Insecure startup item disabled PACESupport

then it's likely some other program installed that startup item and not pro tools. as I said, I saw another post where it was installed by Interlok. do you or did you ever use it? if not then just delete the startup item in question see if that stops the message. also look in the console log after you delete it. there may be some further error messages relating to this startup item or whatever program installed it.

this means that you had some program that installed this startup item which is incompatible with Snow leopard. I don't know which program that was. I think pace makes Interlok that installs this startup item. do you have it? if not, how exactly did you uninstall the programs you mention? did you us uninstallers 9correct way) or did you just trash the apps (incorrect way)?

this is not how you uninstall an application that was installed using an installer. I'm certain that pro Tools came with an uninstaller. you should have used that. if you can use it now. searching by hand will often not find everything. and did you specifically include system and hidden files in the search? if not your search didn't even look in any Library folders.

the support files that you mention should not affect anything. but there may be something else that might. if whatever application installed those things also installed some kernel extensions for example that could cause problems if they conflict with anything or are incompatible with snow leopard. however, such things would typically produce popup error messages too. you are most likely ok. but look at the console log as I said. see if there are some error messages related to PACE.

then you should be ok. you didn't use Migration Assistant to migrate applications from another computer, did you?

you are welcome! good computing.

I get the same error message when I start up my MBP running 10.6.2. The message reads that startup items in the folder "/Library/Startupitems/" folder have not been started because they do not have proper security clearance. But there is no folder labeled "Startupitems" in my Library folder. Any advice?

Go to the root of your drive (this can be done by clicking "Mac HD" or whatever the name of your drive is in the Finder sidebar) and look in the Library folder there.

Depending on the setup, OS X can have 3 or 4 library folders: one in your home folder (which affects only one user), one at the root folder (which affects all users), and one in the System folder (which is used only by the system). There can also be a network library.

If you clicked on the Library item in the Finder sidebar, then you're looking at your user's Library, which is why there isn't a StartupItems folder.
