Arduino IDE serial ports not working on EL Capitan OSX

[HBRancher]

Anyone know how to fix Arduino IDE serial port lockup on EL Capitan OSX ?? Thanks

[matthijskooijman]

You are the first to report this issue, so could you please provide more details? What happens exactly? What did you expect? Any error messages / verbose output you could add?

Hi Matthijs Kooijman,

I have the very same problem.

Arduino IDE does no longer show "tty" ports in port list, but just "cu", even if device "/dev/tty.usbmodem1A21" looks to be correctly created when USB cable is connected. Second, when I try to transfer any sketch, after compilation and link, when it tries to transfer datas to my genuine Arduino UNO, process gets stuck completely and no return error is reported. My bluetooth mouse also get stuck, while, fortunately, touch pad still works, so I can close Arduino IDE. My Mac fan, that usually can be barely heard, starts to slowly to increase its speed till maximum.

If I run again Arduino IDE in this situation, it reports no USB port at all, even if I disconnect and reconnect my Arduino UNO.

The only way to stop these effects is to turn off and back on my Mac.

I hope I gave you enough elements to start to catch this issue, that has completely stacked my project.

I look forward you hearing from you.

Best Regards.

Hi Martino,

Unfortunately I had no success: “nam install tmpvar/node-serialport#el-capitan” returns a long list of errors (see below), so I still can’t fix that issue.

Please also find attached a copy of the file “npm-debug.log”.

I look forward to hearing from you.

Best Regards.

Sorry Luca, my message was intended as a reminder for myself, not a real way to solve the issue. We'll tackle this very soon I promise :smile:

[wizardofwords]

Hi Martino, Thanks so much for your time, I really appreciate that. I would greatly apreciate also if you could recommend even a temporary solution to that issue. Thanking you in advance, I look forward to hearing from you. Kind Regards.

Unfortunately, he only fix that I have found, so far, is the return to Yosemite.... I've reported the problem to Apple... Under El Capitan, any use of the USB ports would lockup my Bluetooth keyboard and mouse. So, either the drivers from the Arduino must be re-written.... or... there is actually a bug in El Capitan.... Good Luck to all.... I'm also still waiting for any solutions...

[tmpvar]

Heads up, the pull request @facchinm mentioned has been landed and is included in serialport@2.0.1

npm install serialport@latest should bring in these changes if you (@wizardofwords) wanted to try again!

[michaelemery]

This issue is not a bug, but rather the result of Apple's new System Integrity Protection (SIP) policy called "Rootless". Rootless was introduced with the launch of El Capitan. The effect of Rootless is that many applications and drivers (such as those required for your USB serial connections) will no longer operate correctly. Third party vendors must modify their drivers and applications in order to comply with the new policy.

There are "fixes" floating around the internet that require you to manually disable certain El Capitan security protection features – it is not recommended that you implement these fixes as they are either dangerous, or opportunistic security scams. The only thing you can really do is wait for third party vendors to rewrite their software.

Unfortunately, this is not the answer anyone wanted to hear.

[Dark-Archer]

You say that 'Third Party Vendors' need to re-write their software, Does this mean that genuine Arduino boards will still work?

[ffissore]

Fixed by #4006. Available with latest hourly build http://www.arduino.cc/en/Main/Software#hourly

[cmaglie]

For the record: we tried the fix on our macs with various Arduino/Genuino boards and it is working flawlessly. If you are still experiencing problems maybe your boards uses proprietary USB-Serial chips that are not compliant with CDC-ACM?

[michaelemery]

@cmaglie - are you using El Capitan? I had no problems with Yosemite on either of my macs (including my MacBook 2015 with USB C). However, since installing El Capitan on both my macs, the USB serial ports will only communicate using Windows 10 as a Bootcamp OS. Earlier versions of Windows would be fine too, but they have to be run natively (not as a virtual OS within El Capitan). If you are using El Capitan, then you must be using newer drivers.

[cmaglie]

are you using El Capitan?

yes, the issue is all about "El Capitan".

I had no problems with Yosemite on either of my macs (including my MacBook 2015 with USB C). However, since installing El Capitan on both my macs, the USB serial ports will only communicate using Windows 10

Which boards are you using? In particular, I want to know if the USB-2-Serial chip is an atmega16u2 with Arduino's firmware or is another proprietary chip like FTDI or CH340.

[wizardofwords]

Hi Federico,

I download latest nightly release but it does not fix my Mac problem with USB ports.

Regards.

[PaulStoffregen]

Are you certain you're using a genuine Arduino board? Not one of those Chinese clones with a CH340 chip?

[wizardofwords]

Hi Paul,

I only use 100% genuine Arduinos.

In my opinion, if this issue would be caused by a not 100% compatible USB chip, my Mac should simply not recognize and ignore it or transfer would return an error message.

On the contrary, when Arduino IDE tries to upload my sketch, it crashes and also makes my bluetooth mouse crash as well: only way to close it is kill it from shell or from “Cmd+Alt+Esc” (luckily touch pad keeps working). Afterward, my Mac fan starts slowly to increase its speed till maximum. At that point, I can only shut my Mac down (it takes ages to turn off, ten times longer than usual).

Best Regards.

Luca

Hi All,

Today I have bought a Yún (original, obviously!) and I have tried to upload a sketch: it does not work anyway, but IDE has not crashed and it has not crashed my bluetooth mouse.

Also it has displayed the following error message:

Hi Paul,

I only use 100% genuine Arduinos.

In my opinion, if this issue would be caused by a not 100% compatible USB chip, my Mac should simply not recognize and ignore it or transfer would return an error message.

On the contrary, when Arduino IDE tries to upload my sketch, it crashes and also makes my bluetooth mouse crash as well: only way to close it is kill it from shell or from “Cmd+Alt+Esc” (luckily touch pad keeps working). Afterward, my Mac fan starts slowly to increase its speed till maximum. At that point, I can only shut my Mac down (it takes ages to turn off, ten times longer than usual).

Best Regards.

Are you sure /dev/cu.usbmodem1A21 is the right port to use? A friend of mine was using an Arduino Uno with his OSX laptop yesterday, and had to use /dev/tty.something IIRC. Don't take my word for it though, I'm not a Mac user at all :-)

[wizardofwords]

Hi Matthijs, Honestly I would expect it was "/dev/tty.usbmodem1A21", but only "cu" ports are listed in Arduino IDE... Regars. Luca

That suggests to me that no serial port for the Arduino is available at all, and this cu port is just your normal serial port, or an internal one, or whatever. Does the cu port disappear when you unplug the Arduino?

[wizardofwords]

Hi Matthijs, When I connect Arduino to my Mac two devices are created: /dev/cu.usbmodem1A21 and /dev/tty.usbmodem1A21 but just "cu" one is listed in Arduino IDE. When I remove Arduino, also both devices are removed. Regards.

Right. I suspect the tty one is the correct one, but I'm not entirely sure. I do think something was fixed in the serial port listing recently. Are you using a recent hourly build, or a release build?

[PaulStoffregen]

Normally the "cu" device is the proper one to use.

The "tty" device has additional support for the "RI" (Ring Indicator) handshake signal, present on old serial interface dialup modems. If you open the device in blocking mode, the tty version will block until the phone rings. This is a traditional (or "ancient") BSD Unix behavior, to create 2 devices for modems... one intended to dialing ("cu") and the other intended for answering ("tty").

The JSSC library (and also the older RXTX library) used by Arduino opens the device in non-blocking mode to work around this, so with the Arduino IDE there's no difference. Old versions of Arduino show both. Quite some time ago, code was added to only show the "cu" devices in the Tools > Port menu. The fact you're not seeing the "tty" version is intentional, not a bug.

[matthijskooijman]

@PaulStoffregen, thanks for clarifying, I learned something again :-)

So the real error is:

avrdude: ser_open(): can't open device "/dev/cu.usbmodem1A21": No such file or directory

Somehow the device file does not exist (anymore) when avrdude wants to open it?

[wizardofwords]

Hi Matthijs, Yes, I use last nightly release and also serial port last release. Regards. Luca

Well, this is a mysterious problem. I can tell you that doesn't happen on my Mac with El Capitan.

Hi Paul,

I definitively agree with you: it is a weird issue.

I am ready to let you have a look via TeamViewer: maybe you can see something macroscopic that I can’t.

Kind Regards.

So I have this same problem with my Arduino Due, and I've been doing a lot of testing to narrow it down. It only happens on El Capitan.

When I plug in the Due to a El Capitan Mac, I see this error in the Console system logs:

11/16/15 9:37:19.000 PM kernel[0]: 049249.868982 IOUSBHostHIDDevice@14100000,2: IOUSBHostHIDDevice::interruptRetry: resetting device due to IO failures

It repeats the error about every 5 seconds.

Could this be some kind of driver problem? An unsigned ktext disabled by SIP? Or a problem with the Atmel USB system? Should we submit a bug report to Apple?

I've made a test app to test the most basic failure case using JSSC: https://github.com/odbol/JSSCTest.git

Tested by making a runnable JAR from that project, and running it:

$ java -jar /Users/umac/Downloads/Arduino-JSSC-Test2-delay.jar

@cmaglie could you perhaps explain how you fixed this? It's not even working with the very basic JSSC test app I posted in the previous comment, and I'm having trouble understanding how your commit #4006 fixed it. Any advice would be much appreciated! Thanks!

basically the IDE now ignores the case when detecting serial port VIP/PID. This solve the issue about "disappearing" com port in ports list, but there should be more since some users, like you, are experiencing upload failures on OSX El Capitan.

11/16/15 9:37:19.000 PM kernel[0]: 049249.868982 IOUSBHostHIDDevice@14100000,2: IOUSBHostHIDDevice::interruptRetry: resetting device due to IO failures

Unfortunately this log doesn't tell me much, but it may be an hint to understand what the real cause is.

I've got a pro micro with atmega 32u4. This used to work flawless, but now (even with latest build) i can't upload, use serial port etc... Same as described in this topic. But it is even that bad that my mac completely stops working properly after trying to upload. Kernel_task process uses more than 100% cpu. Can't shutdown or reboot anymore.

Even a clean install of osx (el capitan) and arduino don't give me any progress. Anny help would be appreciated.

So I found a fix for my app, which was actually pretty simple (after days of debugging). I just lengthened the delay between after scanning for USB devices (getPortNames() function in JSSC), and before trying to openPort(). Seemed to fix the problem:

        String[] portNames = SerialPortList.getPortNames();

         System.out.println("Found " + portNames.length + " available ports.");

         for(int i = 0; i < portNames.length; i++){
             System.out.println(portNames[i]);

             result = portNames[i];
         }

        // wait a bit since otherwise you get a "port open" exception if trying to open directly after calling this.

        // this is the magic part: increased from 100 to 900ms
        try { Thread.sleep(900); } catch (InterruptedException ie) {}
// this is the old one that gave a "port not found" exception
//      try { Thread.sleep(100); } catch (InterruptedException ie) {}

@odbol you should report your findings to jssc author https://github.com/scream3r/java-simple-serial-connector

Why is this closed? It is NOT fixed.

Third party vendors must modify their drivers and applications in order to comply with the new policy.

OK, third-party.. Is this a case of "Wont Fix"?

[matthijskooijman]

@mralexgray, I suspect that there might be multiple issues with serial ports on El Capitan. One of them, related to serial device enumeration was fixed, but I'm not sure if all of the comments in this issue are about them. If you still have a problem with the latest hourly build, consider opening a new issue (after searching the tracker for open issues matching your problem, if you didn't already).

FWIW, we've been seeing problems with Teensy when using USB Serial at high data rates with El Capitan. Here's the conversation.

https://forum.pjrc.com/threads/31043-Teensyduino-1-26-Beta-1-Available?p=89113&viewfull=1#post89113

A couple weeks ago I put some serious effort into investigating the issue with a USB protocol analyzer. I'm afraid the news is not good (at least for El Capitan). All the data was being properly sent, with nothing unusual on the USB cable corresponding to the occasional data loss seen my programs running on El Capitan. I tried adding code to occasionally send a ZLP within long sequences of full size packets as a possible workaround, but unfortunately that made no difference.

This rapid data flow problem may be completely unrelated to all the problems above.

I had the same problem with FTDIs, in the end I installed a correct driver and uploaded the program, but after using the FTDI for a few days in the USB port, the port don`t work anymore until I restart the Macbook. So, if I use any of the USB ports on Mac it stops working. Are there someone with that problem?

[Breidenbach]

This is a persistent problem with El Capitan and the Arduino IDE. Since upgrading, I have yet to successfully connect to my genuine Arduino Uno when using El Capitan even after trying about a half dozen "solutions" presented on the internet. Fortunately I run Windows XP with VMware Fusion under El Capitan, and the IDE does connect in that environment! But then, not everyone has that option.

If one of the developers would like me to try something, I would be more than willing to collect data and run tests.

[lrothschild]

After upgrading to El Capitan on my 2014 MacBook Pro, my "Genuino" made-in-Italy Arduino Uno has acted erratic and finally stopped uploading. The IDE has been unable to find any port except cu.Bluetooth-Incoming-Port, which of course does not work for uploading. I've scoured the Arduino forums, but have not found any workable solution. All suggestions welcome!

[DrewOJensen]

I second Irothschild issues. I've got an ArduinoISP that is recognized by OS X system information, but in the IDE, I only get the Bluetooth-Incoming-Port. I also am on El Capitan. Using latest build.

[Breidenbach]

Same problem, bluetooth gets lost, no connection to arduino using PR-4490-BUILD-495 (1.6.8) This file is Apple complaining about wake-ups, but might be helpful otherwise. After updating to latest El Capitan version - 10.11.13 - took a screen shot of the console. If there is a better way to get info to help find the problem, tell me what to do.

[squidlyboy]

Mac OS X EL Capitan 10.11.3 - Arduino 1.6.7 This is still broken. Completely locks up my Mac when its uploading any sketch to the board via USB serial

[32u4]

@squidlyboy : Did you try using a usb hub? I had exactly the same problem as you have and i accidentally discovered that all my boards (pro mini, pro micro, nano, mini) work as long as i use a usb hub. Without a hub my mac locks up... can't even shutdown properly.

[Breidenbach]

When I use a hub, I get: avrdude: ser_open(): can't open device "/dev/cu.usbmodem1A21": No such file or directory ioctl(“TIOCMGET"): Inappropriate ioctl for device

When I don’t use a hub, I lose my Bluetooth mouse and keyboard, and the sketch is not uploaded. Sometimes it resets the Arduino, but still doesn’t upload. This is after moving the app to the root directory, then copying it to Applications.

BTW: @Richard Loxley Are you familiar with Apple’s new “sandbox” security? It’s not just a matter of permissions anymore. http://www.macworld.com/article/2948140/os-x/private-i-el-capitans-system-integrity-protection-will-shift-utilities-functions.html

And I have tried to disable this feature, but it didn’t help.

@Breidenbach which board are you using in https://github.com/arduino/Arduino/issues/3928#issuecomment-175933160?

Also, are you using a powered or unpowered USB hub?

The Symantec Vulnerability Protection has found and blocked an attack (23387). entry in the console seems suspicious, does it occur every time you trying to upload a sketch?

I've just downloaded the nightly build dated April 08 2016 on OS X El Capitan 10.11.3 I still face the same issue, I can't upload a sketch to the board. Arduino IDE see the board connected to /dev/cu.usbmodem1421 but no luck uploading a sketch to the board.
