Remembered to re-allot memory--I think I put it at 500,000--is that enough? The new iMac is a G5 and here's a copy/paste of its specs: Machine Model: iMac G5 CPU Type: PowerPC G5 (3.0) Number Of CPUs: 1 CPU Speed: 1.8 GHz L2 Cache (per CPU): 512 KB Memory: 1 GB Bus Speed: 600 MHz Boot ROM Version: 5.2.2f2 I can't do any kind of math, including the computer-related variety--what is half a gig in numbers??
