Hi Bruce, 

Welcome to Box Community. Let me see what I can do to help!

After installing Box Tools v4, navigate to Preferences > Extensions in Safari's menu and check Box Tools Safari Extension. If you do not see Box Tools Safari Extension in Safari's Preferences > Extensions, please close and reopen Safari, and attempt again.

My Safari does not have preferences and under Safari Extensions Box tools is nowhere to be found.

This is still a problem for Mac users, it isn't solved.  How do we make this work?

I am having this trouble now, have uninstalled box completely, restarted, and reinstalled box drive and box tools - no change.

I found the Safari Extensions under preferences, but even after restarting, can’t find the Box extension. It also doesn’t appear to be in the App Store.
