I have directly updated to Sierra . Used this guide after installation but there is some problems. Help me pls.
1. Brightness and sound volume hotkeys doesn't work (and after every reboot i need to change settings manually)
2. In system prefs>touchpad there is no options to change , just grey window (Elan touchpad)
3. When i opening video (trailers) on IMDB in safari or other browser my laptop just stuck , can't do anything until turn off it every time.
4. File transferring to usb noticeable slower then on capitan, may be usb3 crashed after update.
5. other little bugs like restarting when I'm plugging in usb (not every time)
6. and finally its just my caprice if you can answer , tell me pls how can i turn on 3fingers tap to quick look up links in safari. (its the same that lookup words via dictionary)
