/* We wnt XQuartz.app to inherit a login shell environment. This is handled by the X11.sh
|
|
* script which re-execs the main binary from a login shell environment. However, recent
|
|
* versions of macOS require that the main executable of an app be Mach-O for full system
|
|
* fidelity.
|
|
*
|
|
* Failure to do so results in two problems:
|
|
* 1) bash is seen as the responsible executable for Security & Privacy, and the user doesn't
|
|
* get prompted to allow filesystem access (https://github.com/XQuartz/XQuartz/issues/6).
|
|
* 2) The process is launched under Rosetta for compatability, which results in
|
|
* the subsequent spawn of the real executable under Rosetta rather than natively.
|
|
*
|
|
* This trampoline provides the mach-o needed by LaunchServices and TCC to satisfy those
|
|
* needs and simply execs the startup script which then execs the main binary.
