MacOS Sequoia installed. Internet will randomly drop connection

Hi


I have a an M2 Max Macbook Pro with 32Gb of RAM. I installed MacOS Sequoia today. After installation, I started getting intermittent random internet connection/server busy messages on a black screen and this will go on for say 30 seconds or more and then randomly it will be back to normal again.


I have restarted the macbook pro. I have restarted the docking station. I have removed the ethernet cable connected and reconnected it after restarting the docking station. I still get the same problem showing up randomly.


Any suggestions?

I've had problems, both on my M2 MacBook Air and my iPhone 15. From what I can tell, these new OS releases interfere broadly with a number of applications, as well—in my case—my eero router. I can't use Proton VPN or Tailscale without losing connectivity completely.


What a disappointing mess of a release from Apple.

Similar situation: m3 max, sequioa 15.0; little snitch (up to date), express vpn, proton vpn as backup.


since updating internet has been very broken despite attempts at troubleshooting and trying to find the cause. I’ve tried all fixes provided, still abysmal. Will probably Time Machine prior to sequioa until things get fixed.

I turned off the rotating MAC address, a stupid idea to start with, as it messes up cached ARP entries on OTHER devices. I deleted little snitch (which was a major source of the headaches). I used Wireshark to note that the default internal firewall ruleset blocks DNS _replies_, even though the state table was supposed to be set up on the outbound query. Nope. So... the Firewall Control Panel entry is not reflecting the true pass/block rules right ? I turned off Intego Netbarrier too, as it is conflicting with some state (who knows what) in the network stack of the os. I am very familiar with pf, so I went in and added an explicit pass rule for DNS inbound/outbound to /etc/pf.conf. Be careful if you dont know what you are doing ! Here's you you prove it, do a dig or nslookup and it wont work until you modify the pf.conf and reload pf. Fixed. It was so broken out of the box that trying to do a Software Update check was failing with "no network connection". I hate lousy error messages like this that dont REALLY tell you anything. The NETWORK connection is not failing, it is DNS inbound which is being blocked, so the calling app hangs. This is another bug, it should time out and give an error "DNS timeout".

There’s an enormous amount of ‘blaming the victim’ going on in this thread, imo.


I’ve been suffering this issue for nearly a month.


Until reading this forum thread (and still, only in this thread) I’d never heard of Little Snitch.


On my Mac the only vpn is a hardware Meraki Z1.


The issue occurs when I am connected via wired Ethernet and WiFi is turned off, as well as when using WiFi.


So to be clear:

CHANGING A SETTING IN WIFI SETTINGS ISN’T NECESSARILY THE SOLUTION.


NOT USING SKETCHY VPN SOFTWARE ISN’T NECESSARILY THE SOLUTION.


If you don’t know the answer, don’t cop a smug, superior attitude and pretend you do.

So 'splain me dis Ricky, why when you try to disable the firewall, it hangs all network interfaces ?

Little Snitch is more than a decade old. It has been a reliable network monitoring software by Objective Development. It's certainly not pirating software! Just alike any application, if you use it unresponsively, that's NOT the fault of the developer. Little Snitch helps to encrypt my DNS request which keeps my browsing secure and most importantly, private! It's like having manageable firewalls for controlling inbound and outbound traffic.
