You could try & see if the Startup Manager can see the older OS X on the HDD:

You may try & see if by starting up in OS X Recovery, you can use the OS X Utilities

and select a different startup volume (such as existing pre El Capitan OS X) from there.


OS X: About OS X Recovery - Apple Support


If there isn't an undamaged or existing original OS X version installed or available on

the computer hard drive, the OS X Recovery may choose to try & get your original

computer OS X. The older system should be there; but it may be damaged.


If you have a time machine backup for the system previously running in the Mac before

this failed upgrade attempt, you could use that to attempt to restore the former OS X.

Various good ideas and suggestions are covered here:

Usually you can attempt a startup and force the mac to look for any OS X installed by

use of keyboard command shortcuts. Startup shortcuts and others, are available.

Hopefully these ideas may help. There are several possibilities so they may serve to

confuse; read round the issue/topic before attempting.


Good luck! 🙂

It says: OS X could not be installed on your computer. File system verify or repair failed. Quit the installer to restart your computer and try again.


I Can't do anything except restart and try again and it always fails.


The only prompts I have are the OS X Installer, file, edit, utilitipies, window. None of these do anything to help me or I just don't know how.


I Can't get back to the normal stem because it won't leave the error telling me it can't be installed. My coverage with Apple Care has expired also.


how do I fix this? Thanks!!
