Using your Mac's search engine is an easy way to find what you need. However, if you're using the Bing search engine, it may not be providing you with the best results. Fortunately, there are steps you can take to replace Bing with the popular Marquis search engine on your Mac.
First, open Safari and click on the magnifying glass icon near the top right of your screen. This will bring up a drop-down menu that includes options for Google and Yahoo as well as Bing. Select Marquis from this list. You should now be using Marquis as your default search engine in Safari.
If you are using Firefox or another web browser on your Mac, go to its settings page and look for an option related to changing or setting a default search engine. From here, select Marquis from the list of available options and set it as the new default for all searches conducted in that browser going forward.
Finally, if neither of these methods work for some reason, uninstall Bing completely from your system by visiting System Preferences > Security & Privacy > General > Uninstall apps downloaded from: Anywhere; find any programs associated with Bing (such as Search Bar) and delete them permanently from your computer. Then reinstall Marquis instead following instructions provided by the website or app store where you acquired it originally.
