By default, your Mac will open it with TextEdit, Apple’s built-in simple text-editing app. To change that, Ctrl+click the file in question, then click Get Info. This will bring up a new window. Use a Program Once to Open a File. What if you wanted to use a particular program to open a file once, but not make it the default program? We’re going to tell you how to do that, too. Right-click by touching two fingers to your Mac’s trackpad and click or right-click your mouse on the file. The first option in the listing will have (default) written behind the app. This signifies that the app is currently the default PDF viewer on your Mac. Now that we have discovered it, let’s get down to switching the default PDF viewer. To Change Default PDF Viewer on Mac.
If you’ve ever tried to open an app from an unidentified developer on your Mac, you know that it can be a tricky task. macOS has security measures in place that block this action in the hopes of protecting you from malware. That being said, it’s not impossible.
Here, we’ll talk about apps from unidentified developers and show you how to allow them on your Mac. We’ll also go over some tips for staying safe when downloading new software.
What is an unidentified developer?
An unidentified developer is an app developer that isn’t registered with Apple. Generally, apps from unidentified developers haven’t been reviewed by Apple for safety and security.
Apple believes that one of the easiest ways to distribute malware is to insert its code into an app. That’s why they check apps thoroughly before allowing them to release to the Mac App Store. Apps from unidentified developers aren’t on the App Store.
This doesn’t mean that apps from unidentified developers are malicious (although they can be). They can either not comply with Apple guidelines, or be created before the ID registration started.
Why your Mac shows a warning?
In order to protect your device from dangerous apps, Apple includes security measures in their devices. One example of this is Gatekeeper. Gatekeeper is Apple’s program that recognizes whether an app has been downloaded from the App Store. This program warns you when you’ve downloaded and attempted to run software from another location for the first time.
When you receive a warning about an app, it’s because Gatekeeper flagged it as a potentially dangerous app. This doesn’t necessarily mean that the app has malware—it simply means that macOS doesn’t recognize the app (or the developer). Because of this, you won’t be able to open the app as easily as you would an app that’s been vetted and listed on the App Store.
Luckily, it’s a bit easier to download apps from unidentified developers onto your Mac than onto other Apple devices.
How to set your Mac to allow apps from unidentified developers
By default, your Mac is set to block you from opening apps that haven’t been verified by Gatekeeper. Black market mac apps. This includes both apps that aren’t from the Apple App Store and those that come from unidentified developers.
It’s a good idea to start by first setting your Mac to allow you to open apps that aren’t from the App Store.
Setting your Mac to open apps not from App Store
By setting your Mac to open apps that aren’t from the App Store, you reduce the number of warnings you’ll get when opening third-party applications. This makes it much easier to open these kinds of apps.
Here’s how to change your Mac settings to allow apps from third-party locations:
- Open your Mac’s System Preferences.
- Click on Security & Privacy, then go to the General tab.
- On the bottom left, you’ll see a padlock icon. Click on it and enter your admin password.
- Under “Allow apps to be downloaded from”, select App Store and identified developers.
Once this is done, you’ll be able to open most of the apps that aren’t on the App Store. However, you still won’t be able to open apps that aren’t recognized by macOS.
Setting your Mac to open apps from unidentified developers
If you want your Mac to allow apps from unidentified developers, you’ll have to follow a few additional steps. Firstly, try to open the unrecognized application. You’ll see a notification that it can’t be opened. Then, follow the instructions:
- Open System Preferences.
- Click on Security & Privacy, then go to the General tab.
- You’ll see the message “[App] was blocked from opening because it is not from an identified developer.” Clicking the button next to it marked “Open Anyway.”
- You’ll be asked again if you’re sure you’d like to run the app. Click the Open button to run it.
These steps allow you to open this app whenever you’d like. You should remember, though, that Gatekeeper won’t allow you to open apps that contain malware, even after following these steps.
Apple’s recommended way to open apps from an unidentified developer
Apple knows that Mac users still want to open apps from unidentified developers. Luckily, they’ve provided a method for doing so.
Here’s how:
- Go to your Mac’s Finder.
- Find the app you tried to open. If you’re having a hard time finding it, you can search for it in Finder or using Spotlight search (Command-Space).
- Right-click on the app.
- On the menu that pops up, click Open, and the app will open like any other.
Following these steps will make this app an exception, allowing you to open it again.
Opening apps from anywhere
Earlier versions of macOS used to provide the option to “allow apps from anywhere.” This would allow you to open any app without having to go through the above steps for each one you’d like to open.
While convenient, this can be dangerous, as it can leave your Mac open to malware. This is likely why it’s been hidden as a readily available option.
Are apps from unidentified developers safe?
Because they require circumventing Apple’s default security vetting process, it’s harder to determine whether apps from unidentified developers are safe. You’ll need to be sure yourself that a particular app can be trusted.
The best you can do to ensure that an app is safe to open is to do your research on it. Read through some reviews and look into the experiences other users have had with the app, as these sources are the most likely to give you truthful and relevant information. Dig as deeply as you can to help avoid downloading any dodgy apps.
You should also ensure that you have antivirus software (and that it’s up to date). This adds an extra layer of protection to your Mac. If you find that an app isn’t trustworthy, opt for an alternative app in the App Store or one from an unidentified developer that you can trust.

There are probably quite a few apps on your Mac that operate int he background, and spin up when you start your computer up. Those are startup (or login) items, and while they’re meant for convenience, some can be unruly.
It’s easy to see how there are apps that would benefit from running at startup. Calendars should be syncing in the background, and if you have a third-party app for managing the health of your computer, it should also be proactively starting up when you boot your computer.
Here, we’ll tell you how to manage startup programs Mac computers don’t need and tell you about a few ways to manage your system better.
What are Mac startup programs?
A startup program is an app that spins up when you start your computer. Instead of finding the app and clicking on an icon to activate it, your Mac tells the app when it’s turned on, and the app activates in the background.
Again, this is typically convenient, but some apps activate at startup when they don’t need to.
Types of startup programs
Most startup programs need to activate when you boot your Mac up. Here are some typical types of startup programs you likely won’t need to worry about:
User login items. Some apps need to activate when you login to your Mac. This may be for background sync, or for apps that need access to other apps while they run.
Launch agents. These are .txt files of apps that sit quietly in the background and help the app run once you start it up.
Application login items. These help applications start when your Mac boots up. You can’t delete these, but you can manage them.
Daemons. Like launch agents, daemons are little automated bits of an app that run in the background. The difference is while launch agents interact with apps, daemons are doing things on a system level.
Monitoring apps. Some apps spin up at login to keep an eye on your Mac’s performance and health.
How do I stop programs from opening on startup on my Mac
When you need to know how to stop programs from running at startup Mac hardware can be a bit tricky, but we’ve got yout covered. The absolute best way to make sure your Mac is running in tip-top shape is CleanMyMac X. It does a ton of work, and managing startup or login items for your Mac is one of many services it offers. While a routine, scheduled cleaning of your system is the best choice, CleanMyMac X also allows you granular control over startup or login items.
Here’s how to change startup programs Mac doesn’t need with CleanMyMac X:
- Open CleanMyMac X on your Mac
- On the left side of the window, select “Optimization”
Note: you can choose to clean up all login items and launch agents, or choose the individual processes you want to control. Because killing all startup programs can lead to unintended issues, we will tell you how to select individual startup programs to manage.
- In the main window, select one of two categories: Login Items, or Launch Agents
- On the right side of the window, select the items you would like to disable
- Select “Perform” at the bottom of the window
That’s all it takes to remove startup programs Mac can live without.
Remove programs manually
You can change startup programs Mac computers won’t always need manually, though it takes a bit of work. Here’s how to turn off startup programs Mac won’t use in System Preferences:
- On your Mac menu bar, select the Apple logo on the left side
- Select “System Preferences”
- Select “Users & Groups”
- Choose your ID from the list
Note: if you’re the only user on your Mac, you may only have one profile, and won’t need to choose a user from a list.
- Select “Login Items”
- Under the “Hide” column, un-select any items you no longer want to run at login
It takes a bit of doing, and the list may not have all items you’re looking for. This is part of the reason we prefer CleanMyMac X for this; it’s easier to use, and can manage all login items.
Manage startup programs on Mac from the Dock
Okay, we’ve told you how to disable login items – but what about apps that aren’t starting up at login? Can you get them to start when your Mac does?
Absolutely! This is a great option for apps that may be important to you, but aren’t spinning up at login. Chances are the apps you use most are already in your Mac’s dock, and that’s the best place to manage them as startup items. Here’s how:
- In your dock, right-click the app you want to open up at login
- Hover over “Options”
- Select “Open at Login”
Now, the app will spin up when you login to or start up your Mac. Keep in mind these apps won’t run in the background; instead, the app’s window will open at login. This is a great option for those with multiple profiles (one for personal and another for business, as an example) who need different apps for unique workflows.
If you find your Mac’s dock a bit intrusive or cumbersome, you may like uBar. A dock replacement for your Mac, uBar keeps things tucked out of the way, and shows you in a much better interface which apps are active and running on your Mac. It even has multiple-monitor support and status bars for apps running processes or downloading content.
Delay Mac startup apps
If you don’t want to disable startup items, you may instead want to know how to edit startup programs Mac doesn’t need immediately. An app named Delay Start can – well, delay the start – of apps at startup. Instead of an app activating immediately, you can set some to spin up on a delay. This is great if your Mac is booting up slowly, but you still need apps to run in the background throughout your day.
It’s a great app to keep in mind if you have a dedicated workflow. If you were a photo editor, you may want to delay the start of your photo editing software. If the first thing you do is import images from an external drive or camera, apps spinning up may interfere with the process. Rather than risk unintended consequences like lost images or damaged files, delaying an app’s start may be the better workaround.
Remove daemons and agents from startup process
You can check which daemons and agents are running on your Mac via the Finder app, but a word of caution: daemons and agents are hidden, which indicates you shouldn’t alter them unless you have a very clear understanding of the repercussions it may have. So, tread lightly.
Here’s how to remove agents and daemons via Finder:
- Open Finder on your Mac
- Select the main library on your Mac – it’s typically the username, and always has the house icon next to it
- Press Shift + Command + . (the period key on your Mac) to bring up hidden folders
- Select “Library”
- Select “Launch Agents” in the next column
This shows a full list of agents and daemons you can remove.
Conclusion
Managing launch services can really help make your Mac run faster, smoother, and eliminate unwanted services from spinning up. Some of the largest and most popular apps get a bad rap because they run at launch for no reason. Often, this is a means to make the app feel as though it is a critical part of your system; cloud storage services often run at startup to sync files, but the unintended consequence of them slowing your computer down may not be worth it.

Another great app to keep in mind is iStat Menus, an app that lives in your menu bar and keeps track of your CPU, memory, and GPU use. It’s one of those ‘good’ apps to run at startup because it monitors your entire system. If an app is running at startup and bogging your system down, iStat Menus will know about it.
