I've read here that Apple computers from mid-2011 should support BLE (Bluetooth Low Energy). Is there a way (perhaps using the command line) to check if the device and the operating system supports BLE?

Find and select Bluetooth. Check the Bluetooth Low Energy Supported line. If that line says Yes, your Mac computer supports Bluetooth Low Energy. If that line says No, your Mac computer does not support Bluetooth Low Energy and will not be compatible.
This allows Android apps to communicate with BLE devices that have low power requirements, such as proximity sensors, heart rate monitors, fitness devices, and so on. To check if your device support Bluetooth Low Energy programmically, check (getPackageManager(). hasSystemFeature(PackageManager. FEATURE_BLUETOOTH_LE)).
Click the System Report button. Under the Hardware tab, select Bluetooth. To find the version of Bluetooth on your Mac, find LMP Version in the list. If the version is 0x6 or higher, your Mac is compatible with Bluetooth Low Energy 4.0.
In the Mac OS X Terminal app, you can type the following:
system_profiler -detailLevel full SPBluetoothDataType | grep "LMP Version"
If this command outputs >= '0x6' then Bluetooth 4.0 is supported and thus, BLE is also supported.
