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.

Configuring the application firewall in OS X v10.6 and later

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.

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.

The Mac has plenty of games, but it'll always get the short end of the stick compared to Windows. If you want to play the latest games on your Mac, you have no choice but to install Windows ... or do you?

There are a few ways you can play Windows games on your Mac without having to dedicate a partition to Boot Camp or giving away vast amounts of hard drive space to a virtual machine app like VMWare Fusion or Parallels Desktop. Here are a few other options for playing Windows games on your Mac without the hassle or expense of having to install Windows.

GeForce Now

PC gaming on Mac? Yes you can, thanks to Nvidia's GeForce Now. The service allows users to play PC games from Steam or Battle.net on macOS devices. Better still, the graphic power of these games resides on Nvidia's servers. The biggest drawback: the service remains in beta, and there's been no announcement when the first full release is coming or what a monthly subscription will cost.

For now, at least, the service is free to try and enjoy. All supported GeForce NOW titles work on Macs, and yes, there are plenty of them already available!

The Wine Project

The Mac isn't the only computer whose users have wanted to run software designed for Windows. More than 20 years ago, a project was started to enable Windows software to work on POSIX-compliant operating systems like Linux. It's called The Wine Project, and the effort continues to this day. OS X is POSIX-compliant, too (it's Unix underneath all of Apple's gleam, after all), so Wine will run on the Mac also.

Wine is a recursive acronym that stands for Wine Is Not an Emulator. It's been around the Unix world for a very long time, and because OS X is a Unix-based operating system, it works on the Mac too.

As the name suggests, Wine isn't an emulator. The easiest way to think about it is as a compatibility layer that translates Windows Application Programming Interface (API) calls into something that the Mac can understand. So when a game says 'draw a square on the screen,' the Mac does what it's told.

You can use straight-up Wine if you're technically minded. It isn't for the faint of heart, although there are instructions online, and some kind souls have set up tutorials, which you can find using Google. Wine doesn't work with all games, so your best bet is for you to start searching for which games you'd like to play and whether anyone has instructions to get it working on the Mac using Wine.

Note: At the time of this writing, The Wine Project does not support macOS 10.15 Catalina.

CrossOver Mac

CodeWeavers took some of the sting out of Wine by making a Wine-derived app called CrossOver Mac. CrossOver Mac is Wine with specialized Mac support. Like Wine, it's a Windows compatibility layer for the Mac that enables some games to run.

CodeWeavers has modified the source code to Wine, made some improvements to configuration to make it easier, and provided support for their product, so you shouldn't be out in the cold if you have trouble getting things to run.

My experience with CrossOver — like Wine — is somewhat hit or miss. Its list of actual supported games is pretty small. Many other unsupported games do, in fact work — the CrossOver community has many notes about what to do or how to get them to work, which are referenced by the installation program. Still, if you're more comfortable with an app that's supported by a company, CrossOver may be worth a try. What's more, a free trial is available for download, so you won't be on the hook to pay anything to give it a shot.

Boxer

If you're an old-school gamer and have a hankering to play DOS-based PC games on your Mac, you may have good luck with Boxer. Boxer is a straight-up emulator designed especially for the Mac, which makes it possible to run DOS games without having to do any configuring, installing extra software, or messing around in the Mac Terminal app.

With Boxer, you can drag and drop CD-ROMs (or disk images) from the DOS games you'd like to play. It also wraps them into self-contained 'game boxes' to make them easy to play in the future and gives you a clean interface to find the games you have installed.

Boxer is built using DOSBox, a DOS emulation project that gets a lot of use over at GOG.com, a commercial game download service that houses hundreds of older PC games that work with the Mac. So if you've ever downloaded a GOG.com game that works using DOSBox, you'll have a basic idea of what to expect.

Some final thoughts

In the end, programs like the ones listed above aren't the most reliable way to play Windows games on your Mac, but they do give you an option.

Of course, another option is to run Windows on your Mac, via BootCamp or a virtual machine, which takes a little know-how and a lot of memory space on your Mac's hard drive.
