It's hard to tell without knowledge on both Macs and how you installed CS4 on both of them. Are both Macs intel? Did you do a clean install from a disc? Download? Did you try trashing the prefs on open? http://forums.adobe.com/thread/526990
For what it's worth, I can run CS4 on Mountain Lion (10.8.2) so it's more likely to do with the individual system setup rather than the application.
And take a look at Adobe Forums: InDesign CS5.5 Not Responding where you'l find directions for creating a hang report and then forcing a crash and generating that report. We can often pinpoint the problem if we have that information.
Thanks! From what I understand we did not do a disk install, rather to copy via Firewire from the old computer to the new one, then deactivating it from the old computer.
I will check this out, much thanks for the link
Thanks for this link as well Peter, this works for CS4 as well?
As far as I know.
And if you really tried to transfer fom one machine to another, that's most likely your problem. Uninstall, run the clean tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3) and reinstall from the disks. Even if it turns out not to be the cause of this particualr hang, it will bite you at some point.
Ouch, I see.. reason why we did that was because we lost the installation disk, according to my colleague -_-"
But good point, lemme try to dig it out of wherever it is now!
Igf the software was registered and you can't find your original disk or serial number you can get the serial number from your account information at Adobe.com and you can downlaod the trial installers at Download Adobe CS4 and CS3 Free Trials Here (incl. After Effects) | ProDesignTools and enter the recoverd serial number to convert to a real install and reactivate.
Note that it is very important that you read that page and follow the directions exactly to get the installers to download. Failure to follow the directions will not work.
