I have installed CS4 illustrator for mac and from day one, everything I draw looks pixelated. I have uninstall and reinstalled about 3 times and called Adobe to trouble shoot and nothing seems to change. I have also changed my preferences to try to fix the problem with not results.
You may have View>Pixel Preview on, if ticked, you may tick to untick (or tick Overprint Preview).
In Preferences>General, is Antialias Artwork on or off?
thank you both for the reply...it ended up being the anti-aliased box not being ticked. Works like a charm.
