Mac Remote Software?

I dont know of any software that can run directly on the Mac. Depending on how old your mac is, you can run virtualization software on it and have your cake, and eat it too. I use parallels and windows 7 pro. You can run both side by side. You can also install a bootcamp partition, and you can boot directly into Windows. IMHO it runs Windows 7 better then my actual PC. The only problem is the price you're willing to pay. Parallels will run you about $80, depending on where you get it. If you have a copy of Windows XP or 7 around without a used license, then you dont have to buy Windows OS, otherwise you're stuck with that price as well. May not be the answer you're looking for, but most likely the only decent option.

I have a second (older) Intel Macbook Pro that I have running bootcamp and windows XP (plan to upgrade to Win7 soon) I use it for my astronomy/astrophotography stuff, as it is a faster computer running XP than my old buggy Toshiba laptop was. I could always use that I suppose. It's been a Windows workhorse so far running 100's of hours outside in damp humid nights with not a single glitch yet (knock on wood). I plan on switch over to Windows 7 as XP is getting a bit long in the tooth, the only trouble I have with it is my USB to serial (DB9) ports keep switching com port numbers on me each time I plug in my serail devices. I need to keep at least 1 port open in 1-8 but it always jumps to ports 11-21 open and one of my focusers only works in com ports 1-8. I know why it's doing it, but I can't figure out how to stop it, my friend running the same equipment said his stopped doing that as soon as he upgraded, so that is planned after an astronomy trip for work to NY in late April. Don't want to change over until after my meetings where I'll need my mac/pc running! Thanks for the suggestions. I also own both Parallels and VM Fussion - would just need to upgrade them to t latest if I go that route, I prefer bootcamp as it was always a lot more stable and faster.

Is there a good remote camera control for Windows or should I just stick with the Canon software? Remember I want to try to get this going really cheap of free.

Just tried DSLR Remote to no avail either, it crashes immediately upon camera connect attempt. Tried 1.5 and 1.4 versions. Looks like Canon won't play nice with Apple any more. Worked under OS X 10.2 if I recall, no more it seems, and I have a lot of cameras to try, Canon 20Da, 30D, 7D, 5D, 5DmkII, 5dmkIII, 1D and 1Ds, none connect to any program via a tether. The computer sees the cameras no problem in the OS under system profiles, just can't control the camera at all and no program will see the cameras on connect attempts. Bummer, looks like Windows is my only option now.
