Comment 5 for bug 1510698

Linux 12.04? If you mean Stellarium 0.12.4 this is because its hardware requirements were lower. I had an Atom netbook with OpenGL1.4 which also worked with 0.12.4, but not 0.13.*.
I don't have a Mac and cannot further comment on its drivers, sorry. On Windows, there is proper driver support for Intel HD4000. If there are no better drivers for your Mac, the 0.12 series is your other option.
