For those of you who have Leopard and would like to run Avid MC, here are the steps I took to run a successfull install:

1. Update Leopard to 10.5.2 (including Quicktime)

2. Install Media Composer 2.8

3. Recieved digIO.kext error

4. Restarted Avid and was prompted to Pace website

5. Installed Interlok extention for Mac OS v5.6.1

6. Recieved error "app core midi server quit caused by Direct IO plug-in"

7. Went to library>audio>mididrivers and dumped everything

8. Went to system>library>extentions and copied interlok extentions to folder

9. Restarted computer and launched Avid

10. Began editing with no problems

Hope this helps!  Enjoy!

System Specs:

20” iMac 2.16GHz Intel Core 2 Duo processor

ATI Radeon X1600

2 Gig RAM

500 Gig G-Tech Quad Interface Drive

This will only work if you do not have the Nvidea 8800 installed.

Which version of quicktime are you on?

Quick Time 7.4.5

Will this also work with a new macpro 8 core with the stock ati card?

yes.

I can confirm the above steps on the new 2008 8-core systems - with one additional finding:

If when you get the "app core midi server quit caused by Direct IO plug-in" you click to "Ignore" and then "Exit to Finder" on subsequent startups it works without having to remove the MIDI Drivers from the Library folder.

Hi Nicky, thanks for the guide. I Didn't understand step 8, could you elaborate? As a result I still can't get Avid to run. It bounces up and down on the dock for a bit and then says 'this application has quit unexpectedly', in that useful mac way.

 Fiendish,

In step 5, you installed the interlok extentions, which by default goes to the desktop.  In step 8, you will simply copy those interlok files you downloaded and paste those files in system>library>extentions. 

What kind of system do you have?  You may not have the right video card.  Also, which versions of MC, Quicktime, and Leopard are you using? 

Hi! thanks for quick response. Interestingly, the Pace installer didn't have any errors. It installed a kext called PACESupportFamily, which is active, and left one called ATINDRV on the desktop which i put in extensions, then restarted. MC just bounces then unxexpectedly quits.

This is with MC 2.8, Leopard 10.5.2 and QT 7.2.1

It may be the graphics card.  I see that you're using the NVIDIA Quadro 3500.  The "ATINDRV" controls the framebuffer for all ATi graphics cards.  Since you are not using an ATi card, this will not help you.  I would try to update your driver at nVidia's website.  Also, if that doesn't work, consider running a dual boot with Tiger or Windows on it.

Keep us posted, and good luck!

thanks for that. That ATI must've been from when I binned all the ATI extensions that were installed. What's confusing me is that unlike for you, the PACE installer seemed to work without error, and left nothing on my desktop...

As to drivers, you can't get Mac drivers from nVidia themselves.

Will MC run on Leopard soon or will it take several months?

Now, you know that would be speculatin'....

I wonder if you could help me with this.  I'm new to Macs.  Bought a Mac Pro with OS X 10.5.3 and Avid Media Composer 2.8.0.  I was able to install it, but I have no menu bar in Avid!  Also, my timeline disappeared and I can't get it back!  (I think if I have a menu bar, I should be able to get my timeline back.)  Any thoughts?

Thank you!
