The only downside is that not all Windows apps can be converted especially the new ones as the developer takes some time to add support for them. Parallels Desktop. This is software which you can use to run.exe files on Mac computers. Parallels Desktop requires that you have a Mac computer with an Intel processor to be able to run the. The long ribbon of icons at the bottom of the Mac's screen is called the Dock. Clicking apps in the Dock is the primary method of launching them. The Dock also shows the status of applications—for example, whether they're running or needing your attention. Apple maintains a level of control over the apps you can install on your devices which protects your Mac from malware and bad user experience. This can be frustrating and worrying if you want to run an app and you are confronted by a warning that it is from an unidentified developer. There is an option to set apps to launch at startup on a Mac from the Dock menu in case the app you are looking to set in the startup is already present in the dock menu. But the Dock menu contains two types of apps. One is the fixed apps that are always present there and the other apps are presently running. However, the process is same for.
Note: This chapter describes property list keys specific to the macOS implementation of App Sandbox. They are not available in iOS.
In your macOS Xcode project, configure fine-grained security permissions by enabling settings in the Summary tab of the target editor. These settings, in turn, add Boolean values to entitlement keys in the target’s
.entitlements
property list file. The values are then incorporated into the target’s code signature when you build the project.You can think of using App Sandbox entitlements as a two-step process:
- Sandbox a target, which removes most capabilities for interacting with the system
- Restore capabilities to the sandboxed target, as needed, by configuring App Sandbox entitlements
At runtime, if a target requires a capability or a system resource for which the target isn’t entitled, the sandbox daemon (
sandboxd
) logs a violation message to the console.For more information about App Sandbox, read App Sandbox Design Guide.
App Sandbox Entitlement Keys
This section describes the keys you can use to confer capabilities to a sandboxed app in macOS. The first key enables App Sandbox; the others configure the sandbox. If App Sandbox is not enabled, the other keys in this section are meaningless.
The value to use for any of these keys is a Boolean
YES
or NO
, with the default value in each case being NO
. If you are editing the .entitlements
file directly in a text editor, the corresponding Boolean values to use are <true/>
and <false/>
. The default value for each key is false, so you can (and generally should) leave out the entitlement entirely rather than specifying a false value.https://brownwii126.weebly.com/utc-clock-app-mac.html. In cases where there are read-only and read/write entitlement key pairs, use of either key in the pair is mutually exclusive with the other.
Add these keys by using the Summary tab of the Xcode target editor. You can also add them directly to a target’s
.entitlements
file with the Xcode property list editor.For information on additional entitlements for handling special circumstances, see App Sandbox Temporary Exception Entitlements.
For each key in this table, providing a Boolean value of
YES
enables the corresponding capability (unless otherwise noted).Capability

Enabling App Sandbox
You enable App Sandbox individually for each target in an macOS Xcode project. For example, you may design a project as a main app, and some helpers in the form of XPC services. You then enable and configure the sandbox for each target individually.
To learn how to enable App Sandbox for your macOS app, which includes performing code signing, see App Sandbox Quick Start in App Sandbox Design Guide. The essential step is to ensure that the target editor checkbox named in Table 4-1 is selected.
Setting | Entitlement key |

Enable App Sandboxing | com.apple.security.app-sandbox |
Enabling User-Selected File Access
Xcode provides a pop-up menu, in the Summary tab of the target editor, with choices to enable read-only or read/write access to files and folders that the user explicitly selects. When you enable user-selected file access, you gain programmatic access to files and folders that the user opens using an
NSOpenPanel
object, and files the user saves using an NSSavePanel
object.Certain other user interactions, such as dragging items to your app or choosing items from the Open Recent menu, automatically expand your sandbox to include those items. Similarly, when macOS resumes an app after a reboot, the sandbox is automatically expanded to include any items that are automatically opened.
To enable user-selected file access in your app, use the Xcode target editor setting shown in Table 4-2.
Note: If your app needs to create executable files that are typically executed in some way other than through Launch Services (shell scripts, for example), you should also specify the
com.apple.security.files.user-selected.executable
entitlement.By default, when writing executable files in sandboxed apps, the files are quarantined. Gatekeeper prevents quarantined executable files and other similar files (shell scripts, web archives, and so on) from opening or executing unless the user explicitly launches them from Finder.
If those executables are tools that are intended to run from the command line, such as shell scripts, this presents a problem. With this flag, the file quarantine system allows the app to write non-quarantined executables so that Gatekeeper does not prevent them from executing.
This entitlement does not have an Xcode checkbox, and thus must be added to your app’s entitlement property list manually. For details, see App Sandbox Entitlement Keys.
Setting | Entitlement keys |
---|---|
User Selected File | com.apple.security.files.user-selected.read-only com.apple.security.files.user-selected.read-write |
Enabling Access to Files in Standard Locations
In addition to granting user-selected file access, you can employ entitlements to grant programmatic file access to the following user folders:
- Downloads
- Music
- Movies
- Pictures
The Xcode control for enabling Downloads folder access is a checkbox; the controls for enabling access to these other folders are pop-up menus.
When you enable programmatic access to the user’s Movies folder, you also gain access to their iTunes movies.
Reopening of files by macOS using Resume does not require the presence of any entitlement key.
To enable programmatic access to specific folders, use the Xcode target editor settings shown in Table 4-3.

Enabling Security-Scoped Bookmark and URL Access
If you want to provide your sandboxed app with persistent access to file system resources, you must enable security-scoped bookmark and URL access. Ambient sounds app mac os. Security-scoped bookmarks are available starting in macOS v10.7.3.
To add the
bookmarks.app-scope
or bookmarks.document-scope
entitlement, edit the target’s.entitlements
property list file using the Xcode property list editor. Use the entitlement keys shown in Table 4-4, depending on which type of access you want. Use a value of <true/>
for each entitlement you want to enable. You can enable either or both entitlements.For more information on security-scoped bookmarks, read Security-Scoped Bookmarks and Persistent Resource Access in App Sandbox Design Guide.
Entitlement key | Description |
---|---|
com.apple.security.files.bookmarks.app-scope | Enables use of app-scoped bookmarks and URLs |
com.apple.security.files.bookmarks.document-scope | Enables use of document-scoped bookmarks and URLs. Version note: in macOS v10.7.3, this entitlement key was named com.apple.security.files.bookmarks.collection-scope |
Enabling Network Access
Xcode’s Network checkboxes in the Summary tab of the target editor let you enable network access for your app.
To enable your app to connect to a server process running on another machine (or on the same machine), enable outgoing network connections.
To enable opening a network listening socket so that other computers can connect to your app, allow incoming network connections.
Note: Both outgoing and incoming connections can send and receive data. The sole difference is in whether your app is initiating the connection or is receiving connections initiated by other apps or other hosts.
To enable network access, use the Xcode target editor settings shown in Table 4-5.

Enabling Hardware Access
To allow a sandboxed target to access hardware services on a system—USB, printing, or the built-in camera and microphone—enable the corresponding setting in the Summary tab of the Xcode target editor.
- Camera access enables access to video and still image capture using the built-in camera, if available.
- Microphone access enables access to audio recording using the built-in microphone, if available.
- USB access enables the ability to interact with USB devices using USB device access APIs. On violation,
sandboxd
names the I/O Kit class your code tried to access. - Printing access is required if you want to provide a target with the ability to print.
To enable access to hardware, use the Xcode target editor settings shown in Table 4-6.
Setting | Entitlement key |
---|---|
Allow Camera Access | com.apple.security.device.camera |
Allow Microphone Access | com.apple.security.device.audio-input |
Allow USB Access | com.apple.security.device.usb |
Allow Printing | com.apple.security.print |
To allow access to hardware devices for which no checkbox exists in Xcode’s user interface, you must manually add the appropriate entitlement to your app’s entitlements property list. These additional entitlements are listed in Table 4-7. All of these keys take a Boolean value.
Entitlement key | Description |
---|---|
com.apple.security.device.audio-video-bridging | Interaction with AVB devices by using the Audio Video Bridging framework |

com.apple.security.device.serial | Interaction with serial devices |
Enabling Personal Information Access
A user’s personal information is inaccessible to your sandboxed app unless you grant access using the appropriate settings.
- Address Book access enables read/write access to contacts in the user’s address book.
- Location Services access enables use of the Core Location framework to determine the computer’s geographic position.
- Calendar access enables read/write access to the user’s calendars.
To enable access to personal information, use the Xcode target editor settings shown in Table 4-8.

Adding an App to an App Group
The
com.apple.security.application-groups
(available in macOS v10.7.5 and v10.8.3 and later) allows multiple apps produced by a single development team to share access to a special group container. This container is intended for content that is not user-facing, such as shared caches or databases.In addition, this attribute allows the apps within the group to share Mach and POSIX semaphores and to use certain other IPC mechanisms among the group’s members. For additional details and naming conventions, read “Mach IPC and POSIX Semaphores and Shared Memory” in App Sandbox Design Guide.
The value for this key must be of type
array
, and must contain one or more string
values, each of which must consist of your development team ID, followed by a period, followed by an arbitrary name chosen by your development team. For example:The group containers are automatically created or added into each app’s sandbox container as determined by the existence of these keys. The group containers are stored in
~/Library/Group Containers/<application-group-id>
, where <application-group-id>
is one of the strings from the array. Your app can obtain the path to the group containers by calling the containerURLForSecurityApplicationGroupIdentifier:
method of NSFileManager
.Enabling App Sandbox Inheritance
If your app employs a child process created with either the
posix_spawn
function or the NSTask
class, you can configure the child process to inherit the sandbox of its parent. However, using a child process does not provide the security afforded by using an XPC service.Important: XPC (as described in External Tools, XPC Services, and Privilege Separation) complements App Sandbox and is the preferred technology for implementing privilege separation in an macOS app. Before using a child process, consider using an XPC service instead.
To enable sandbox inheritance, a child target must use exactly two App Sandbox entitlement keys:
com.apple.security.app-sandbox
and com.apple.security.inherit
. If you specify any other App Sandbox entitlement, the system aborts the child process. You can, however, confer other capabilities to a child process by way of iCloud and notification entitlements.The main app in an Xcode project must never have a
YES
value for the inherit
entitlement.To add the
inherit
entitlement, edit the target’s .entitlements
property list file using the Xcode property list editor. Use the entitlement key shown in Table 4-9 with a value of <true/>
.Note: This property causes the child process to inherit only the static rights defined in the main app’s entitlements file, not any rights added to your sandbox after launch (such as PowerBox access to files).
If you need to provide access to files opened after launch, you must either pass the data to the helper or pass a bookmark to the child process. The bookmark need not be a security-scoped bookmark, but it can be, if desired.
If you are using other APIs to create child processes (such as
NSWorkspace
) and wish to have a shared container directory, you must use an app group.Entitlement key | Description |
---|---|
com.apple.security.inherit | Enables App Sandbox inheritance |
Enabling Scripting of Other Apps
If your app needs to control another scriptable app, your app can use the scripting targets entitlement to request access to one or more of the scriptable app’s scripting access groups.
Note: Before you can use this entitlement, the scriptable app must provide scripting access groups. If it does not, you can still control the app, but you use a temporary exception entitlement instead. In some cases, you may use both
scripting-targets
entitlement and a temporary entitlement together, to provide support across different versions of the OS. For more information, see Apple Event Temporary Exception. Pal iptv activation code free 2019. Entitlement key | Description |
---|---|
com.apple.security.scripting-targets | Ability to use specific AppleScript scripting access groups within a specific scriptable app |
The scripting target entitlement contains a dictionary where each entry has the target app’s code signing identifier as the key, and an array of scripting access groups as the value. Scripting access groups are identified by strings and are specific to an app. For example, the following entry would grant access to composing mail messages with Apple’s Mail app:

The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
View the app security settings on your Mac
By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”
Open a developer-signed or notarized app
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:
If you see a warning message and can’t install an app
If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
You may want to look for an updated version of the app in the App Store or look for an alternative app.
If macOS detects a malicious app
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
How to open an app that hasn’t been notarized or is from an unidentified developer
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.
The warning prompt reappears, and you can click Open.*
The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
Allow App To Run As Administrator Mac
*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.
