Does anyone in the Apple community still have a copy of macOS High Sierra Vers. 10.13.6 ? I want to re-install the OS.
Here is an Apple article with instructions for downloading various macOS installers:
How to download and install macOS - Apple Support
Here is another Apple article with instructions for creating a bootable macOS USB installer (highly recommended):

You should also be able to use Internet Recovery Mode using Command + Option + R to access the online macOS High Sierra installer although people have been reporting a mixed success rate for the past couple of years since it appears Apple is not actively maintaining support for this option. Here is an article for one error you may encounter (server not available)...see Fix#3:

My screenshots were landing in a single file on my desktop. I attempted to do some file maintenance & now all my screenshots clutter my screen.
How do I get my screen shots to land in a specific designated file again?
Don't you mean a designated location? A folder rather than a file?
Yes, I've tried using Terminal commands defaults write com.apple.screencapture location (enter ) dropping the new file name where I want screenshots to land, followed by killall SystemUIServer (enter) and again NADA happens & me next screenshot clutters my screen.
You need to drag & drop a folder onto the open Terminal window. Plus you need to make sure you have at least one space after "location" before you drag & drop the screenshot destination folder onto the Terminal window.
Here is an article which has the instructions (skip the first part since it deals with using the special command sequence with F5 which was only introduced beginning with macOS 10.14 Mojave.

FYI, you need to be very careful entering any commands on the command line since even a simple typographical error could lead to something disastrous occurring. There are no safety nets when using the command line and it is not always simple to revert a change unless you happened to make note of the value of the original setting. It is also not easy to restore the modified file from a backup since many of the Terminal commands may be modifying more a different file when using a different key/value command setting such as the one you have attempted to use. Plus the screenshot in the MacWorld article I linked actually has a mistake because there is no space after "location" which proves my point about how easy it is to make a mistake.
When posting any commands used within the Terminal app, you should place those commands here using the Code Insertion tool which has an icon that looks like "</>" on the forum editing toolbar. It just makes it easier to read the commands since it utilizes a fixed size font which allows us to better identify potential mistakes with any commands used.
