thanks for your reply. But helas, but the same problem still arises.
After starting Komodo the ‘I am busy’ wheel imedeately starts spinning and doesn’t stop (until I force Komodo to stop). So I cannot even open the Troubleshooting function.
I have also followed the instructions from teh site you refer to, but I constantly got the message that the file or folder could not be found.
I have also completely removed the profile folder (in fact I renamed it), and after starting Komodo I got the three screens, asking me for the setup of the program and after that, the ‘I am busy’ wheel took over again.
Completely uninstalling Komodo and reinstalling it: same result.
Fortunately I can use Windows version of Komodo (under Parallels), so I can go on, but it is strange that the Macos version refuses to work.
Thanks for looking as this problem
