Which ones? 

All of the binaries in $CBIN I have say "Mach-O 64-bit executable x86_64”  So 
that is unlikely the issue.

I haven’t installed Catalina yet, as I only have one computer that is new 
enough.  But one of the changes is they have locked down much of the file 
system, and are urging installation into /opt  (which is where X11 now gets 
installed, for example).

I have CCP4 installed in /opt/xtal/ccp4-7.0

You can do this with the tarball and manual install.

I’m going to help a student here with this today.  I’ll report back if it works.

Also, reinstallation of X11 is probably a good idea.

Sorry BTW to everyone for not keeping the Crystallography on OS X website more 
up to date.  I will try to do so shortly.  (The morale-sappers here finally got 
to me.)

Peace and joy,

Bill
