After running the installation application the icon appears in the menu bar on the desktop. Finder is at the top, Launchpad is next, then various other pinned applications. And just above Trash, Downloads and documents is the LibreOffice icon. I can click on it and it runs just fine from there.
When Mac logs-out, LibreOffice disappears from my menu bar. I can’t find it (as described above in Finder or Launchpad). To again use LibreOffice I have to run the LibreOffice.app and complete the install process again.
I presuppose that I’m doing something wrong. However, I don’t see where I’m taking some wrong choice in running the installation. I’m offered no prompts to respond to. Installation seems to run completely normally.
I can imagine that I could be failing to prepare the “ground” for installation. However, from the instructions in the read me file the only things I can see is to close all other applications (which I did), make sure that I have enough memory and rights.
