I agree, I don't think Carbonite is ready for Macs. On my Macbook Pro it has been sitting at 6Gb to upload for 3 weeks and hasn't moved yet. I have uninstalled and reinstalled numerous times but nothing helps. If you contact support you get the email telling you to uninstall and reinstall. I have it on 4 Macs and I don't think I am going to renew.
