Elaine and Tom,
Thank you for your replies. Selecting atoms and ribbons works as it should, but ctrl-clicking on surfaces has no effect whatsoever, be it before or after splitting. I could use Sc only because I selected the whole model using the command line. Splitting does work and I get a bunch of pieces, but I have no obvious way to select the distinct surfaces. Also, I’m afraid that using visiblePatches or any other method that involves selecting all residues that define the blobs would be extremely cumbersome in my case. As I said, if I ctrl-click on an atom or a ribbon, it gets selected, is highlighted in green, and the magnifying glass icon turns green as well. However, if I then ctrl-click on a surface, the selection is cleared (status bar displays “selection cleared”).
The graphics driver incompatibility actually seems a likely culprit. I think the previous time I used this feature, I was still on my old laptop. I am currently running Chimera on a 13-inch Early 2015 MacBook Pro (MacBookPro12,1). It has a built-in Intel Iris Graphics 6100 chipset. Could there be an easy hack/workaround on my side or a software patch? If not, then I guess I’ll go and finish that particular figure on another computer :)

If not then it is probably a graphics driver problem, since some graphics capabilities are needed to know what object is under the mouse. Another possible graphics driver problem is the green outline is not shown — but if you select something the magnifying glass icon in the lower right corner of the main Chimera window (select inspector) should turn green.

I can display the MSMS surface and split it into pieces (accelerator Sc), but then I need to select the extra surfaces to hide/delete them (starting with the main outer surface). For some reason surface picking with mouse (Ctrl + left click) doesn’t work. I checked the surface attributes and ‘selectable with mouse’ was true.
