openbsd on present day macintosh

[Mayuresh Kathe]

hello, does anyone have any experience with
installing and running openbsd on a present
day macintosh, say a macmini?
would like to know words of caution and
advice before i commit to purchasing a
macmini and using it exclusively for openbsd
software development (my current thinkpad is
dying quite rapidly).
thanks.
