At this point I just wanted to see if it would even work.
I'm a very long-time PC user who's been playing with a Mac Mini for a few months as an evaluation toy; do I really want to switch to a Mac Pro?
So far I've found that although OS X has many advantages, hardware support could be improved.
OK, so that makes sense.
Basically, all you did was get OS X to recognize the camera. It didn't actually make it useful with iChat.
That's where you would need either a UVC-compliant camera or additional software to enable it to work with iChat (Apple's instant messenger / Video Chat program).
MacCam would be a much better solution if it did more than simply make it so that you could stare at yourself in the MacCam program (which is all it did for me when I played with it).
If you really actually want to use your webcam with OS X in a chat / video conferencing program, you should really just get one that's UVC compliant (such as the XBox web cam).
The risk of working with after-market patches, is that the usefulness of your webcam becomes reliant on updates by 3rd-party individuals who have their own lives and priorities. If Apple releases an update that breaks their patch, then you have to wait for them to release an updated patch.
If you buy something that's just compliant with the UVC standard, then you don't run the risk of having a $40 (or more) webcam being rendered useless.
Of course, it also makes financial sense unless you are working with a webcam left over from years gone by. For example, if you go out and buy a webcam and it's not compatible, then you've got the cost of that camera plus the cost of the shareware solution to fully enable it.
Or, you could just buy a UVC compliant webcam and be done with it. The XBox one cost me $39.99 locally, and can be had for as little as $32.00 on the Internet. Given that the shareware solution costs $10 to enable other cameras to work, a camera that costs $39.99 total (and works right out of the box) is a pretty good deal.
Especially when you consider that the other ones I've tried ranged between $20 and $50 and would then require the $10 shareware solution to make them work.
If someone is looking to buy a webcam, then they should be sure that it is UVC compliant. The XBox one I mentioned previously is, and it is very cheap. And, when compared against the other webcams I tried (using Windows to compare the video quality - since the other ones only worked right in Windows), I found that the XBox one had superior color representation and a clearer picture (the others had a lot of "snow" in the video).
Of course, everyone is free to choose their own route. I just hate to see people spend money on a camera and then have to buy a software solution that may not work long-term. Plus, an additional piece of software only introduces more opportunity for something to go wrong and complicates trouble-shooting.
I think the software patches are fine if you've got something you want to make work. But, if you are buying a new webcam, get something that's UVC compliant.
If you don't know if the camera is UVC compliant, only buy it from a store with an unconditional return policy.
