Internet connectivity problems after changing to macOS 27.0 Golden Gate

A couple of days ago, I allowed my Mac's Software Update to change the OS from macOS 26 Tahoe to macOS 27.0 Golden Gate. I've had some serious problems since then and would like to revert to macOS 26 if I can do so without too much disruption. However, from what I've read on the Internet, restoring a Mac to a working version of the OS seems like a nightmare that involving wiping the entire hard drive, install a working OS from scratch and then restoring from a backup made before the OS change (which would mean losing several days of work).


The worst problem I'm experiencing is internet related problems that manifest after the computer wakes from sleep. After a wake, all streaming content on the internet becomes unavailable. For instance, any Amazon Prime video stop playing, replaced by a message "Video Unavailable". Similarly, Netflix freezes up with a message "Pardon the Interruption". Also, ebay won't load at all; I just get a spinning wheel that never stops. YouTube videos won't play. Etc. On the other hand, some other internet connections do work. I can do Google searches. I can visit some web sites, such as Wikipedia. However, it seems that nothing that requires an ongoing connection where the web site needs to "know" who I am, works.


This happens even after a brief period of sleep. For instance, if I go to the kitchen for a few minutes to get a snack and the screen saver is on when I get back to the computer, the Internet is out until I reboot the computer.


I've tried all kinds of things like reloading pages, deleting tabs and revisiting, switching browsers, etc. I've fiddled with a lot of the network settings. I haven't found anything that restores the Internet other than rebooting the computer.


I really don't want to continue using macOS 27, but if I can solve the more serious problems, like Internet issue, I'll live with it rather than wipe my hard drive.

Second follow up. Unfortunately, I found that the trick of closing and reopening the lid of the laptop did not always work. In some cases, I had to do it multiple times and in some cases, I'd have to resort to rebooting.


But, I found another workaround that's been reliable so far. The clue is that when the internet wouldn't restore, some of the streaming web pages would show an error message to the effec that the audio would not initialize and I should reboot my device. There are about half a dozen options for audio driver in the Sound tab of user preferences. Cycling through them has no effect. However, one of the is built into an external monitor. I found, after much experimentation, that if I turn off the power to that monitor, and then turn it back on, the Internet kicks back on immediately. This is the case even if the web browser and the sound were not on that monitor at all.


So, my revised theory, is that macOS 27 has a bug involving reinitializing audio drivers after going to sleep. Any device that has an audio device in it, needs to be physically power cycled after macOS 27 goes to sleep. Otherwise, any service that could employ audio will become blocked and not function.


Hey, Apple. I'm looking for a job. And, I'm already doing your job for you ...

I stumbled on a way to get the internet back without rebooting. I'm using a MacBook Pro (as indicated in the post). When I work at home, I have it plugged into an external monitor. When the computer goes to sleep and then wakes, I lose the Internet. What reconnects it, is to close the lid of the laptop, wait a few seconds, and then reopen it.


Note that, the laptop appears to be completely "awake" before closing the lid. Also, this action was certainly unnecessary in macOS 26. It seems that there's a bug in macOS 27 that prevents it from fully waking unless you physically close the lid and then reopen it. A bit of a nuisance, but better than having to reboot.


I hope someone from Apple is listening.

This is happening to me too but it also happens after a restart. I'm using a MacBook Air (2022) and an Eero pro 6 router. I thought maybe there was an issue with the router but all my other devices connect, and maintain connection, to the internet just fine. It's just the MacBook Air and it started right after the upgrade to MacOS 27 Golden Gate. The MacBook Air will show connected to the wifi but no internet connection.


I like your idea about the external monitor, but this happens to me regardless of wether the MacBook Air is connected to an external monitor or not.


The one workaround I've found that works for me is to switch the MacBook Air's wifi connection my phone's hotspot. After a few seconds, I switch the connection back to my home wifi and the internet connection is established. MacBook Air will remain connected to the internet as long as it is awake and active. Once it goes to sleep, it maintains the connectivity to the wifi SSID but loses internet connection and I have to repeat the process once it wakes. Same thing happens when I restart or boot-up: no internet connection even though it's connected to the wifi network. Then I have to repeat the process of switching wifi back and forth.


I'm not glad we're having issues but I'm glad I'm not alone. Hopefully Apple will find the cause and send a bug fix in a future update.

If all else fails do not use sleep. Just have display turn off after a set time and test.

Same here. On top of that, when I lock my macbook, the wifi icon on the lock screen appears as inactive (hollow). Wifi connectivity is lost after several hours of sleep mode. Really annoying and disappointing, especially after an impeccable user experience of mac OS Tahoe. Totally regret switching.

Thanks for the information, this has been driving me crazy as I have to step away from the computer a lot and have had to restart several times throughout the day. I use two external monitors with my lid always closed. I had tried restarting the browsers, disconnecting wifi and reconnecting, and etc... only thing that worked was restarting the entire computer. Thanks again for the work around.

I'm not sure what you mean by "sleep" other than the display turning off. In the battery settings there's "Low Power Mode", which I have at "never". What settings are you referring to?


Do you have a lock screen in your systems settings.? In that menu you select to turn off display after a set time

My computer MacBook 2020 will not connect to the internet but is connected to the WiFi. I just downloaded golden gate . Help!!

I also have the same problem and it’s annoying that everytime I close the lid Internet disappears.
