Hi dale, follow the instructions below:

- Before installing the main program and patch on Mac OSX, users must have Administrator rights on the computer. To set Administrator rights in the Mac OS follow these steps:
1) From the Apple Menu select “System Preferences...”
2) Click the “Users” icon
3) Double-click on the user’s name to edit the user’s settings
4) Click the “Password” tab
5) Check the “Allow user to administer this computer” box. Disable any "guest" account.
6) Click “OK” Log out and Log back in (from the Apple menu) to make the changes take effect.
Note Only a user with administration privileges can make the changes listed above.

- To install the main program, do not run (double click) the application from the disk image. Instead copy the folder AeroFly Professional Deluxe to any place you like (the preferred place
for AeroFly Professional Deluxe on Mac OS X is the User application folder ~/Applications) or the desktop.
1) After inserting the DVD, the DVD symbol afpd-mac will appear on your desktop.
2) Double clicking on the symbol will show the content of the DVD.
3) Pull the dmg-file from the folder to the desktop
4) Double click on the dmg-file, which you just had copied
5) Accept the license conditions and wait while the system is checking the installation files
6) After a few minutes the dmg will open and you will see a new finder window.
7) Now pull the Aerofly Professional Deluxe folder from the finder window onto the desktop
8) Double click on the Aerofly Professional Deluxe folder, which is on the desktop.
9) To start the simulation double click on Aerofly
10) As a last step you may delete the finder window and the afpd-vxxxxxx.dmg files, which are no longer necessary.

- To install the patch, unzip (double click) on the downloaded file and copy or drag the extracted Aerofly.app file into your AeroFly Professional Deluxe directory.
- ATI and Nvidia video card drivers are automatically delivered with a Mac OS X update. So, there's no need for a separate download and installation
