Hey, use this guide to manually uninstall AVID. Use when upgrading, or when you fucked up your install and want to start fresh:
Note: Projects, users, and media files will not be deleted in this process. However, it is always best practice to backup your media and projects through any Avid upgrade process.
1. Close out of all applications.
2. Unplug dongle from USB port
3. Manually uninstall the following files from the drive Avid was originally installed to.
Folder Name: /Library/Receipts/
*AvidApplications.pkg
*AvidUninstaller.pkg (either "Avid Media Composer" or "Avid Xpress Pro")
*AvidLibrary.pkg
*AvidSystem.pkg
*AvidLECodecs.pkg
*AvidPECodecs.pkg
*AvidDIORuntime.pkg
*AvidCoreRuntime.pkg
Folder Name: /Library/Application Support/Avid (you might need to install ProTools again)
*Delete Entire Folder
Folder Name: /Applications/
(either "Avid Media Composer" or "Avid Xpress Pro")
*Delete Entire Folder
Folder Name: /Applications/ExpressStripe
*Delete Entire Folder
Folder Name: /Applications/Utilities
*UpgradeDriver
*Avid Storage Manager
Folder Name: /System/Library/Extensions/
*ATTOExpressRAID_Enabler.kext
*ATTORAID_OS10.kext
*Avid_SCSI_RBC.kext
*Avid_SCSI.kext
4. Empty trash.
5. Reinstall the Media Composer or Xpress Pro upgrade. If an error message reappears, go through the list again making sure all files were removed.
6. Plug dongle back in, update dongle if you have not yet done so.
