By clicking this icon on the respective product page, transferring the software onto your computer will start.

After the software package has been successfully transferred to your computer, it will appear as a .dmg.gz file in your download folder.

After Mac OS X has unpacked this file, you will get a DMG file.

The Finder handles the DMG file as a small drive containing the software.

After the software has been copied from this drive to your computer, you can eject the drive. Its icon will disappear.

How to Download Software Packages

Our software products for the Mac OS X platform are distributed electronically. You can transfer a software package via Internet to your computer and work with the new program immediately. The user manual is at your service via the Help Viewer of Mac OS X. Updating the software, or sending us feedback and inquiries is also a matter of a few mouse clicks only, and can be managed directly in the application. Long-winded tinkering with software disks, books and packages is a thing of the past.

Using Safari for download in a default configuration of Mac OS X

If you are using Safari to download the software, and you have left Safari in its default setting, Mac OS X will handle all steps automatically for you:

1. Click on the text Begin download on our Internet page for the respective product. Safari will transfer the software package to your computer.
2. Safari opens and unpacks the package. A "virtual disk drive" will be displayed on your computer, as if you had inserted a CD or floppy disk. This drive contains the software. In addition, the End User License Agreement will be displayed on your screen.
3. After you have accepted the License Agreement by pressing the button Agree, you can use the Finder to copy all software components into a folder on your computer. In most cases that's all. A complicated "installation" is usually not necessary. If it should be necessary in a special case nonetheless, the respective instructions will be displayed in the Finder window of the disk drive.
4. After you have copied the software onto your computer, you can eject the drive.

Manual download step by step

If you have instructed Safari not to automatically activate all downloaded material (this is recommended for security reasons), or if you are using a different web browser, you'll have to unpack the software package manually. But this is also a matter of a few easy steps only:

1. Click on the text Begin download on our Internet page for the respective product. Safari will transfer the software package to your computer.
2. The package is a file with the extension ".dmg.gz". It will be located in the download folder of your web browser after the download has been completed successfully. In most browsers, the download folder is preconfigured to be your private Desktop folder. In this case, the downloaded file will automatically appear on your Desktop background. If you have configured your browser differently, you could also use any other folder.
3. Open the ".dmg.gz" file now by double-clicking it. Mac OS X should automatically unpack the file and create a ".dmg" file as a result. If this does not happen, please see the instructions below.
4. Now open the ".dmg" file by double-clicking it. This causes the End User License Agreement to be displayed. If you agree with the conditions, press the button Agree. The Finder will display a "virtual disk drive" which contains the software. If this does not happen, please see the instructions below.
5. Use the Finder to copy the software components to the desired folder on your computer. The disk drive might show further instructions what to do exactly.
6. After all necessary parts have been copied over, you can eject the drive.

How to I eject the drive containing the software?

The disk drive containg the software behaves like a normal disk drive of Mac OS X. Please make sure that all running tasks have been finished before ejecting the drive. If you have mistakenly launched an application directly from the drive for example, please quit this application first. To eject the drive, you can use any of the following steps:

• Click on the icon of the disk drive and select the menu item File > Eject "Name of Software" in the Finder.
• Drag the icon of the disk drive onto the Trash. The Trash will change into an eject symbol while you are doing this.
• If you are using Mac OS X Panther or a later version of Mac OS X, you can also click onto the small eject symbol next to the icon of the disk drive in the side-bar of the Finder.

After that, the icon of the disk drive will disappear.

When unpacking the GZ file doesn't work

If unpacking the GZ file does not work as expected, your personal preferences for opening GZ files might have been altered, or there is a technical problem with your unarchiver program. Please try to solve the problem as follows:

1. Click onto the file with the ".dmg.gz" extension. Keep the ctrl key pressed and hold down the mouse button until a context menu appears.
2. Go to the menu item Open with and select the application that should be used to unpack the file. In older versions of Mac OS X this should be the application StuffIt Expander. In all newer versions of Mac OS X it is recommended to use the application BOMArchiveHelper.

After this, the selected application should launch and create a DMG file. If the program displays an error message that the GZ file is damaged, something went wrong during the download. In this case, please repeat the download with your web browser.

When opening the DMG file doesn't work

If opening the DMG file does not work as expected, your personal preferences for this file type might have been altered, or there is a technical problem with your Mac OS X system. Please try to solve the problem as follows:

1. Click onto the file with the ".dmg" extension. Keep the ctrl key pressed and hold down the mouse button until a context menu appears.
2. Go to the menu item Open with and select the application that should be used to open the file. In older versions of Mac OS X this should be the application Disk Copy. In all newer versions of Mac OS X, however, it is recommended to use DiskImageMounter.

If you are getting an error message that the drive does not contain a usable partition or that error "-95" has occurred, your system is affected by a technical problem. Unfortunately, some versions of Mac OS X contain a defect which causes this problem. Please try the following to solve the problem:

1. Launch Disk Utility from the folder Utilities, select the volume that contains your Mac OS X system and press the button Repair permissions.
2. When the repair procedure has finished, restart the computer.
3. Try again to open the DMG file.

Cleaning up after having copied the software

After you have successfully copied the software from the displayed disk drive onto your computer, you can decide what you will do with the downloaded ".dmg.gz" file and the unpacked ".dmg" file.

If you have multiple computers or want to archive the package, you might want to copy the GZ file onto another computer, or move it into an archive folder, respectively. The DMG file can be dragged into the Trash in any case.

If you no longer need the downloaded package, you can drag both the ".dmg.gz" file, as well as the ".dmg" file into the Trash.

In both cases you'll have to make sure first that the disk drive has been ejected as mentioned above.
