Richard Séguin,

I still don't know the rationale for why the blur occurs on non-Retina displays, but I found that the blur vanishes when the magnification scale of PDF is changed. 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.

This is nothing but an ad hoc solution, but it seems to work fine at present.
