I presently have Mac Osx 10.6.8. In order to update to Osx Mountain Lion's latest version, must I update to Mac Osx 10.7 and go through all of it subsequent versions prior? Also, is it advisable to save everything to an external hard drive or memory stick prior to upgrading?
MacBook Pro, Mac OS X (10.6.8)
