I have not been able to produce the minimal example, but I get this error

* Note that since I won't overwrite the other colon-like commands, using them
* will lead to inconsistencies.

There seems to some problem with braces but I cannot see any alone brace.
I think the problem is probably with unicode-math, but I do not understand why.
What may cause this problem?
Best Answer
It does not compile because of the line 11, uncomment
%\usepackage{unicode-math}and uncommentwhere I don't know anything about the package. Perhaps someone here able to help with it you?
Code Compiling with OSX Texpad 1.4.7 -- this should be the newest so the same as yours
