
16 GB Memory
MOTU 24 I/O
PCIe 424 interface
Logic Pro 8 (still works fine)

Delete MotuTigerDriver.kext from /System/Library/Extensions and it should solve this issue.

THANK YOU! That did the trick and everything is working great! You are best.

Cheers,

Worked here to. Thank you very much........

Vinnyl, you saved my computer from going out the window! After I upgraded to SL, the PCI card was not found and I installed the new driver. On reboot, my desktop was frozen-- no dock, couldn't click on my drives (but my mouse moved). I finally had to boot in 64-bit mode (holding down the 6 and 4), to get my computer working, and I could at least get on the internet, where I found your suggestion. Now the 2408 is recognized. Can't wait to see what other adventures lie ahead.

I'm wondering if the MotuTigerDriver.kext might adversely affect the Leopard 10.5s systems as well. Is it needed to run Leopard 10.5s?

I've been having the same trouble, but I had actually thrown that file out twice, and yet it was back again! I guess it gets reinstalled with the installer. I used the installer to uninstall everything several times, then tried to install only exactly what I needed with the custom install. It STILL put the Tiger file back in there, but I didn't see it.

Ok, now I've got to restart and see if that fixes mine.

[edit: yes, it fixed it. The installer keeps putting the Tiger kext back into the Extensions folder, so every time you re-install your drivers, it gets "broken" again. Just remove the Tiger kext. It's all working now. /edit]

Thank goodness for MOTUNATION!
I had the same problem and trashing the kext was the trick.
I really hope MOTU is posting this fix somewhere on their website.
That wouldn't be too much to ask for would it?

I'm having the same problem, I have a 2408 mk2 with the PCIe 424 card, but I don't seem to have that MotuTiger.kext to delete. I upgraded to the newest Motu drivers and to OS 10.6.2, but when I try to boot my computer it hangs up after the finder loads and I can't do anything. Anyone have any other ideas of why could be wrong?
