Jeff Johnson

Jeff Johnson is a longtime independent Mac and iOS developer who runs Lapcat Software and the Underpass App Company. He is best known for StopTheMadness, a Safari extension that wrestles control of the browser back from hostile websites, and for being one of the sharpest public critics of Apple's privacy decisions, including the 2020 'OCSP appocalypse' that revealed macOS was phoning home unencrypted every time you launched an app. A philosophy graduate turned code archaeologist, he writes a widely read blog dissecting Apple's broken promises and has racked up a long list of CVE security credits across macOS, Safari, iOS, and WebKit.
