64-bit macOS Test Client FAQ

What is the 64-bit macOS client?

It’s an alternative to the 32-bit client currently used to play Guild Wars 2 on macOS. Aside from technical implementation details and some game option availability, the two are functionally identical.

What does it mean that the client is 64-bit?

Modern computers generally have one of two types of processors: 32-bit, or 64-bit. 32-bit processors can only run 32-bit applications, while 64-bit processors can run both 32-bit and 64-bit applications. This new client is 64-bit, which means it’s intended to be run on a 64-bit processor (which every Mac released since 2008 uses).

What are the benefits over the 32-bit client?

64-bit applications have a significantly higher limit on how much memory they can use, which means significantly fewer “out of memory” crashes.

The 64-bit macOS client additionally has the benefit of being much easier for us to develop, debug, and improve upon. Stability issues and bugs that simply couldn’t be fixed in the 32-bit macOS client are much more likely to be fixable.

What is required to run the 64-bit client?

You need macOS 10.9 (Mavericks) or newer. This might change during the course of the test period.

How do I get the 64-bit client?

  1. Log in to arena.net and go to the Game Content page.
  2. Under Other Clients click the button labelled macOS Test Client Download 64-bit Application to download the client.
  3. Open the downloaded file and drag the Guild Wars 2 64-bit icon to your Applications
  4. You can then launch the client by opening the app in the Applications

I already have the 32-bit client. Will I have to completely re-download the game to switch to the 64-bit client?

No. The 64-bit client uses the same data as the 32-bit client. If you already have the 32-bit client in the Applications folder, you don't have to do anything special to make the 64-bit client use the same data. Upon launch, it will find the existing data instead of downloading it from scratch.

Note that this is only true if the 32-bit client was installed before the 64-bit client (and not removed). If you at any point remove the 32-bit client, the 64-bit client will start downloading game content from scratch. This will only be necessary while the 64-bit client is in testing.

Are the two clients mutually exclusive?

No. You may have both clients installed and use either one as you see fit.

Are there any performance differences between the 64-bit and 32-bit client?

The two clients use significantly different technologies, and are likely to differ in both performance and stability. Currently the 64-bit client may be somewhat behind in performance on some computers, but it should be significantly more stable. We’re actively working on improving performance.

Do I have to hold the Fn-key to be able to use the function keys for key bindings?

The function keys provide system functions by default when not holding the Fn-key, such as changing screen brightness or speaker volume. That means Guild Wars 2 won’t recognize them unless you’re also holding the Fn-key. If you would prefer to swap this functionality so that pressing the function keys alone instead provides program actions and holding the Fn-key is required for system actions, you can do so in the macOS system preferences:

  1. Open system preferences by clicking the Apple logo in the menu bar.
  2. Click System Preferences
  3. From there, click Keyboard and check the checkbox labelled Use F1, F2, etc. keys as standard function keys. You may then close the window.

What graphics API does the 64-bit macOS client use?

The 64-bit macOS client uses OpenGL.
