Changing the Security preferences for Mac OS X Snow Leopard is easy. You have options to use a firewall, enable the FileVault, and more. To access security preferences, open the System Preferences by clicking the gear icon on the dock and then choose the Security pane.
Change settings for HomePod Use the Home app on your iOS device or Mac to customize and manage settings for HomePod. With the Home app, you can customize settings for an individual HomePod and manage settings that apply to all of your HomePod speakers.
If you want to change the default app that opens a certain file type, you need to find a file that has the correct file type. So if you want all PNG files to open in a new app, you will need an PNG image to perform this.
The Settings app implements a hierarchical set of pages for navigating app preferences. The main page of the Settings app lists the system and third-party apps whose preferences can be customized. Selecting a third-party app takes the user to the preferences for that app. Every app with a Settings bundle has at least one page of preferences, referred to as the main page. If your app has only a few preferences, the main page may be the only one you need.
Settings here are divided into three tabs:
In other words, if you set the country to be “USA” or “Japan” on your iPhone for the App Store, that change will carry across to the Apple ID to your other devices using the same ID. That includes a Mac, iPad, iPhone, or whatever else you’re logged in with.
General: To add an extra layer of password security to a laptop (or a Mac in a public area), select the Require Password After Sleep or Screen Saver Begins check box. Snow Leopard then requires that you enter your login password before the system returns from a sleep state or exits a screen saver. Click the pop-up delay menu to specify when the password requirement will kick in (it’s immediate by default).
Admin-level users can set the global security features in the For All Accounts on This Computer section. You can choose to disable the automatic login feature, force Mac OS X to require a login password each time that a System Preference pane is opened, automatically log off any user after a certain amount of inactivity, or use a secure (encrypted) virtual memory on your hard drive. You can also mark the Disable Location Services check box to turn off the Location feature, preventing applications from using information based on your Mac’s current location.
If you don’t need the Remote on a regular basis, click the Disable Remote Control Infrared Receiver check box to select it. (But don’t forget to turn your IR receiver back on for your next movie night!)
FileVault: These controls allow you to set the master password for FileVault encryption within the current user’s Home folder, which makes it virtually impossible for others to access those files. Only an admin-level user can set the master password. After the master password is set, you can click the Turn On FileVault button to enable FileVault encryption for the user who’s currently logged in; the user’s Login password becomes his FileVault password as well.
Firewall: Mac OS X includes a built-in firewall, which you can enable from this pane.
To turn the firewall off entirely, simply click the Stop button. Any Mac hooked up to a network or the Internet should have the system firewall turned on.(The only exception is if you’re using a network that you know to be secure and your access to the Internet is through a router or sharing device with its own built-in firewall.)
When the firewall is enabled, click the Advanced button to set firewall options.
To turn the firewall on with only Mac OS X application exclusions, click Block All Incoming Connections.
To turn the firewall on with exclusions, click Automatically Allow Signed Software to Receive Incoming Connections. (This is the correct option for just about every Mac owner.) Any connection to a service (such as Web Sharing) or an application (such as iChat) that isn’t listed is blocked, but you can enable access for third-party applications as needed.
To add a third-party application to the Allowed list, click the Advanced button at the bottom of the Firewall pane; then click the button with the plus sign. Navigate to the application that needs to communicate with the outside world. Click the application to select it and then click Add.
To delete an application from the list, select it and click the button with the minus sign. Remember, you don’t have to add any of the applications provided by Apple with Snow Leopard, such as Apple Mail, iChat, and Safari; only third-party applications that you install yourself need a firewall rule.
You can edit the rule for a specific service or application by clicking the rule at the right side of the entry. By default, the rule reads Allow Incoming Connections (including both your local network and the Internet); however, when you click the rule, you can also choose Block Incoming Connections to temporarily deny access to that application.
If you suddenly can’t connect to other computers or share files that you originally could share, review the rules that you’ve enabled from this pane.
