Change permissions for files, folders or disks on Mac

Permission settings determine who can view and alter files on the computer. You change permission settings at the bottom of the Info window for a file, folder or disk in the Finder. For example, you can change permission settings for a folder so that other users who log in to your Mac, or connect to it for file sharing, can view but not change files in a folder.

Assign permissions to users and groups

On your Mac, select a disk, folder or file, then choose File > Get Info.

If the information in Sharing & Permissions isn’t visible, click the arrow .

If the lock at the bottom right is locked , click it to unlock the Get Info options, then enter an administrator name and password.

Click a user or group in the Name column, then choose a privilege setting from the pop-up menu.

Read & Write: Allows a user to open the item and change it.

Read only: Allows a user to open the item but not change its contents.

Write only (Drop Box): Makes a folder into a drop box. Users can copy items to the drop box, but can’t open it. Only the owner of the drop box can open it.

No Access: Blocks all access to the item.

You can undo any changes to privilege settings for a user or group in the Sharing & Permissions section since opening the Info window. Before closing the Info window, click the Action pop-up menu , then choose “Revert changes”.

Apply permissions to all items in a folder or a disk

On your Mac, select a folder or disk, then choose File > Get Info.

If the lock at the bottom right is locked , click it to unlock the Get Info options, then enter an administrator name and password.

Click the Action pop-up menu , then choose “Apply to enclosed items”.

Change an item’s owner

On your Mac, select the item, then choose File > Get Info.

If the lock at the bottom right is locked , click it to unlock the Get Info options, then enter an administrator name and password.

If the new owner’s name isn’t listed in the Name column in the Sharing & Permissions section, click the Add button to add the new owner.

Select the new owner in the Name column, click the Action pop-up menu , then choose “Make __ the owner”.

You can undo any changes to an item’s owner in the Sharing & Permissions section since opening the Info window. Before closing the Info window, click the Action pop-up menu , then choose “Revert changes”.

Add or remove a user or group in the Name column

On your Mac, select an item, then choose File > Get Info.

Change File Permissions in Mac OS X

You can instantly change file permissions in Mac OS X without getting your hands dirty in the command line by using the Finder instead. All you need to do is access the “Get Info” panel for the file, folder, or application in question. These instructions demonstrate locating the file permissions manager, and how to adjust privileges for items found in Mac OS.

It’s worth mentioning that you can also use this trick to quickly view current file and folder permissions and ownership details in the Mac OS X Finder. To view permissions, just use the Get Info panel as described below but don’t make any modifications. Mac OS X calls permissions “Privileges”, but they mean the same thing.

How to Change File Permissions on Mac

This is the most user friendly way to view or adjust file permissions in Mac OS X, it works with anything found in the Finder file system, be it a file, binary, application, or a folder. Here’s what you’ll want to do:

1. Select the file or app in the Finder you want to edit permissions for
2. Hit Command+i to “Get Info” about the selected file (or go to File > Get Info)
3. At the bottom of the Get Info window, you’ll see “Sharing & Permissions”, select the arrow to drop down the options
4. Adjust permissions* on a per user basis, the options being: read and write, read only, or no access

*Note that with certain files, apps, and folders, you may need to click on the little lock icon in the corner of the Get Info window, this will require a login to grant access from the administrator to be able to modify the permissions for the selected item.

When finished, just close out of the Get Info window. The changes to permissions happen immediately as you select items from the privilege option dropdown menus.

Permission Types & Explanations of Limitations

The permissions options are fairly self-descriptive in their naming, but here’s a quick overview in case you’re new to the concepts on a file level:

• Read & Write: The user can both read the file, and write to the file (make changes, modify the file, delete it, etc)
• Read Only: The user can only read the file, and is therefor unable to make changes to the file
• No Access: The user has no access to the file at all, meaning the user can not read the file or write to it

When you’re finished setting the desired permissions and privileges, close the Get Info window and the changes will take effect immediately.

Notice that you can’t make files executable through this the Get Info panels, you’ll still need to pull up the terminal for that.

One of our readers pointed out that you can use Get Info to adjust file permissions on remote files using the Mac OS X built-in FTP client, which is pretty convenient if you’re without a separate FTP app but you’re remotely needing to change privileges on something.

Generally speaking, if you’re not sure what to set, you shouldn’t mess around with file permissions since it can change the way a file or application responds to a given document. This is particularly true with system files and applications, as permissions can mean the difference between some apps working and some not. If you’re digging around because of frequent errors regarding access to files or ownership, try using the Recovery Mode method of repairing user permissions that works with Mac OS X 10.7, 10.8, 10.9, 10.10, macOS 10.12, 10.11, 10.13, etc, which can usually sort out those problems automatically without any manual modification of files.

You can also modify permissions from the command line using the ‘chmod’ command followed by flags or sequences and a file name, but that’s really a topic for another article.

Do all Mac OS X applications require Admin permissions to ‘install’?

I’m new to the whole Mac OS X operating system. I’m trying to learn and I’ve got myself a MacBook running Mac OS X 10.7.3.

I’ve created a test user that can not administrate so that I can test out permissions and I’ve found that I can not do anything in the Applications folder, which includes ‘installing’ applications (even those drag ‘n’ drop ones) and creating folders, without entering an Admin name and password.

However, I was under the impression that this wasn’t the case and you only needed Admin permissions to write to somewhere like Preferences, so can somebody please clarify why it is asking for Admin when I try to drag ‘n’ drop applications into the Applications folder.

It depends on which Applications folder you mean. In fact, there can be two:

This one is owned by root , and reserved for all applications that already come with OS X, like Mail.app, iTunes.app, etc. This root user is not an account you can log into with the graphical interface, but it’s still accessible via Terminal.

Since the folder requires your user to be in the admin Unix group, you can’t just drag and drop files there unless you actually have an admin account (enabling this in System Preferences will add your user to this admin group). You can check the groups your user belongs to by typing id -Gn in a Terminal.

This one might not even exist in your system, but you can easily create it by opening Finder, clicking Go → Home, then File → New Folder, and naming it «Applications».

As this folder resides in your home folder, it belongs to you only. So if you need to drag-and-drop an application to install it, put it there instead of /Applications . You don’t need admin privileges here.

How to change permissions on Mac and keep your data private

Every item on your Mac, whether it’s a file or folder, has a set of permissions. Those determine who can view and modify data on your computer. If at some point you need to restrict access to some of your files, you can easily do that by changing permissions.

In this article, we’ll show you how to view and change file permissions, as well as how to stay in control of your application permissions. Let’s start!

What permission types are on Mac?

There are several types of permissions users can have on macOS:

• Read only — Allows a user to open the file, but not change it.
• Write only — Makes a folder into a drop box. A user can copy items to the drop box, but cannot open it. Only the owner of the drop box can open it.
• Read & Write — Allows a user to open the file and change it.
• No Access — Blocks access to the file.

How to view file permissions

Any user can view the file permissions using the Finder’s Info window. In Finder, right-click the file or folder and choose Get Info from the menu. Click the Sharing & Permissions triangle to see the item permissions.

How to change permissions for files, folders, or disks

The next step is to actually change the item permissions to whatever you want. Below are a few examples of how you can adjust permissions to your needs.

Assign permissions to users and groups

1. On your Mac, choose a file or folder.
2. Right-click it and select Get info.
3. Click the disclosure triangle in the Sharing & Permissions block.
4. Click the lock icon to unlock it.
5. Enter the administrator name and password.
6. Choose the user in the Name column and then choose Privilege setting from the pop-up menu.

Apply permissions to all files in a folder/disk

1. Choose a folder or disk.
2. Select File > Get Info.
3. Click the lock icon to unlock it.
4. Enter the administrator password.
5. Click the Action pop-up menu and choose Apply to enclosed items.

Change a file’s owner

1. On your Mac, choose the file.
2. Click the lock icon to unlock it.
3. Enter the administrator password.
4. If the new owner’s name is not listed in the Name column in the Sharing & Permissions block, click the Add button to add the new owner.
5. Choose the new owner in the Name column, click the Action pop-up menu, then choose Make_the owner.

How to control application permissions

The latest macOS versions introduced new security controls. Now apps have to request permission before accessing certain parts of your drive. For example, if you open Skype for the first time, you’ll get a pop-up asking permission to access your camera and microphone.

You can easily check what programs are allowed to use your webcam, microphone, files and folders. There are two ways to do that — via System Preferences or using a third-party app like CleanMyMac X.

Change app permissions via System Preferences

If you have a strange feeling that someone is watching or listening to you, you can check what apps have access to your camera or microphone. Here’s how to do that:

1. Go to the Apple menu.
2. Choose System Preferences > Security & Privacy.
3. Select the Privacy tab.
4. Choose Camera from the left menu.
5. Check what apps are allowed to use your camera.
6. Uncheck the box next to the apps you don’t want have access to your camera.

Note:

You can limit access to your camera or microphone only for third-party apps. Apple apps and bundled system apps will not show up in the camera access control list. So, for example, you won’t see FaceTime in the app permissions panel.

Control all permissions easily with CleanMyMac X

If you don’t feel like browsing your System Preferences in search of app permissions, there is an easier and faster way to manage them. Get yourself the app CleanMyMac X and use its freshly-baked feature “Application Permissions.” You’ll be able to view and manage all permissions from one place, in a matter of seconds.

Here’s how it works:

1. Download and install CleanMyMac X (it has a free trial version)
2. Launch the app.
3. Go to the Privacy module.
4. Click Scan.
5. Choose Application Permissions.
6. Check your permissions and adjust the ones you want.

As simple as that!

As long as you’ve already installed CleanMyMac X, we recommend you trying its other tools. Start from Smart Scan — a one-button solution for checking your Mac for unneeded junk files, viruses, and suitable speedup tasks.

That’s it. Now you know everything about permissions on your Mac and can adjust the settings to your personal needs. May your personal data be always safe and untouched!
