UR22 driver for El Capitan 10.11, can not find

Hi everybody,
I am trying to get a Macbook Pro mid-2012 to work with my UR22 but the oldest driver I find on the Support site is for 10.12.

I checked the FTP for older but UR22 is not listed in there.

Yet, I see people mentioning using UR22 with El Capitan.
Do you know where I can get a driver for OS X 10.11 El Capitan?

Thank you for any help!

Update: I am upgrading to 10.12 Sierra, hopefully UR22 will be happy with that.
