Use the setting in the log out or restart dialog
When you log out of your Mac or restart it, deselect ”Reopen windows when logging back in” when prompted.
- Go to the Startup Programs section. Select unneeded apps and switch their toggle buttons or click the Disable button. With the application, you can even remove some startup items on Mac. For this, select unneeded launch agents and login items and click Remove.
- To remove the app, click on the – button. By doing this, it will stop the apps from opening on startup in macOS Mojave. Close the Users & Group Settings window and the System Preferences window. Now when you start your Mac computer next time, the removed apps will not open automatically. See also: How to Change Terminal Color and Font in.
Easily Disable Startup Programs on Mac. Using the aforementioned method, you can easily disable startup programs on your Mac. You should consider removing all the apps from the startup list that you do not use frequently. You can always manually open an app instead of having to open it automatically.
Or start up in safe mode, then restart normally. This doesn't change the setting, but your Mac forgets any windows that were open the last time you logged out or restarted.
If you deselect this setting and an app continues to open automatically:
- The app might be a login item. You can add or remove login items in Users & Groups preferences.
- The app might have installed its own startup software. Often this is controlled by a setting within the app. Check the app's preferences or documentation, or contact the app's developer.
Use the setting in General preferences
To prevent apps from remembering the windows they had open, choose Apple menu > System Preferences, click General, then select ”Close windows when quitting an app.”
Or press and hold the Shift key while opening an app. This doesn't change the setting, but the app forgets any windows that were open the last time you quit the app.
If these steps don't work for an app, the app might have its own setting for reopening windows. Check the app's preferences or documentation, or contact the app's developer.
(Updated on 11/6/2017)So, here’s a quick question: how long does it take for your Mac to start up? A minute? Two minutes? Five? Or just too long? One possible reason your Mac may be slow out of the blocks is that it’s trying to launch a slew of programs all at the same time.
Now, some of these programs might be actually be ones that you do want to launch automatically, such as the Safari web browser, or Apple Mail. But other, not-so-necessary programs may be piling up in your Mac’s “login items” list, too—ones that set themselves to launch automatically without asking first.
Another factor that may be slowing down your system is the Mac’s “Resume” feature, which re-opens any and all apps you had running when you shut down your Mac. That could lead to a crush of apps all trying to launch themselves at startup.
Last but not least, you may have specific programs on your Mac with “Launch at Startup” settings that you’ll need to find and disable.
Now, if you’re the patient type, waiting a little longer for your Mac to boot up so that your programs appear just as you left them might be a fair trade-off.
But if you’d rather shave a few seconds—or even minutes—off the time it takes for your Mac to settle down after hitting the power button, read on.
1. Cross items off your Mac’s “Login Items” list
Your Mac launches a series of programs each and every time it starts up. Some of these programs are critical for the smooth operation of your system; others, not so much.
To see a list of all the programs your Mac opens automatically, click the Apple menu in the top-left corner of the screen, select System Preferences, click the “User & Groups” icon (it’s under the “System” heading), pick a user (you, most likely), and finally click the “Login Items” tab.
You should now see a list of everything your Mac is launching (or trying to launch, anyway) whenever it starts up.
Some of the items will be easy to identify—in my case, I’ve got Dropbox and Google Drive (the handy file-sharing apps) listed, as well as something called an “Eye-Fi Helper” (an app that lets my Mac receive wireless images from my digital camera) and “AirPort Base Station Agent” (which keeps tabs on my AirPort Wi-Fi base station).
How To Remove Apps From Startup
To delete these or other startup items from the list (but not from your Mac, mind you), just select them and click the “-” button at the bottom of the list.
2. Keep “Resume” from re-launching previously open apps
How To Stop Apps From Opening On Startup Mac Mojave
Don’t get me wrong—”Resume” is one of the handiest Mac features, especially for those of us who like to pick up in Safari or the Calendar app right where we left off.
But if you don’t want Resume relentlessly re-launching all the apps you had open when you last shut down your Mac, you can stop it from doing so.
The next time you select Shut Down or Restart from the Apple menu, take a closer look at the window that pops up; in addition to the “Cancel” and “Shut Down” or “Restart” buttons, you’ll also see a checkbox labeled “Reopen windows when logging back in.”
Click the box to clear out the checkmark, and the only apps that’ll re-launch the next time your power on your Mac are those listed in the Login Items menu.
3. Check for program-specific “Launch at Startup” settings
So, you emptied the “Login Items” list and turned off the Resume feature, but there’s still a program that’s launching itself at startup. What gives? Well, it could be that the stubborn program has its own “Launch at Startup” setting.

Open the program, make sure it’s the active app on your desktop (just click its window if it isn’t), then find its Preferences menu; generally speaking, you’ll find it under its main menu in the Mac menu bar (like “Spotify” in the case of Spotify).
Once you’ve opened the program’s Preferences menu, look around for a “Launch at Startup” setting. If there are lots of different Preferences categories, start with “General,” then try “Advanced.” (In Spotify’s case, I found a “Open Spotify automatically after you log into the computer” setting under its “Advanced” settings.)
Found the “Launch at Startup” (or the equivalent) setting? Go ahead and disable it, then rinse and repeat for any other programs that are still launching themselves when you turn on your Mac.
