  • It can run some later versions of OS X but not all features of new versions of OS X are supported.

    Found the following info about MacBookPro3,1: "This system can run the last version of OS X 10.8 "Mountain Lion" and OS X 10.9 "Mavericks" although it does not support the AirDrop, AirPlay Mirroring, or Power Nap features. It also supports the last version of OS X 10.10 "Yosemite" and OS X 10.11 "El Capitan," but no advanced features are supported. It is not supported booting into 64-bit mode when running Mac OS X 10.6 "Snow Leopard," either. It does support "OpenCL" and Grand Central Dispatch, though. It is not capable of running macOS Sierra (10.12) or subsequent versions of the macOS at all."

    MacBookPro3,1 was introduced June 5, 2007 and discontinued on February 26, 2008. Apple states that El Capitan's requirements include MacBook Pro (mid/late 2007 or newer).

    Try opening the App Store app on your Mac and searching for "OS X" or "MacOS". If OS 10.11 is supported by your Mac, it should appear in the App Store app. If your Mac is also supported by OS 10.12 (Sierra), OS 10.12 will appear instead of OS 10.11 if OS 10.7 or later is already installed.
