No worries and you're absolutely right about there being no real solution until Apple comes out with a fix. As a result of some of the other related problems with this release, I installed 8 gb of RAM in my mini server yesterday and ran throughout the day without one failure of any BT device. Before the RAM upgrade it seemed to occur after a wakeup and with greater frequency when the server was thrashing. Te pageing / swap rate under load is now very low and the overall responsiveness of the server is more than adequate for my efforts. There are obviously some major issues with Apple's memory management that should be addressed. The RAM upgrade seems to have circumvented the BT issues for me but users shouldn't have to spend the $50 to get around this problem. And, the folks with MBAs are really caught between the proverbial dog and a fire hydrant.
This summer I installed 8 GB 1067 MHz DDR3 on my MacBook (Unibody, late 2008)
Officially 8GB is not supported
but the hardware is compatible with 8GB (Step 12)
Do you really think that this could cause the trouble???
I don't think and hope so...
That could go either way. Apple does update machine firmware when it rolls out these major upgrades. Some of the smaller "all in one" updates will, as well. Especially if there is a pressing need. I don't think that they would just shut the door on a convenient upgrade of older hardware. There's not any financially motivating reason. In fact, keeping older hardware in the market has been one of Apple's strengths for decades. You only upgrade when you want to. Look how long they supported Carbon executables after moving on to Cocoa. From a purely technical standpoint, if you haven't had a problem yet, it is PROBABLY not a factor now. Also, I can't really see why the effect would be to hose your mouse. There are much more memory dependent Apps.
I know that you are looking high and low for a solution. Despite my banter with H, I'm not going anywhere while people are still having issues. Maybe I can help. Maybe not. My Solution post does actually work for many people, including myself. The remaining issues are concurrent problems, like Len's and the headphones, and Microsoft BT mouse users.
I FLAT OUT CANNOT BELIEVE I'M ABOUT TO SUGGEST THIS, BUT HERE GOES! "...though I suffer the slings and arrows..." Ducking now... INCOMING!!!!!!! you could try installing the microsoft intellipoint for mac stuff, to see if you get any improvement. Okay, I'm still here. The color is coming back into my vision. Heart rate is below 140 now.
My research on the Microsoft users falls into two categories. Gamers, and everyone else. Often, gamers will have issues of "sniper lag," my term, where the mouse has entered idle mode from a lack of activity and the first motion of a sniper moving to correct aim for a snap shot will be missed as the mouse transitions from idle to active. On the other hand, there have been problems with IntelliMouse mice dropping the BT connection in "Dormant" mode. "Dormant" mode seems to be the culpret here. Generally, the mouse will enter it Dormant mode after 10 minutes of inactivitiy, but many gains in battery life are a result of dropping to Dormant mode after shorter periods of inactivity. In an ideal world, the Dormant mode IntelliMouse would reduce only it's sample rate on the optics and not fiddle with the BT connection. In the real world, the BT connection is what eats power, so reducing radio power, sending "keep alive" packets less frequently, and other tricks can have a fairly large impact on battery life. Normally, such tactics will not negatively impact the typical user.
I have begun to suspect that there may be a problem cropping up as Apple has moved to the BT 4 specification. BT 4.0 is the low-power, energy saving spec. It's possible that a very strict adherance to the spec by tweaking the settings of older "pre-4.0" hardware may be resulting in dropped connections. Whether this is due to the Microsoft implementation of the BT spec, or Apple's I cannot say. In any event, that's my thinking on your mouse problem. I'm willing to keep trying as long as you are.
Let me know if you try the IntelliPoint software, and whether it helps.
Hi Cal, back to square one unfortunately. It wasn't 7.5.2 as I reverted back to 7.5.1 and the dissconnect was still present. So I'm back to thinking its something tweaked in 10.7.2 perhaps as you've suggested it has something to do with power management of BT4. I also played around with the radio channels, wide channels etc. of the TM/router and again to no avail. There may be a connection to Time Machine's backups I'm not sure. Pretty frustrating and I'm running out of options it appears. Makes it pretty hard to use CAD on the machine so it looks like I'll be back to a wired mouse for a while. Len
Have any of you tried connecting your bluetooth mouse without the Microsoft drivers? You wouldn't be able to configure your additional buttons and special features, but it would help to know if the Intellipoint code is a factor in this problem.Re: 10.7.2 Bluetooth problems
I dont have the Intel drivers installed, never have, only stock Apple ones.
This guy has the same problem without IntelliPoint Drivers, so they aren't the cause...
Okay, I couldn't remember for sure. You willing to try rooting them out and getting back to the basic drivers?
