Does Disk LED Pro work with El Capitan 11.4?
Yes, according to Compatibility information posted on the Mac App Store, the software requires OS X 10.6 or later, 64-bit processor to work properly. I've checked the official website and it redirects me to the same Mac App Store link. The changelog for updates displays only bugfix without any mention for El Capitan 11.4.
