I just installed the current stable release on a recently acquired MacBook (early 2015), and my heart sank. The fuzziness described in the original post was dismaying -- perhaps not "unusable", but an impediment to use, certainly.
After playing (unsuccessfully) with various combinations in the settings, I did a bit of websearching, found this thread, and so glad I did!
I've now installed the current beta-2, and it is crisp and clear! I haven't used LyX in anger yet, but am now encouraged to persevere.
Kudos to the devs! This is a significant step forward in usability on this platform.
