Can you please fix this issue apple developers? Sonarworks is not working due to this problem. I don't think new OS is necessary if it is going to kill/terminate what were preserved before. I am not sure what is your purpose of changing OS if majority of people are using your products for other major reasons than Facetime and etc :/ Mac is only getting faster due to increase amount of CPUs and GPUs. I don't think that OS makes a major difference. Make the fix ASAP. I don't even like putting up complaint comments or letters. I even changed my new macbook two times due to some trouble shootings of your faults. I know you work hard and do fast response to complaints but your coding or some sort of OS developers have to be much more considerate next time.
