Microsoft msn messenger for Mac does not presently support webcams.
This applies to ANY webcam you might buy for your mac.
However, some note success using amsn or msn mercury, which are free msn 'clones' which let you use your mac to talk to pc users on the msn network.
Hope this helps,
Hey Guys! I am a Windows user that just ordered a mac online a few days ago and it occured to me that the included firewire webcam will not work with msn messenger for the mac. I am not a user that complains about using MSN on the mac because I am both PC and mac user so I can stick with msn. I would still like to keep having video conversations with my msn buddies (although I already have a ton of iChat buddies) and I would like to know if there is actually any USB webcam's for the mac. I've hunted and hunted and havn't found anything. A laptop webcam would be prefered but if I have to I will use a desktop webcam. Thanks C|Net!
