Like many others today, I got the long-awaited email (I emailed them 3 times in the past year, the last time over 5 weeks ago) regarding OS X support for their scanners. I have a fairly new Astra 4000U and bought it due to its size and USB interface.
"Umax currently has made no commitment to supporting older professional models under OS X at this time. Also, no consumer-level (Astra models, or older consumer-level) scanners will be targeted for support under OS X."
Well, UMAX, go screw yourselves... wait, it looks like you already are... I'd like to say it's been fun, but, I don't think it has been. In fact, it sucks. Do not go out and buy a UMAX scanner. Their support sucks worse than their software. Buy Epson or Canon or something else. No Umax!
