Question: The MacOS High Sierra

Sirs, good afternoon.

The MacOS High Sierra operating system, 10.13 and update 10.13.3, when installed corrupt the system of reading the wifi networks.



That is, the computer iMac or Pro, does not visualize any active wifi network the only connection to the internet is cable. I confess that a MacBook without wifi does not make sense.



WHEN THIS PROBLEM WILL BE CORRECTED ???



Tks

Answer:
Answer:

None of my Mac suffered from any such problem after being upgrade. I suggest that your problem will be fix when you fix your network connection for your Mac. Apple has nothing to do with that problem.


A possibility is that some of the parameters for your network configuration were change during the upgrade. I have had such a problem in the past. Review your network configuration for any such changes.

All network parameters were made, redone and redone again. At home I have 03 Macs the 02 with SIERRA 10.13, does not recognize the networks neither mine nor the more than 100 that has in the building. The computer with the old system already recognizes all of them.



This is a problem with this version of SIERRA.

What does Wireless Diagnostics show?

Also try turning off Bluetooth.


If your Wi-Fi source is capable of generating a 5 GHz Wi-Fi network, try that to help avoid conflicts with Bluetooth.

I'd like to make a suggestion here.


As much as the upgrade through the App Store is a great idea, if there are any issues surrounding wifi during update then the OS can throw up some strange issues.


My advice is to create an installer on a USB drive and do a clean install from that. Its always best to make sure your system is backed up before doing that. There is a great App called Install Disk Creator which makes those bootable USB drives. In this case if you create an installer you can do it from that. Here is a link to the instructions and download links to create that bootable usb drive.
