What is the latest system running on my Mac?

If you want to reset a Mac, prepare it for sale or simply install a new operating system, then the corresponding compatibility must be observed. In addition to the Mac OS, OS X or macOS with which the Apple computer was shipped, there is also the last available system for the computer. For an iMac from 2013, the latest operating system is e.g. B. macOS 10.15 Catalina. Models from 2014 get macOS 11.0 Big Sur as the latest system. But how do you find out quickly and easily without studying long compatibility lists? In this guide you will find two options;)

Find the most up-to-date, compatible operating system of the Mac via web tool

First, I'll show you a quick way to find the last OS compatible with the Mac. To do this, you first have to open the “About this Mac” overview via the Apple menu (top left on the menu bar). Then read out the serial number of the device in the "Overview" tab and add it appleserialnumberinfo.com a (text field at the top left). 

Hit enter and you'll find all sorts of information about your Apple computer. This includes technical data such as dimensions, CPU, RAM, etc. Under the heading "Operating System" you will find the system installed ex works for publication as well as the most recent system. However, the site is full of advertising, so the second option, the Mactracker app, might be more for you.

With the Apple Serial Number Info website you can find all possible technical data for your Mac with the serial number. Also the last compatible operating system.

Find the latest OS X / macOS for the Apple Mac via Mactracker

The app is a powerful tool for gathering information about Apple devices Mactracker. I introduced them to you in 2017 and pointed out their lexicon character. In the simple app you can see all possible devices from the first machines called “Apple” to the “Newton” to Mac, iMac and MacBook. 

Double click on the selected device and then on the "Software" tab in the window that opens. The operating system installed ex works is listed under “Original OS”. The most current system supported by the model is listed under “Maximum OS”. You can see which Mac model you have to look for in Apple menu -> About this Mac.

Note: If it says “Latest release of macOS” formatted in blue, it means that the selected Mac is compatible with the current operating system. At the moment it would be macOS 10.15 Catalina (as of 21.09.2020/11.0/11.0). When macOS XNUMX Big Sur is rolled out, the display changes on some models because they no longer work with the latest system.
