BLDC tool for MAC isn't recognizing VESC


I’m trying to change my ride setup to FOC, but my BLDC tool does not recognize my VESC.

I’ve all ready tried changing usb cables and ports but the outcome is the same.

I had previously managed to configure my ride settings and had no issue at all so I don’t think it is a compatibility issue between my VESC version and the BLDC tool version. I have never updated any of them. I think it might be related to software update on my laptop. I’m using MacBook pro with macOS Sierra 10.12.6

Any ideas on what could be wrong?

Thank you in advance for any help!

Are you connecting the cable then turning on the vesc then opening the bldc tool?

Then again, this might be a blessing in disguise if your trying to switch to FOC…

So many people have had problems with FOC and so many Vescs have died.

Not really familiar with MacOS I use Ubuntu though so familiar with whatever is common from UNIX/Posix compliance looks like they also have dmesg though for seeing new connected devices

when I hook up my VESC 4.10 HW and go to terminal and type dmesg (enter) I get something like below:

[937419.047632] usb 2-1.1: new full-speed USB device number 30 using ehci-pci

I just upgraded mine to the 3.33 firmware and using the new VESC tool has been working well as far as I can tell on a couple of small trips (new interface with wizards for motor and control config worked without a hitch too, took me a while to realize the write app was separate from write motor config for adding UART for metr support but otherwise good to upgrade too).

Hi! Yes, but still the bldc tool seems to not recognize the VESC.

The VESC seems to work fine, I haven’t had any issues while riding my board and the last time I updated my riding settings (one month ago) bldc tool was working fine, that’s why I think is more of a driver issue or something like that since MacOS last upgrade :frowning2:

Did you upgrade from Sierra to High Sierra ?

I had that same problem but not on Mac,are your vesc’s flashing ie do they have power when you turn your power suply on? Mine was a driver issue,i just installed a new one and was good to go.


Yes, vesc’s are flashing when they have power.

Yes, the upgrade was from Sierra to High Sierra. Have all ready re-installed BLDC tool but the problem still persist, the VESC does not appear when connected.

I’m not sure what happened. I have not upgraded from Sierra. Try connecting something else to the USB port and see if it works.

Where did you get the vesc tool for Mac ?

I am running into this problem as well. Anyone figure this out? Got a 2017 MacBook Pro without touchbar running Mojave 10.14.3 The 2 USB-C model. I got a Satechi USB hub
