Q: El Capitan shutting off USB power on MacBook Pro?

Since upgrading my Early 2015 13" Retina MacBook Pro to El Capitan from Yosemite, I have noticed that it shuts off power to the USB ports when it's asleep. I know for 100% certain it didn't use to do this, as I travel constantly for work and use my MBP as a convenient charging hub in hotels. Plug everything in, go to sleep, wake up and everything is ready for the day's meetings/flights.

 

Since updating on Wednesday, this isn't happening. I'll plug all my devices in and they will get a little top-up, but in the morning the MBP is fully charged and my Watch/iPhone/iPad/whatever are run completely down instead of fully charged.

 

I have already done an SMC reset. Anyone else seeing this or have any suggestions?

MacBook Pro with Retina display, OS X El Capitan (10.11)

    I noticed it already when using the Beta.

    left comment on it to Apple.

    probs for charging external devices as well as power feeding for external gear.

    Stopped using it, and returned to Yosemite.

    hoped it was solved in el capitan...

    still a lot of probs. if you are using Logic, don't upgrade!

    meanwhile, while upgraded, lots of problems to restore Yosemite from backup.

    so be very sure if you do want to upgrade... there's no Yosemite 10.10.5 link to downgrade anymore

    Same here! MacBookPro Retina.

     

    My iPhone won't charge over night anymore. As soon as I wake up my Mac it starts loading again...

    Same issue here on a mid-2014 iMac -- I've routinely used it to dock my iPhone & Apple watch overnight, but they're no longer charging

    Yeah, it's getting to be a bigger and bigger problem for me. Been watching for updates daily and still nothing - really hope this gets worked out. El Cap has otherwise been a pretty solid, if mostly uninteresting release.

    I wonder if that is why this is happening? El Capitan disconnects usb drives when sleeping

    It sure does look like it could be related. There are also reports of a whole plethora of USB related issues with the El Cap betas out there. I have to imagine this was a known issue that just couldn't be fixed in time for release - and hope that there will be a fix very soon.

    Not only do I have this problem but when my macbook air (Mid 2011) is awake, my iphone 6 is only charging at 500mA rather than the 1000mA that should be available from the port.

    These are all symptoms of the same problem; low power to ports, ports shutting off, devices randomly disconnected - there is an issue in the new USB driver. Looking back over the feedback during the beta period, it appears this was widely reported but just not fully fixed at GA.

    I’m not seeing that on my 2011 MBA and iPhone. I tried both sleeping the computer while the iPhone was connected and connecting the iPhone with the computer was asleep (closed) and in both cases the phone began charging.  I’ll try to remember to check my newer MBP this evening.

    Similiar issue for me.  Iphone6, iPad Air and Apple watch all fail to charge on 2011 mid year MacBook Air with display closed where all previously charged under Yosemite.  I reset SMC and PRAM/NVRAM but neither helped as well.  Disply open all charge fine.

    Does anyone know of any workarounds besides ensuring the macbook doesnt go to sleep ?

    So far, that's all I could come up with.

    Having the same problem as well.

    What a frustrating experience.

     

    El Capitan is the first Mac OS X upgrade that I consider to be worse than the OSs that came before.

    So many bug, so many features taken away... Apple is slowly becoming a terrible company like its competitors. They are catching up, if not surpassed.

     

    Every new update since SJ death shows signs of unfinished and not so grade upgrades.

    Same thing also applies to the Buggy and terrible upgrade for the iOS as well.

     

    But coming back to the subject, my USB port also stops charging after it goes to sleep with the lit closed. Sometimes it comes back charging, but stops a little after. What a terrible experience to wake up and see all your devices with low battery level.

     

    I find it beyond comprehension for a company so big and with so many know-how accumulated, money and talented minds to release a "finished" product with such an amateur bug. Seriously, this is a more than 15 years old OS, you would at least expect a company like this to keep the USB driver working after all, right? What a joke.
