    Hey guys,

    I just picked up an iMac Retina that came with the Apple Bluetooth mouse. This thing disconnects and reconnects multiple times a day and seems to have a bit of lag.
    In all fairness I've been using a Wacom tablet for years, mostly with the pen, and some with the Wacom mouse. I never noticed any lag like this.
    Any suggestion would be appreciate it.

    Do you have any USB3 peripherals attached to your mac? It is a known issue for USB3 to interfere with the bluetooth signal, I've mainly heard it with the mac mini, but i don't see why it wouldn't effect an imac as well?

    I've got two Magic Trackpads and one Magic Mouse for my Mini Server and rMBP, and I also use an Intuos Pro with my rMBP (I use a Trackpad or Mouse with the tablet when I'm drawing/drafting. Really.)

    Agreed with mattluke on the USB3 cable thing. USB 3 cables that aren't properly shielded can wreak some havoc with BT devices - I've gone so far to buy some nice shielded cables and put the cheap cables in a box.

    Also, when I'm using my tablet in wireless mode I put the USB dongle on the opposite side of the rMBP. One more - I use a Plantronics Edge UC (which comes with a BT 4 LE USB dongle for a PC/Mac for VOIP or dictation); if the iPhone rings and the Edge is connected to it, the Edge UC "lights up" my workspace - sleeping Macs wake up, or a in-use Mac goes haywire as in the cursor goes all over the screen and I've had to log out and back in, so I keep the Trackpad/Mouse as far away from the BT USB dongles and BT headset, and turn off the headset if I'm not going to use it.
