OS: OS X El Capitan (10.11), Arch.: x86_64, MuseScore version (64-bit): 3.0.0.19704, revision: e96bb91

Prerequisite:
Preferences -> "Continue Last Session" enabled.

File -> Score Comparison Tool
opens the embedded dialog at the bottom of the screen.

Open a score (any, even a new/blank one)
Score 1: the file, Current Version
Score 2: same file, Last Saved Version

File -> Score Comparison Tool removes the embedded dialog, but not the temporary tab

If I close the app and restart, without closing the temporary comparison tab first, it does not ask if I want to save the file (correct since the file is temporary)
When MS starts up, I get error

(red exclamation): Cannot read file /var/folders/yw/6py_726s1gs4mh3nz0mw1vd80000gn/T/[Last saved version] 3.0_blank.s12588.mscz:
No such file or directory

Workaround: close any comparison tabs before shutdown to avoid the error message.

Fixes (suggestions)
a) Do not try to save any temporary comparison files on shutdown, or
b) Discard / ignore temporary comparison files saved in the last session when starting up and resuming the last session
