Though I find San Francisco system font decent, I have always enjoyed using Lucida Grande more than any other system fonts on Mac. And I'm really glad to know that there is a tool developed by GitHub that allows you to change the macOS High Sierra System Font to Lucida Grande on your Mac.
Named as macOSLucidaGrande, the tool works reliably and easily lets you switch between San Francisco and Lucida Grande font, which existed before OS X Yosemite. As for functionality, it has a slightly larger spacing and is a bit thicker as compared to San Francisco font. Hence, your eyes may prefer the former. Wish to try out this tool? Make sure to back up your Mac just to remain on the safer side of the stream in case of any mishap before getting started!
Step #1. First and foremost, you need to go to Luming Yin's Github page to download macOSLucidaGrande.

Want to go back to the San Fransisco? No problem. The software makes it easier to switch between the fonts.
Step #1. First off, launch the macOSLucidaGrande app and then click the “San Fransisco” tab.
Step #2. Now, you need to click the green check button to reset the San Francisco font as the system font.
Step #3. Next, you have to reboot the Mac.
That's pretty much it folks!
Personally, I have enjoyed using Lucida Grande as it's a bit easier to the eyes and make a reading text more convenient. Let us know your feedback about it in the comments below.
