You can find a list of which Mac models can and cannot be upgraded with macOS Monterey on this page. If you are using such an older Mac and want to upgrade to, for example, macOS Monterey, but don’t see that option in System Preferences, this is the most likely reason why. This is because the requirements for the newer macOS releases go up and, those older machines can no longer keep up. With each year and each new major macOS release, Apple drops it support for more and more older Mac models. On the other hand, if you want to upgrade your Mac to a newer macOS, depending on your Mac’s model, this may not be possible. If you want to update the current version of your macOS to its latest version, there should be no reason why you cannot do that, so if you aren’t seeing any updates available, this could either mean that there’s some issue that’s preventing you from getting the latest update or that you already have the latest update installed. For instance, upgrading from macOS Big Sur to macOS Monterey. Upgrading your Mac, on the other hand, means installing a newer macOS release. After the update, you’d still be using Big Sur. For example, if your Mac is running on macOS Big Sur 11.2, you can update Big Sur to its latest current version (as of now, that version is Big Sur 11.6.3).

Updating your Mac means that you install a newer version of its current macOS. If you are using an older Mac, this could also be why no updates are available.īefore we get any further into this post, we must first clarify something: there is a difference between updating and upgrading your Mac. No updates being available on your Mac is an issue that can be related to problems with your Internet connection, a recent macOS upgrade, or a temporary bug.
