OK, so I came back from work today and logged on to the Pentax Live Chat. This is what they told me
Randall S.: Thank you for contacting Pentax Chat Support. How may I help you?
David F: Hi Randall... I was hoping to get some support with a problem I'm having with my Pentax *istD and the Remote Assistant software
Randall S.: okay Randall S.: which version of remote assistant are you using.
David F: Remote Assistat software (version 1.01 - for Mac OS X)
Randall S.: okay, what is the problem you're having?
David F: at first I had trouble finding the installer since the Pentax website has a link to it that only contains the installer for OS 9, although the instructions indicate that the file has the installer for other OS versions... but ayway... I got the installer from another pentax site (I think either the canada site or the japan site)...
Randall S.: what version of the Mac OS are you using?
David F: I installed the software (Remote Assistant version 1.01) but my camera is not recognized by it. I can see the camera as an external storage device, but Remote Assistant doesn't shows all its controls inactive (grayed out). I have Mac OS 10.4.11
Randall S.: okay, one thing you can try is right-clicking on the remote assist icon and select "run as admin"
Randall S.: if that doesn't work I will have to check on the compatibility of the software with your OS.
David F: yeah, I don't see an option to "run as admin"
Randall S.: okay, hold on.
Randall S.: i have confirmed that remote assistant for the ist D is not compatible on your operating system. unfortunately, there is no upgrade for it.
David F: OK, so what versions of Mac OS is Remote Assistant compatible with?
Randall S.: according to our records only OS 9.0 through 10.2.8
David F: is there any way to utilize another version of Remote Assistant (intended for other cameras) with limited functionality on Mac OS 10.4 with my istD?
Randall S.: no, they are not compatible with the ist D.
Randall S.: the only other versions are compatible with the K10D and K20D only
David F: Do you know if Pentax is working on an update for the istD remote asistant or a future version of Remote Asistant that will work with all pentax cameras?
Randall S.: Pentax is not going to updating that older version of remote assistant.
Randall S.: the only version we will be offering will be compatible with the current line slrs.
David F: OK, I guess that means I'm out of luck in using my istD on my Mac?
Randall S.: i'm afraid so, as far as remote assistant goes.
David F: Ok, well, thank you Randall, this at least clarifies my questions.
Randall S.: Thank you for dropping by, David, and have a great day!
So, I guess my project to take tethered pictures with my mac triggered by motion the motion sensors on another program (using a webcam as a sensor) have been truncated... Unless anyone out there knows of a way for me to use my *istD with my Mac running OS 10.4 (maybe a third party driver)? Preferably one that doesn't require a huge payment. I think there's a program called Capture One Pro. But it costs more that what I paid for my camera!
