kflash_gui 1.5.2 when executed clicking on its icon is closing immediately on osx.
It needs to be launched from Terminal, with for example open /Application/kflash_gui.app

I had to reduce baudrate to 115200 to have it succeed flashing a firmware too.

@phjo33 1.5.2have a bug: it will fail to start when the last file selected not exit, you can delete .config/kflash_gui/kflash_gui.conf file and then restart.
and you can try to select slow mode but not set baudrate to 115200

[phjo33]

Deleting kflash_gui.conf does not change a thing. kflash_gui actually never stays opened when launched with double clicking its icon. The reason I tried running it from the terminal was I supposed an error message would appear, which it did not...

I'm pretty sure slow mode did fail previously with default baudrate, but right now I tried and it worked.

@phjo33 emmm it's pretty weird but I'm not familiar with macOS, but it works on my mojave

[tongjinlv]

Hi,

I have the same issue on a fresh MacBook Pro (15-inch, 2018) running 10.14.6 (18G87). I tried deleting the kflash_gui.conf by executing rm .config/kflash_gui/kflash_gui.conf but the result was the same (i.e. the app quits immediately after a double click). To make sure, I confirmed with v1.3.2, v1.5, v1.5.1, and v1.5.2. With all versions, open /Applications/kflash_gui.app works for me.

I have the same issue of Kflash closing immediatly on macOS.
invoking directly brings the error

LSOpenURLsWithRole() failed with error -10810 for the file /Applications/kflash_gui.app.

using 1.5.2 (latest for macOS)

I have managed to fix the launch by running it on the terminal by:
cd folder-where-it-is-the-app
and
./kflash_gui.app/Contents/MacOS/kflash_gui

hope might be helpful to some .)

[fanhuafeng]

open terminam and run cmd:
/Applications/kflash_gui.app/Contents/MacOS/kflash_gui
the kflash_gui is run ok!!!
