If the ‘’ is not available, simply go to Other and click on any text editor present in the list.

7. Run Outlook for Windows on Your Mac

Another method is available to open MSG files on mac but this only works with intel macs. This is not for the latest M1 or M2. You can install Windows on your mac. Apple allows you to install Windows to be installed alongside macOS

To use Windows on your mac, restart your mac and press option key during startup to move from macOS to windows or vice-versa. After switching to windows, simply install outlook as like windows OS. Simply, open your msg file using outlook for windows.

If this doesn’t work, you can alternatively install windows on virtual machines like parallels and VMware Fusion. After doing this you won’t have to restart your system to switch to Windows.

However, this method is relatively expensive as you’ll have to purchase MS Windows and will have to go through technical steps—which is just too much work.
