git - Can't save commit messages with Adobe Brackets as Editor -

first - here's how installed adobe brackets text editor of choice in order commit messages git.

git config --global core.editor "brackets" 

here's problem i'm having....

i able add file staging area. , when type git commit mac terminal launches adobe brackets expected applicable commit_editmsg file.

i able type in message, save file, , exit text editor. when perform git log make sure recorded commit error message:

fatal: current branch 'master" not have commits yet

basically what's happening editor not saving commit_editmsg , recording file new commit repository.

does know if i'm doing wrong (possibly installation error?) or if bug adobe brackets , need use new text editor committing messages built in emacs?

thanks!
