Reinstalling El Capitan on MacBook Pro Mid 2009. Thread starter Kaminogi; Start date May 28, 2016; K. Kaminogi New member. Joined May 28, 2016 Messages 2 Reaction. Apr 06, 2021 Reinstall macOS. Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions. Follow these guidelines during installation: If the installer asks to unlock your disk, enter the password you use to log in to your Mac. If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.

Once you’ve done that, here’s how to install, reinstall, or upgrade to El Capitan, step by step: Boot from your Recovery HD partition by restarting your Mac while holding down the Command+R keys. The OS X Utilities. Select Reinstall OS X, and click Continue. The OS X El Capitan splash screen. FIX This Copy of the Install OS X El Capitan Application Can’t be Verified. If the issue is with your Computer or a Laptop you should try using Restoro which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption.

I was trying to do a clean install of the OS since I had to give the laptop to my mother, so I rebooted the MacBook and held Cmd+R. Apparently everything was fine, I cleaned the disk and was reinstalling the OS but it was taking so much time (27hrs estimated and no sign that the process was progressing) that I quit the installation and tried the initialize disk once again, but failed at that. So I rebooted the whole system and now it seems that Cmd+R doesn't work anymore. All I can do is holding Option to select the drive, which doesn't lead me to anything. The system tries to boot but the screen with the Apple and the loading bar doesn't go away. I've thought to make a bootable USB but I don't really understand how through Windows.
Any ideas?
It really doesn't need to be El Capitan, I just want the Macbook to work.

Upgrade from previous versions to OS X 10.11 (El Capitan)

  1. From the Apple menu, select App Store....
  2. When the App Store opens, search for and download El Capitan. If you don't already have an Apple ID, you'll need to create one. You can monitor the download process in the 'Purchased' section of the App Store.
  3. Once the download is complete, the installer should automatically open.

    If it doesn't, or you don't want to complete the installation at this time, you can come back later and double-click Install OS X El Capitan in your Applications folder.

    Within the installer, click Continue, agree to the license agreement, and then choose the disk where you want to install El Capitan.

    After you begin the installation, your computer may need to restart more than once before finishing, and then you may be asked to enter basic information.

  4. From the Apple menu, select App Store..., and then install any available updates.
