[Chimera-users] Command line doesn't work properly on Mac

Hello All, The command line in Chimera seems not working properly on my Mac. Any input in the command line will not show unless you select them. Does anybody experience this problem? Or any idea about this? Both versions of 1.11 and 1.11.1 have been tried. My mac is iMac (Retina 5K, 27-inch) OS X EI Capitan. Thanks, Leon
