Further config items:
- Safe-Boot (hold shift-key down when booting)
- Create a “Default Everything” account.
- Disable bluetooth (is enabled by default) and also disable its Discoverable property.
- RightClick on the bluetooth icon at Mac’s top-right “system tray”
- Which graphic card (GPU) is in use? According to “About This Mac”, it is the lower-powered 9400M instead of the higher-powered 9600GT (both are NVIDIA GeForce). How do I change it to the higher-powered one?
