I'm wondering if there is a way to disable the auto open/auto log n when opening my computer. I have a macbook and I don't have Adobe Reader in my dock, but frequently I will open my lap top simply to browse the web and Adobe Reader it will open and if I'm not logged in it will force me to log in before it will let me close out of it. I just want it to stay closed until I'm ready to use it...
Looking at the description given above, seems you have Adobe Acrobat Reader set up in your startup programs. Which is resulting the application to open automatically on startup.
You may disable Acrobat Reader from startup menu following the steps suggested below:
Your login items are listed in settings. One of the easiest ways to control startup items is inside System Preferences > Users & Groups.
Manually removing or adding Mac startup programs
Let us know if it still doesn't help and launches Acrobat Reader on startup.
"seems you have Adobe Acrobat Reader set up in your startup programs" is code for Adobe forcefully inserted it there
Not sure why you think Adobe would do that for just a few people. Still, it's easier to blame them that actually troubleshoot.
