Well, no. The Gerber file is designed to draw the pattern on film with light, with the apertures setting the shape of the light beam. It can flash round, square, oval and thermal relief pattern in one blink, with one like of G code. You can't do that with a mill. If you want to actually cut a working PC board with a router bit, you need to "convert" the file quite radically with a trace isolation program. It figures out which traces and pads are connected, then draws a series of moves around the entire extent of the net. Eagle is one of the programs that can do this, but the somewhat odd format of this file may be an obstacle. Could the person who made the file on the Mac specify for trailing zero suppression on these files and re-generate it? I believe I could then read it on my Protel software, for instance, or make it plot on my photoplotter. The industry standard is for Gerber photoplot files to have Leading zeros suppressed, and for Excellon drill files to have Trailing zeros suppressed! All part of the history of the electronics industry, dating back to punched paper tape.
