Massimiliano:> How TeXmacs has been installed on your system?

by double clicking Texmacs-1.99.8-yosemite.dmp in Downloads
and then using the texmac-1.99.8.app on the dock or in the lounchpad.

Massimiliano:>  What happens if you move away your ~/.TeXmacs directory
                            .. and restart the program?

> THAT's the solution ! <
Now all text in cells and all special text inside the main text is visible.
Wunderful.
I tested your advice with MacOS Mojave on my MacBook Air.
Later I will repeat it on my iMac.

Again, thanks a lot, Massimiliano, I would not have had this idea for 
myself!

Yours
Wolfgang

How TeXmacs has been installed on your system?

What happens if you move away your ~/.TeXmacs directory, for example 
renaming it

mv ~/.TeXmacs ~/.TeXmacs-old

and restart the program?
