<div dir="ltr">Dear colleagues,<br><br>I am a long-time user of XCrysDen, however, after upgrading my OS, I installed XCrysDen version 1.6.2 on MacOS 10.15, and realized that anti-aliasing doesn't work properly. When I turn it on and off, there is no visual difference, except that the atoms slightly shift left and right. Playing with the anti-aliasing settings doesn't make any difference. Every other function that I've tried seems to be working as expected. I installed it using 3 different methods (precompiled, macports, fink), and they're all identical as far as I can tell. Any help would be greatly appreciated.<br><br><div>Thank you!<br><br>Mehmet Dogan<br>Postdoc, UC Berkeley</div></div>
