Hi,
I have this error on macOS 12.6 :

In folder FlashTool.app/Contents/MacOS/x10flasher_native/udev there is incorrect symlink

libusbx-1.0.dylib -> /Users/emmanuel/git/Flashtool/Flashtool/build/install/Flashtool/FlashTool.app/Contents/MacOS/x10flasher_native/udev/libusbx-1.0.0.dylib

Should it be libusbx-1.0.dylib -> libusbx-1.0.0.dylib?

Should it be libusbx-1.0.dylib -> libusbx-1.0.0.dylib?

If it is meant to be a UNIX/POSIX-like symlink then you can use any name you want/need for the link pointing to the source . . .

ln -sf libusbx-1.0.0.dylib libusbx-1.0.dylib

and it's work like a charm

the origin code caused this is :

  public static final LibUsbLibrary libUsb = (LibUsbLibrary)Native.loadLibrary("usbx-1.0", LibUsbLibrary.class);
