I updated to Mac OS 10.14.6 and had an issue with Caffeine not working so I looked and found Amphetamine. It was a bit confusing but the main reason I went back to Caffeine was my MacBook was warm after a (couple) night(s) of no use. I put it to sleep and went to bed. Mac Fans Control said the Cores were at 70 degrees celcius instead of 40. I'm not sure what Amphetamine was doing, maybe I had a setting off or on.
I love this app, but the only feature I feel it's missing is the ability to permanently add applications to the white list. Otherwise, the features are rich, and it's very well designed and thought out; I love it much more than any other similar app I've used in the past. My only other suggestion is: charge a few dollars for it; it's worth at least $5. Give me an app white list that prevents sleep, and I'll update to 5 ⭐️. Great work!
Waiting to see if i can get an apparent permissions drawback overcome. My system won't let me choose the external backup drive used for time machine to stay awake (because it causes my whole system/imac to stall/lag/freeze .... i guess it's the external drive, that's what i've analyzed it to so far).
One of the positive/different things about keep drive spinning is it allows me to use admin pw to force KDS to choose the external drive. i filed a support request w/ amphetamine cuz i would like to try it and see if it's indeed better as so many reviews say. Thanks. will plan to update once I find out.
UPDATE: Boy that was quick! They responded almost immediately and told me to do this:
Try creating a new folder at the root of the drive for use with Drive Alive. Then, select the folder instead of the root of the drive.
It worked! I named my emply folder > Amphetamine Keep Alive My Drive, which i was able to choose in Amphetamine preferences > Drive Alive.
So, that barrier was defeated (easily) and now I'm going to be testing it and comparing experiences. Will review later.
Really nice free app. A must have if you need preventing sleep computer when he's in monitoring state. Ex: When i'm djing with Traktor, almost everything is done under midi controllers. Don't need to touch the trackpad or keyboard for bringing back my monitoring screen. Amphetamine last for all night live session. And it's legal ;)
Works perfectly, much better than any other similar utilities I've tried, including caffeine and jiggler, not to say that they are not good ...this is better, and has the option to allow the screensaver and display sleep to work, thanks dev
