Find My iPhone will not find my MacBook Air (10.9.1) Unless I boot in safe mode. I spent hours looking for a solution I spent 2 hours at Genius Bar - no solution. -boot safe, run disk utility/repair/permissions etc. etc...... -turned off all login items etc. Should I just start from new and reinstall everything? I am not clear how Find My iPhone will work with a MBA. If it goes into sleep mode with a password login: Will it still connect to WiFi and be located?
