Here are some details.
I did try to pull the logs. I installed DJI Assistant and it connected to the mavic pro. However, when I clicked "Flight Logs", it just hung as it tried to get a list of the logs. The mavic fan did go on and it got loud but it never actually gave me a list of files. After about 15 minutes or so, I just disconnected the mavic from my computer. I tried it again but the same problem.
I tried connecting the mavic pro remote to my phone but there was no camera picture. It did connect successfully though.
When I sent the box to the buyer, it was brand new and pristine with the seal intact. When I got the box back, the seal was broken (not a problem since he said that he opened it) but the box was all dirtied up like it had been in an auto oil change shop. I questioned him about it thinking that maybe he didn't send me what I sent him but he said that he is a mechanic that owns a huge repair shop so he did get the box dirty and apologized for it. He was fairly cooperative the entire time but his story that he's sticking with is that he received it, broke the seal, opened it up, and basically found what he sent me (an old looking mavic pro that's all used, scratched up, etc.). He said that he tried to fly it but it kept falling down (maybe a motor issue?).
The receipt from apple did not have the serial number on it.
The box was also missing a few things (it was missing one of the extra props, one of the extra cord adapters, some of the small boxes that stored the usb cable and instructions, etc. He claims that it came that way.
I didn't think the apple store would take it back but I took it to the store and told them that I bought this one but the camera doesn't connect properly to the phone (can't see a picture on my phone when connected to the RC). They looked for the serial number but also noted that it wasn't recorded on the receipt or their records anywhere. They opened the box and visually inspected the mavic pro (took it out) but did not inspect the RC or check for the extra props or inspect the charger.
The employee scanned it, scanned my receipt, and accepted it as a return. She didn't seem to know anything about these drones though as she first asked if I wanted a replacement. I said that I'd like one but they probably don't have any in stock. She checked and sure enough, there were none in stock.
I am happy that they took it back. If I ever get any more from the apple store, I will be sure to open up the box on the spot in the store to verify before taking it home. I will also sell locally only. eBay fees were way too high. I sold this one for $1400 but ebay took $140 and paypal took around $35 and shipping was another $25 so I only cleared around $1200.
The return shipping that this guy used was crazy. He sent it fedex overnight priority (or something crazy like that) and it was $130! He offered to split it with me (I told him that I'd pay for him to return it to me but didn't specify what to use, etc.) so I guess in the end, I'm out $65 but that's fine.
I was definitely curious to see if there were any flight lots from before 12/10 (when I picked it up at the apple store) or after 12/13 (when the package arrived at his location) but because DJI Assistant just hung, I was not able to pull flight logs from the mavic.
When this guy first messaged me, my initial reaction was that this guy was a scammer either trying to get a free mavic (will send me back nothing or a box of rocks) or he got it, crashed it, and now wanted a refund. It's odd because as this played on, I believe him more and more and think this might really have been an Apple issue.
