MacBook Pro Retina 15" stuck on load progress bar

Hi there. I can't get my MacBook to boot properly.


SYSTEM: Late 2015 model running El Capitan 10.11.16


PRE: Last thing I did, before this happened (a day before):


* I connected my Canon printer via USB (like I've done many times before)

* In printer settings, I shared the printer so a friend could print through my computer over wifi.


It was a success. No problem. I turn off the printer, pull the plug and close the MacBook.


PROBLEM: Today I open my MacBook and the mouse and keyboard are unresponsive.

Notifications popup, e-mail etc.


I can't do anything so I hold down the power key until it shuts down.


When i try to turn it on, it never finishes loading.


I'VE TRIED:

* Booting to safe mode and recovery mode. Neither works.

Safe mode looks just like normal boot. Nothing indicates that it's safe mode.


Recovery mode will only allow me to boot from that one hard drive. Internet recovery mode does it's thing, downloading etc. Then tries to boot and gets about 80% of the way (loading bar)


* Safe mode / Verbose:

It pauses on some "VBoxFldDrv" and "VBoxAdpDrv" before continuing and ultimately stopping after writing

"ignored is_io_service_close(0x10000046a, IOHIDParamUserClient)" to the screen.


* I've tried different booting options with the printer and mouse connected.

* I've tried clearing the SMC and PRAM or NVRAM or what it's called.


* Single user mode:

Works great. Although the last verbose lines say something about "IOBluetoohUSBDFU::probe" and "AppleUSBMultitouchDriver::checkStatus". And seem stuck there, but it isn't, because when i press enter, the "localhost:/ root#" command prompt appears.


I've run "fsck -fy" and there are no errors on the harddrive.


WHAT NEXT?

I don't know where to look for further clues to what causes this problem.


* VirtualBox is messing up the system because I shared the USB printer?
* Something to do with USB and/or bluetooth?

* The only thing working is single user mode


Thanks in advance for your help!

UPDATE: FIXED!


Left the computer alone over the weekend and then tried fixing it again today.


I turned on the printer, connected it to the computer, but now a different usb port.


Turned the computer on and lo and behold - It boots normally!


The problem and solution in it's entirety:

1) connecting the printer, sharing it on the wifi, unsharing it again and closing the macbook

2) Upon opening the macbook, keyboard and trackpad unresponsive - Need to hard reboot.

3) Computer will absolutely not finish loading/starting and wont boot in any modes. All sorts of tricks tried and nothing helps. Even tried connecting mouse and printer again.

4) CONNECTING printer to the *probably* same usb port it was connected to in the beginning, allowed the computer to start normally.


Strange. I hope this helps someone else.
