I currently have version Mac El Capitan10.11.6 and need to upgrade to at least 10.13 High Sierra but have no updates available. How do I do this?
MacBook Pro 15″, OS X 10.11
The various ways of checking for software may only show updates to the current main system version you are running (e.g., 10.4.8 --> 10.4.11), not upgrades to a higher system version such as a jump from El Capitan (10.11) to Catalina (10.15). Note the difference between an update and an upgrade.
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). 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 Note some of the model identifier articles are outdated.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.

Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading

If you are considering upgrading to Catalina or Big Sur be warned they do not support 32bit apps.
Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,
some updates may be free, some may be paid. Use this app to discover which apps you have
are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see
if they are offering 64bit updates.
