Thanks Ashley for your report!

I've released FlightGear 1.9.1-r232, the latest package for FlightGear 1.9.1 (update for GUI Launcher and add-ons, not for simulator itself). I recommend all Mac FG users update the package.

This update contains the following bug-fixes and improvement to the GUI Launcher and add-ons:

Bug fixes from 1.9.1:

• Only mpserver02 was used regardless of a given server name
• Some options did not applied and their default values were used instead
[...]

I've released the FlightGear CVS binary package as of 2009-07-08 (r229).

The new feature on this release (for Mac OS X) is the Aircraft Preview. Thanks to fgviewer utility, it is really easy to see and tweak aircraft 3D models. You can try "Advanced Features" >> "Aircraft" >> "Preview" on the GUI launcher to preview the selected aircraft. On the preview window, you can tweak a model using keyboard and mouse. Pressing "h" key on the window will show you some brief instructions.

I've released the GUI launcher updater for 1.9.1, which is available from here.

The updater fixes the following issues:

1. FlightGear might not be invoked due to misconfiguration of FG_ROOT (data directory)
2. Some options like aircraft and airport are not properly parsed, and c172p and KSFO are used even though you specified other aircraft or airport.

Please install it from Advanced Features >> Others >> Install Add-ons from the GUI Launcher. And then restart FlightGear.app.

Here comes the binary package for FlightGear/CVS as of 2009-05-19. The main features in this release are:

• Model View
  • enables you to see other aircraft models on Multi Player servers.
• Wildfire integration (see Environment >> Wildfire settings from the menu)
• JSBSim update as of 2009-05-10

FlightGear 1.9.1 for Mac OS X has been released. This release is a bug-fix version of 1.9.0, and only binaries and the GUI launcher are updated. Therefore, the data and aircraft are the same as 1.9.0. You can download the package from Downloads page, as always. See below for further information on this update.

The bugs fixed in this releases includes:

• Black box showed up on some video card (Rarely happens on Macs)
• Possible segmentation fault while flying
• Some causes of possible NaN (Not a Number) errors while flying (that may freeze the simulator)
[...]

I've fixed some issues on the GUI launcher for 1.9.0. You can download the GUI updater from here.

This update is recommended for all FlightGear Mac OS X users. This update will fix the following issues:

• Fixed: archived aircraft couldn't be installed properly
• Fixed: some other minor bugs in installer (e.g. archived GUI-Updater was not installed properly)
• Fixed: FlightGear couldn't start if the path for FlightGear.app contains one or more white space.
[...]

I've reported that FlightGear may crash on Macs with nVidia Graphic cards due to likely driver bug in hardware mipmapping in a multi-thread environment. I've already introduced a workaround for this issue on 1.9.0 but it didn't cover all the nVidia drivers.

So I decided to disable hardware mipmapping on all nvidia drivers for avoiding annoying crash report.

How to update?

First, please read "Who needs to update" below and check if you need to update the framework. If you have never encounter a crash report while running FlightGear, you don't have to install this update. If you need this patch, then follow the instructions below:

1. Download osg.framework that includes a workaround for this issue.

We are very proud and excited to release the FlightGear 1.9.0 for Mac OS X. This release gives more fun and flexible flight to every single Mac user. It runs on both Mac OS 10.4 (Tiger) and 10.5 (Leopard). FlightGear 1.9.0 for Mac OS X comes with the fancy GUI launcher that eases your flight. You can change aircraft, airport, and options as you like.

The launcher also makes it possible to fly with your wing mates. Enabling multi-player mode pops up a fancy on-line map so you can find your new wing mates. Tail-to-nose flight can be more fun with fgcom, an integrated voice chat client. It allows you to chat with your wing mate for better communications including Voice ATC. Moreover, FlightGear Mac OS X finally integrates Atlas - the navitation map that helps your flight plan. Thanks to the easy installer in the launcher, you can add new aircraft, scenery, GUI updates, Nasal scripts, and any updates for existing files in a few seconds. Please consult ReadMe enclosed in the package for further information.

You can download FlightGear 1.9.0 from Downloads page, as always.

Have a happy flight, and a happy holiday!
