That certainly shouldn’t happen! So, some questions:
Did you install SketchUp properly by opening the installer and in the installer window dragging the SketchUp icon onto the Applications folder icon?
Are you installing the extensions using the Extension Manager window or the Extension Warehouse window? If not, what are you doing?
What version of macOS are you running?
Edit: a further thought:
Did you format your disk using the case-sensitive (non-default) option? SketchUp doesn’t play well with case-sensitive filesystems.
When a bugsplat occurs a window should pop up with fields where you enter your info and buttons to submit the report or not. Are you not seeing that? If not, there is something more serious going on…
“Sandbox tools” are from a su_ shipped extension, so it should be trouble free.
“Solid inspector” is by @tt_su it also needs his TT Lib installing perhaps that’s an issue ? Otherwise it’s a stable and well known extension.
“Soap bubble” is I guess “Soap Skin & Bubble” ? This tool has had many incarnations, do you have the newest version ? The EWH lists its v1.0.26 as MAC and v2019 compatible - it was published yesterday !
A few times I’ve had BugSplat hang without opening its window. Fortunately, the same info as it would send to Trimble is available in a crash log file on your Mac. The crash logs are kept in
,or if BugSplat managed to capture it, the report log may instead end with
.bugsplat.log
Note that the location is in your personal Library folder, not the system’s /Library. By default Finder hides your Library, so if you don’t see it you will have to use Finder’s Go-Go to Folder item to get there.
If you can find a crash log and upload it here, someone may be able to diagnose the issue.
That message contains a very good clue.
A case-sensitive OS for MAC is NOT recommended as it will often cause these kinds of issues - not just with SketchUp, it also breaks many other apps.
So, is your MAC’s OS case-sensitive ?
e.g. can you make two files in the same folder with the same name ?
e.g. test.txt and Test.txt
On a PC, or a MAC which is set up to be case-insensitive, only one such file is allowed… macos - How to check if my HD is case sensitive or not? - Ask Different
That begs the question “why”? That isn’t the macOS default, but in some cases IT folks configure a Mac that way for consistency with other UNIX computers. As @TIG stated, it is a bad idea on Mac because many apps, not just SketchUp, are compiled in ways that presume case-insensitive. Eventually case-sensitive on Mac will get you into trouble.
