The brand new MacOS Sierra has been a disappointment for me so far. No, not because Siri on Mac utter nonsense (I already knew that from the iPad ;) ), but because it caused me a bunch of problems on my 2015 Macbook. So Sierra deleted during installation unasked two laboriously set up VPN accesses that I urgently need for work. Less dramatic, but at least as annoying: Since macOS Sierra, my Macbook has had massive WiFi problems. Sometimes it doesn't connect to the Fritzbox at all, then the connection breaks off again. And even if the WiFi is working, the WiFi icon in the menu bar doesn't stop blinking. Mega nerve ;) Luckily there is a solution for the WiFi problems of macOS Sierra.
The solution is to reset your Mac's WiFi settings. By the way, you won't lose your previously saved network accesses (at least that's how it was for me). In any case, the steps described have led to stable WLAN access again on my Mac.
This is how you do it:
1. Open Finder and navigate to the folder
Open the Finder and use the keyboard shortcut Shift + CMD + G. In the input window that appears, enter the following folder name to call it up:
2. Backup and remove WiFi settings
In the folder that is now displayed, you must delete the following files. To be on the safe side, copy them to another folder or folder first. moves them. Here's how you can restore the settings if they don't fix your Wi-Fi problems under macOS Sierra:
- apple. airport. preferences. plist
- NetworkInterfaces. plist
- preferences. plist
3. Restart Mac and hope for the best
Now restart your Mac and reconnect to the WLAN of your choice. Ideally, the WLAN errors should now be a thing of the past. If, contrary to expectations, it does not have the desired effect, you can of course restore the files you just deleted.
How do you feel about macOS Sierra? I don't really like the new features so far, but that could also be because I can't use most of the standard Apple applications (e.g. Safari and Email) not or only rarely use. Siri couldn't help me with my test questions either (especially since the web search via Bing is a cheek anyway ;) ) and otherwise I just had the problems described. Well, maybe it will be. In any case, none of this is running as smoothly as the excellent El Capitan.
By the way: The steps described not only work in Sierra, but also in older versions of macOS!
