Apple laptop overheats when running iOS 5 on iPad or iPhone Simulator

Here’s ANOTHER overheating bug in Apple’s OS X.

This time, it’s the BlueTooth simulator built-in to the iOS Simulator (used every day by iPhone and iPad developers). The iOS5 version of the simulator has this crazy BT demon (process “BTServer”) that will sometimes – for no apparent reason – take up 100% CPU usage and melt your machine.

Solution:

  1. Open terminal
  2. Type: sudo vi “/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/System/Library/LaunchDaemons/com.apple.BTServer.plist”
    • NOTE: the inverted commas are required, it seems
  3. Enter your admin password for the machine (the file is locked to all except admin)
  4. Use vi to change the 8th line to: <true/>
    • NOTE: the line immediately above should be: <key>Disabled</key>
