I installed the latest version of QGIS on Mac OS 10.7.3 with 2 additional frameworks (GDAL Complete and GSL) but there is no main menu bar (not at the top of screen, not at the window of QGIS).
Where is the menu?
Context: I believe this is a Mac issue. I had the same thing with QGIS 1.8.0 and HEAD (
d68524) built with homebrew on OSX 10.7.5. It appeared after rebooting for the first time in a long time (initially the shutdown hung, so I did hard power off and booted up, then rebooted a second time, cleanly).
Symptoms: After this the menu bar at the top of the screen (the normal Mac one) was missing for QGIS. It would just show the menu of whatever application I used before I selected the QGIS window. Uninstalling and reinstalling didn't help (I tried two versions). Command-Tab application switching didn't show an icon for QGIS. Doing Exposé's "show all windows" showed the QGIS window as a thin vertical line.
The solution for me was:
rm ~/Library/Preferences/org.qgis.QGIS*(probably not necessary, but it was one of the steps I took).
