If you are looking to open MSG files on a Mac but don't have Outlook, there are a few options, though they can be a bit tricky. One way is to use online converters, but they often have limitations like file size or conversion errors. Another method is to try email clients that support MSG files, but they might not always give you full functionality. If you’re looking for a more reliable and straightforward solution, I highly recommend the DRS Solution MSG Converter Tool for Mac. This tool is specifically designed to open MSG files on macOS, and it lets you convert them into formats like PDF, EML, or MBOX, which are much easier to handle on a Mac. It’s quick and doesn’t require Outlook to access the file’s content, making it super convenient if you don’t want to deal with complicated workarounds.
