These are the two framework class methods that were called:
+ (void)initialize {
if (self == [PFUIElement class]) {
// Accessibility API bug workaround support.
isFixedMenuActionBug = ([self
QSWStandardizedOperatingSystemVersion] >= versionMenuActionBugFixed);
....
+ (unsigned long)QSWStandardizedOperatingSystemVersion { // private
// Returns the system version as an unsigned long integer in BCD format in
the form "0x00MMmmbb", where MM is the major release, mm is the minor release,
and bb is the bugfix release, padded with leading zeroes as needed to ensure
two-digit fields. Obtains the system version from the string in the
ProductVersion entry in the SystemVersion.plist file at
/System/Library/CoreServices/SystemVersion.plist, which may be in the format
"10.8.5" or "10.9". Returns 0 in the event of an error such as failure to find
the SystemVersion.plist file.
// Use the %x or %X string format specifiers with +[NSString
stringWithFormat:] in NSLog calls. This code adapted from Steve Christensen
http://lists.apple.com/archives/carbon-dev/2005/Oct/msg00788.html.

[NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSSystemDomainMask,

stringByAppendingPathComponent:@"CoreServices/SystemVersion.plist"];
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) return 0;
NSData *plistXML = [[NSFileManager defaultManager]
contentsAtPath:plistPath];
NSDictionary *contents = (NSDictionary *)[NSPropertyListSerialization
propertyListFromData:plistXML

errorDescription:&errorDesc];
if (!contents) return 0;

NSArray *versionComponentStrings = [versionString
