Thanks for the good work!
As I noted a number of posts ago, I figured out how to start Skim without the system preference “Use LCD font smoothing when available” and without affecting other applications. I found that when I did that, fonts went from wretched to acceptable looking, though slightly fuzzy. I subsequently discovered that the fuzziness disappears when (and only when) magnification is set to exactly 100%. In that case, and when your latest fix to TeXShop is applied, Skim and TeXShop look pretty much identical. In Skim’s case, changing and restoring the magnification doesn’t do anything; only setting it to 100% does.
In Skim’s case, I’m beginning to suspect that the “Use LCD font smoothing when available” preference may cause font smoothing to happen twice in cascade, or maybe even two different font smoothing processes to happen on the same text.

So I modified the preview engine of TeXShop so that the magnification is changed and restored internally every time a document is opened or compiled.
