As if Apple build in some safe guards that prevent scripts being executed with root privileges from within Java. When I change the first script to use osascript, again with confirmation that everything is correct as far as the script goes, I don't even get a prompt when it runs from within Java. Not even the first logging output from the second script appears. ![]() When launched from the Java app, I do get the cocoasudo prompt, but nothing happens. And they work fine when launched manually (with normal user privileges of course) from the command line. I have confirmed via extensive logging into separate files that the scripts indeed do what I intended. The idea is of course to use cocoasudo in the first script to perform the second script with root privileges. The second script performs all steps that need root privileges. The first script is executed from Java with some command line parameter. ![]() ![]() To save other people some time, I post my own findings:įirst of all, like the poster of the question, I also have the situation that I need to elevate permissions from within a Java application.
