basically at this point, you are out of luck. without any tracking software there really is nothing you can do.
you might be able to track it through any open accounts that have auto logins but after two weeks, the os may have been re-installed or the harddrive replaced. you can check to see if any of your accounts have been accessed by the laptop since it was stolen and if so, contact the police. do not do any more than that since you could corrupt any info that might be available

Help! My MacBook Pro was snatched out of my car 2 weeks ago! I had not activated firmware lock. Is there anyway of tracing it? Find My iPhone was on and I've set it to lost mode. Whether there is a way to trace my stolen laptop or not, is there reliable software/hardware out there that can be installed on/in a laptop (Mac/PC) that in the event that the laptop is stolen, there is a method to trace and possibly reclaim it? All suggestions are welcomed.
