SponsorBlock
SponsorBlock for Safari helps skip sponsor segments and other marked parts of YouTube videos on macOS using a community-driven database.
What is SponsorBlock?
SponsorBlock is a Safari app and extension for macOS that helps YouTube viewers automatically skip sponsor segments and other non-essential parts of videos. It is built around a crowdsourced system where users mark segments such as sponsorships, intros, outros, self-promotion, and subscription reminders so they can be skipped for everyone else. On Mac, users typically install it as SponsorBlock for Safari and enable the extension in Safari to control how different segment categories are handled. The app also lets users submit new segments and vote on existing ones, which helps improve accuracy over time. It is best suited to people who watch a lot of YouTube in Safari and want a cleaner, less interrupted viewing experience. SponsorBlock is published by Ajay as part of the broader SponsorBlock project.

Safety overview
Status: Mostly safe
This is a legitimate Safari extension for controlling how YouTube segments are skipped. It normally needs permission to work with YouTube pages in Safari, which is expected for its purpose. Because it relies on a shared community database, skip points may occasionally be imperfect, but the practical risk is usually limited to a segment being skipped or shown incorrectly rather than harm to your Mac. Keep Safari extensions updated and review site access in Safari if you want tighter control.
Recommendation: Keep SponsorBlock if you use Safari to watch YouTube and want automatic skipping of sponsor and filler segments. Remove it if you no longer use the feature or prefer not to grant a browser extension access to YouTube pages; disabling the extension will stop its skipping features without affecting the rest of macOS.
