TOPIC:

Updated from 5.6 to 5.7 and then 5.8 on MAC with ElCapitan. I have a working icon for CodeTyphon Center, but not the IDE. The Center does not have an icon for it in it's toolbar either. I've tried rebuilding CT for both Carbon and QT4. No joy. What went wrong?

Please give us more info Sir

My suggestion:
-Download CT 5.70
-Install CT 5.70
-Install Sys Libraries
-Update with CTCenter to LAB CT 5.80
-"Remove and build ALL"

Those are, indeed, the steps I took before I wrote.
I will admit to being more a Windows user (BTW - the update went fine there), so I don't know for certain where to look in the file system for the .app.
Perhaps it is there and simply the icon is missing. But one would think CT Central would show something in its tool bar if it existed, but the space where it was is blank.
