This may or may not be relevant in your case? But I use both PC and MAC side by side at work, all networked together. I've got Adobe CS6 Design Suite installed on an iMAC. Which, to no surprise, is used for media graphics work. Files are shared between the PC. Think of it like a local Dropbox.
The problem I have on the PC is that its set by policy to sign out the user with no activity every 15 minutes. Which is especially annoying having to constantly log back in when I'm working on the iMAC. The policy is set on the enterprise level, so nothing I can do to change it.
Yes, there are apps that move the mouse one pixel at a set time to keep from logging off or going to sleep. But my solution was to create a small 100K video file that just loops constantly in the player. No audio. Just a still image, minimized to the task bar. I've set the video file to automatically play on WIN startup.
Windows never logs off or goes to sleep as it senses a user activity. Specifically, a video file playing. One that I don't actually even watch. Simple solution, and safer than trusting an third party program, which could be doing more than just keeping your system from going to sleep?
