Very useful utility - replacement for the older Caffeine app

I started using this app about a year ago as a replacement for Caffeine. I needed more control over when sleep prevention would start, stop, etc. This app does all that and more. My primary Mac is a laptop that I use for programming and remote database work. I find Amphetamine essential for keeping the laptop from sleeping and thus killing remote database connections, VPN connections, and so on. I could go into the Energy saver preferences and tell it to never sleep, etc., but I want to leave these higher level settings alone. Amphetamine allows me to override these whenever I need and with much more precision.

One feature that I am not able to fully use in version 3.0.3, is the app trigger. This is where you can create a rule that says "while 'the specified app' (Safari, etc.) is running, don't sleep". This works well for regular applications, but I was trying to have it see a daemon type process. Even with the option to have it show more than just interactive processes, it doesn't show these background type processes from non-Apple applications. This is really a minor nit pick though. I think that if the app showed you all the processes running on the computer, it would likely overwhelm the average non-technical type user.

Apple restricts what processes sandboxed apps can see, unfortunately. Otherwise, I’d happily implement a ridiculously long list of everything running on your Mac. ❤️

I love it! Very useful.

I honestly love this application. I’ve been using it since Caffeine was discontinued. At first, I thought it was a bad replacement but it turns out to be more fun and customizable. I love that I could change the icon and sounds. My only peeve is that the notification sounds aren’t working for me but I’m not sure why. I highly recommend it to people. I set it at work so I can work remotely without having to manually change my Mac’s system settings.

Edit: Per comment below by the developer, I spoke to him about the notification situation and I’m kind of disappointed that the sounds are completely removed. I undertsand that the menu bar icon indicates whether a timer is active or not, but assume you’re not sitting at your computer and you don’t see the icon, then the sounds would indicate when your computer would go to sleep. This applies to people like me who manually activates timers. Although it says on the changelog that it will be removed and no longer implemented, I really want to make it a suggestion to bring back the sound effects. I took off 1 star for it because it misled me, considering the options for notifications and sounds are still in the app, but no longer functions the way it used to. Again, this is a free app that is made very well so it’s probably a minor complaint to most people.

Great, but not sure how "While File is Downloading..." works

First off, I want to say that it's really stupid that Apple took away the separate display sleep and system sleep controls in the Energy Saver preferences. I'm thankful something like this exists.

As for the issue mentioned in the title: that option requires the user to select a file. When I use Firefox, downloads appear as two files: one file has the correct filename, but is 0 KB in size, while the other contains data, but has .part appended to the end of it. I'm not sure which one to open, or if either one will do.

Also, about 3 versions ago, when using Amphetamine on High Sierra, I set it to stay awake indefinitely (but allow the display to sleep), and it still went to sleep (my download was interrupted). I've taken to going in to Energy Saver and preventing the display from sleeping, then turning the display's brightness all the way down, while downloading large files. I haven't tested whether or not I still need to do that. I'm wondering if launching Energy Saver after starting an Amphetamine session overrides some of Amphetamine's session settings? Or if I need to turn off the password requirement when the display sleeps?

❤️ Contact support through the app. Happy to answer these questions.
