No, you do not need a special PC or Mac to use CMS. Any computer that meets the minimum system requirements can be used to run CMS. The minimum system requirements are:
-A processor with a clock speed of at least 1 GHz
-At least 2 GB of RAM
-At least 10 GB of available storage
-A display with a resolution of at least 1024x768 pixels
Additionally, your computer will need to have an internet connection and a web browser in order to access CMS. CMSs are usually accessed via a web browser like Safari, Chrome, or Firefox. However, some CMSs do have specific system requirements, so it's always best to check with the CMS provider before purchasing or using one.
