install macOS Catalina for unsupported Mac

Your MacBook is not supported macOS Mojave and macOS Catalina versions, here is the instruction to install the latest macOS version on your Mac.

macOS Mojave and macOS Catalina come with a number of great features like Night Shift Mode, smarter Siri assistant and more.

By default, Apple only supports upgrading to macOS Mojave 10.14 or macOS Catalina 10.15 on the following models:

  • MacBook 2015 and later
  • MacBook Air 2012 and later
  • MacBook Pro 2012 and later
  • iMac2012 and later
  • iMac Pro 2017 and later (all models)
  • Mac Pro 2013 and later
  • Mac mini 2012 and late

In fact, if it’s not supported by Apple, your computer should be left in the current macOS version. But due to some reasons, you still want to upgrade your Mac to macOS Mojave 10.14 or macOS Catalina 10.15 version. With macOS Mojave Patcher and macOS Catalina Patcher, you can still upgrade your machines even when it’s no longer supported these two versions. 

However, you should note that macOS Mojave Patcher or macOS Catalina Patcher does not support all models. They just work with the following models:
