In that case, I would suggest you backup your data, erase the drive, then reinstall from scratch.

Cannot Reinstall Os X El Capitan Update

Remember, this method is not the same as a clean install, and it only reinstalls the version of OS X that is currently running on the Mac (shown here with El Capitan), whereas Internet Recovery will reinstall the version of OS X that shipped with the Mac (in this case it would have been Yosemite) instead. Obviously the versions of OS X will. After reinstalling macOS in Internet Recovery Mode, use the Mac App Store’s Updates tab to upgrade your operating system to the most recent macOS version available. Some older Macs with OS X Snow Leopard may be able to use Internet Recovery Mode after installing OS X Lion or later, and a firmware update. Does anyone know what I can do to reinstall OS X El Capitan? Junkw macrumors 6502a. Jun 25, 2010 527 366 Haifa, Israel. Jan 5, 2020 #2 you booted with cmd-r. The date to use an older copy is Oct 23 or earlier, but not sure how you will be able reset it. Moitori (Tori Hernandez) November 17, 2019, 6:15am #3. You’re fine in understanding my issue. Now that the iMac won’t boot correctly back to Yosemite, I’m stuck.


Backup if possible before continuing.
