No reply ... This pushed me to dig into the Internet to learn how to write command lines in Terminal.
And I solved my problem and I provide the answer.
In fact the location where the file install.bin was located was unkown to Terminal.
The easiest way is to put install.bin on your Desktop and indicate this to Terminal in the following script :
Then you can type the two command lines :
chmod +x install.bin
And the install proceeds automatically :
installed at /Applications/TheSkyX Professional Edition.app/Contents
app dir exist
Detected platform: mac, if platform isn't correct, input your platform: 1.x86 2.x64 3.armv5 4.armv6 5.armv7. 6.armv8 7.mac:
PlugIns folder: PlugIns
install completed, uninstall file is generated at current directory
Is that not nice ?
