Compressor fail
Hi. First I want to apologize for my English.
To me, the same thing that is happening to you. When I start the computer, I see two processes: compressord and compressorHelper, and sometimes a third that I do not remember what it's called. It happens to me in my two machines: MBP15 2017 with Readon pro 555 and an iMac 21.5 2015 retina. Both with the latest version of macOSX Hight Sierra.
I have tried everything they have said and nothing worked for me. At the moment all I can do is turn on Compressor and turn it off again.
Annoying, I hope Apple fix this soon.
