I am having a similar issue with my New 13" MBPro 2016 w/touchbar, 16GB RAM, 1TB SSD. Crashes with both Time Machine and Carbon Copy Cloner. I have tried multiple external hard drives, multiple USB-A to USB-C adapters and hubs, but each time the backups appear to proceed normally for about an hour and then the computer freezes and crashes.
 
Hahaha! :) we nailed it! Thanks for the confirmation. I tried to send the file to Apple but they do not accept any files by e-mail and there is no web site that I can drop it. I arranged another phone call for wednesday. I will ask for the method of file transfer then.

Cheers,
Riza
You should be able to attach it filing a bug report. I have done that several times.
 
I am also experiencing this issue. I have an 2x8TB RAID1 enclosure connected by USB-C (via a USB hub). Time machine has failed twice now. I contacted Apple Care online and one of the steps he suggested was resetting NVRAM and SMC. I am reluctant to do that because I think it has nothing to do with the issue? Has anyone tried those steps? I see one or two people claim a fresh install has worked for them -- should I try that? I'd really like to start backing up my stuff.

Also, are you people all having trouble with encrypted or non-encrypted backups? For me, I've been doing encrypted backups.

My machine will crash, and then if I enter the time machine password, it will crash again. I cannot enter my time machine password without my macbook immediately crashing.
Setting up a clean install does not change anything for me. NVRAM and SMC advice ist like "I have no further idea...", so some people tried without success. My Time Machine backup was not encrypted btw.

I performed the SMC reset to no avail. Apple Tech Support has asked me to do a clean install.. I know it won't work, but I'll do it anyway to drive home the point that this is a problem on their end.

In my twelve years of having a Mac this bug might be the worst I ever had. And Apple does still not acknowledge that they are working on it and no major news site or blog made a story of this. Waiting one more week until I return this otherwise beautiful machine...
 
I'm returning mine on Thursday morning if I don't feel like a resolution is in the works. Having their tech support tell me to reformat the machine is not progress, especially in light of all of us with the exact same issue. I even set her a video I made showing the lead up to the crash, and the aftermath.

I'm having the same problem. My 13" macbook pro with touchbar crashes when using Time Machine trying to backup to an external drive. I opened a case last week with Apple but no response. I'm about ready to return the machine and go back to my 2012 macbook pro. It worked like a charm..
 
Hi everyone,

I'm already on my 2nd MBP. Picked up last Wednesday and swapped it for another model 2 days later after experiencing crashing while my laptop backs up via Time Machine to an external HD. Computer freezes up during data transfer and refuses to acknowledge my inputs. Then crashes and restarts itself.

This is now my 2nd laptop and I'm experiencing the exact same issue. Weird thing is, I was able to do my initial Time Machine backup with no problems.

Anyone else experiencing this?

Yikes, I just started hitting this with the time capsule. The first backup went fine but subsequent backups are failing on the TB MBP 15".

Btw, I'm on wifi and am connecting to the time capsule via the wifi connection.

UPDATE: After the first few crashes, this is no longer an issue now. Last few backups have been successful and some were during power nap. Not sure what changed.

OK, I have the failure when backing up to a USB-C connected drive (tried 3 different drives, different makers too) as I stated earlier. I have now successfully backed up via TM to a Western Digital NAS. It of course took longer pushing 300GB through the network, but it worked fine and has been updating on demand without a problem. Thus, the issue clearly resides in the USB-C ports on the new MacBook Pros.
 
I have had freeze issues when doing a Time Machine backup on a Synology NAS. So it might be at least two bugs, USB-C and/or Time machine, but using USB drives with just plain files also leads to crashes after a while...
 
How is this not getting any attention yet other than this thread??? Is there a way to contact the MacRumors editors to put it onto the front page and hopefully start a snowball affect that forces Apple to start paying attention?
 
Hi folks,

CCC author here. I don't have a lot to add to this, except that we've also received a barrage of these reports from users with these new laptops. I'm hoping this is a USB driver issue, not a hardware issue, but that's a tossup at this point. It doesn't appear to be related to any specific file copier, though, so I'm not sure there's anything we can do to work around the matter while awaiting a fix from Apple.

It's imperative that everyone provide data to Apple that they can use to gauge impact of this issue – every engineering resource they spend is driven by impact. But before you open a support request with Apple, I'd recommend that you do the following:

1. Quit as many applications as possible
2. Reproduce the issue (i.e. run a backup task, copy files to the external disk, etc.)
3. When the system restarts, open the Activity Monitor application (/Applications/Utilities)
4. Choose "System Diagnostics" from the gear menu. This utility will take several minutes. When it's complete, the Finder will reveal an archive of the data that was collected.

The file that's generated is huge (173MB on my test system), so there are logistical issues getting it to Apple. Apple has ways to collect that file, but if you can toss it into Dropbox and present them with a URL, that might be easier and require less time on the phone with Apple.

Have the make and model of your attached storage device and any adapters handy as well, then open a support request with Apple (Twitter: DM to @AppleSupport, or https://support.apple.com/contact). Explain that you have a new MacBook Pro, that it crashes when copying files to an external device, and that you have a system diagnosis report that you can share.

And then let's hope that they have all of the information and impact they need to address the matter quickly.

I've opened a case with Apple. They're aware of the the issue and are collecting as much data as possible. Please report the issue to Apple Support if you're experiencing it.

btw..I was able to successfully use Time Machine to backup 100+ gig to my Time Capsule over the network (wired) but it still crashes when I change backup drives to an external USB drive.

What ethernet adapter are you using?

I have had the issue with both Time Machine and CCC.
I have mixed feelings knowing that Bombich is having similar problems...
Makes me feel better that it is not just me but still wish it was not happening.
Supposed to hear from engineers sometime...

Just posted a link to this on Reddit. Hoping it might start to get some attention now that Mike (CCC author) has weighed in.
 
Here's my update. So apple support wanted me to reformat my new MBP and following the reloading of 10.12 from the network, perform a TM backup. I figured this would work, for the size was small (4GB), and crashes seem to happen when 200GB or more had transferred. As expected, it did work just fine with multiple external HDs I tested. I then wanted to test it with a larger backup, so I copied 8 movies into the documents folder, duplicated that folder 7-8 times to about 300GB. I then formatted an external western digital drive (USB3.0), used a 3rd party (Aukey) USB-C to USB converter and set Time Machine loose. About an 1.5 hours later, TM had successfully backed up my clean OS (+ movies) MBP, 341GB worth. Now I'm left wondering what files inside by old MBP which I brought into the new machine initially through a TM restore, resulted in the crashing issue. Perhaps it's not a function of sheer data transfer (341GB is larger than my previous TM crashing experience), perhaps I have files larger than 4GB movies that are the issue (which jives with the crashes a video editor user talked about when moving files between drives). Next up will be to migration assistant to again bring my files across and see what happens....

People, the easiest way to confirm this issue is to try and copy the JPG image that Riza posted (DSC_0582.JPG) from your 2016 MBP to a USB-connected hard drive/flash drive. Your machine should freeze, automatically reboot, and log a Kernel Panic file.
 
I do not think it has anything to do with file size. As one of the posters above I also have one media file (a HD motion loop for a VJ application, about 600MB in size) that freezes the MacBook as soon as it is transferred over USB-C. Does not matter to what drive or through whatever port, it freezes it every time after the exact same amount of data transfer.

When I initially did a Time Machine backup I showed the same crashing behavior. However, I now suddenly do not have issues anymore. But I also no longer have the problematic file on my system.

I could be completely wrong but to me it looks as if as certain sequence of information triggers the crash. This is good news, sort of. Because that would mean that it is either a bug in the driver software or at least something that could be fixed with a software fix. And the exact bug should be fairly easy to locate.

Update: Time Machine is back crashing again, Acronis is crashing as well.
