Got really tired for seeing the SPOD (Spinning Pizza of Death) in the Finder while trying to navigate in the folder hierarchy. Happens off and on every 30 seconds or so. Finally tracked it down to something dumb that Dropbox’s contextual menu code is doing (version 2.10.41).
It’s a bit of a pain to remove but here’s what you need to know:
is where the nasty is. Contents:
The “###” is the user id number of the current OS X user (probably 501, 502, etc).
You need to move the “DropboxHelperInstaller” out of this folder or it’ll just keep re-installing the other stuff. I didn’t track down which of the two bundles are causing the problem, but it’s one of the “FinderLoadBundle”, or “DropboxBundle.bundle”. I removed both of these and the “mach_inject_bundle_stub.bundle” and that seems to solve the problem (after you quit Dropbox and relaunch the Finder).
Unfortunately Dropbox really wants to repair itself so it will keep prompting you every time it launches to put these back:
Just select “Cancel” and it won’t be able to put these buggy files back. Everything except the Finder integration seems to work fine and the Finder doesn’t keep dying inside dropbox contextual menu code for some indeterminate (but too long) amount of time. I’ve told them on Twitter but they haven’t fixed this yet
UPDATE: As of Dropbox v2.10.52, and only when running on OS X 10.10.1, there’s a checkbox for “Enable Finder Integration” that might turn this stuff off more easily. I haven’t tried it yet, but I’m hopeful.
