Verse Of The Day:
But, “Let the one who boasts boast in the Lord.” For it is not the one who commends himself who is approved, but the one whom the Lord commends. — 2 Corinthians 10:17-18 (NIV)

PostHeaderIcon USB-to-Serial adapter for Mac

I have an older IO Gear USB-to-Serial adapter that I have used for a long time.   When I purchased it I was only using Windows laptops and never had a problem getting drivers and getting it to work.  When I switched to a MacBook Pro a couple of years ago, I was able to get it working by downloading the Mac drivers.  However, after upgrading to El Capitan I wasn’t able to get the adapter to work.  I did some searching and came across the site listed below.  The command that is described in the post didn’t work, but the comment by James Morris did get the adapter working.

  1. So reboot the Mac into recovery mode.  Press Command+r durring reboot.
  2. Click Utilities, Terminal
  3. Type: csrutil status
    It will probably come back and say it is “enabled”.
  4. Type:  csrutil disable
  5. Reboot

You should now be able to open terminal and type ls /dev and see the device.  My adapter shows up as tty.UC-232AC.

Hope this helps someone else.

Eric
