My 15” Macbook Pro has been sitting on the black “Installing Software Update” screen at roughly 5% progress for 20+ minutes. :/ Guess I’ll be figuring how to safely solve this instead of working…
sorry to hear of anyone having problems with the update. for me, this update was quick and easy. no problems after updating. i am also very thankful that i am running macOS and that apple is being quick (lately) to patch problems.
