On the mac I get the following:

Summary:

  PASS     12671
  FAIL        13
  XFAIL        3
  SKIPPED      7

out of the 13 fails, 7 are in conv, and 1 is bug 38236.
The remaining 5 are as follows:

1 failure in chol-cc.tst which is a tolerance issue
1 failure in testing error messages in figure.m
2 failures in datestr, due to uppercase/lowercase differences.
1 failure in svds which is a tolerance issue

None of these looks very bad, I think the main issue on OSX is that syntax 
highlighting crashes the GUI.
Below is the text of the make check failures on OSX.
