Reverting from QT 7.5.5 to QT 7.5

Hi Everyone,

Since this problem seems to continue biting people in the…you know, I thought it might be helpful to provide a new post complete with steps and links.

Enjoy,

Reverting from QT 7.5.5 to QT 7.5

The following procedures are officially unsupported by Apple, Inc. and Boris FX – Media 100. However, if you wish to backup from QT 7.5.5 to QT 7.5, this is the only way to do it as of this writing.

You cannot simply downgrade with the QT 7.5 installer, even after deleting the Receipt files from your Library folder.
You can, however, downgrade with a shareware application called “Pacifist”. It is designed to do unsupported installs and anecdotal reports suggest that it works fine with the QuickTime 7.5 Installer.

EXTREMELY IMPORTANT!!!:
Be sure to download the correct QT 7.5 Installer. Running an installer that does not match your Mac OS will result in a Mac that won’t boot!

You can download a QT 7.5 Installer for Leopard here: https://www.apple.com/support/downloads/quicktime75forleopard.html
You can download a QT 7.5 Installer for Tiger here: https://www.apple.com/support/downloads/quicktime75fortiger.html
You can download a QT 7.5 Installer for Panther here: https://www.apple.com/support/downloads/quicktime75forpanther.html

1- Download the appropriate QT 7.5 Installer – See alert above
• Mount the downloaded Disk Image to reveal the installer package inside

2 – Download and Install Pacifist
• Find it here: https://www.charlessoft.com/Pacifist.dmg
• Mount the Pacifist Disk Image
• Copy the Pacifist folder to your Applications folder

3 – Remove the receipts for QuickTime 7.5 and 7.5.5
• Go to MacHD > Library > Receipts and delete the packages (.pkg) for QuickTime 7.5 and 7.5.5

4 – Use Pacifist to bring you back to QT 7.5
• Launch the Pacifist app
• Click the “Open Package…” button and point Pacifist to the QT 7.5 Installer Package (inside the disk image that you downloaded from Apple)
• Highlight (single-click) the “Contents of QuickTime75…” package in the bottom half of the Pacifist user interface
• Click the Install icon at the top of the Pacifist UI
• When asked what sort of operation you’d like to do, choose to “update”
• When asked about replacing files, check the checkbox to remember decision and then click the “replace” button
• When it’s done, restart the Mac and you should now be back to QT 7.5

And as an additional tip for those who (like me) cannot remember these OSX codenames:

OSX 10.3.x=Panther
OSX 10.4.x=Tiger
OSX 10.5.x=Lepoard

Wick – others – Ran into this issue yesterday. But before I revert –

I basically work by importing legacy Media 100 videos into Compressor (I also use Final Cut Studio)

Anyone aware whether reverting to 7.5 will cause an issue with FCP ? (In case any of you are running both sets of software)

Thanks
Dennis Dean
