Erro executing Mac OS version of Exiftool

[rawrecruit]

HI,

I have just installed the Exiftool for Mac. Really looking forward to using it. In the past I used Windows VM to achieve the same.

When I run it from within the new Mac ExiftoolGUI I get an error when trying to alter GPSAltitude:
/bin/sh: GPSAltitude: Read-only file system
/bin/sh is the shell command in Mac so why is it trying to write to it?

I'm not sure if it's a ExiftoolGUI issue or an Exiftool issue. It works fine under windows so I'm assuming it's the MAS implementation.

Thanks

GUI for the Mac?  I think you need to ask the author of this software.  I've never used it.
