Q: New MBP's mac OS Sierra v10.12 doesn't seem my USB connected Samsung Galaxy S6 edge. :(

Does it recognise it if you unplug it, wait a few seconds and then replug it?

I have disconnected and reconnected many times already. Old MBP has no problems. I wonder if this new MBP is defected, but then this German Samsung Galaxy S6 gets power and an external MS USB mouse worked.

Yeah, I used Android File Transfer (AFT) v1.0 (https://www.android.com/filetransfer/ -- last updated in 2012) and then tried Samsung's Smart Switch (http://www.samsung.com/us/smart-switch/) apps. Neither worked. On my old MBP, I only used AFT. I tried redownloading and reinstalling them too.

I did some more testings. It doesn't seem to be app related since mac OS

X/Sierra v10.12 can't see the connected device according to its System

Report's USB details. I compared before and after connecting as shown:

I tried to connect old, updated iPhone 4S and iPod nano 6G with the old

school USB cable and no problems. Is there a special driver I need to

get for Samsung Galaxy S6 edge (from Germany)?

I am still puzzled why the old MBP and its Mac OS X v10.10.5/Yosemite

has no problems. Thank you in advance.

Also, Console and dmesg logs don't show anything about the USB connected Samsung Galaxy S6 edge. They do show connections for USB flash drives and mouse though. Weird.

OK, this is getting weird now. A few times, but I can't always reproduce

it. mac OS Sierra/v10.12's System Report's USB shows a card reader, but

this Samsung Galaxy S6 edge doesn't have a card reader slot that I could

find. Here are the copied and pasted texts:

http://pastebin.com/raw/ZX75tKvc ... However, it says Apple's and not

Samsung. Hmm, is this new 15" MBP defected, confused, a bug, or

something else?

https://www.reddit.com/r/MacOS/comments/57t9g2/new_mbps_mac_os_sierra_v1012_does nt_seem_my_usb/d8wa$

suggested I run kextstat command so I did it in both normal and safe

mode (still had the same missing Samsung Galaxy S6 edge USB connection

problem): http://pastebin.com/raw/iQGRRzSt ... I didn't see anything

unusual. I hope those drivers are correct for Mac OS X v10.12/Sierra. :/

Resetting MBP's SMC, assuming I did it correctly since I didn't see and hear any notifications about it, didn't help as well.

Everyone has no problems connecting their Samsung Galaxy S6 edge to connect to their Macs' Mac OS X v10.12/Sierra with the USB cables? Or is it just me?

Apple support told me to ask Samsung and look for drivers, but I don't see any. I read that Mac OS don't need drivers to connect to Samsung Galaxy S6 edges? I don't remember installing any drivers on the old Mac.

Also, this smartphone's model number is SM-G925F. According to Samsung's web site support. it is not from USA. Region blocked? Is that the problem? If so, then why did it work on my old English MBP and its Mac OS X v10.10.5/Yosemite?

I decided to upgrade the old 15" early 2013 MBP's Mac OS X

v10.10.5/Yosemite to mac OS Sierra/v10.12 since I needed to return it

soon. Since my new 15" MBP replacement mostly works, I might as well try

to reproduce it on the working old one. After upgrading and rebooting, I

logged back into my usual administrator account. I USB connected my

work's SIMless Samsung Galaxy S6 edge and retried. It worked perfectly!

I checked mac OS' System Information's USB details and saw it listed:

I wonder why the new 15" mid-2015 MBP doesn't connect to it. Here is its

System Information with the connected, but missing Samsung Galaxy S6

edge: http://i.imgur.com/iDRDnIt.png ...

It looks like Apple changed its USB setups like removing USB2 in its 15"

MBP (Retina) between early 2013 and mid-2015 models in terms of USB? I

wonder if the new MBP's USB hardware is defected or something. Are there

software USB testers?

I found out this SIMless Samsung Galaxy S6 edge is global and not with a US carrier. According to my former boss who got me this Android smartphone to test with, it was probably ordered online like Amazon from Germany. That explains why its default language is in German and Samsung's technical support says to contact a non-US company.

I wonder if Apple region blocked it? If so, then how the early 2013 MBP worked fine? Did Apple make it region blocked in its mid-2015 MBPs?

I installed a clean mac OS Sierra v10.12 into an external USB3 HDD and then retested it. Same problems. Now, I am thinking this new MBP's USB hardwares are defected or something.

OK, my computer friend figured it out earlier. It was the white USB

cable that came with this Samsung Galaxy S6 edge. Its micro-USB male

plug had a missing pin #4 as shown in

http://img.weiku.com/waterpicture/2011/10/22/8/Symbol_LS2208_barcode_handheld_sc anner_USB_cable_634592271482806464_1.jpg

... We tried his Android phone and it also failed. We tried a new longer

cable from Monoprice, and it worked. He analyzed the micro-USB male

plugs to compare both cables.

It is so weird that the new MBP (mid-2015) would reject this cable! :/
