Perhaps anyone can help me solving a problem :
I use X-rite I1 profiler, version 1.7.1 to calibrate the screen of my macbook pro ( late 2013 retina). Since some time I1 profiler crashes at the first attempt to start it, at the second attempt after the crash it starts as usual. I tried removing the software and all configuration files located at library, and reinstalled profiler, but it doesn't help. The problem only occurs when the I1 Display pro device is connected by USB, without the device connected, profiler starts right from the beginning.
The I1 display pro is reported properly each time I insert the plug into the macbook. After a safe-boot and reboot, profiler starts one time exactly as it should, but during the calibration process it lost the connection to the device and profiler hang. After reboot, the behavior again was the same as described above.
The current OS is 10.12.6, but the same issue appeared suddenly with 10.12.5, although it was running ok for the first time.
Does anyone have an idea how to solve this issue ?
