However, many users MacBook reason doesn't seem weighty. The counterargument is that some computers, for some unknown reason, were selected while their more powerful contemporaries (e.g. MacBook Pro) mysteriously ended up behind.

According to one version, Apple is thus increasing the requirements in order to stimulate the purchase of new devices. There are no other compelling circumstances that lead to the appearance of unsupported computers. Often this version turns out to be justified - with the help of several tweaks and additions, a tool from dosdude 1 called macOS Sierra Patcher solves the problem of “incompatibility” of many computers with this version of the operating system. In this guide, we will tell you how to install macOS 10.12 Sierra on older versions that, according to the manufacturer, are incompatible with this operating system.

Today's list of devices supporting macOS 10.12 Sierra includes:
