Why is Adobe Acrobat Reader starting automatically when I log into OSX?

How can I stop Adobe from starting and opening every time I start up my computer?

I have both the options "open at login" and "keep in dock" turned off.  Still, it automatically starts and opens when I start my computer.

This just started happening recently.

    Correct answer NeteKoch

    I found a way to stop Acrobat from adding to 'start at login'. Or at least on my computer:

    1. Go to 'Activity monitor' kill all Adobe tasks.
    2. Go to 'Machintosh HD > Library > LaunchAgents' and delete the file 'com.adobe.ARMDCHelper.cc24ae...0d.plist.
    3. Go to 'Machintosh HD > Apps > Adobe Acrobat DC' and delete the file 'Adobe Collaboration Synchronizer'.

     

    After doing this Acrobat  gives three warnings when starting, but - in my case - the app-helper is not automatically set to start in the background. Acrobat still seems to works.

    I had the same problem, solved it by puting the Acrobat Reader icon on the dock, now it does not open on start up.

    That works for Adobe Acobat Reader - doesn't work for other Adobe apps.

    I see these posts started in 2019 and here we are in 2023 and I don't see a single solution from Adobe. This is very frustrating for me, and nothing seems to work.

    Mac Big Sur.  I have tried all thes options suggested and STILL acrobat opens full screen whenever I login.  It is NOT listed under starup items.

     

    So annoying.   I used to have Adobe Professional (paid for!) but it stopped working several OS ago and I am expected to pay for it again.  I used to like Adobe but over the years they have become so user-unfriendly with all their products I have used (Photoshop, Illustrator; In Design..)   I use alternatives whenever I can - not that they care.

    I agree, this is so annoying. So user unfriendly. I would not recommend anyone to buy this, it is very intrusive.

    This annoyed me for years. I just finally learned that our computers' system preferences have picked the Adobe Acrobat to be launched automatically at startup. You can change the setting by following these steps:

    1. Click the black Apple icon in the upper-left corner of the screen.
    2. System Preferences>Users & Groups
    3. Click on Users & Groups. It's near the bottom of the dialog box.
    4. Click on the Login Items tab.
    5. Click on the application you want to stop from opening at startup. The applications are listed in the right pane of the dialog box.
    6. Click on "minus sign" beneath the applications list. The application will be removed and will not run the next time you launch your Mac.

    Hi guys.

    Just found this and it's stopped it from happening:

    That did not stop the icon from loading in the dock!

    I have the same problem and it's annoying the hell out of me. Every time I start up my machine Acrobat DC (which I never use) opens automatically. I don't have 'Open at Login' ticked, either.

    I've been having the same problem.

    I upgraded to Adobe DC for a few months, then I didn't need it anymore, and went back to the free Adobe reader version. At that point, it started launching at start-up, taking over my whole screen. It's been driving me crazy.

    In my Adobe preferences (the top mini menu), I was able to disable launch at login. Except, my "open at login" in the bottom tool ribbon, is perpetually clicked. I can't unclick it.

    I spent over an hour on Adobe chat, and the tech just kept telling me that he was "looking into it". Personally, I think he was just delaying until I got bored. He succeeded in wasting my time and never resolved the issue (thanks Rahul).

    But I did find this online: How to Stop an Application from Opening at Startup With Mac OS X , and it does stop the full application from opening. At this moment, only the icon in the bottom ribbon appears. The full program doesn't launch, just the icon. And for now, I'll have to live with that....until I find a different/better PDF reader and bid Adobe adieu.

    I did what you did - upgraded to Adobe DC then decided to cancel, partly because whenever it opened a document, there was a sidebar with "All Tools" that was basically an advertisement for additional Adobe tools. And the user interface was not as straightforward as a simple PDF reader. Everything on this page didn't work for me - coming in through System Preferences, trying to delete login items (it wasn't even listed, but it still automatically started!), etc. 

     

    I then realized that there was an Adobe Acrobat Uninstall icon in the folder for the application (I got there by double-clicking on the icon in the dock, but I bet I could have gotten there by going to the Adobe application in the list of applications). I clicked on the Uninstall icon, and after closing all PDFs, it uninstalled the app. 

     

    Now when I click on a PDF, Preview is the app that opens it, and now I can more easily delete the pages in the thumbnail sidebar, or move them around. I'm going to test this and make sure it doesn't open anymore upon login, but it looks like this is a success.

    Rebooted. Adobe Acrobat DC is definitely gone.
