You are the first person to mention the TeXShop magnifying glass problem. This
has bothered me since the first El Capitan betas and I reported the bug to Apple
early on, and later provided them with the source for a short 16 line program
duplicating the problem on El Capitan and working perfectly on Yosemite.
I got no replies to the bug reports.
Leaving out details, magnification works by creating an NSImage with a PDFImageRep.
Then I call
[NSImageDrawInRect: destinationRect fromRect: sourceRect operation: theoperation fraction: thefraction]
On Yosemite, the PDF in sourceRect is redrawn in destinationRect at a higher resolution. In
ElCapitan, everything is converted to a bitmap and the bitmap is just magnified. Hence the
PS: Otherwise I like El Capitan and have run into none of the other problems.

Much more serious is the disappearance of all (tens of thousands) messages from my main account. In addition, no connection to my incoming POP server or my outgoing SMTP server seems possible via Mail.

The preview window now renders text too heavily, and, when using the magnifier in the preview window (the one that magnifies a part of the window, not the entire window) the result is now essentially unreadable, with very low-resolution bitmaps being displayed instead of a re-rendering of part of the pdf at higher resolution. (On both machines, System Preferences/General/Use LCD font smoothing ... is not checked.)
