Info says works on OS 10.8 and up.. Paid the money via PayPal. Installed Sleepless v2.9.0. It didn't work on El Cap 10.11.2 (i.e., MBP still went to sleep with lid closed). E-Mailed developer. Never heard back. Oh well, live and learn! Does anyone have another software solution that works on El Cap to suggest instead? Thank you.

$10? There are multiple free programs that accomplish this task. Also, there is a new terminal command for sleep prevention, it's called "caffeinate" - search for it. Sorry for anyone wasting the $.

I've been looking for something like this for a long time to stop my Macbooks from turning off when the screen was closed! It looks like everything works as advertised on my 2011 MBA / 10.7.3. However, I think it could be so much better with a new mode that is a mix of "Prevent sleep with lid closed, displays will sleep" and "Allow sleep timer" It would act like the first, but also specify a timer so if you forget it too long, it will eventually go to sleep. The timer would start counting when the lid was closed and never be in effect when the lid was open. This way, I can close the computer to carry it around, but if I don't open it after a specified amount of time, it will sleep. I think a lot of people would like this mode since it keeps the computer awake (including network connections) if you're just taking the laptop around your home or office. However, it will sleep after some time in order to save battery power and prevent overheating.
