== Installation of ArcGIS on a Mac ==

-  Install Oracle VM Virtual-Box (VB) (I use version 3.2.8)
-  Create a virtual disk within the VB-Manager of at least 20 GB!
-  Create a "guest" within the VB-Manager, connect with your virtual disk under Storage (Massenspeicher) and include the CD/DVD-ROM
-  If there are more than one CPU-Kernels on your machine, you may designate on the VB-Manager under System more than one kernel for the "guest" and at least 2GB of memory!
-  Install Windows (I did XP) in the guest (choose boot-sequence in the VB-Manager), you may define in the VB-Manager also a common folder (Gemeinsamer Ordner) which is accessable from the host and the guest.
-  Start the guest '''ones''' in Safe-Mode (while boot, press F8) then install from the VB-Manager the Host-Extension (Geräte-Gasterweiterung installieren)
-  Do '''not''' activate the Display-options (Anzeige-Optionen) 3D or 2D-Video in the VB-Manager! You will not need it and ArcGIS does not like it!
-  Import all Updates, Servicepacks etc. (it will take several reboots and repeated Windows-Updates!)
-  Install .Net-Framework 3.5 SP1 incl. Updates (.Net-Framework 4 does not work with ArcGIS 10!) 
-  Mount the ArcGISDesktop...iso to the guest (select the appropriate *.iso under Storage (Massenspeicher))
-  Install ArcGIS as required.
-  Install the ArcGIS-License Manager with the license file.
-  Have fun
