I've received the same message when opening Bento, only since updating to Yosemite. Once I type my password, Bento opens & functions perfectly, however. I've synced it with Bento 4 on my iPhone and iPad and everything works exactly as it always has. The nuisance is that I used to keep Bento open on my Mac all the time so that I could sync from my devices as needed. I no longer do this, however, because the atos message will hang my computer on reboot while it's waiting for the password. There is apparently a way to tell our systems to allow this access all the time, thus negating the need to type the system password. I haven't found clear directions for doing this yet, however. If I figure it out, I'll post it here. From my experience, though, if you type in your system password when asked by the atos message, Bento should open and function perfectly. If the issue is with data backup on your Blackberry, maybe the atos message is related to all database backups, which is what your Blackberry backup is. There must be a debugging process that is run when first accessing a database. Considering you don't use Bento, this sounds like a Yosemite bug related to database code more than a problem specific to Yosemite. Whatever the case, I sure hope someone figures out how to permanently authorize access to the databases so that this hangup can be alleviated. I'm not at all proficient in writing or amending code, but I'll keep researching a solution. Based on what I've read so far, I think it's a pretty simple one.
