How to allow non-admin mac user to use App Store

How to allow non-admin mac user to use App Store

There are times you may need to provide a non-admin user access to purchase and install apps from the Mac App Store.  However, out of the box – the Mac Operating System does not allow this due to that user not having full permission.  When a user installs an app – it installs to the /Applications folder which requires administrative rights. In a situation where giving admin rights to that user isn’t feasible – there is a work around.

I have a non-admin user named “Tom Foolery”. I would like him to stay a standard user – but have access to purchase and install from the App Store.  Here is what I do:

Add Non-Admin User to _appstore Group

  1. Log in to the computer as a user with Administrative Rights
  2. Open up your command line by clicking the Spotlight   located in the top right of your Mac screen to search for the Terminal command line.
  3. Type in “Terminal” and then click on the Terminal app. 
    Once Terminal.app opens  you are now ready to type commands to add the non-admin user to the _appstore group.
  4. Type the following command:
    sudo dscl . -append /Groups/_appstore GroupMembership tomfoolery

    You will need to replace “tomfoolery” with your username. Don’t know what username you should use. Use the following command to list the users on your OS.

    sudo dscl . -list /Users

    Be sure to copy the username exactly as listed and insert it into the dscl command.

  5. Now login as the non-admin user and enjoy your access to the App Store!

Keep In Mind

When a user installs an app from the App Store – the App Store is actually controlling the installation and setting the permissions.  Meaning – an app installed by a non-admin user is going to be installed in the /Applications folder as user System and group Wheel.  What this means is that they will not be able to delete the app after they install it because they won’t have permission.

BASH Scripting – How To Create Executable Script

There are many ways to achieve this – but I find this to be the fastest way as it is all done through command line.

Creating The Script File

Open Terminal.app from /Applications/Utilities/Terminal.app

In the Terminal window that opens, we are going to create a directory called scripts on our desktop and then create a shell script file within that directory – use the following command:

//"mkdir" creates a directory on your desktop - no different than right clicking on desktop
mkdir /Users/yourusername/Desktop/scripts

//"touch" just creates an empty file with a name and extension you specify
touch /Users/yourusername/Desktop/scripts/kickstartscript.sh

We also need to make the script executable.

//chmod is used to set permissions - in this case, executable permissions
chmod +x /Users/yourusername/Desktop/scripts/kickstartscript.sh

You now have an executable file. You can use any text editor (may I suggest TextWranger – just do a google search for it) to open the file made in the scripts directory on your desktop. You may also use VIM or other command line text editor as well, but chances are if you are reading this – you would be better suited to start with a program based text editor like TextWrangler.

Once you have the file open – all you have to do is add

 #!/bin/bash 

to the top of your file and you are ready to start scripting.

The line above just tells Terminal that it is a bash file with bash commands.

Kickstart Man Page

Kickstart is a great utility to help you configure Apple Remote Desktop from the apple command line. There are many scenarios where you might need this – especially in bulk imaging, scripting, and/or package making. The following kickstart man page was created with the following command:

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -help

You could also do the following

sudo cd /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/

sudo ./kickstart -help

ARD has four main components:

1) ARD Helper
2) ARD Agent & associated daemons
3) ARD Menu Extra    (controlled by the SystemUIServer)
4) ARD Admin Console (if you have an Administrator license)

What this script does:

1) Any running ARD components will be stopped as needed.  For example,
   they’ll be stopped before an uninstall, reinstall, or restart
   request.  They will not be restarted unless you specify the
   -restart options.

2) Components will be restarted as required.  For example, restarting
   the administrator console forces a restart of the agent.
   Restarting the agent, in turn, forces a restart of the helper.

3) If you -uninstall but don’t specify a new installer to run, then
   the -restart family of switches will be ignored.

4) Options can be specified in any order, but remember that the
   options are ignored unless their parent options are specified.  For
   example, -package is ignored unless -install is specified.

RUNNING THIS SCRIPT FROM A GUI

You can make yourself a GUI-based kickstarter program to run this
script if you like.  The options, set in the console, can be conveyed
via environment variables to this script, per a spec shown in the
source code for this script (or the traditional way using command-line
switches).  Be sure the console application runs this script with sudo
privileges. The console should also specify its own location in the
APP environment variable, and may specify the location of a
STRINGS_FILE to use to load string definitions for any localizable
messages produced by this script.

A GUI console could stay up & running between runs of the script but
should avoid running multiple instances of this script at the same
time.

WARNING

This script can be used to grant very permissive incoming access
permissions.  Do not use the -activate and -configure features unless
you know exactly what you’re doing.

Blessing A Mac Hard Drive

Blessing Mac Hard Drive

In the world of IT, you never know what you are going to come up against. I have seen some of the strangest stuff imaginable pop up over time, Apple and PC alike. The one thing they all have in common – an end user who can provide no details to the events leading up to the event. With that being said, here is the first of hopefully many installments of my experiences and how I fixed the impossible. Okay, definitely not impossible – just checking if you are paying attention. On we go…

Don’t care about the long story? Skip it and see the direct details!

Today I encountered two iBooks that hung on the network imaging process. Naturally, my impatience got the best of me and I decided to restart them after some time of not finishing. As it turns out, the image process completed successfully – minus being able to boot.

On first startup:

I got the dreaded folder screen, but it never showed the question mark that I have grown accustomed to seeing.

I restart holding the option key just after the Apple “Chime” noise:

This allowed me to select the drive and actually boot up the computer. It was working! Kind of…

Now, I restart the computer and it boots right back to the same folder screen with no question mark. So the only way it will boot is by holding the option key at startup and selecting the boot volume.

I decide to try to set the startup disk by going to System Preferences -> Startup Disk and the drive doesn’t show up to select. Somehow, I am booted to a drive that Startup Disk doesn’t even recognize.

Boot to CD and startup disk gives me the same thing…

Summary:

1.) iBook will not boot on its own– only get Apple folder with face
2.) Can boot when hold option key and select the boot volume
3.) Hard drive does not show up in “System Preferences… -> Startup Disk” to set as the boot drive
4.) Drive show in disk utility – and verifies successfully

The Fix:

bless --folder /Volumes/YOURHARDDRIVENAME/System/Library/CoreServices --bootinfo –bootefi

I issued this command to bless (make it bootable) the system and had it rebuild the boot files needed.

Next I set the boot drive with the following command.

bless --mount /Volumes/YOURHARDDIVENAME –setBoot

NOTE: If your hard drive name has a space in it – you need to escape the space with a backslash. If your hard drive name is “Macintosh HD” the command would be the following.

bless --mount /Volumes/Macintosh\ HD –setBoot

Voila – iBook was completely fixed!

Caution:

Take this experience with caution – and if you are not sure if it applies to your situation – do not attempt it. I take no responsibilities for your problems – I do that enough in my day job!
