Hi, there,
On Mac, if I run a command in terminal and start a GUI application,
the new window is always hide behind the current window. So does
start apps from other application like firefox.
But noticed that double click an icon in "Finder" can start it
correctly. So I did some test and found that if I wrap the command
into a fake ".app" folder and use "open -a fake.app", it'll show the
new window in the front. It's not good solution and I'm sure I
haven't got the root reason.
I suppose there is an option in the configuration file of window
manager for MacOS to control this behavior. Am I right? Anyone has
any idea on what that option is and how to change it? I'm going mad
with this problem.
It is an effect of using LaunchServices, rather than vanilla fork/exec
or posix_spawn to start the process.
If you want this behaviour, use LaunchServices (which is what the
command line tool "open" does). This will have the side effect of
running the correct slice of the application, for example if you
checked the "Run under Rosetta" checkbox in finder for Safari to
ensure you will be able to continue to use your PPC plugins on an
Intel machine.
