failure of Texshop download

[J. Chris Fisher]

Help wanted!  I had to upgrade my iMac to 

macOS Catalina 10.15.7.  

My old Texshop no longer works and had to be upgraded.  I went to the TEX users group web page

https://tug.org/mactex/ <https://tug.org/mactex/>

and used the installer to put MacTeX on my computer; I got the message that 
“the installation was successful.”

For a test run, the program opened to the familiar TEX page.  When I tried to typeset a file, the console appeared, but nothing happened.  In particular, there was no error message and NO auxiliary files were produced.  To make sure that I was doing everything correctly, I tried typesetting an old file that I knew had no errors, but again there was no action — no error message.  I then tried “Latexit”, and got the error message ”unexpected error, please see 'LaTeX> Display last log’ ”
