BTServer causing high CPU utilization

Thanx supertv.

That did the trick - now I just need to remember this, once I might need the BTServer in the simulator.

Found another interesting thing in the simulator having the Activity Monitor present all time.

Once the keyboard shows up, it uses 40% cpu - just by showing the keyboard.

Is this just me and my MacBook or is this as common as the BT Server?

Just received a reply from Apple - they had previously logged this issue under Bug # 10060466. Like I said before I don't think there is a way to follow specific bugs publicly but I can't verify as I'm getting a login error right now. I will post again if I get another update.

Hi guys,

Just want to let everyone know that I have been disabling BTServer service for more than a week;

and the solution is working for me without any side effect.

ankhansen did confirm this as well.

Before this, it was a pain to kill BTServer every 5 min or so.

Hope it helps,

T.V.

I finally figured out how to disable it.

sudo edit /DevIos5//Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0. sdk/System/Library/LaunchDaemons/com.apple.BTServer.plist

There is a 'disabled' key set to false by default.

Setting it true will prevent BTServer from being started.

Hope it helps,

Worked for me as well. Just edit this file using XCode and set the Disabled property to YES.

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0. sdk/System/Library/LaunchDaemons/com.apple.BTServer.plist

I had to set the Write permission to the file and to all its parent folders up to the top one, otherwise the file didn't save.

I ran into the permission problem. I used Finder to grant Read & Write permissions to admin (Administrators) on that one file. But it doesn't seem right to relax permissions on entire folders. My background is Windows (NTFS) so I don't fully understand why Xcode requires that (also TextEdit). I dredged up an ancient recollection of using vi many many years ago, and was able to change the file. I noticed afterward that the permissions on that file I granted to admin have disappeared, don't understand that either.

When my BTServer went out of control, it was often soon after a resume from sleep. I noticed this in the log corresponding to the latest event.

I have the same issue. My mac is 10.6.8 and I'm using XCode 4.2.

Just try:

Go to the Macintosh HD > Developer > Platforms > iPhoneSimulator.platform > Developer > SDKs > iPhoneSimulator5.0.sdk > System > Library > LaunchDaemons directory and then open the plist file from there. Locate the "Disabled" key and change its value from "NO" to "YES".You need to change permission in the file and also its parent folder in order to save the new permission of plist file before modifying in XCode.

Hope this help.

Frankie, this is exactly what I ended up needing to do on Friday after another laptop's fan started whirring like crazy.

My recommendatiopn of renaming the bin is BAD since the console will output many many messages of attempting to lainch the BTServer.

Yeah, I'm gonna recommend against my solution since it spits out a lot of console window information.

It will work in a simple case, but Frankie's recommendation is the best and has complete instructions.

@elguanodev: There IS a way to spot the high CPU usage before the fans start revving: I use MenuMeters. This shows the CPU load in the menubar as a small graph. Launching the simulator usually also raises CPU usage a lot. (2Ghz i7 MacBook Pro) After quitting the simulator, the graphs usually return to normal, but not always. (That's why I am here in this thread, responding to your post :-)

Xcode Developer Preview 4.2 Beta 7 fixed the problem for me.

Just FYI: I'm seeing the problem with Snow Leopard 10.6.8 and Xcode DP 4.2 beta 7 (4c177)

Same problem here on the official XCode 4.2 / iOS 5 release that came out yesterday.

Same here, 10.6.8 and official XCode 4.2.

Same problem here with the GM version, when waking up. Will try the final release.

But you just have to use activity monitor and kill BTServer process. This works for me !

Same problem here on xcode 4.2 w/ iOS5 running on 10.6.8.

It works if I kill the process.

But the problem is that it keeps coming back.

Does anyone know how to disable this annoying BTServer daemon ?
