ObjectSupportLib is a baddie, has been a baddie for some time now (since 8.0 ?) and will cause strange behavior if not outright crashy behavior... it is apparently being installed on Macs by 3rd party software installers these days, causing much grief...
ObjectSupportLib file should be removed from any new Mac with extreme prejudice.
OLDER MacOS'es and systems that use older MacOS'es need it.
