Hello, I have been following this thread but never saw a resolution, has anybody found a fix for this error? Is it an update to the latest squid or was it a problem on Apples side? I have been searching for an answer but have not found one. I am using: Squid Cache: Version 2.5.STABLE11 Here is the error: 007-03-19 11:17:33.011 Software Update[186] loader:didFailWithError:NSError "XML parser error: Encountered unexpected EOF Old-style plist parser error: Malformed data byte group at line 1; invalid hex " Domain=SUCatalogLoader Code=0 UserInfo={ NSLocalizedDescription = "XML parser error:\n\tEncountered unexpected EOF\nOld-style plist parser error:\n\tMalformed data byte group at line 1; invalid hex\n"; NSURL = http://swscan.apple.com/content/catalogs/index-1.sucatalog; } 2007-03-19 13:49:29.953 Software Update[201] loader:didFailWithError:NSError "XML parser error: Encountered unexpected EOF Old-style plist parser error: Malformed data byte group at line 1; invalid hex " Domain=SUCatalogLoader Code=0 UserInfo={ NSLocalizedDescription = "XML parser error:\n\tEncountered unexpected EOF\nOld-style plist parser error:\n\tMalformed data byte group at line 1; invalid hex\n"; NSURL = http://swscan.apple.com/content/catalogs/index-1.sucatalog; } ### MRJPlugin: getPluginBundle() here. ### ### MRJPlugin: CFBundleGetBundleWithIdentifier() succeeded. ### ### MRJPlugin: CFURLGetFSRef() succeeded. ### 2007-03-19 13:58:11.977 DiskImages UI Agent[209] Could not find image named 'background'. 2007-03-19 14:24:28.542 Software Update[230] loader:didFailWithError:NSError "XML parser error: Encountered unexpected EOF Old-style plist parser error: Malformed data byte group at line 1; invalid hex " Domain=SUCatalogLoader Code=0 UserInfo={ NSLocalizedDescription = "XML parser error:\n\tEncountered unexpected EOF\nOld-style plist parser error:\n\tMalformed data byte group at line 1; invalid hex\n"; NSURL = http://swscan.apple.com/content/catalogs/index-1.sucatalog; } Any help or direction would be greatly appreciated, Jon
