I've been using MacTex-2012 for a while (well, since 2012) with no problems (well, relatively few problems). Today, while using tlmgr (which I hadn't played around with much before), I got an error message similar to that described here, suggesting that it wouldn't play nicely unless I updated to a newer TeX Live distribution; I followed a couple of links to re-install TeX Live 2014 as described here.
Now, it seems that TeX Live 2014 is installed properly, as it shows up under usr/local/texlive/2014. However, I don't think TeXShop is recognizing the installation. In System Preferences, the TeX distribution pane allows one to choose the system-wide TeX distribution to be used, which (I believe) specifies the distribution to be used by TeXShop. This pane only shows TeX Live 2012.
I know that I can re-install MacTeX to solve the problem (and it seems that that would have been the right move in the first place). However, I'm wondering if there's a way to make my system recognize TeX Live 2014 without having to download another big file.
