I recently downloaded the Adobe Reader for Palm OS (for Mac) to my MacBook running 10.4.8.
As soon as I launched the app, it closed again, and the console.log (/Applications » Utilities » Console.app) gave this error (line breaks added):
2007-02-02 21:10:18.327 Finder[375] CFLog (0):I opened the Applications folder in Finder, then selected the Adobe Reader for Palm OS app, control-clicked and chose Show Package Contents from the pop-up menu. From there, I went to the Contents folder and opened the Info.plist file in Property List Editor (the default app for .plist files, if you have the Developer Tools installed).
CFPropertyListCreateFromXMLData(): plist parse failed; the data is not proper UTF-8.
The file name for this data could be:
Contents/Info.plist -- file://localhost/Applications/Adobe%20Reader%20for%20Palm%20OS.app/
The parser will retry as in 10.2, but the problem should be corrected in the plist.
