If you are having issues with your Macbook or iMac, or you just want to maintain a current operating system, we strongly advise keeping your Macbook's MacOS version up to date to the latest release version. Having an up-to-date MacOS version incorporates all of the fixes and new features that Apple provides to their products, and it is likely to solve a majority of software-related issues you may be experiencing.

How to View Currently Installed MacOS Version

1. In the upper-left corner of the screen, click on the Apple icon.

2. In the drop down menu that appears, click on "About This Mac".

3. In the About This Mac window that appears, the MacOS name and version number is in the center of that window. 

How to Update MacOS on your Macbook or iMac

1. Go to the Dock and click on the icon for System Preferences

2. In the System Preferences Menu, click on "Software Updates"

3. In the Software Updates menu, you should see a button offering to begin downloading the latest version of MacOS, or a button offering to install the version of MacOS that your system has already downloaded. Either of these are acceptable, and you should press the button to proceed with updating.

If your system says that your system is fully updated to the latest version and no buttons appear, then your system is already fully updated. No further work needs to be done until the next MacOS version releases.

4. Follow the instructions provided in order to install the latest version of MacOS. No changes need to be made, just proceed with the steps as instructed.

5. Once the MacOS update is downloaded and ready to install, you will be prompted to restart your machine. Restart your machine manually, or allow the machine to restart automatically after a timer, in order to install the update.

6. Wait until your system is finished installing. This may take less than a few minutes or over an hour, depending on the size of the update.

Do not turn off your device manually during installation, even if it seems frozen! Doing so may corrupt the sensitive installation and render your computer unusable. Let the computer do what it needs to automatically.

7. Once your Macbook reboots and loads to the sign-in screen, the update is complete.

A Note About Updating MacOS on Older Devices

Apple drops support for older versions of their devices, citing hardware and compatibility issues. Therefore, not all Macbooks and iMacs are able to update to the latest version of MacOS that Apple releases. As such, if your older device is reporting that it is fully updated on a MacOS version that you know is out of date, know that this may be intentional and would indicate that Apple no longer supports that device type. 

If you are in need of the latest version of MacOS but your device does not support that latest version, the only option is to replace the device with a newer one that does support the necessary version of MacOS.
