Hey! Users have reported issues with opening MS Office documents (such as .docx and .pdf files) in Canvas on Mac computers, where files either appear blank or do not display properly. These issues are often related to browser compatibility, out-of-date browsers, or the absence of necessary applications (e.g., Microsoft Word or Adobe Acrobat) on the Mac. Solutions suggested by the community include ensuring that the browser is up to date (especially Safari, which updates with the macOS), trying alternative browsers like Chrome or Firefox, checking Canvas browser requirements, clearing cache and logs, and verifying that the required software to open the file types is installed on the Mac. If issues persist after these steps, I recommend contacting Canvas Support for further assistance.
