SearchPartyd is a low-quality application that may show up on your Mac out of the blue. Thankfully, it is not dangerous, so you should not be concerned about your online privacy and security. However, it is a Potentially Unwanted Program (PUP) that could manipulate your Web browser without your permission. The changes it brings typically concern the new tab page and search engine – it replaces them with the page it wants to promote. Allegedly, most of SearchPartyd's redirects take users through several search services before landing on Yahoo Search.
SearchPartyd is not meant to enhance your online experience in any way – its creators profit from the ads you see when this PUP redirects you. Needless to say, you should solve this issue immediately to ensure that SearchPartyd stops redirecting you.
While it might sound easy to uninstall SearchPartyd manually, we advise you not to do this. It will not ensure the full elimination of its files, and the random redirects may continue to occur. The best way to deal with Mac PUPs permanently is to let an antivirus tool handle their removal. To avoid having other PUPs on your Mac, you should consider investing in additional security software to keep you safe from suspicious files and installers. The number of PUPs, adware and malware targeting Macs has been increasing exponentially, so you should strengthen your defenses as soon as possible.
