Bluetooth lags on new Mac Mini w/ Wireless keyboard and Magic Trackpad

I have a similar setup: Mac Mini that's being used as an HTPC. It's connected via HDMI to my LED TV. I recently purchased the MTP to complete my setup but it's been starting to lag. I've changed the batteries (even though they were reported as being 85% full), checked to the output refresh rate (which was at 60), I've disabled and enabled bluetooth, removed and re-added the MTP, in brief I've tried quite a bit to resolve this issue to no avail.

Anyone come across any definitive solutions? And no, telling me to buy a bluetooth dongle (as some have suggested) or a new mouse is not a solution.

Guys,

I just bought a Mac Mini 2011 i5 and the blue tooth wireless mac keyboard, using a logitech mouse temporarily (I wasn't sure if I liked the apple $70 mouse...) and I am having the exact same problems. I don't really see wifi interference as a valid reason for the problems; as I type this (I generally type at 60-70 wpm) it is working perfectly and the keyboard is pretty nice.

However, 4 minutes ago when I was signing up to post a reply, the lag and aggrivation it causes is unbelieveable. Same issue with the logitech mouse, lagging and creating issues. Even the mini's performance of a simple task such as opening firefox is pretty intermittant.

I'm loving OSX but considering that this mac mini and it's accessories are not up to par. I bought the Mac for it's reliability and so far the intermittant performance of the Mac itself and particularly the blue tooth accessories is not going to cut it.

I just got a 2011 Mac Mini, but I got a Wirless mouse and Wirless keyboard with USB transponders. I was not about to pay over $70.00 for the Apple keyboard and mouse and trackpad. The LogiTech K250 is a pretty decent keyboard. The LogiTech mouse is awesome. You do have to go through steps to identify the keyboard in the Mac Mini, but it is worth it from what I have experienced so far. It is also much much cheaper.

Update- the bluetooth problem is gone now that I have set up a 23'' monitor. I was previously using a 120'' cinema screen through an optoma projector. Apparently that screen size did not go well with the Mac. That's bad news for buyers who think they're going to use the mini as part of a home theater.

Still no solutions? I can barely use the trackpad anymore and without screen share it would be impossible for me to be able to control my mac. I don't want to get a new mouse but this is getting frustrating.

I use my Mac Mini with a 40in HDTV using a DVI to HDMI connector and it seems to be working so far. I had to do some adjusting using the Underscan in System Preferences to see the menu bar, but other than that it is ok. I recommend wireless keyboard and mouse with USB transponders. So far the Mac Mini works great as a home theater PC. I bought it because I wanted a new desktop computer and this one has that capability as well as HTPC capabilities.

I had this problem - strange jerky bluetooth mouse behaviour with my Magic Trackpad. I found it to be caused by the Wi-Fi signal. When I turned off Wi-Fi, the issue went away.

To resolve, I changed my wireless channel from 11 to 1 on my router to change the frequency of the Mac's wireless conversations. Not had the issue since !

THAT FIXED IT FOR ME:

I had the jittery keyboard with lots of repeated keys. I was using CHANNEL 8 on my wifi.

So I did and experiment (based on MitchF's post). I switched back and forth between CHANNEL 1 and 8 and typed a few words in TextEdit (via BlueTooth Keyboard) to see if there was interference in Channel 8.

HOLY COW !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

INITIALLY ON CHANNEL 8

Still having this problem Apple... no fix??

(The above like took over a minute to type correctly. Unfortunately not exaggerating.)

Keyboard has disconnected 8 times in the past hour.

Changed wifi channels and TV to 60Hz. Nothing.

Two solutions:

1). 2.4 Ghz Logitech keyboard n mouse. My solar powered Mac model works great!

2). RC Trackpad on you iPad ... Fantastic, keyboard and mouse in one gizmo. Love it, My mini is hooked up to my TV, and way in the back of a cabinet, can do everything on my iPad from the couch

So effectively what everyone is saying is that there is no "real" solution short of changing peripherals altogether and I concur. I had this problem and quickly sold my trackpad on CL. I got back quite a bit for it and invested it in a Logitech keyboard trackpad combo. It's a great device. Small light and perfect for an HTPC setup. I think it's the K300. Snatch one up if they're still available. And Remote PC for iOS is also a good alt and in life's VNC as well.

I don't think that what everyone is "effectively" saying. If you read some of the responses, some folks have had luck with the NTSC/60HZ setting and/or changing the WiFi channel.

I've been experiencing this issue with my Mac Mini. My router sits right next to the Mini, so I suspected the WiFi issue. So far, after changing the channel on my router, things seem to be going ok. We'll see how it goes.

This is likely a different issue, but similar symptoms.

New Mac Mini with bluetooth mouse that lags ridiculously and often disconnects.

Not a WiFi issue, but found this paper about USB3 interference with bluetooth on another thread.

I moved my keyboard USB plug down one slot and the issue is much better.

Worth a try.

Further to the USB3 issue: http://support.apple.com/en-ca/HT203729

Try moving your USB3 hard drive away from the Mac and your mouse.

I had the same problem with my macbook pro that I've just upgraded to yosemite. Using a magic mouse and apple keyboard. Seems to be better when wifi is disabled.

Mac Mini on OS 10.10.4 (Late '12 SO-DIMM RAM and a single DisplayPort connection) with the EXACT same problem:

1-It is intermittent and entirely unpredictable.

2-Sometimes for a few minutes, others for hours, the latency is terrible.

3-None of the fixes posted so far have worked.

Impact- The keyboard is somewhat usable if you just need to log into something, but the trackpad is useless, I can spend minutes trying to every try to get the thing to "land" on a specific button, icon, app, etc.

FIX: I recently switched to a new AC/backwards compatible wireless router. My mini has only N so I put that on my N Network and my devices that support AC to their own. After trying every posted idea, I had my N mini join the AC network instead (even though it is still stuck at N bandwidth) and my problems stopped immediately and have not returned. I cannot explain this with my limited wireless knowledge, but it worked.

I would think my neighbors (about 40 show up on my Mini - 36 still N) would cause the same problem, and my Mini being connected to one less N-labeled network wouldn't make any difference if there was simply too much interference. I think that there is an actual hardware or driver problem on the Mini that causes N and Bluetooth enabled devices (maybe the Mini and the Keyboard/Track Pad both happen to be more susceptible. This would explain the greater volume of people with this 2+ device problem).

Please reply if you try this fix and find that it works.
