Dear Michael and Dalyoung, In order to test again and reproduce the problem you encounter I removed my texmf-cache and typeset the example: here is what I observe.
--- with \enablemode[lmmath] the \hbar appears and is a math italic « h » with a bar in the top third of the vertical part of the letter --- without \enablemode[lmmath] the \hbar appears and is a roman « h » with a bar in the top third of the vertical part of the letter Your error message seems to indicate some character in texgyretermesmath-regular is not found and points to the file mkiv-base.map is this file present on your context tree? On my installation the file exists but there is no mention of texgyretermesmath-regular… So I am clueless about the issue because all three of us we have updated to LuaTeX, Version beta-0.74.0-2012122517 (rev 4541), ConTeXt ver: 2013.01.02 18:19 MKIV on Mac OS X Mountain Lion.
