Well I know nothing about macs or safari, but there is a possibility Murphy's Law is at work. February 10 was the scheduled
release date for Mepis 6.0-4. Could be something (how's that for vague?) going on with the mirrors with this addition.
otoh it could be coincidence.
edit/ try to start an ftp transfer of ubuntu
if that transfer also fails, wait on someone with mac advice. There's a few mac users here.
Or are you having difficulty even reaching this page?
