Check compatibility
The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.
If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it may say that it's not compatible with this device or it's too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:
- macOS Catalina 10.15 hardware requirements
- macOS Mojave 10.14 hardware requirements
- macOS High Sierra 10.13 hardware requirements
- macOS Sierra 10.12 hardware requirements
- OS X El Capitan 10.11 hardware requirements
- OS X Yosemite 10.10 hardware requirements
Download macOS using Safari on your Mac

- macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite or Mavericks
- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks or Mountain Lion

Safari will download the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It will install an app named Install [Version Name]. Open that app from your Applications folder to start installing the operating system.

- OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion or Snow Leopard

I’m sorry to hear about the issue you are having with what I imagine you expected to be a straightforward install; that’s always frustrating. I’m sure we can help you out, but before we dive in it may be good to establish what we are working with:
1. Were you able to successfully copy your files to the external hard drive as you noted? Do you have any other full or incremental backups of your system from prior to the install, like in Time Machine?
2. What are you seeing when you try to reinstall from Recovery? Is it giving you an error, or is it just hanging/failing? If you are seeing an error, what does it say specifically?
3. Similarly, what are you seeing when you try to verify/repair the disk? Is it saying that the disk is fine, is it finding repairable errors, or is it failing because it cannot repair the disk?
Again, I’m sorry to hear that this happened, but we should be able to get you pointed on the right track.
