Back in August 2003, I bought a Sonnet G4 1400 MHz CPU Upgrade for my old G4 466 Digital Audio. And like form many other Sonnet customers, the System Profiler didn't recgonize my new CPU's clock settings. It just showed 0 MHz Power PC G4. This did absoultely no harm to my system -- until now. Yesterday I tried to run Final Cut Express Pro 2, but the program aborted the start up, claiming that FCE 2 will not run on a system with less than a 350 Mhz G4. The solution is quite simple:
Enter the Final Cut Express 2 package by control-clicking on it and selecting "Show package contents." Inside the /Contents folder, you will find the file info.plist. Open it with Textedit and you will see this:
...
...
<key>AELMinimumRAMSize</key>
<string>384</string>
<key>AELRequiredCPUType</key>
<string>G4</string>
<key>AELMinimumCPUSpeedSingle</key>
<string>350</string>
<key>AELRequiredIOPCIDevice</key>
<string>AGP</string>
...
...
Go to the line <key>AELMinimumCPUSpeedSingle<key> and replace the value 350 in the following line by 0. Save your file and exit TextEdit. FCE should now start up without any problems.
