I apologize if this has already been answered in these forums, but I haven't been able to locate any information pertaining to this problem. I have Leopard 10.5.4 installed and would like to update my graphics with the new patch. I'm getting this message when I try to install: You cannot install Leopard Graphics Update on this volume. This volume does not meet the requirements for this update. My system is as follows: 1.8ghz PowerPC G5 (Single Core) NVIDIA GeForce FX 5200 Mac OS X 10.5.4 Please help me out if you can! Thanks in advance.
