No luck. That is the out of box preference. I get the same result with either server option. Also, opening the package browser complains it cannot contact any SqueakMap server.

Additional info: I can run the 3.7a-5566 image and connect to both the update servers and squeakMap servers, but the update process stops before update 5786 and says it can't load the last ~82 updates.

Looking through the archives, I found Doug Way's email that pointed to a more recent VM for the Mac as the solution to the problem: http://lists.squeakfoundation.org/pipermail/squeak-dev/2004-March/ 076388.html
So I downloaded the "3.7.2Beta1 OS X VM" from John McIntosh's file sharing page: http://homepage.mac.com/WebObjects/FileSharing.woa/wa/ default?user=johnmci&templatefn=FileSharing.html&xmlfn=TKDocument.1.xml& sitefn=RootSite.xml&aff=consumer&cty=US&lang=en and all seems to work fine again.
Since it seems likely that all Mac OS X users will hit the same problem with the VM provided in the current download, I'd suggest that the current download package be upgraded right away. Of course, I don't know what other problems may lurk in the 3.7.xBeta VM.
Thanks to John M. and Doug W. for solving my problem.

Ok, so a bit of explanation why this is a problem in 3.5.x and 3.6.x, fixed in 3.7.x
The issue is that in 3.5.1b2 we migrated to the Unix network code. Now part of this problem arises because the VM must call a routine aioPoll() to check for pending socket interrupts. Previous Carbon Mac VM 3.5.0x and earlier used Open Transport which got callbacks at interrupt time giving good responsiveness to socket accept processing.
The call to aioPoll in the carbon VM is done on idle processing as one example, which is where the issue was.
In merging the code I wrote it to make that call, then nano-sleep the interpreter pthread using pthread sleep logic to reduce CPU usage. Problem is that this and how the timer checks would interact would perhaps stall the VM from servicing any pending socket interrupts, if things were idle. The issue of course is everything goes to sleep for 16 ms or so as the updates in the background are stalled, and morphic in the foreground is idle awaiting data incoming on the socket.
This was first reported to me as poor socket accept turnaround.
In 3.7.x I changed the routine to use the aioPoll() logic which nano-sleeps using select for micro/nano seconds, and then gets woken up when a socket interrupt occurs, so as you see the servicing happens much faster. This consumes a bit more CPU time, but fixes the issue.
