After installing the TC TDM plug-ins and updating to Mac OS X 10.4.9 on my Intel Mac, Pro Tools suddenly crashes. What's going on?
This issue occurs if you updated to Mac OS X 10.4.9 via Apple's Software Update, rather than by downloading and installing the 10.4.9 Combo Updater.
This issue affects only Intel based Mac systems and is related to the iLok copy-protection USB key.
How to fix it: Download and install the 10.4.9 Combo Updater on top of your existing installation.
