The three computers in your "All Computers" list look like they could actually be the same machine. Certainly there was at least an OS upgrade and perhaps a BOINC upgrade but the hardware may be essentially the same. It might be possible to merge them all into a single Host ID.
If you click on the computer ID of the most recent of your machines, you will get a computer summary for that ID. At the bottom of the summary page you will find a merge function that you can use to attempt to merge this ID with any others that BOINC thinks might actually be the same host. You may not be offered the opportunity to merge the one with the older OS but you should be for the two others.
Of course, if they really are separate machines, you shouldn't try to merge them :-).
If they are duplicate IDs, you can usually avoid this duplication from happening by keeping the configuration files in your BOINC folder rather than deleting them if you are going to have a break from crunching but intend to return at some point in the future. You can always uninstall BOINC but keep what is left of the BOINC folder and install "over the top" when you want to start again. I'm quoting Windows behaviour but I guess it should be something similar for a Mac.
what happened to my credits?
