@guidefreitas @naturfenomen @cstatz @jaxxon33 @vgiffin @Surroot @xDuk3x would you mind testing http://downloads.arduino.cc/javaide/pull_requests/arduino-PR-6749-BUILD-726-macosx.zip and report if the issue is fixed? Thanks

@facchinm Tests with 144, no menu Bar.

The Solution backported from https://git.eclipse.org/r/#/c/105553/ works fine.

@xDuk3x I don't understand, did you manually modify the plist? Or did you test the attached IDE build?

[xDuk3x]

@facchinm Sorry for my bad english, i'am from Germany. But i have good news for you.
(The Post below was for Eclipse. -Eclipse is working fine with edited info.Plist)

With the arduino-PR-6749-BUILD-726-macosx.zip

With preferred language "german" there are no menubar.
After is switch my system to english and reboot there are all there :)
