El Capitan Boot Screen Compatible Video Cards For Mac Pro 31

by

I have a Mac Pro 1,1 up and running on OS X El Capitan 10.11.6. Video card is a ATI Radeon HD5770. I've just installed PT 12.8 and all new codecs and drivers on this fresh SSD. I've also tried PT 12.8 on the same machine running Yosemite (OS X 10.10) on another SSD and video engine doesn't work. Video engine won't load after trying to turn it on in playback engine. Same machine running Yosemite (OS X 10.10) and PT 12.7.1 and video Engine works fine.

Supercars unlimited If you have a mac pro, it means buying a better graphics card than the one that comes with the mac pro, that way your graphics card wil have full support on el capitan and it will run smooth. If you have a macbook, you can't upgrade because the graphics card is soldered to the motherboard.

Is the video Engine vastly different in PT 12.8??? I've even left it over night trying to load the video engine and still won't load. Can anyone help?

Your problem is probably due to you're running an OSX version that is not supported in the least for a MacPro 1,1. The latest supported with the efi update is OSX 10.7.5 aka Lion.

I spoke to Daniel Lovell (Fantastic guy!) from Avid in person at SMPTE Sydney and he mentioned trying a couple of things; 'Go to /Users/Shared Delete the AvidVideoEngine folder Then try and launch the Video Engine again from within Pro Tools: Go to Setup->Playback Engine Check Enable Video Engine Click OK' 'The Pro Tools Video Engine does not launch, or Pro Tools hangs after creating a video track. This may be caused by having a '/' character in the name of a mounted storage volume. To resolve the issue, rename the volume and remove the '/' I also found this; 'Try this: 1. Launch Pro Tools 2. Go to Setup/Playback Engine 3. Choose different hardware in pop-up menu (for example from HDX to ProTools aggregate I/O - it is important to make a change) 4. Uncheck all checkboxes in Playback Engine window.

Enable Video Engine 6. Click OK (Video Engine should launch properly now) 7.

Go to Setup/Playback Engine again 8. Choose desired hardware and other options. If you'll find Video Engine disabled turn it on again. 'Try holding the 'n' key as soon as the Pro Tools splash screen appears during launch. Check your current Playback Engine and make sure the proper device is selected.'

'his can occur when importing video, opening a session with video or launching Pro Tools from a session that has video. This can be caused by a conflict with drives or media mounted on the system or a corrupt Workspace.wksp file. Start by deleting the Workspace.wksp file: Navigate to /Users/Shared and move the Workspace.wksp file to the trash.
