Howdy,

The < > pair highlighting is a setting in the `Parens Targets & Highlight Color' section of the Source tab in TeXShop->Preferences. But, as Bruno pointed out, there are possible problems. The problem doesn't exist with things like 
\left\{...\right\vert because the search is smart enough to not count the { if it is preceeded by the \.

Of course if you match < > you will also match << >> but each individual enclosed pair. 

It might be worth you while to create Macros that insert matched pairs setting the insertion point between the pairs so you are more or less guaranteed to match them up to begin with.

Good Luck,
