I have downloaded 365, but the error message says needs Mac OS 14.0 or later.

Hi,

In this case, you can use this version of office below if it is 365

To install Microsoft 365 on your Mac running macOS Catalina 10.15.7, you should be aware that the latest updates for Office for Mac require macOS Big Sur (11.0) or later. Since you are currently on Catalina, you will not be able to install the latest version of Microsoft 365 that requires macOS 14.0 or later.

Here are your options:

  1. Upgrade your macOS: Consider upgrading your Mac to macOS Big Sur (11.0) or later. This will allow you to install the latest version of Microsoft 365.
  2. Install an older version: If upgrading is not an option, you may need to look for an older version of Microsoft 365 that is compatible with macOS Catalina 10.15.7. However, keep in mind that using an older version may not provide you with the latest features and security updates.

Ensure that your system meets the necessary requirements before proceeding with the installation.

I contacted Office support by chat and he sent me a link to an older version of Office the worked with Catalina.

Unfortunately the link was within the chat so I no longer have it
