How do I update the operating system on my MacBook Pro

We can provide more specific advice if we know more about your computer model, year, and specifications. To get more information about your computer choose Apple menu  > 'About This Mac' in the upper left corner of any window, then "More Info..." or "System Report". Copy and paste the information here, but omit the serial number and UUIDs (if present). Please also include the year which may not be provided in this information. More about this in "About System Information [Profiler] on your Mac" - https://support.apple.com/HT203001

You can also use the computer information and the links below to yourself determine what is possible with your computer.

- This article also has links to system requirements for each OS version which you should check against your exact computer model. Note some of the model identifier articles are outdated. For any model produced in the last 5 years or so you should use the system requirements links for each OS version instead. This web site also has a reliable presentation of model and OS version compatibility: https://eshop.macsales.com/guides/Mac_OS_X_Compatibility

- Make sure you have more RAM than what is noted as "minimum" for any particular system or your computer may run slowly.

- You may find you need to use Safari to get links for High Sierra and later using the Mac App Store application to open a functioning page.

- Sierra, El Capitan, and Yosemite download as a .pkg. Click on this to have a converted version placed in your Applications folder as an "Install OS..." application. Run the installer and follow the directions.

- Upgrades may take some time (up to an hour or more) to install, with restarts and blank screens.

Back up your data in case something goes wrong --> Back up your Mac with Time Machine - https://support.apple.com/HT201250 or use a cloning tool.

Check if your old apps will still work with with the OS you want to install - https://roaringapps.com/apps This is particularly critical if you are upgrading to Catalina or newer, as older 32 bit apps will no longer work.

Your Mac is qualified to UPGRADE to as high as the current version of MacOS, Big Sur.

But I recommend you install 10.11 El Capitan as a waypoint first. This makes accessing later versions easier, should you choose to do so, and has far fewer restrictions than Big Sur. Links to obtain the software are in this article:

NB>> Be sure to make a backup before you begin -- there is no going back except to provide a BLANK disk to install the older version on later (that means erasing everything, so you need backup before you start).
