when I connect my pd-150 on my Imac 10.3.9 it freezes allready at the beginning.

When it's not connected (firewire)...it just starts. No problems with connecting to my powerbook g4...only with the Imac an that's never happened before also....

Any suggestions welcome!

What are the specs of the iMac?  Is it Intel-based?

The specs of the mac with the problem is Imac, 16 ghz, powerpc 1,5 gb ddr sdram

anyone???

What version of QT Sjon? Also, you don't say what version of the Avid software.....

<p></p> avid 4.3.5 qt 7.4.5. (just upgraded....might that be the problem)?

Could be, yes. I would roll back to the approved version as a first troubleshooting step. May not solve anything but it will eliminate a variable.

what version of qt is compatible again and how can I downgrade?

Check out the OSX Cheat Sheet announcement on the top of the Forum page for the OSX, Xpress Pro and QT version matrix.

where can I get QT 6.5(1)...? Is this stil available...did a search, but nothing...

thanks blkdg! you're the best.

One more to go: I dropped QT in the trash and tried to install qt 651...then I get the message:

not possible, there is a newer qt allready installed....

how does this work????

There are third party apps that will let you uninstall QT but the easiest way is  to just do an archive and install of your OS and then upgrade only as far a 6.5.1.

how can i archive and install os? sounds more difficult than uninstall qt??

No, it's not actually. It is very simple.

Just put your Panther install disc in and boot from it. In the install options window, choose "Archive and install". Also choose to preserve User and Network Data. A new copy of the OS will be installed leaving your applications and user data untouched. You  will, however, have to reinstall the Avid software after doing this.
