Once I have done that (just once) what I get the next time I try to click on a link is precisely what your screenshot shows.  The tool is elusive, but even if I do catch it, I can no longer automatically jump to the appropriate new page.  I tried this yet again (that is, I re-typeset the test file)

Once that has happened, though, it never happens again.  Every subsequent time if I either click or hover over the linked item, I get the preview box, and (I think in either case, but certainly if I click on a link) I get what you are calling the tool-popup, but I am unable to jump to the appropriate page.

Howdy,

I've discovered something relevant to this hyperlink problem.

I have had the Mouse Mode in the Toolbar of the Preview Window default to the Small Magnifying Glass. I noticed quite a while ago that when I typeset a document and TeXShop opened up the Preview Window the Mouse Mode wasn't initialized properly; e.g., clicking in the window wouldn't open the Small Magnfying Glass. At some point recently I opened up the Help->TeXShop Tips and Tricks document and was surprised that the Mouse Mode was initialized in that case and hyperlinks didn't work at all! However, if I selected the Text, Hand or Selection mode hyperlinks worked perfectly. Once I set the default Mouse Mode to Text mode I have had no problem at all with hyperlinks. The combination of initially being in some unknown initial mode and having the default being one of the Magnifying Glasses is what was giving the strange sometimes working and later failing problem.

So the solution for the problem is to make the default Mouse Mode found on the Preview tab of TeXShop->Preferences to Text (or Hand or Selection) mode.

I've reported the problem to Dick Koch and the next update to TeXShop will fix  the initialization problem but it will still be necessary to set the Mouse Mode (either by the default setting or by clicking it in the Toolbar) to Text, Hand or Selection mode. Also, I wouldn't expect an update to TeXShop until Big Sur (macOS 11.0) comes out.

Good Luck,
