The installation works when on laptop however, an error occurs when installing on external drive.
During the 'installation' stage
a message popped up asking if I would allow the hardware to be able to controll access to the laptop or something.. I don't rememer it clearly
and I accidentally pressed no.
I think that may be the cause of the error
however I can't find a way to undo it.
the following sequence of the windows are as below.
I tried restrating the computer and using another pkg file and it both doesn't work.
