being a macbook will make it harder to find others that did this. you should probably try here:
http://eab.abime.netI did it on my A1200, but thats not a macbook. Maybe you could get a PCMCIA-CF adaptor if you don't want to open the macbook. Else you would need to attach the CF adaptor to the IDE ribbon cable or use a second IDE interface if your macbook has it. I actually preferred to install my own workbench, because I prefer to have the software tools that I need and know how to use, and more importantly an OS without the hacks that can result in guru's. Yes it takes alittle longer but in the end you end up with a leaner, more functional Amiga thats entirely your own.
