I used to work at a place that had several Macs in close quarters. Sometimes when I was working on the Mac Pro, someone else would work on the Mac Mini and every once in a while, the mouse on the mac mini would start moving the cursor on my Mac Pro. The mouse that they were using was a Magic Mouse, while I was using a WIRED Logitech mouse. At that particular time, this was a nuisance obviously since I didnt want my mouse to be moving... however, I'm trying to replicate that function at home but I can't seem to get it to work. Now, I'm not exactly using the same hardware, but the concept is the same. I want to be able to move the cursor of two computers simultaneously with a single mouse. In an attempt to get this to work, I purchased a few Bluetooth usb receiver and a bluetooth mouse, but I can't get it to pair with multiple receivers. Does anyone have any information as to how I can achieve this? Is it hardware specific? The Mac Pro had a built in bluetooth card obviously, and I know for a fact that it was not done over the network... it had to happen over bluetooth. Was it a matter of duplicate bluetooth receivers in both machines and the mouse broadcasted to both? I'm so frustrated right now because I can't theorize how it worked to replicate it.
