The article delves into the challenges and methods of testing Internet Explorer (IE) on Mac systems, highlighting the historical decline of IE in favor of modern browsers like Microsoft Edge. Despite its diminished market presence, IE still holds a notable share of internet traffic, necessitating compatibility testing for web applications, especially for specific sectors and geographic regions. Since IE is not natively supported on macOS, the article outlines various strategies to test its compatibility, including using Safari's developer tools, deploying virtual machines, and leveraging cloud-based platforms like LambdaTest. These methods offer developers and testers the ability to ensure website functionality across different browsers, catering to the persistent niche user base of IE even as it fades from mainstream usage.
