upgrading an older iMac

The macOS version you can upgrade to depends on the year your Mac was released.

Click the Apple menu () at the top of your screen and choose About This Mac.

✅ Check the compatibility of your Mac hardware with newer versions of macOS software:

➡️ macOS 10.13 High Sierra is compatible with the Macs listed here

➡️ macOS 10.14 Mojave is compatible with the Macs listed here

➡️ macOS 10.15 Catalina is compatible with the Macs listed here

➡️ macOS 11 Big Sur is compatible with the Macs listed here

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

Catalina and above won't run 32-bit software and split the functions of iTunes up; if you choose one of them, use Go64 as well.
