This update won't install on my MacBook 2.4 GHz Intel Core 2 Duo w/4 GB RAM -- running OS 10.6.3. After several attempts, now (using the "dmg" file) it says: "Cannot Install Please click the Quit button • Adobe Fireworks CS4 - Already Installed" but it isn't as far as I can tell.
I have CS3 on my computer as well. I have had a love/hate relationship with Firewire and Dreamweaver going back for many years. I was hoping they would get better when Adobe bought them out, but I guess not.
They are both practically unusable on my old PowerPC, but acceptable on my Intel MacBook. Not great -- just acceptable.
