If your 27" iMac has a hardware model year of

  • Late 2015 – macOS 12 (Monterey) is the end of the line. (Earlier models cannot update as far as Monterey.)
  • 2017 – macOS 13 (Ventura) is the end of the line
  • 2019 – macOS 15 (Sequoia) is the end of the line
  • 2020 – macOS 26 (Tahoe) is the end of the line


If, by any chance, you have a 2017 iMac Pro (gray/black case, Intel Xeon processor), macOS 15 (Sequoia) would be the end of the line.


How to download and install macOS - Apple Support


Unless your 27" iMac is running Sequoia or Tahoe, it will not receive the latest versions of Safari (Safari 27.*). If you cannot update that iMac to one of those versions of macOS, you may want to install a third-party Web browser such as Firefox whose current version will run on your iMac.

Hi Sherry,


To be able to install macOS Ventura 13, you would need an iMac model 2017 or later. You can check the year of your Mac in  > About This Mac.
