I am getting ready to install BOINC 7.0.27 on my computer and the installer throws a flag that I will need to restart my computer after BOINC is installed. I never remember seeing that flag on any previous installation of BOINC in the 5-6.x versions. Is this new with BOIC 7.0.x?
My System
Mac Mini 2010 version
OSX 10.6.8
8GB of Ram
I aborted the install with that warning and am waiting on a post saying if the restart needed is normal. I am wondering what BOINC is fiddling with so deep in the OS that it needs to restart the OS to successfully install? I don't believe any application as a general rule needs to restart the OS. Macs are famous for their drag and drop installs. Apple has made a big push for that to be the case.

Are you the same person as user 'B-Man', who just asked a very similar question over at SETI? Even if not, you might be interested in the reply I wrote there.

Or you might like to read BOINC's Sandbox design document.

Probably something to do with the Eight changesets marked 'Mac installer: changes for OS 10.8 compatibility':

Answer from the developer:

Because the installer is removing the old boinc_master and boinc_project users and groups and creating new ones with different IDs, to solve some issues. The reboot is needed to guarantee that the OS recognizes the new values. This is a one-time thing; the installer won't require a reboot for further upgrades or reinstalls.

This change was recommended by Apple:

- Mac installer: follow recommendations of Apple Developer Technical Support: create users and groups boinc_master and boinc_project at first available UserIDs and GroupIDs starting at 501 instead of 25 to avoid conflicts with UserIDs and groupIDs which may be added in the future; use Directory Services to find the user names of all human users instead of stepping through the entries in the /Users directory.

Yes I am. I said thank you in that thread and I need to say so here also. Thank you for the time taken to answer my question. I also know I came real close to the line of being rude in the SETI thread so I apologize for that also.
