Hi, I updated my Macbook pro 2012 15" to OS Catalina and I cannot use Wi-Fi. Wierdly, wifi diagnostics doesn't get opened either. Has anyone else been facing a similar issue or know of an existing solution.
"Changing what Opens at startup" suggests that you may get relief by starting in Safe Mode (hold shift at startup).
Safe mode loads a little bit of software, then does a five minute disk repair, then selectively loads the minimal set of Apple-only extensions, Not including graphics acceleration, so screen updates will be wonky and slow, but ultimately accurate. Your Userid and password is required, even if you normally auto-login.
Safe Mode takes defaults for everything it can, but changes you make in Safe Mode will "stick" in regular mode.
"Works in Safe Mode; fails in regular mode" implicates something you added.
What’s your MAC address coming up as?
I did the reset, doesn't seem to help either.
same issue with Macbook
I have the same issue, any luck with this?
Its a macbook pro mid 2012 15" with 2.7Ghz i7
I did it until hitting minus. I tried adding it and it doesn't provide Wi-Fi as an option.
Yes I know......But I cannot find it :(
never mind i see you are still running mojave. I should never have upgraded
I have a similar issue, I think. What nobody else mentioned is that the WiFi icon in the top menu bar is infinitely looking for a network. Often together with a spinning beach ball cursor.
Yesterday, before the small update, but after installing Catalina, there were no issues.
The issue is at work, where I even have rebooted the wifi network. But others on other operating systems have no problems. Also my iPhone has no problem connecting to the network. My MacBook Air (2015) is the only machine with Catalina.
A personal hotspot on my iPhone is my workaround, works flawlessly...
System Information says:
And a long list with Local Wi-Fi Networks follows.
You seem to have Hardware showing, so this may not be the same problem as others. You should probably start a new discussion.
You may just have to re-specify what Network to join.
There is also an excellent but little-used feature that lets you repeat a basket of Network settings in one menu-choice:
How to use network locations on your Mac - Apple Support
For no Hardware, suggestions include deleting and re-adding the interface as described above, and restarting your Mac. You could also try in Safe Mode.
I have not been able to discern a Trend that follows any particular Hardware disappearing.
It seems that my WiFi issue is restricted to one location only. Elsewhere I have no problems: in the train, at home, in coffeecorners, parliament, university. Except that one office where I am the only user under Catalina. On a lower floor in that building WiFi works. I would like to choose 'Forget this network', but that option only appears once connected, right? Perhaps there is some Terminal command to the same effect?
Perhaps I should try creating a location for this spot. I last used the locations feature under OS 7 on my PowerBook 540c.
Hi Ashwin,
Try create one more SSID and connect. It will work. I had similar issue with Mojave during reinstallation and got fixed by creating new SSID in Router. Let me know, if it works. Cheers.
apparently Apple is unhappy with this method of solution and blocked a thread https://discussions.apple.com/thread/250728478...
nevertheless, the solution is not working for me
i personally have a MacBook Air Mid-2013, which is also facing the same issue as mentioned in all Replies... but I hope Apple should at least take a look on all this logging...
you can check your logs by looking for "Console" application in spotlight or launchpad
also this issue is resolved and reappeared from time to time regardless shutting down or sleeping (closing the lid) of my MacBook... so the WiFi connection of mine is purely based on luck currently...
I have tried this on my 2012 MacBook Air as well nothing seems to work after removing the WiFi interface.
Try creating new SSID and connect. I had same issue. New SSID sorted the issue.
