In [1]: from Foundation import *

In [2]: import os

In [3]: plist, format, error = NSPropertyListSerialization.propertyListFromData_mutabilityOption_format_errorDescription_(NSData.dataWithContentsOfMappedFile_(os.path.expanduser('~/Library/Preferences/com.apple.keychainsync.plist')), NSPropertyListImmutable, 0)

In [4]: plist
Out[4]: {KeychainSyncList = (); }

In [5]: data, error =  
NSPropertyListSerialization.dataFromPropertyList_format_errorDescription_(plist, NSPropertyListXMLFormat_v1_0)

In [6]: data.writeToFile_atomically_('foo.plist', False)
Out[6]: 1

In [7]: print file('foo.plist').read()
<?xml version="1.0" encoding="UTF-8"?>
