This error means that the folder named ~/Library/Services/NoteBookHelper.service (or its contents) is not writable by you. Try changing read/write permissions for it by selecting the folder and choosing Get Info from the Finder’s File menu.

The ”~” character, in case you don’t know, is UNIX shorthand for your home folder. Your home folder has the same name as your login account name and is located in /Users.


If that doesn’t work, try deleting NoteBookHelper.service (and restarting NoteBook: NoteBook will reinstall it).

I found the NotebookHelper.service file in the Trash. I deleted it. Notebook did not reinstall on restart.

Any suggestions?

It may be that the folder named ~/Library/Services/NoteBookHelper.service (or its contents) is not writable by you. Try changing read/write permissions on it in the Get Info window in the Finder.

I am not finding a folder for Services in ~/Library and a search for file named NoteBookHelper.service resulted in 0 files found.

That could be the problem. Try creating a “Services” folder in your Library folder. Then run NoteBook and see if that helps.

I’ve got an older G4 PowerBook too, and had the same problem. As suggested, I created a Services folder and moved it into the Library folder.

Then I created a NoteBookHelper.service folder. When I did that, OS X gave it an icon as though it was an application, but it’s not, really. I moved that into the Services folder, rebooted NoteBook, and the error pop-up went away.

Wherever it went, I hope it stays there.
