Unwanted startup items (OS Sierra)

I have gone through the step(s) of removing unwanted startup items: System prefs -> Users and Groups, etc and removed unwanted startup programs.  However, I have numerous programs that launch at login that aren't even shown there.  How do I stop these programs from launching at login?

Open the Finder.

From the Finder menu bar click Go > Go to folder

Then copy / paste the following:

/Library/StartupItems

Click Go then move files out of the StartupItems folder.

Thanks, Carolyn; but, in this folder (StartupItems) I only have two sub-folders labelled Tap' and Tun.

There are two other folders LaunchAgents and LaunchDaemons which seem to have a lot of programs listed, all with the file extension .plist.  Can I safely delete these from here?

Go to Extensions folder in the System Preferences utility.

Turn off all the extensions you don't need or don't use (like social media and others).

This also makes your computer start-up faster.

Thanks, Mac_Cat.  I don't think this is the issue I only have a few extensions (Dropbox, Calendar, Evernote..) and they are not the programs I want to prevent opening when I login.

Hi!

You might want to check out this article: https://macpaw.com/how-to/remove-startup-items-in-osx

In short, you need to remove stuff also from the following folders:

• /Library/LaunchAgents
• /Library/LaunchDaemons
• /Library/StartUpItems

In this way I finally managed to prevent both the spammy Adobe Updated and the horrible TeamViewer window from opening on my Mac :-)

Cheers,

FWIW, in many programs, start at login is optional. You need to check the preferences for the programs that are starting. If you have particular problematic programs, listing them would be helpful.

-- Some softwares (e.g. CoconutBattery and more) have a preference setting to "launch at startup", and then mostly they do not appear in the Users&Groups Login Items, and mostly not even in the StartupItems in the Libraries....

-- Tap and Tun is from software you better not have on your mac at all.

Generally, you would want to use the program's Uninstaller to remove those things. However, it would normally be ok to delete them from those folders. As removing those items may make the dependent program non-functional, it is always better to just uninstall the program altogether.

Also, StartupItems do not load at all anymore. You can just delete those folders.

I would like to make a general comment here:

"Library/Startup" folders: these are what Barney is talking about.

These are not what coccoinomane talk about: LaunchAgents and LaunchDaemons folders are not startup folders. And you should not remove anything that is connected to apps that you do not want to uninstall.

"Adobe Updated":  I don't really know what here is meant, Adobe may cause some issues when not correctly managed;

"horrible TeamViewer": there is absolutely nothing wrong with Teamviewer, unless you do not understand what it is for or how to use it.

FINALLY!!! This has been bugging me for almost a year now. Thanks. This completely corrected my issue

This may be the 'Reopen when logging back on' feature of the os.  Unfortunately, the only way to change it is to actually log out.

Well, sort of.  You don't have to completely log out, just bring up that prompt.

So go to the System Menu, choose 'Log out xxx...' and when you do, you'll see a popup that says 'Reopen windows when logging back in.' (See attached.) Uncheck that.  It will remember that setting from now on.  You can just cancel from here without actually logging the rest of the way out.

Here's a screenshot...

There are many places on your Mac where startup items (used by third party applications] are located out of site. 

To look, Open Finder.  Select Go--> Go to Folder...

Enter in each of these one at a time (browse to each folder) 

/Library/LaunchDaemons

/Library/LaunchAgents

I would not recommend you edit or remove these items if you are not comfortable with being in admin mode.  Just look unless you know what you are doing.  Removing items can cause unexpected behavior in third party software.

See anything familiar?  For example, if you use Chrome you will likely see this item:

/Library/LaunchAgents/com.google.Keystone.agent.plist

The Keystone agent is a program that from Google that checks every few hours to see if a new version of Chrome is available.

If you don’t stay on top of things you could have dozens of startup items out there.  Not all of these items are running all the time.  They may run on a schedule (like Keystone) or just at startup.  Lookup each item in Google to learn what they are (and what they are doing).

I highly recommend a program called “CleanMyMac 3”.  It has a built in “Extensions” panel which lets you view (and enable/disable) hidden startup items like this. 

FWIW, if CleanMyMac is not the worst thing you could possibly install on a Mac it's certainly in the top five. You only have to search ASC to see just how dreadful most experienced users feel it is. If you have it installed, uninstall it. If you don't, never install it.
