Very easy way to reinstall Mac if you are thinking about selling your computer or simply need to install a fresh copy OS X El Capitan follow the tutorial to.

Dear all,

I’m trying to prepare a 2009 MacBook Pro (my first Mac) for a friend who would take it for himself since neither AppleStore nor Brightstar wanted to recycle it.

I followed all steps here https://support.apple.com/it-it/HT201065 even if it can only support El Capitan 10.11.6.

After erasing the disk, I selected reinstall Mac OS X. It duly downloaded it (~40mins), then rebooted once, white screen with grey Apple appeared, charging line as well, “20 minutes remaining” followed then… big X logo of Mac OS X appeared with the writing, paraphrased from Italian:

Install Os El Capitan

”impossible to install Mac OS X. No valid package found. Contact your vendor. Exit installation to restart and try again”

I tried again a few times, with no improvement.

Any idea what could have happened and what I may do to solve this?

The Mac worked beautifully until I started following those instructions and tried to reinstall the OS to make it usable for my friend… it would be a pity if, after all these years of service, it would have to end like this.

Any way to bring it back to factory or to make macOS install work?
