Since update to Highsierra lot of problems

[marijkell]

Hi, since I updated to Os Highsierra 10.13.4 I have a lot of problems. My emailaccounts do not work anymore. I have to start the computer twice each time, otherwise my mouse does not work. The sound often does not work. I have tried everything, nothing seems to work. Can someone help me ? Thanks in advance !!

Create a time machine backup and reinstall MacOS after erasing your drive. Then selectively copy your files back from time machine but don't restore complete drive. It seems something went wrong during update and your mac is not recognizing kexts properly.
