5 macOS Sierra problèmes et comment les resoudre

It can not be denied: macOS Sierra is much better than its previous versions. For most of us this has worked seamlessly and I personally think it’s the best macOS by Apple so far.

Although users have also reported many problems, while upgrading to macOS Sierra. In today’s post, I will talk about some of these issues and their fixes. I hope that will help you a lot.

# 1. Wi-Fi Problems


At this age of the Internet, slow Internet or connection problems are the most frustrating problems that anyone could experience. After installing new macOS Sierra some users reported that websites, including downloads, load very slowly.

The fix

First, make sure your router is working properly and that there is no connection problem with your ISP. Once you are sure there are no problems as mentioned above, try following the steps below, as shown below.

Open  » Finder « , select GO from the menu and press Alt to display the Library option

In Library, go to / Preferences / SystemConfiguration /.

Now delete the following files

  • preferences.plist
  • com.apple.airport.preferences.plist
  • com.apple.network.identification.plist
  • com.apple.wifi.message-tracer.plist
  • NetworkInterfaces.plist

Restart your Mac and your router. You are Wi-fi should work properly now.

 # 2. macOS Sierra Installation Freezes or crashes


Well, it was the most discussed issue by users when installing macOS Sierra. Many users have complained about freezing or installing their Mac when upgrading Sierra.

The fix

Here are some methods you can use to get rid of this annoying problem.

Method 1: Disable or uninstall your antivirus software by interrupting it when installing Sierra.

Method 2: Check your Internet connection and make sure it is working properly

Method 3: If everything looks good and the problem persists, try installing macOS Sierra in safe mode. To do this, turn off your Mac by holding down the power button. Then, turn it on and press Shift when you hear the startup sound. When you see the Apple logo, release the Shift key and you should now see the safe mode screen on your Mac. Continue the installation process.

# 3. Not enough space to install


Annoying and can make you repeat the installation process again. If you do not have enough space to install the new operating system.

The fix

Make sure you have at least 8 GB of free space before you install. If this is not the case, delete some unnecessary and useless files and applications. Or transfer some files to an external drive.

# 4. iCloud error and authentication problems


Some features of macOS Sierra only work with iCloud and during the installation process it prompts you to enable these applications such as Storage Optimization and iCloud Documents & Desktop. If you skip this step, an annoying problem starts to appear from time to time – Authentication problem or iCloud error

The fix

If you see an error such as « iCloud login error », disconnect from the iCloud, restart the Mac and try to reconnect to the iCloud account.

# 5. Installed applications display a ‘corrupt and can not be opened’ error


After installing macOS Sierra, this problem may begin to appear. When you try to launch an application, you may get an error message like « damaged and can not be opened »

The fix

Make sure you have the latest version of the application you want to launch, otherwise update the application. If the problem persists, completely remove this application and reinstall it.

If nothing else works, you must clear the cache. To do this Open Finder

Click « Go » in the top menu and select « Go to Folder »

Then type « ~ / Library / Caches  » in the text box.

Now, delete the files from each folder and repeat the process for / Library / Caches (without the ~ symbol)

As a last resort, you can also try running the application by holding Cmd + Option Keys.

Although we have found macOS Sierra exceptionally good, here are some of the issues reported by members of the Remo Software community. Hopefully, we are able to erase at least some of them.
