How can I update my last version 10.12 to 10.13 or latest?

Hi,

if your MacBook pro is introduced in mid 2010 or later you can install High Sierra (10.13).

You can see the requirements on the upgrade websites from Apple: How to upgrade to macOS High Sierra - Apple Support

If it is supported just follow theses steps: How to upgrade to macOS High Sierra - Apple Support

If you want to upgrade to the latest version (Catalina/10.15), look here: How to upgrade to macOS Catalina - Apple Support

Greetings

The model year of your mac will determine what OS you can upgrade to.

When clicking on the links use the Safari browser, Firefox does not work for this.

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

and do not use any other devices that share the same internet connection.

If you are considering upgrading to Catalina be warned that it does 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/. Once the list has been created you can then

contact the developers of the apps to see if they provide 64bit updates.
