2018 iMac with High Sierra sometimes boots with no cursor -- a fix

I purchased an iMac all-in-one machine in June 2018. An immediate problem I encountered was that the machine sometimes booted with no cursor. The mouse and keyboard are both wireless. The keyboard always worked, but the mouse was rendered useless whenever the machine booted with no cursor, which was intermittent. Turning the mouse off and on (after fully booting) generated a screen acknowledgment that the mouse status had changed but did not bring up the cursor. The voice assistant Siri was no help...

NOTE: See updates at bottom of this post - last 1/5/19

Way back around new year's day during the winter of '19 (remember that kiddies?), LQ member Beryllos posted a New Year Puzzle and programming challenge in the Programming forum.

The goal of the puzzle is to generate as many whole numbers as possible between 0 and 100 using only the digits of the year, 2,0,1 and 9 in simple constant arithmetic expressions such as 9 * (10 - 2).

The rules are simple,...

NEWS 190104 ABOUT ExTiX LXQt Mini 19.1.3, Build 190104
I’ve made a new “mini” version of ExTiX. The ISO file is now only of 837 MB, which is good if you want to run the system superfast from RAM. This build has everything Build 19.1.2 has except for Kodi 18. You can, however, install Kodi 18 Leia if you want. Use Synaptic for that. Watch this screenshot. You can (of course) install thousands of other packages if you want. Study all pre-installed packages in ExTiX 19.1.3.

ExTiX 19.1 – Build 181228
I have made a new version of ExTiX – The Ultimate Linux System. I call it ExTiX 19.1 KDE/Kodi Live DVD. (The previous ExTiX KDE version was 18.6 from 180602). The best thing with ExTiX 19.1 is that while running the system live (from DVD/USB) or from hard drive you can use Refracta Snapshot (pre-installed) to create your own live installable Ubuntu system. So easy that a ten year child can do it! As an alternative to KDE you can run Kodi 18 Leia. Just start Kodi like...
