Assuming you're running OS X on your Mac and have a network card in your Amiga, enable Windows Sharing in System Preferences then use SMBFS to mount your Mac's shared folder on the Amiga. Otherwise, use a USB memory stick formatted as FAT and use FAT95 on the Amiga. Formatting the memory stick on the Mac will work (go in to Disk Utility and change the format to FAT before erasing).
