upgrading 10.12.6 to 10.13.6 without clean install

App store does not have any legacy method for downloading system updates.

I need to upgrade a late 2009 iMac running 10.12.6 to 10.13.6 without wiping disk for a clean install. Is this possible?

If so, where to find the software (since Apple doesn't care to provide any)?


Thanks for vectors!

iMac, macOS 10.12

Back up your data, check the application compatibility table, click here, and then on the download link for it.
