A few months ago Skype has been release the new version 7.56(776) for Mac OS after issuing we got problem with some MacBook running on OS version lower then 10.9 we need to upgrading our MacOS X to 10.9 or above for installing the newest version of Skype 7.56(776), But some old generation of MacBook can’t upgrading to that version because new version of Mac OS X can’t support with some old generation of MacBook I think hardware capacity of old generation of MacBook is to small it is digital to run the latest of Mac OS X.
