Disable the Avid Application Manager at startup


If you have Sibelius 8 or other recent versions of Avid applications, you’ll have noticed the new Avid Application Manager. The AAM is, according to Avid, “an instrument that facilitates all the operations that relate to application download and activation, subscription prolongation, and other product licensing activities. With Application Manager, you can manage your downloads, installs, updates, product activation procedures, support plan, subscription model, receive Avid news and advertisements, and try new offerings without having to go to Avid’s Web store.”


AAM always launches itself upon startup. However, you don’t actually need AAM to be running in order to use Sibelius. Although you can quit AAM, it will stubbornly launch itself the next time you restart or log in to your computer.

It isn’t readily apparent how to disable it from automatically launching, but it’s possible. If you don’t like processes such as AAM to be running in the background, here’s how to prevent it from doing so.


Use Terminal

If you’re comfortable using Terminal (the command-line controller of the Mac OS located on your hard drive at Macintosh HD/Applications/Utilities/Terminal), simply launch it and copy and paste the following code, and then hit Return:

sudo defaults write /Library/LaunchAgents/com.avid.ApplicationManager.plist RunAtLoad -boolean false

You’ll be prompted for your administrator password. Enter it, and you’re done.

Use the Finder

If you’d rather not muck around in Terminal, you can visit the file in the Finder by going to Macintosh HD/Library/LaunchAgents.


Find the file named “com.avid.ApplicationManager.plist” and open it in a text editor. You’ll be prompted for your administrator password.

Locate the key RunAtLoad and change true to false — leave all other characters as they are.


You may get a message saying “Are you sure you want to unlock…” Click Unlock.

Save the file. You’ll probably be prompted for your administrator password again. Type it and you’re done — AAM won’t launch on startup.

Should you wish to manually launch AAM at anytime, you’ll find it at Macintosh HD/Applications/Avid/Application Manager.


There is a helpful 5-minute video which explains it all. Basically you open the Task Manager, click the Startup tab, and disable the “Avid Application Manager Helper” and the “InstallShield”.

For a walkthrough of how to do that, watch this video.

    Hi Philip,

    We’re working on improving the AppMan experience.

    It’s worth noting that you won’t get any automatic notification of updates to any Avid products, including Sibelius, if you don’t run it.

      Thanks, Joe – good to hear, and duly noted!

    I recently installed Sibelius 8.1 on an older Mac machine and was able to start it. But when I wanted to start the ApplicationManager in order to enter my data for the subscription (System ID and activation information), the AppManager could not be started because of the older OS system. Since I have to rely to the older system (32-bit issue with Kontakt), do you have a suggestion for an alternative activation process?

      We’ve been 64-bit only I’m afraid since Sib 8.0. You won’t be able to run Application Manager or Sibelius.

      There are 64-bit versions of Kontakt available – are you able to use that instead?

    I have done this procedure on pc. The only problem is that you are then unable to check for updates – AAM has to be running for that. I was happy to forego that, though, since updates are readily advertised. It is tricky to restart AAM, but it can be done, so I stick with this approach.

    Prior to Windows 8, Task Manager does not have the startup tab, so you can instead use the System Configuration tool msconfig (which is part of Windows) to turn off startup items. From the Windows Startup menu, choose Administrative Tools>System Configuration (or you can click on Run and type in msconfig).

    The System Configuration dialog has a tab for Startup, which will be full of things you will probably be surprised are loaded at startup. You can turn things on and off from here. Be careful not to just turn everything off, as some things are really needed at startup.

    The interface is a bit clunky, and you may need to resize the columns to get the whole name and the manufacturer, but it is doable. Uncheck an item to disable it on startup. When you choose OK it will ask to reboot or to exit without reboot. You may want to close down anything running, then reboot. Or even reboot at your leisure.

      Thanks, Bob, for this helpful additional information.

      My msconfig for Windows 7 shows avidappmanagerhelper but not avidappmanager.

      I unchecked the box but both the manager and the helper still load at startup.

      In other words, your remedy made no difference in my case.

      How do I stop this thing from loading?

      I’m happy to run it manually on occasion. But the vast majority of time it just sits there consuming huge amounts of memory.

    If you’re a power user/Windows geek, you may be interested in checking out Autoruns. sysinternals.com will redirect to the Microsoft Technet page where you can find it.

    Help! Installed a trial of 8.1 to see if it was worth upgrading from my 7.0. That downloaded the Avid Application Manager, but after a week I was so fed up of this seemingly pointless app opening automatically upon start up that today I uninstalled it. And now, it seems that every score I opened in 8.1 has been DELETED! Why on earth would that happen? And why would Avid make that happen? Is there any way I can get my scores back?!

    The instructions for disabling Avid Application Managr for Windows falls short for me, because I have Windows 7, and the instructions do not fit. Any chance the article can be upgraded to include Win 7?

    com.avid.ApplicationManager.plist is Locked
    Won’t allow any edits in text editor, prompt allows only making a copy of the file.
    Below is what appears when an edit is attempted. A window pops up with the following message.

    “You don’t own the file “com.avid.ApplicationManager.plist” and don’t have permission to write to it.
    You can duplicate this document and edit the duplicate. Only the duplicate will include your changes.”

    Suggestions? Avid?

    Have done everything suggested here, and it still doesn’t work. Opening file or duplicate of it from Launch Agent arrives in paragraph form with no true or false option. When I change it in Terminal, it won’t allow me to enter my password. Yes, I have gone to Get Info and unlocked it. Yes, I have created a dupe and dragged it to the desktop and tried to edit it. What next?
