How to Install macOS Catalina on Unsupported Mac

From time to time Apple releases operating system updates to Apple Macs. But these updates are usually provided only for three years for any device after which your Apple product stops receiving updates and you are forced to buy new Apple products. This is why so many people end up having multiple Apple iPhones and Macbook Air.

Now that Apple has released a major update to macOS, some of your older Apple Macs might not be officially eligible to receive this update. You have no other choice but to buy the latest model of Apple Mac. But if you want to experiment with your older Mac, then you can try macOS Catalina Patcher.

macOS Catalina Patcher can update your old Mac to the latest version of macOS even if Apple says that your Mac has become too old to receive any update. With its help, you can enjoy macOS 10.15 Catalina – the latest OS from Apple named after the Santa Catalina Island, a rocky island in the Pacific ocean near California, US.
