Well this is a mystery!  It may of course be coming from you forging ahead in Mac OS versions while NRAO lags behind.  I have looked at the 2 lines 325 and 351 in TVDEVS.SH.  Both of them are searching for files in /tmp that may or may not be present.  They both say 2>/dev/null so you should not see the error messages that you do see.  Has Mac changed a fundamental grammar??!  The expr message is probably the most serious but I have no idea where this comes from.  The string should probably be '1' rather than ' 1'.  TVDEVS has an option that might help.
export DEBUG="YES"
or setenv DEBUG 'YES"
before starting aips.  Note that the 2 reported messages imply that you are stating tv=local.  That really is preferable but with all that you have set up you might try the internet TV connection rather than the socket connection (leave tv=local off) or try tv=local:1 specifying that you want tv #1.
TVDEVS.SH is in $AIPS_ROOT.  You could add more comments (perhaps triggered by DEBUG - there are many examples) to try to see what is going wrong.  The logic is fairly simple: /tmp needs socket files with names that include XAS. the local tv number, and the host name.  It looks to see if there is one matching your request and if not makes one.  Try ls /tmp and see if there are files name LOK, XAS, MSS, and/or TKS.  If so delete them and try again.
I don't know what else to suggest from home where I do not have access to an Mac yet say one at the OS level you are trying.  I have not heard from other Mac users so perhaps there is something local to your machine rather than systemic.  Or perhaps no one has gone to 15 and then tried aips....
Let me know what you find.
