Improvements

You try all sorts of things when you have problems with the computer.

I upgraded the RAM.   I THINK that helped.  There are SOME warning messages I no longer get.  

But there were some suggestions of other problems.  So I deleted all caches and most cookies.  That helped, but some I will will have to re-enter.

I bought some new stuff to increase the directness of the ports my peripherals prefer.  That sounds strange but peripherals have options on connections and some are better than others.  I spent a day last week looking at the options.  

A lot of my stuff is old.  It is odd in a way to think of HDMI connections as "old".  Once, they were "best tech".  But things change and I don't always notice.  And problems sneak in gradually.  I have them.

So the RAM-upgrader tech guy explained "thunderbolt" connections, and Bluetooth.  Well, I thought "Bluetooth" was just for wandering around with a mobile laptop.  Was wrong.

He suggested a few cool add-on hardware things.  I checked them out pretty carefully and ordered a couple.  And, granted, this is all Mac stuff...

First was a multiport hub that fits under my Mac-Mini...

It adds many ports and uses only 1 USB plug..  And I needed them all.  And it made it easier to organize my cables.

He also suggested a Mac-dedicated keyboard.  I ordered that too.  It is Mac-dedicated.

It is good.  Macs have dedicated symbolic keys that keyboards that work for Mac and PCs don't have.  You have to figure them out on a combination keyboard and learn to interperate.  That's a pain.

So the Mac-dedicated keyboard is good, too.
