I have an iMac 27, trying to profile monitor again, but Mountain Lion voided out the EyeOne Match 3.73 software. I think I have Revision A or B of the EyeOne Gretag puck; it's medium grey color. Is there any other software that will calibrate/profile an Imac 27, running Mountain lion, using that puck? Thank you in advance. Tried using Apple built in software but wow what a difference in profile. I've always used 120 lumens and 6500 Kelvin. I downloaded a "Lion" version of the XRite software, but it does not recognize my puck, via USB.
