Your device is ready to embrace Mac OS X El Capitan 10.11 after going through the steps mentioned earlier. Now it's time for some real action. Step 1 Visit the official Mac App Store and search for Mac OS X El Capitan. Your search result would Stake you to the El Capitan page. Download: OS X El Capitan This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder.
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:
Reinstall Mac Os X Yosemite
”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.
Installing Mac Os X El Capitan
Any way to bring it back to factory or to make macOS install work?
Thank you
MacBook Pro 15″, OS X 10.11
