To open NotificationExec you must install Rosetta

Thanks ... Ken

Right, Rosetta is a technology that allows an Intel Mac to run applications that are compiled for PowerPC. Your NotificationExec is one of them. I say just go ahead and install it and don't worry about it.

Use the installer extras that are included in the install CD to install Rosetta...it won't harm anything and can only fix the issue...you're lucky you only get one per min...after install of Snow Leopard on my Mac Pro I got one every 10 seconds compounding the replication exponentially filling my dock and my screen to the point I was afraid it would choke the computer. The only way I could get rid of them was to install Rosetta. I wound up clicking literally hundreds of them closed during the first 20-30 mins that it took me to do the additional install of Rosetta and the other software...once installed the problem resolved itself and I have a happy Mac again.

How can you tell if Rosetta is installed after Snow Leopard upgrade (I saw the Rosetta install dialog, but it disappeared on it's own before I clicked Install)?
Thanks

NotificationExec is software that is installed when you install some of the Maxtor external harddrive software. I believe it is part of the 'OneTouch' system they have. If you do not use the Maxtor Manager or whatever Maxtor software came with your hard drive, you can uninstall it. Contact Maxtor support for the uninstall software.

Beware though that their uninstall software will not remove everything (at least in my case it didn't). It left a file called com.seagate.notificationexec.plist in the 'Library/LaunchAgents' folder. Any plists in this folder are executed by launchd when your computer is started up. In my case, this plist was trying to run some of the notificationexec software that maxtor installs. Since it was no longer installed however, I kept getting the console message:

9/18/09 11:35:57 AM com.apple.launchd.peruser.501[89] (com.seagate.notificationexec.plist[190]) posix_spawn("/Library/Driver Support/NotificationExec.app/Contents/MacOS/NotificationExec", ...): No such file or directory
9/18/09 11:35:57 AM com.apple.launchd.peruser.501[89] (com.seagate.notificationexec.plist[190]) Exited with exit code: 1
9/18/09 11:35:57 AM com.apple.launchd.peruser.501[89] (com.seagate.notificationexec.plist) Throttling respawn: Will start in 10 seconds

This would pop up every 10 seconds. By removing the plist com.seagate.notificationexec.plist from the 'Library/LaunchAgents' folder, I stopped the console messages.

after closing out the popup windows, you have a few seconds before the next popup to trash (using your admin password)
/Library/Driver Support/NotificationExec.app

and for good measure, trash
/Library/LaunchAgents/com.seagate.notificationexec.plist

might want to search/investigate/destroy for other files w/ similar strings, but the app is the key

the plist might be useful if you have other seagate/maxtor programs, so decide for yourself if it's clutter

Had the same problem.
