"2009 MacBook Pro won’t open: my 2009 MacBook Pro won’t open past the apple screen with a progress bar under it. The very last action I took on my Mac was installing El Capitan . I realize it’s been years since this happened, but I’m hoping someone can help please?"

Try these in the Order Shown:

• Safe Mode: Try logging in using Safe Mode (Hold down shift key upon boot). See if you can log in. Items only load as they do by default, while you are booted into Safe Mode. All caches are set aside. Go Here: Use safe mode to isolate issues with your Mac - Apple Support

• First Aid: Try Fixing the Disk: Boot into Recovery Mode (Hold Down: [command + R] upon boot : Select Disk Utilities > Click the First Aid button. Go Here: Repair a storage device in Disk Utility on Mac - Apple Support

• Reinstall the macOS - Nothing would be deleted. It's just that items that have become corrupted or deleted, would be placed back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support

• USB Bootable Installer: Are you concerned of losing data? If not, format the disk then install the macOS. Create a USB Bootable Installer for El Capitan. Then, install it. Go Here: How to create a bootable installer for macOS - Apple Support

You are welcome.

Well, reply back, if you do follow through with it, informing others of the output.

It’s worth a go.
