I can't restore the profile.

Why not? Don't you have a backup? Something called Time Machine?

Well I didn't know how to do a backup so Id didn't do a back up the Time Machine didn't work.

Make sure you can see hidden files and folders:

• http://kb.mozillazine.org/Show_hidden_files_and_folders#Mac_OS_X

MAC Profile is usually stored here: Mac OS X Profile folders are located here:

• ~/Library/Thunderbird/Profiles/<Profile name>/

The tilde character (~) refers to the current user's Home folder, so ~/Library is the /Macintosh HD/Users/<username>/Library folder.

• http://kb.mozillazine.org/Profile_folder_-_Thunderbird

'Profile name' folder is usually called 'xxxxxxxx.default', where the x's are letters and numbers. What do you see in the ~/Library/Thunderbird/Profiles folder ? Post an image so the forum can see what you have got stored.

In the ~/Library/Thunderbird folder, there should be a 'profiles.ini' file. Open this using a simple text editor program like Notepad. Post an image of the contents.

None, I told you there is NO Thunderbird Folder in the Library.

Sorry, I try this:

/Macintosh HD/Users/<username>/Library folder

But there is NO Library folder though.

Ok, I did found:

/Macintosh HD/Users/<username>/Library folder

Thunderbird/Profiles/

Nothing in that folder.

I got it working!
