Q: 1. Will it work on dos base computer ?

Q: 2. me and my movie

A: I have the very latest Mac OSX 10.13.4 and the Kensington software only allows the 2.4GHz receiver to be used, Bluetooth is not available. In addition, the 2.4GHz receiver has trouble during wakeup if the Mac has been 'sleeping', many times my receiver needs to be unplugged/replugged so the Mac OS can find it again, this is a pain in the neck. I have called Kensington Support and all they could suggest was to put new batteries in the Expert Mouse, of course that made zero difference. I have been a USB Expert Mouse Trackball user for over 10 years but this model does not work right with Mac's. The Trackball software and Expert Mouse are flawed, don't waste your money.

Q: 3. Will it work on dos base computer ?

Q: 4. WIll Trackballworks be supported over Bluetooth on Mac OSX 10.10+ eventually? I was disappointed to read that this product currently cannot be used over bluetooth on Mac OSX, as specified you must use the 2.4Ghz receiver. Seems to me this should have been disclosed on the product details.

Q: 5. I wasn't signed in when I asked my question. Been using a wired Expert for 30 years. Purchased a Blue Tooth wireless when my wired died. It wont pair with either of my HP laptops one is running Win8.1 the other Win 10. Whats a girl to do?

A: Hello. I know, it seems that turning the mouse 'ON' and flipping the switch to 'Bluetooth' would be all that you need to do to pair. However, you also need to hold down all the mouse buttons, simultaneously, for about 3-5 seconds. After that, a blue light will start flashing near the bottom of the mouse, and the entry Expert Wireless TB should show up in your available Bluetooth devices list for pairing. There is a very poorly designed, and difficult to read, graphic on the bottom of the mouse illustrating this. Good luck pairing.
