homebrew vs flashing

This is a heads up for all OSX ppl who uses homebrew to tap proxmark3.

I realized today that the flasher gets installed as proxmark3-flasher.

bin.install "client/flasher" => "proxmark3-flasher

All documentation usually states  "client/flasher comX ..."

Below is a suggestion on how to use the proxmark flasher and client correctly on your OSX

-- enter the right folder.  This example indicates v3.0.1 is installed.
$ cd /usr/local/Cellar/proxmark3/3.0.1

--finding your device-port
$ ls /dev/cu*

-- flash bootrom
$ ./bin/proxmark3-flasher /dev/cu.usbmodem1411 -b ./share/firmware/bootrom.elf

-- flash fullimage
$ ./bin/proxmark3-flasher /dev/cu.usbmodem1411 ./share/firmware/fullimage.elf

-- swap into the bin-folder,  to have right paths for scripts and hardnested files when running.
$ cd bin
$ ./proxmark3 /dev/cu.usbmodem1411

Re: homebrew vs flashing

Thanks Iceman for this.

I couldn't update my Flashers, and with this tips I still can't.

The problem is as followed

$ cd /usr/local/Cellar/proxmark3/3.0.1
$ ls /dev/cu*
/dev/cu.Bluetooth-Incoming-Port	/dev/cu.usbmodem1431

$ ./bin/proxmark3-flasher /dev/cu.usbmodem1431 -b ./share/firmware/bootrom.elf

Waiting for Proxmark to reappear on /dev/cu.usbmodem1431................ 

And he is waiting till infinity... Also the lights on my Proxmark turn Red and Orange near each other after this...
When I press the button on my Proxmark (Or pull out the cable) it states

Waiting for Proxmark to reappear on /dev/cu.usbmodem1431............................................................... Found.
Note: Your bootloader does not understand the new START_FLASH command
      It is recommended that you update your bootloader

Writing segments for file: ./share/firmware/bootrom.elf

And it stops here...

How can I update this when I want to update but it gives the error that I have to update?
I also tried by downloading manualy, and followed this but got the same problem anytime.

I'm running on macOS Sierra 10.12.6
