By reading "*.default" above, I assume that by "file" you meant "folder", correct? Did you also read the [[Moving Thunderbird Data to a New Computer]] and [[Profiles - Where Thunderbird stores your messages and other user data]] KB articles? Most likely, your profile folder cannot be found because of an incorrect or unfound entry in the ''profiles.ini'' file. That file is only aware of the new profile created during Thunderbird install on Mac (probably also ending with .default) that you moved. * The path for your profile folders on Mac OS is ~/Library/Thunderbird/Profiles/<Profile name>/ * The profiles.ini files should be in ~/Library/Application Support/Thunderbird/ All you need to do is make sure profiles.ini contains the proper folder name you just copied, so edit it if needed. Please read the ''Moving a profile'' section of the [[Profiles - Where Thunderbird stores your messages and other user data]] article for more info. If you want, you can also ''add'' the Windows 7 Thunderbird profile rather than delete the new default one and replace it, even if it was for testing purposes if you ever run into trouble. That means you could set up the newly created profile as well (or not yet) and choose which one to use when starting Thunderbird. To do so, you would need to create another profile with the Profile Manager, exit it, and edit profiles.ini (now containing 2 profile (folder) entries) to match the copied Windows 7 TB profile folder name. More on adding and using multiple profiles and the Profile Manager can be found in the [[Using Multiple Profiles]] article.

From windows to mac is not easy. Finally i found the way to display both paths. Installed the map and changed the map name in the ini file. And.... it works. Tonnes 10 points. Thanks!!
