27' L2013 iMac OCLP version, to find

Yesterday when I triggered the on/off button; I received a start-up error note.

I tried several things:

° Screamed at it, performed like Batman,

° Drank multiple espressos, 2 wodka rb:

° Then I started threatening to throw him out of the window at night,

° Ending with some multiple keyboard combos..

And ended up with the fresh installation of macOS X

Now I tried updating the system with the help of OCLP, but I can't find the right version for this OS.

After installation OCLP, I keep getting the error:

u have os x 10.9.5, program needs 10.10 or higher.
