Apologies for my delay in replying to your excellent question. It turned out that none of the other 10 Macs on site were OS X 10.12 capable.

As an alternative approach I created a new OS X 10.12.6 system on a new drive, followed by a de novo build of QGIS3. My reasoning was that since the Mac mini I had been using was trouble-free with a wide range of programs, including QGIS 2.18.15, that it was OK as hardware, but the problem might lie with system software.

Steps were:
1) download (Apple) and clean install of OS X 10.12.6 onto FW3T_A (no pre-existing System)
2) boot to FW3T_A & run Software Update until no more available
3) download (Apple) & install
Xcode 9.2.xip
Command Line Tools (macOS 10.12) for Xcode 9.2.dmg
4) Software Update (no updates found)
5) download (macports.org) & install MacPorts-2.4.2-10.12-Sierra.pkg
6) in Terminal
$ sudo port selfupdate
$ port info qgis3 {reports qgis3 @3.0.0_1 (gis) …}
$ sudo port install qgis3

Log of qgi3 3 install in attached "1_QGIS3_port-log.txt"

Started QGIS3,
"Welcome to QGIS 3.0.0-Girona" window opens
choose clean start {no import from QGIS 2}
small green window, "loading GUI…"
new window appears in front: “Problem Report for Qgis 3”
window is owned by "Problem Reporter" app, Parent Process: launchd, User
a crash log is actually created in
~/Library/Logs/DiagnosticReports/Qgis3_2018-03-10-233353_Garths-Mac-mini.crash
(whose contents match Problem Reporter window contents)
the Problem Report for Qgis 3 window says:
"Qgis3 quit unexpectedly
Click Reopen to open the Application again. This report will be sent to Apple automatically.
> Comments
Problem Details and System Configuration

followed by lengthy debugging information which is in attached "2_QGIS3_start_problem_report.txt"

However, QGIS3 has not actually crashed.
Its main window appears normal and is functional.

Furthermore, dragging Processing Toolbox out of main window and then back in now does NOT crash QGIS3 - so the clean system install has changed something.

However, there are still errors and warnings in the Log Messages pane (as previously reported in #18381).

These Log Messages contents are in the attached "3_QGIS3_Log_Messages.txt"

Quitting and restarting QGIS3 has identical result, except without the "Welcome to QGIS 3.0.0-Girona" startup window. First comes the small green window, "loading GUI…" then the Problem Report window, then the main QGIS3 window. Each time a new ~/Library/Logs/DiagnosticReports/ report is created without QGIS3 actually crashing.

Deleting the QGIS3 folder in ~/Library/Application\ Support/QGIS/ and restarting QGIS3 causes it to start with the "Welcome to QGIS 3.0.0-Girona" window and to create a new QGIS3 folder, but otherwise same issues. Rebooting the system does not change anything.

A directory of ~/Library/Application\ Support/QGIS/QGIS3 is in the attached
"4_QGIS3_Files.txt".

The attached "5_QGIS3_ProblemReporter_Open_Files_and_Ports.txt" shows Activity Monitor info about the Problem Reporter app when it is displaying the problem report.

I will try a clean QGIS3 rebuild on my original boot disk to see if that gets rid of the Processing Toolbox issue and report back.

However, it does seem that there are some significant issues reported in Log Messages "Python warning" and "Processing" panes.

Many thanks for any assistance you can provide!

Unable to reproduce on MacOS 10.14 (18A391) with QGIS 3.3 master. Garth mentioned it cannot be reproduced with 3.0.2
