Q: Why wont the new version of aperture work with Nik complete software. I uninstalled and re installed Nik and it still wont work.

The incompatibility is not a bug, but a feature: some older plug-ins will never again work with Aperture; you need to get updated versions, compatible with 64-bit and sandboxing, see

Aperture 3.4 and later: Some third-party plug-ins are no longer compatible

Are you sure you have the latest updates? You may need to check Nik's site to make sure.

I believe that Nik is having trouble adhering to Apple's "identified developer" requirements.

there is a FAQ on Nik site regarding problems with their installers.

a guess.
