Have they fixed the lack of font smoothing in PDFKit? This would definitely affect TeXShop and Skim. I’ve been hesitating to upgrade to High Sierra because of this (and other reasons). I did find this comment from someone dated Feb 9 in the Apple Forums:

Herb, have you tried 10.13.4 yet?

But since the page changed notification was not sent, it scrolls to page 6. I did not work around this bug, but it was also automatically fixed when Apple fixed their bug.
