OK - this and the fact it works on the host machine is good to know.

Linux 'top' does list memory usage, both per process and for
the system in the text at the top. There are other tools for
monitoring IO like iotop - but you could also probably just
watch the host Apple OS X System Monitor for this.

This does sound like the VM hasn't got enough RAM to run
BLASTP against NR efficiently.

In the Galaxy folder? Maybe the default log filename has
changed since I setup my machine... are you running Galaxy
as a daemon, or running run.sh at the terminal directly? If the
later, try something like this:

$ sh run.sh | grep -i blast

(If you don't get much output, adjust the logging level in the
universe_wgsi.ini configuration file.)

That's progress - the hardware itself is capable :)

There are clearly two separate issues, (1) getting BLAST to run nicely
on your VM - which I think is running out of RAM, and (2) sorting out
your Galaxy BLAST database configuration.

Something to check is the read permissions on the BLAST database
files (which Linux user are you running Galaxy as, and can that user
read the database files and their folder?).

I'm keen to see the Galaxy log output to see what exactly was the
command line being used to run BLAST, which would help with
debugging where the problem is.

I used to do my Galaxy tool development on Mac OS X, but it didn't
work 100% right, and in any case many of the tools I wanted to
wrap and run within Galaxy were Linux only - so now I just ssh
into a Linux server to do Galaxy work. Given the main Galaxy
development and the Penn state Galaxy server all happens on
Linux, you'll have a much easier time under Linux than Mac OS X.
