Photoshop CS5

I am still in the progress of setting up my 2 x 27" iMac's ,my first purchase in 2010 27" late 2009 unit, this has come about due to my 2009 unit HD failure several years ago it has been a long journey and I see the light at the end of the tunnel as they say , about 8 months ago a late 2012 27" added, 2012 unit has install EL Capitan 10.11.6 and Lightroom 6, just curious will CS5 operate in 10.11.6, if not I know I can run it in my 2009 unit which has Mountain Lion.

Thank You Kindly for Your Time and any suggestions received,

Kind Regards......
