None of my Bluetooth peripherals are working well with my brand new 15-inch 1.5GHz.
They all worked fine with my 12-inch, and my Mac mini.
Mouse lost any sort of precision.
Keyboard randomly drops connection, or stalls, then dumps, or repeats random keys for 20 hits or more.
I tried resetting the PMU, pairing/unpairing, turning off/on, fresh batteries, no new sources of interference, etc. Pretty much everything I can think of. Since it works fine for s few moments after a fresh restart, I doubt bad BT adapter but what else.? I really don't ant to have to send it away.
Trying to mainly use:
Apple Wireless Keyboard
Apple Wireless Mouse
and/or
RadTech BT500 mini Mouse
Bluetake BT510 Mouse
Bluetake BT400 G5 Bluetooth Headset
All within one to three feet of range.
