Make a simple OS X Application (Mac OS X 10.10+) from bash script (shell script) that we already have.
We have a bash script.
Scripts are running sequence of commands (about 1000 lines of code) like downloading drivers, unpacking, installing them.
... In fact it is necessary that a user does not see the terminal window, but inside the application can work the same way as does the script.
See script in attach and detailed task.
IMPORTANT: Please review the script and make your price quote and add cover letter.
