# Summary
Popular macOS apps with a file-sharing functionality didn't delegate file quarantine to OS leading to File Quarantine bypass (Windows MOTW analogue) for downloaded files. The vulnerability has low/moderate impact, but it can be combined with other custom behaviours, and UX features to increase the severity.
During the research, I also discovered two "insecure features" in macOS: dangerous handling of .fileloc and .url shortcut file
