Hi, without any apparent good reason, the keyboard starts to work not properly. If I push "m" or left comand, the application is reduce to the dock.
I also tried changing the keybord settings but unfortunately nothing good happened. Any suggestion?
Thanks in advance

If your Wi-Fi is capable of generating a 5 GHz signal, try that.
Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time.
