macOS

Updating the operating system

Disclaimer

If you update or upgrade your operating system (OS) you do so on your own risk!

In general, there are many good reasons to update your OS. Some of the software tools or their functionality used in our tutorials will only work on more recent OS versions. Updating your OS will also ensure that you have the latest security updates installed and help prevent unauthorized access to your computer.

There a two main reasons that would prevent you from updating your OS:

1. Your hardware would not support the updated OS.
2. Some of your software you depend on might not work on a newer OS.

• Please upgrade to the latest version of macOS, Big Sur.

• Check your current version of macOS. If you do not have the latest version, follow the upgrade instructions on the Apple support page.

• If you cannot upgrade to the latest version, follow these instructions to find the system requirements and upgrade to latest versions available to you. If you need to maintain 32-bit compatibility for any of your software, then upgrade to no higher than macOS 10.14 Mojave.
