I recently had to re-install the original OS from the discs that came with my MacBook Pro. This installed Snow Leopard and software updates have taken it to 10.6.8. However it refuses to upgrade to Lion, Mountain Lion or Mavericks. (I've tried them all a few times). I have repaired permissions and checked the HD is OK (which it is).

Check compatibility

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation.

To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.
