OS X v10.5.1 and later include an application firewall you can use to control connections on a per-application basis (rather than a per-port basis). This makes it easier to gain the benefits of firewall protection, and helps prevent undesirable apps from taking control of network ports open for legitimate apps.
Go to the Security & Privacy settings area. At the bottom of the screen, under the General tab, you will see your ‘Allow apps downloaded from’ setting. If you have ‘App Store’ (only) checked, that may be your problem, and you can change it to ‘App Store and identified developers’. To open an unsigned app, you need to right-click or Control-click the app and select “Open”. This works on macOS Sierra as well as previous versions of macOS. You’ll be warned that the app is from an unidentified developer–in other words, it isn’t signed with a valid developer signature. If you trust the app, click “Open” to run it. Apps that will be killed off in macOS Catalina include Transmist 4.1.7, 1Password 2.12.2, iStats Menu 2.9 and QuickBooks 2015. You can view the full list of the apps at The Tape Drive. Use Timed Access Control to restrict when devices can connect to your Apple base station Wi-Fi Your AirPort Extreme and Time Capsule router can block certain devices at certain times of day, based. For apps that control their startup behavior from within the app, you’ll want to visit the app directly. Look for an item in the app’s preferences about starting at login. Uncheck that box, and the app will not run at login in the future.
Configuring the application firewall in OS X v10.6 and later
Use these steps to enable the application firewall:
Configuring the Application Firewall in Mac OS X v10.5
Make sure you have updated to Mac OS X v10.5.1 or later. Then, use these steps to enable the application firewall:
Advanced settingsBlock all incoming connections
Selecting the option to 'Block all incoming connections' prevents all sharing services, such as File Sharing and Screen Sharing from receiving incoming connections. The system services that are still allowed to receive incoming connections are:
To use sharing services, make sure 'Block all incoming connections' is deselected.
Allowing specific applications
To allow a specific app to receive incoming connections, add it using Firewall Options:
Macos Allow Apps Below To Control Computer Unchecked Boxes
Mac app that lets you draw on photos. You can also remove any apps listed here that you no longer want to allow by clicking the Remove App (-) button.
Automatically allow signed software to receive incoming connections
Applications that are signed by a valid certificate authority are automatically added to the list of allowed apps, rather than prompting the user to authorize them. Apps included in OS X are signed by Apple and are allowed to receive incoming connections when this setting is enabled. For example, since iTunes is already signed by Apple, it is automatically allowed to receive incoming connections through the firewall.
If you run an unsigned app that is not listed in the firewall list, a dialog appears with options to Allow or Deny connections for the app. If you choose Allow, OS X signs the application and automatically adds it to the firewall list. If you choose Deny, OS X adds it to the list but denies incoming connections intended for this app.
If you want to deny a digitally signed application, you should first add it to the list and then explicitly deny it.
Some apps check their own integrity when they are opened without using code signing. If the firewall recognizes such an app it doesn't sign it. Instead, it the 'Allow or Deny' dialog appears every time the app is opened. This can be avoided by upgrading to a version of the app that is signed by its developer.
Enable stealth mode
Enabling stealth mode prevents the computer from responding to probing requests. The computer still answers incoming requests for authorized apps. Unexpected requests, such as ICMP (ping) are ignored.
Macos Allow Apps Below To Control Computer Unchecked Box SymbolFirewall limitations
The application firewall is designed to work with Internet protocols most commonly used by applications – TCP and UDP. Firewall settings do not affect AppleTalk connections. The firewall may be set to block incoming ICMP 'pings' by enabling Stealth Mode in Advanced Settings. Earlier ipfw technology is still accessible from the command line (in Terminal) and the application firewall does not overrule any rules set using ipfw. If ipfw blocks an incoming packet, the application firewall does not process it.
Systems Manager can be used to deploy apps to all of your managed devices through the Systems Manager > Manage > Apps page. The Meraki Dashboard integrates directly with Google Play and both the iOS and macOS App Stores, which allows you to quickly and easily configure and deploy apps to your mobile devices.
For information on deploying custom software from installer files for Windows and Mac devices, see this article. For deploying custom enterprise apps for iOS and Android, see this article.
Initial Setup
To deploy Android apps, you will first need an Android Enterprise domain, either Google or Meraki-managed, bound to your Meraki Dashboard.
To deploy iOS or macOS apps, you will first need your APNs token set up to enable communications with Apple's servers. To push out apps silently to devices, and avoid prompting the end user to sign into an Apple ID or to push apps to macOS at all, you will need to set up your Apple Volume Purchase Program (VPP) account as well, which allows you to centrally manage application licenses. See more info on silent iOS app installs here.
Adding Store Apps
Once you are ready to add your apps, navigate to Systems Manager > Manage > Apps and select 'Add new' at the top right of the page, and iOS/macOS app store, or Android Play Store app.
Search for your application, and click the app entry found to enter the app configuration page. In this example, we show adding an iOS app, but the steps are the same for macOS.
Note: Dashboard does not allow the adding of multiple apps with the same app identifier (i.e. com.carrotcreative.Ham-Horn in the above image). To check which app identifiers have already been added, navigate to the Systems Manager > Manage > Apps page, click on the wrench icon on the right, and add the 'Identifier' column.
Configuring Apps
After adding an app, you'll see an interface similar to the below. Note that Android apps may show slightly different options until changes are saved.
Scope
By default, this app will be pushed down to all devices of the matching operating system, but this can be narrowed down by tag. See tag scoping for more info.
License Method (iOS only)
This is used to specify if an iOS app should be configured to use one of your organizations VPP licenses, instead of prompting the user to sign into their Apple ID. You may use the drop down to select either VPP Codes, VPP User Assignment, or VPP Device Assignment. For more information about VPP, see our article here.
macOS App Store App deployment requires the use of VPP Device Assignment, and as such is always selected for this type of app.
Auto-Install / Auto-Uninstall
By default, apps will automatically attempt to install on all scoped devices once 'Save Changes' is clicked. To push out an install later, or leave the installation option up to the end user, who can access available apps through the managed Play Store or Systems Manager app, uncheck this option.
Remove with MDM
Selecting this check-box will force the app to be uninstalled when the Meraki management profile is uninstalled. This is important to have checked if you want to ensure that the apps you select are only available to those mobile devices that are managed by Systems Manager. https://treeyoo698.weebly.com/blog/bitcoin-trading-app-mac.
macOS App Store Apps cannot be removed by unscoping the app or this 'remove with MDM' option. To remove macOS App Store Apps the device will need to send a command to remove the app locally such as
sudo rm -r '/Application/AppName' or deploy a script / custom .pkg to do this.
Attempt to Manage Unmanaged (iOS only)
If the device you push this application to is already installed, Systems Manager will attempt to take management over the app, allowing Dashboard admins to push updates and uninstalls for that app. This is only available on iOS 9+, and will prompt the user for confirmation on unsupervised devices.
Backup on Sync (iOS only)
Deselecting this check-box will prevent app-generated data from being backed-up during a sync. This is important for administrators who want to separate personal from organizational/corporate data on an iOS device.
Approval Status (Android)
After saving changes initially, the option to approve the app for your managed Play Store will appear. Users will not be able to access the app for download until you approve it first. See our deployment guide for more info.
Pushing and Updating Apps
After configuring your app, clicking on 'save changes' will automatically push out the app install commands to devices in scope, listed at the bottom of the page. Again, ensure you have VPP app licenses available for iOS apps if applicable, and that you have approved Android apps for end users to access.
To manually re-push apps, you can use the commands under 'Status' to re-push to all scoped devices, or only devices missing the app. You can also selectively re-push the app to specific devices by checking the boxes at the bottom and clicking Manage > Update/Reinstall. This can be used to manually update apps that have new versions available in the app store as well.
For more information on pushing app updates, see this article.
