Zipster: Mount ZIP Files in the Finder (and Only ZIP Files) But it’s hard to complain too much: this is a free application that opens ZIP and RAR files instead of unarchiving them. And the software will occasionally “encourage” you to download Trend Mirco’s anti-malware software, along with a few nags asking for App Store ratings. The interface doesn’t quite feel native to macOS, owning mostly the the ugly toolbar buttons. Having said that, there are a few downsides. Finally there’s the Share button, which lets you quickly send files to any program that supports the Mac share menu. “Extract” will extract all files or your currently selected file, while “Secure Extract” will scan files for malware, assuming you’ve downloaded Trend Micro’s Mac Malware scanner. “Open,” somewhat confusingly, opens a new ZIP file: it does not open files in the current ZIP file.
