    I recently bought used MacBook Pro that has ssd 256gb installed with OS X Sierra. I need to downgrade to El Capitan but my time machine backup that has El Capitan on it is almost a 1 TB so Time Machine says it can't restore because theres not enough room on the new drive.

    I also tried downloading El Capitan from App Store which I did, but when I try to install it says

    This copy of the “Install OS X” application is too old to be opened on this version of OS X.

    Need help!
