Following Kwankyu's instructions to preface it with a PR on 39571, my build from source of Sage succeeded on my old MacBook Pro 9,2. Sage started up and executed simple tests with the following error
*Possible bug wrt Safari* The 2d test plot opened a Safari window and displayed the generated png file OK. But in the case of plot3d, Safari displays a blank window. I presume the content is is SVG. Opening the generated file with Firefox displays the appropriate 3D image. I suspect it would be useful to add a check to the Sage code to check for the target browser in the case of SVG output and offer the user a choice.
