What kind of Barcode Reader USB can work on El Capitan / iMac I don't know anything about Apple world... Our customer did have a Macbook (I think) and now he did switch to an iMac (I think with El Capitan?).

A simple barcode reader USB did work on old Mac. It did "beep" and it did write the scanned number properly on the screen.

With new iMac now the barcode reader does "beep" but it doesn't write anymore on the screen (on an Excel / Notepad / Browser etc etc etc).

Reading on the internet seems a well known bug of El Capitan.

Someone has tested some USB barcode reader and it works on El Capitan? For now not a big problem the cost... Or do you have a workaround?

Thank you
A USB bar code reader should just work out of the box.

I am personally using a Symbol (aka Motorola, aka Zebra) bar code reader.  Upon plugging it into my iMac running OS X El Capitan (10.11.6), it just shows up; no drivers were needed for the install.





This is the exact model bar code reader I am using for this example:  Symbol USB Bar Code Scanner PN# LS2208




I have been using this (and another Symbol scanner, but I no longer have it) since I got this iMac with Mavericks (10.9.x) and I never need to install drivers for either of the scanners.

Doing a scan of a simple UPC bar code sends the characters to whatever application I am using (in this case, Notes)
