Thank goodness the printer came free with a camera I bought. I have an iMac i7 10.6.7. I have been having lots of problems with this printer's quality, inability to change preferences for paper quality or change color preferences..shoot I can't get it to do the same thing twice, settings I can use never "stick" and it reverts to default. One time I got the results I wanted, the next sheet came out with the darn default again. I found a driver on Canon site, but when the compatibility check was run it said I could not install it on this machine. I have had a project I am doing for someone and for the last 2 weeks I have thought daily of getting out the baseball bat! HELP! Thank you.
