Xcode [no idea what it is] popup window after crush

After a recent crush [crush report has been sent] I got this thing that popped out.
not knowing what it is [it came on when Rhino was already off [crushed] I opted for the Not Now option.
Do I need to install that…? I’m curious as Rhino was running fine without it until now.

thanks a lot

You can ignore this dialog. Just click “Not Now.” I can’t remember why this sometimes appears (it shouldn’t)…but I know I’ve seen it happen previously.
