Hi, I would like to run my ST2000XCM on a MacBook. MacBook Pro, Retina 13 inch, Anfang 2015 OS X El Capitan 10.11.5. First I updated the ST2000XCM via driver checker on a Windows 7 / 64bit machine. On the Mac I successfully installed SBIG Drivers for OS X, ftp://ftp.sbig.com/pub/CCDOpsLiteUniv.dmg and CCDOpsLite for OS X , ftp://ftp.sbig.com/pub/CCDOpsLiteUniv.dmg .I powered on and plugged in the Camera, the fan did not come on and CCDOpsLite did not found the camera. Back to the windows 7 notebook all works fine. Do you have some advice, please? Kind regards Konrad
