I have a macOS High Sierra OS on an iMac from 2015. What is the newest OS that I can put on this computer? My Safari isn't working for many websites anymore.
iMac 21.5″, macOS 10.13
Big Sur or Monterey, depending on which part of 2015; from early or late 2015, respectively.

Also check that your printer or scanner vendors offer drivers available for 64-bit, or that your printing and scanning gear supports AirPrint or TWAIN or such and does not need added drivers.
If you're using 32-bit apps such as Microsoft Office 2011 or earlier, that will need to be upgraded to at least Office 2016 (2021 is current perpetual license) or to Office 365 subscription, or an alternative.
You will want to find the 32-bit apps you're using with the Go64 tool, or similar. These tools will need an update, upgrade, replacement, or retirement.
