Hello all, I'm having a problem with my iSight camera (specifically within iChat) in my MBP (running 10.5.2, fully updated) and I know that it worked at least up to a certain point, because I took a screenshot of my iChat buddy list at 9:08pm on the 21st. I've been backing up with Time Machine since then, so my question is: Is there any way for me to use Time Machine to check for any and all folder/system/preferences, etc. changes since that point (21 April, 9:08pm), hopefully analyze the error, and then either restore the correct file(s) or just take my system back to how it was at 9:08pm on the 21st? Some info about the iSight problem: PhotoBooth works, but the green light only goes on when I'm actually using the program - the camera turns off when the program is on and in the background (i.e. when I'm using Safari). At that point, the image freezes. Skype sort of works, but I've had to frequently deselect and then reselect the "use video" checkbox in the Preferences, and sometimes the iSight camera wouldn't show up in the pop-up menu where one would select the video camera to use (the internal iSight is my only camera). In iChat, my Buddy List only shows the phone/conference call icon next to both my name and my buddies' names. When I go into preferences and click "Audio/Video", the green light next to the iSight DOES come on, but it DOES NOT show a picture in the iChat preferences box where it would normally show the video picture; rather, it says "This computer does not support video conferencing." Although it says that, when I click Audio>Connection Doctor in the iChat menu bar, and then select Capabilities, it tells me that I am unable to do 1-on-1 Video Chat, Join Multiperson Video, Host Multiperson Video, and Share My Screen because of (Slow Network), but it also says that I am unable to do Video Effects and Backdrop Effects because of (No Camera). I don't get it. In the System Profiler, the iSight is properly (as far as I can tell... it knows it's an iSight camera, just like it always has) recognized by the computer in the USB bus. I'm pretty sure my network speed is not particularly slower than usual (but what do I know?) because I downloaded the 99¢ Movie of the Week (Ronin, so far so good; I'm finishing it tonight) and it downloaded fully within a few minutes, to the approximate tune of about 4-4.5Mbps, I think. I have reset the SMC (but there was nothing different when I rebooted... maybe I did it incorrectly? Should I have recognized that something had been reset?). Anything else you need to know? Let me know and I shall provide (screenshots, more info, etc. Thanks very much!
