Microsoft said today that it will no longer support its MSN for Mac OS X software, and that customers will need to access the services via a web browser. “Beginning May 31, Microsoft will make changes and no longer support the MSN for Mac OS X Internet Software client,” the company said in a statement to MacMinute. “Instead of accessing MSN services using the MSN for Mac OS X Internet Software, which is a local email client and dashboard for browsing MSN services, customers will now access MSN services and features via their preferred browser and by setting up a MyMSN page to serve as a portal to their favorite online destinations.”
