To find out which version of macOS your computer can run, start by identifying your Mac’s model. Then, compare that information to the options available on Apple’s official website. Once you know what your Mac supports, you’re ready to begin the installation process.

Next, use your serial number to check your warranty and model details:
- Open your web browser and go to Apple’s Check Coverage page.
- Enter your serial number in the space provided and click “Continue.”
- Review the details on the page to find out your specific Mac model.
Once you know your model, compare the model number with the list of supported macOS versions on Apple’s website. Make sure your Mac meets the minimum system requirements for the operating system you plan to install. If necessary, expand the details by clicking “Show more” on Apple’s support pages to see additional specifications about your Mac.
Knowing your exact Mac model and compatibility helps ensure you download the correct macOS installer and get your new operating system up and running smoothly.
