A number of people have asked if LockRattler could run on El Capitan: I’m afraid that despite my best efforts to get Xcode 9 to make that work, it doesn’t look as if it has. I still welcome anyone still running El Capitan to try it, though, please.
Version 3.5 of LockRattler has now been ported to Swift 3.2 and built to run properly on Sierra, High Sierra and, allegedly, El Capitan. Although I have tested it on Sierra and it all looks to be working properly, I am unable to test it on either El Capitan or High Sierra. I would therefore be very grateful if those running El Capitan or High Sierra would download this new version and let me know, please.
It is available from here: lockrattler35
and from Downloads above.
