I've downloaded a file on my mac, tried to unrar it but it says "no files to unrar". I went back to the source, to check if I'd perhaps missed password protection or maybe miss a file. But the file size seemed correct and there was no password. So i wondered if it was perhaps the mac. Transferred the files to a usb stick, loaded bootcamp and hey presto the files extract just fine. Now, only have quite a small partition on my bootcamp setup, and most these files have been downloaded on mac-os, so its going to be a bit of faf to transfer them all to my usb, esp the larger ones. Can anyone recommend a decent program on mac? Is this problem common?
