Can I double click to run SH Files on Mac?

Normally you double-click a macOS executable within the Finder (whether it is a compiled app, or script). However, with some macOS security settings the executable may not run unless macOS is told it is safe to run that macOS executable file.

Even if a shell script is made executable, I have encountered times I cannot double-click the shell script to run it because double-clicking opens it in the text editor. For some reason macOS assigns extended attributes to the shell script file to cause it to open in a text editor. Once I remove those extended attributes (using the command line 'xattr') I am able to double-click the executable shell script & have it run. If you use a GUI app to edit the shell script, you will need to remove those extended attributes again before you can double-click the script to run it.

Not being familiar with Windows files, I will say that it takes a double click to open any file or app. You can easily check this by doing so. Keep in mind that there are Window files that a Mac can not open or run. You must install a Mac version if one is available.
