Re: [OS X] Can't move apps from "Applications" to a su I moved it first and waiting for hell to break loose... After a few weeks, nothing blew up :-D Then I really did trash it.
I use Thunderbird but Calendar insisted on opening Mail (silently) to deal with invitations, i.e. sending them to others mainly. I tried every solution I could find to get it to stop and short of removing it, nothing worked. After removing it, everything Calendar related still worked fine. I don't know if it used Thunderbird to send invites now that it had no choice or if it sent them via commandline.
What is a full update vs a delta update ? Well, I know what they probably mean. Delta would basically be a "patch". Didn't know users had the option...
