I have used Thunderbird for years and have successfully transferred Profiles from Pc to PC. Now that I want to move Profiles to a new mac, I've hit problems. in fact I now have multiple problems. 1. I renamed the profile in Libraries on the mac, and now Thunderbird wont even start. I uninstalled and re-installed, but with the same result - Thunderbird won't start (Profile missing) 2. Now that I can't start Thunderbird, I can't access the Profile Manager. WHY IS IT SO DIFFICULT TO ACCESS PROFILE MANAGER ???? 3. Assuming I can get Thunderbird working again on the mac, how to I quickly access the profile Manager to choose which Profile I want to run thanks, mike
