I'm not a techie, just a user and have a MacPro mid-2010 that is old but highly functional ... with a few glitches. Recently, when trying to launch Toast 14, I am getting an error message that is basically the same as what is being discussed here. I'd do a restore from Time Machine for the file(s) missing or incorrect if I could only remember the last time I used Toast 14 successfully! I've had it installed for years and this is the first time it's glitches out on me. My machine is running Sierra 10.12.6, and I'm doing doing a lot of System Updates because I don't want to lose the use of the older versions of software I'm currently still using. Never expected one of these 'older' software versions to suddenly glitch out. What could possibly have been installed on my system (without my knowing about it?) that could cause this disruption? Here's the pertinent info from Toast Titanium 14: Exception Type: EXCCRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXCCORPSE_NOTIFY Termination Reason: DYLD, [0x2] Wrong architecture Application Specific Information: dyld: launch, loading dependent libraries Dyld Error Message: Library not loaded: /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice Referenced from: /System/Library/Frameworks/CoreAudioKit.framework/Versions/A/CoreAudioKit Reason: no suitable image found.
