Not with any previous version of MacOS can work upgrade to the desired version. So, if your MacBook is running version MacOS Snow Leopard (10.6.6.8) and your MacBook will earn with the MacOS Sierra version, to start, update to the MacOS X El Capitan version.
As an example, the MacOS Sierra version is taken. Other copies are looking for and "put" in the same way. Your actions are as follows.
