I have just taken delivery of a Magic Trackpad (I like the way it works with Logic Studio), but the BT connection with my 2009 Mac Pro is very intermittent. I can't seem to maintain a connection for more than about 10 minutes. This is the first USB peripheral I have used with the Mac Pro (I am using the wired keyboard & a Logitech Mouse) so was blisfully unaware of the often reported Bluetooth problems with these machines. The computer is under my desk, and given the content of all the threads I have now read about these issues, I am not sure whether to even bother calling Applecare. I am thinking I might just order a Bluetooth dongle and have done with it. Can anybody recommend a good one that is likely to work well with the Mac Pro? I am in the UK. If anybody has any helpful suggestions that would mean that I can avoid having to get an external dongle, please do let me know, however I am aware that this topic has been covered before so I don't expect people to repeat themselves unless they want too!
