Default what\'s the deal with the mbox 2 pro?

Hi, I currently own a mac pro 2.66ghz with 3 gbs of ram, Protools 7.3.1cs2, OSX 10.8 and I have been having issues with 6086 errors and buffer underflows. For your information I followed all the recommendations made by digi. Right now I have the mbox 2 pro hooked up to the back firewire port and doesn't run off the AC power supply. On the front firewire 400 port I have two lacie drives that are daisy chained, from which I run all my projects from. Nothing runs on the FW800 ports. My Protools is set to 1024 buffer, 4 processors, 90 percent CPU and the ignore errors is enabled. I think that's all you need to know.

So basically, but rarely I get these error messages popping out of the blue during playback. There's no reason to since my sessions are very light. I heard that the mac pro's firewire ports were all on the same bus. Could that be the issue? Digidesign could you confirm this? Should I buy a seperate firewire PCI card? Or should I run my sessions from a seperate internal SATA hard drive and use my FW drives as backups?

I have to admit that I have struggled far too much to try to solve this. I want this problem to be fixed, or at least I would like a solution.

Also, another issue I encountered. I also run Windows XP through bootcamp and have done some tests. I realised that Protools in XP is more performant than in OSX! I simply stacked a bunch of plugins and noticed that XP could handle more without struggling. What is the deal with that? In addition XP seems more responsive? Is there a reason?

Cheers,

Fred

I'm assuming you mean OS X 10.4.8?

Well with some extensive testing. Windows XP running on my Mac Pro is pretty rock solid with Protools. Is there an explanation for that? Plus I can load up quite a few more plugins...

Default Re: what\'s the deal with the mbox 2 pro?

Ok here's an update! Digidesign take note. So the windows side of my mac works fine as it should. On the OSX side I did something that triggered something in protools. I think it can only be 2 things : 1) a full disk warrior checkup of my boot drive OR (2) I have a spare MOTU 828 mk2 card and decided to hookup the spdif out of the unit to the spdif in of the mbox 2 pro and let it run as the Clock Source, therefore disabling the internal clock of the mbox.

I don't know which did it, and I hope I'm not being too premature about my discovery, but everything seems to be rocking for the moment. Actually as I'm typing and surfing the net I have a pretty big session running in loops with 32 audio tracks packed with plugins with CPU meter half full and so far no hitches in the system. I can add 30 compressorbanks in one shot during playback and protools won't give me error messages anymore. So could it be that the internal clock of the mbox is buggy with OSX?

Please take note of this. FYI my mbox2 pro is hooked to the back port, and my 2 firewire drives are daisy chained to the front FW400 port.

Thanks, in hopes to finding a solution...

Fred

Here's another issue I've been having lately with protools. In the past week I've had 3 kernel panics while using protools. Here's the log :
