Update 22apr07: Hex offsets for MDD dual 867MHz now available
Ok, things haven’t changed much for machines close to the minimum spec since 1.5.2, so for my 1GHz 12″ PowerBook all I need to edit is the Info.plist file inside the Aperture.app/Contents directory. I changed both the minimum RAM and minimum CPU requirements down to 500MB and 1GHz:
<key>AELMinimumRAMSize</key>
<string>500</string>
and:
<key>RKG4LaptopMinimumCPUSpeedMHz</key>
<integer>1000</integer>
Edit those entries with either a text editor, or the plist editor that comes with the (free) Developer Tools. Note that I don’t have any hex offsets for video card check bypass, as I no longer have a machine that triggers those checks and therefore have no way of testing any values I may find.
I’ve now found an offset for a G4 MDD dual 867 MHz machine, but do bear in mind that this system has 2GB of RAM and a supported graphics card, so I have not applied the graphics edits kindly provided in the comments. The only change I needed to make after applying the Software Update to 1.5.3 was:
0xb5e8: 40 9E 00 88 -> 48 00 00 80
