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.

After upgrading to macOS Catalina, follow these steps to turn on Voice Control: Choose Apple menu System Preferences, then click Accessibility. Click Voice Control in the sidebar. Select Enable Voice Control. When you turn on Voice Control for the first time, your Mac completes a one-time download from Apple. 2 Voice Control preferences.

Your Mac's hard drive probably has temporary files you don't need. These files often take up disk space for no good reason. Mac OS X tries to automatically remove temporary files, but a dedicated application will likely find more files to clean up.

Use these steps to enable the application firewall:

1. Choose System Preferences from the Apple menu.
2. Click Security or Security & Privacy.
3. Click the Firewall tab.
4. Unlock the pane by clicking the lock in the lower-left corner and enter the administrator username and password.
5. Click 'Turn On Firewall' or 'Start' to enable the firewall.
6. Click Advanced to customize the firewall configuration.

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:

1. Choose System Preferences from the Apple menu.
2. Click Security.
3. Click the Firewall tab.
4. Choose what mode you would like the firewall to use.

Advanced settings

Block 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:

• configd, which implements DHCP and other network configuration services
• mDNSResponder, which implements Bonjour
• racoon, which implements IPSec

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:

1. Open System Preferences.
2. Click the Security or Security & Privacy icon.
3. Select the Firewall tab.
4. Click the lock icon in the preference pane, then enter an administrator name and password.
5. Click the Firewall Options button
6. Click the Add Application (+) button.
7. Select the app you want to allow incoming connection privileges for.
8. Click Add.
9. Click OK.

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.

Mac Os Like Ubuntu

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.

Firewall 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.

Use Screen Time to see how much time you and your kids spend on apps, websites, and more. Then make informed decisions about how you use your devices, and set limits if you'd like to.

Follow these steps in macOS Catalina or later:

1. Choose Apple menu  > System Preferences, then click Screen Time.
   
2. Click Options in the lower-left corner.
3. Click Turn On.
4. To be able to see usage information for every other device signed in to iCloud with your Apple ID, select 'Share across devices' on each Mac. And on each iPhone, iPad, or iPod touch, go to Settings > Screen Time and turn on the same setting.

If you're using Family Sharing to manage a child account, you can turn on Screen Time directly from each of your child's devices. Or follow these steps to do it from your Mac:*

1. Choose Apple menu  > System Preferences, then click Family Sharing.
2. Click Screen Time in the sidebar, then select your child's name from the list on the right.
3. Click the Open Screen Time button to return to Screen Time preferences.

Before deciding whether to select 'Use a Screen Time Passcode,' learn about Screen Time passcodes.

Use a Screen Time passcode

Set a passcode so that only you can change Screen Time settings and allow more time when app limits expire. If you're a parent, use this feature to set up enforceable content, communication, and privacy limits for your child.

If you're using Family Sharing to manage a child account, follow these steps:*

1. Choose Apple menu  > System Preferences, then click Screen Time.
2. Choose your child's name from the menu in the upper-left corner.
3. Click Options in the lower-left corner.
4. Select 'Use Screen Time Passcode,' then enter a passcode when prompted.
5. If you're using the latest macOS, you're offered the option to enter your Apple ID to enable Screen Time passcode recovery, in case you forget your Screen Time passcode.

If you're not using Family Sharing to manage a child account, follow these steps:

In Time Like These Mac Os Catalina

1. Make sure that you're on the same Mac used by the child, and are logged in to the standard account used by the child. If you're not sure what to do, just continue with the steps below: Screen Time will help you.
2. Choose Apple menu  > System Preferences, then click Screen Time.
3. Set up Downtime, App Limits, Communication Limits, and Content & Privacy with all of the limits that you want for your child.
4. Click Options in the lower-left corner.
5. Select 'Use Screen Time Passcode,' then enter a passcode when prompted.
6. If you're using the latest macOS, iOS, or iPadOS, you're offered the option to enter your Apple ID to enable Screen Time passcode recovery, in case you forget your Screen Time passcode.

If you're setting a passcode while logged in to your administrator account, an alert explains that you should do this from a standard account. If you haven't set up a standard account for your child, you can either do that and log into their account, or choose from these options:

• Allow this user to administer this computer. If you choose this option, the passcode affects the current user, even though they're also an administrator of this Mac. This isn't recommended, because administrators have macOS privileges that could allow them to work around passcode restrictions.
• Don't allow this user to administer this computer. If you choose this option, you're prompted to enter your account password in order to modify your configuration. You're then guided through the steps to create a new administrator account—for use by the parent. The administrator account you're currently logged in to is converted to a standard account—for use by the child.
