## Questions & Answers

**Q: will it work with mac os 10.10 yosemite?**
A: I use it daily on Catalina (10.15) and Big Sur (11.0 and now 11.5)  The initial upgrade to Big Sur was slightly painful with the KensingtonWorks software, but they claim support for versions much earlier than Yosemite, so it should work.  Just don't count on a smooth process if you ever bring yourself up to date.

**Q: Any plans for the same mouse without the track ball?**
A: search for ergonomic mouse instead of ergonomic trackball

**Q: Is there a white wired version?**
A: I'm sorry that we only have black version for Pro Fit Ergo Vertical Trackball.

**Q: My hand length is 7 1/2", is it too long for this mouse?**
A: No.
