you have to get the mk3 i ran into this expierence, mk2 is not suppported os x & never will because of the mk3. huge latency issues. you can get it to work , but it sucks .

bluesdudeo, when you say mk2 are you referring to the 2408? If so then I don't think you will have any problems. I currently use a 2408 mk2 on a dual g4 with OS 10.3 and DP 4.6. The only issue was that the pci card must be the newer 424 version and not the 324. Using cuemix on the card we don't have any latency issues either. Been using this setup for over a year now and I am very happy with it. Hope this helps.

Edited to add: This is from the motu website-

The PCI-424 card included with 2408mk3 core systems is fully compatible with legacy MOTU interfaces originally designed for the PCI-324 card. Connect any MOTU PCI interface, including the 2408, 2408mkII, 1296, 1224, 24i, and 308. Mix and match new and legacy interfaces as you please.

yes to 2408 mark 2

I have the old pci card and I guess will need to get a new one also. yes? Do the new pci cards cost much ? and do motu sell them without all the other bits?
ps; THANKS for quick response.

Yes, the new pci card is a must. I was able to get one through my motu dealer without problems or having to buy anything else. I'm not sure but I think it was around $150 - $200 for the card. I can call my rep tomorrow and get a more accurate cost because I don't really remember the exact amount.

thanks jimi

Let me know about the card from your rep. There's no great rush though.

bluesdudeo, i heard from my dealer today, and he said you can purchase the card directly from Motu if you want. According to him, you don't have to jump through any hoops to get one either. I thought it was easy enough when we upgraded. As far as price, he seems to think it was more in the ballpark of $300.00. It's hard for me to remember because at the time, we purchased a newer dual g4 computer, the pci 424 card, a uad card, a powrecore card, and dp 4. If I can find the exact amount I will let you know. I think the best thing for you to do would be to contact Motu directly and they should be able to help you out. Good luck.

apple still sells pci G5's!!
