So unfortunately I found out after I bought my Arduino Starter Kit that the Arduino Uno does not play nicely with a certain combination of Macbook Pro/El Capitan [Arduino IDE is unable to detect USB port/connection with the board]. I've tried a bunch of solutions, including:
Downloading USB drivers
csrutils enable --without kext
Installing virtualbox and running the arduino IDE in Windows 7 (still not detected)
And possibly some other longshot fixes that I've seen in the various threads on this topic. While some of these different fixes have been successful for various people, there does not seem to be a one fix fits all for this problem.
Which leads me to the issue I'm having, because even after doing just the first project in the book I am HOOKED! I really can't wait to get my hands on a board that will work with my computer, some parts, and a book to start making some cool projects.
Does anyone know of an arduino board that will 100% work with a Early 2015 Retina Macbook Pro running El Capitan? Or is it possible that the problem with the computer hardware/El Capitan will be there regardless of the Arduino board?
Thanks for any help!
Edit: When I get home tonight I'm going to try a different USB cable/use a USB hub intermediary in the hopes that might fix the issue like the other guy that's on the front page. Hard to imagine there'd be an issue with the USB cable provided with the official starter kit but I have seen a few people say it fixed their issue so it's worth a shot.
I would be interested to hear about how the USB hub idea works out.
I have an older Mac and running Yosemite, not anxious to upgrade to El Capitan. When new computer hardware and OS's come out, it seems there is a period of time when accessories need to catch up, and I fear Arduino is one of those things. I remember when Yosemite came out a lot of people had severe troubles. I think my next Mac is going to be a used one, just a year or two old.
PC's have the same trouble, the forum was filled with people having trouble the day Windows 10 came out.
You may consider getting an older computer to use for Arduino activities. I have a 10 year old Dell computer that I put Linux on, and it works great for Arduino.
Or, you could get a bluetooth adapter and not use USB at all, except perhaps for power. For power you can use a typical modern cell phone or tablet charger block and plug the USB cable into it.
Something like EZ-link bluetooth or if you want to go super cheap, an HC-05 module like this.
Holy moly, when is it time to think maybe there's a problem with the arduino board itself?
Different USB cable didn't work
Connecting via a USB hub didn't work
Breaking out a much older laptop running Windows 7 didn't work (STILL not detected via USB ?!?!)
Different USB cable on older laptop didn't work
Yeesh! What a monumental pain in the ass!
Do I risk getting another starter kit that has a Uno (with the hopes that it was a defective board)?
Or do I try and find an arduino board that isn't plagued with endless USB problems (is there such a thing???)?
For the test with older laptop - did you install the Arduino IDE to get the drivers installed?
Also, is it a real one or a clone? Check the chip next to the USB connector - official board has an Atmel 16u2, the clones usually have a CH340G or other generic USB-serial adapter; the clones require a driver for whatever USB chip they have (but otherwise work fine - I hardly ever use "real" arduinii)
Yes the older laptop has the IDE. When the arduino is plugged in via USB nothing pops up like 'installing device drivers' or anything that seems like the device is being recognized. Nothing showing up in Device Manager under Ports etc.
It is a real Arduino Uno from the Starter Kit on amazon - yes it has the little Atmel 16u2 chip. It almost seems like having a clone with the CH340G would be an easier fix! I'd LOVE if I could just purchase an $8 driver from the mac-serial-usb website or whatever it is just to end the pain of trying to get the arduino working. I just want to build some cool stuff gosh darn it!
I suggest contact the seller and explain you tried it with 2 computers. They may send a replacement. If they don't want the bad one back, keep it because you may be able to repair it when you get a bit of experience. It could need the 16u2 programmed or something like that.
I have same problem.
I have tested several boards (including UNO and Mega) and they don't work with El Capitan iOS 10.11.
Note I have tried the same boards using same USB lead on a different computer running iOS 10.10 and they work fine.
Note the only boards I can get working on El Capitan are the teensy 2.0 and 3.1 ( I gather that Teensy uses HID, not serial, for uploading.)
If anyone has a solution I would love to know what to do.
I am using iOS10.11.3 (latest) on MacBook Pro (Retina, 13-inch, Mid 2014) with latest Arduino IDE
