Pentax has announced a Mac OS X version of its Remove Assistant 3 software. This tool enables you to remotely control one or more tethered K10D digital SLRs from a PC or (now) Mac. You can control almost all camera functions as well as triggering shutter release manually, at regular intervals or at specific times. With more than one camera attached you can even achieve 'same time' synchronized exposures. In addition to releasing an OS X version of RA 3 Pentax has also posted an updated version for Windows which includes a small bug fix. Download links after the jump.
