How to handle System Font change between OS X 10.9 and 10.10

Some but not others of the beta testers of my current app project have reported clipping of NSTextField views. This had me stumped until I realized that OS X 10.9 and 10.10 use a different font as System Font (Lucida Grande vs. Helvetica Neue). Is there an accepted practice for programmatically handling this situation? I realize that I can make my NSTextFields wider; however, I am looking for a solution where several NSTextFields that are adjacent to each other will not clip. Many thanks.

What is the default system font for Mac?

System fonts The primary system font in OS X El Capitan and above is San Francisco. OS X Yosemite used Helvetica Neue, and preceding versions largely employed Lucida Grande.

If you use Cocoa's Auto Layout facilities, this is a non-issue. All of your nibs will automatically readjust to the new font metrics. https://developer.apple.com/library/mac/releasenotes/UserExperience/RNAutomaticLayout/
