It is a useful tool for individuals who frequently work with XPS files and need a dedicated program for viewing them.

Convert the XPS file to PDF: One option is to convert the XPS file to PDF, which is natively supported on macOS. There are various online converters available such as Zamzar or you can also use Adobe Acrobat DC.

Use a virtual machine: You can run a virtual machine on your Mac and install Windows, which has native support for XPS files. You can then open the XPS file from within the virtual machine.

Ask your colleague for another file format: If none of the above options work, you can always ask your colleague to send the file in another format such as PDF or DOCX. This may be the simplest and most practical solution.
