Mac – Enable sudoing for the logged-in user for one specific prefpane only

macmojavesudo

We are running OS X 10.14 VMs hosted on VMWare ESX.
Users log into the VMs via Screensharing app.
VMWare sets the resolution settings to an odd value, so the users would have to use a VMWare command line tool to change the setting to their needs.
Since most users are not capable of using the command line, I installed a PrefPane on the VMs:
VMware.prefPane. Works pretty good.
In order to set the resolution setting boot-persistent, you need to enter an admin pw, which no user is allowed to.
So I would like to change the sudoers file as follows:
Allow sudo for

a specified account or the logged-in user
only for the purpose of changing resolution values via the VMware.prefPane.

Can someone give me a hint on this …?

You have to script a task to run from the command line for sudo to grant password-less admin rights. It only works on shell scripts and not the GUI password prompt.

The first way to help you is to clarify you have two problems.

Make a terminal command into an app that can be clicked so you don’t have to train people in terminal app. (A very valid and worthwhile exercise to solve a general class of problems)
Make a command line tool that does what you need - which solves your specific vmware control issue or blockage.

Once you have solved both of these sub tasks, you may or may not need a third question on how to combine two working parts together.

Mac – any way to remap keys for only one app

Keyboard Maestro might be your thing. Make a new command group which only applies to the application in question, then for each key you want to remap, make a new command with a hotkey trigger set to the real key and an "Insert Text" action set to what you want the key to be.

The only shortcoming I've found so far is that it can't handle the in-built volume control keys on an Apple keyboard. It can detect them & act upon the event, but it can't suppress the volume change. In fairness, nothing else can either. Most programs I tried can't even detect it. Keyboard Maestro is the king of the pile.

Is it possible to extend the time i’m logged as administrator when enter sudo mode from the console

In the terminal type this to open a file to edit:

sudo visudo

Find this:

Defaults        env_reset

And replace with this:

Defaults        env_reset,timestamp_timeout=NUMBER

Where NUMBER is the number of minutes to time-out.

Then save the file.
