I am having the same problem. I am also unable to restore or update my iPhone or iPad. I am not sure if this is a related issue, but I would still like to know what that framework does and why it is not working.
I have no idea why but the telephony thingie is working now. On both my iMac and MBP that extension hung up a the first boot up and several after. Then for what ever reason both are now working. I still do not know what it does... Google has links to Android phone usage. I am in the dark.😕
Having the same issue here. This creepy telephonyutilities.framework appears on the dock every time after I boot my macbook, and then became unresponsive. Need to force quit it every time.
