I have a problem installing the MacTeX-2011-1.mpkg on my macbook (OS X 10.4.11). The first few steps (like Software License Agreement etc.) are working, but when it comes to the "proper" installation it fails:

The screen shot shows the problem: After choosing the volume to install onto, the installer asks whether I want to check some boxes (for example "Tex Live 2011" etc., (überspringen = engl. skip)). When I try to check the boxes nothing happens, they don't "take" the check. When I just press the button "installieren" (install) the box on the top appears. It says "You cannot continue. The software for the installation is missing". Does anyone know what to do?

Unfortunately, MacTeX 2011 cannot run on 10.4; the developers think that maintaining so many different versions (each requiring some adjustment when compiling executables) is too much of a labour. – egreg Nov 14 '11 at 21:16
Indeed, see the banner at tug.org/mactex/2011: "[ for Mac OS 10.5, 10.6, and 10.7 --- PPC and Intel ]" – Joseph Wright Nov 14 '11 at 21:18
Also, see tug.org/mactex/2011/faq/3-4.html – Joseph Wright Nov 14 '11 at 21:19
Thank you very much! Somehow I overlooked that peace of information. – Philip Nov 14 '11 at 21:24

MacTeX 2011 is for OS X 10.5 and higher.

This distribution requires Mac OS 10.5 Leopard or higher; see links below for Mac OS 10.3 or 10.4.

See the homepage for more information.

@all: Thank you very much. Now I installed the right version and it works. Juhu!!! – Philip Nov 14 '11 at 22:09
@Philip: Your welcome! I’m not sure if this works, but I guess with the TeX Live Utility (default installed at Macintosh HD/Applications/TeX//Macintosh HD/Programme/TeX/) you should be able to update at least the packages to the latest version. I hope that the newer packages work with the older programs (like pdflatex etc.). – Tobi Nov 14 '11 at 23:02
