macOS Sequoia network issues

So Apple enhanced network security by forcing us to turn off our Firewall when using certain apps like Teams. Niiiice.

The firewall wasn't doing anything for you anyway.

No I said 15.1 which should be released next week.

I ran another test toggling WiFi on/off and ethernet on/off. Now I have both activated once again with firewall on and no issues loading my web page. Odd issue that appears to have cleared itself.

I just restarted the server and it now is working.

not for macbook pro m1

It seems like the 5.1 update has fixed the vexing internet issues of macOS Sequoia. Hooray!

I looked at the wifi site and it says "fixed". It's just that I don't have any previous Sonoma OS backup. I don't know if it's really so, but today I was told by the helpline that on Macbooks with an Apple silicon chip, you can't return the old operating system for a new one. What is your experience?

My configuration is a MacBook Pro 14 M3

Apple releases a new operating system every year. People line up with their download buttons like the biggest Black Friday sale ever held. They will even download special software to hack up their system just so they can run the operating system on unsupported hardware.

There is no number or severity of Apple bugs that could possibly stop this addiction to updates.

This is true, but alas, the urge is too strong to resist. Must...hit...red...button...

I need to download whatever is available for macOS 16x, right now...this is the last time, I swear... :)

For anybody with this issue still, and who are on a corporate machine like me that fortunately is controlled by profiles requiring firewall, VPN, and content filter, you can't turn those off. What seems to have done the job after days of being disconnected/reconnected to company meetings 4x per hour is turning "off" private WiFi address, not just making it static. On static I still had the random high pings to the router whenever things went awry, turning it off made everything smooth as butter at 2-3ms per ICMP request.

If that really is a reasonable short-term fix, shouldn't take much time for security tool vendors to catch up with how the new network stack services are making their requests and processing responses.

After I upgraded to 15.0 from 14.7 I was unable to SSH into any systems. I am using a 2019 16 inch intel MacBook Pro. I am remote using a VPN. I am a Linux system admin so this was an untenable situation. Because of company controls I am unable to disable the local firewall. My solution was to revert to 14.7 using a backup.

Security tool vendors have had access to Sequoia since June.

At first I thought it was my internet service provider or modem. No, it wasn't, but, I now have a new modem coming. Doh! I also tried almost everything listed here on the issue.

I use an ethernet cable and rarely use WiFi on my M1 MacMini. Following a hunch, I turned WiFi ON, got a random message (forgot what it said), then I turned WiFi OFF and the endless internet service drop-outs stopped. It's been working well the past hour. Fingers crossed, for me and all of you!

My Mac is connected via ethernet (prime) and WiFi (backup). I turned off the WiFi and now no issue and web page loads consistently. I have firewall on. Perhaps using WiFi with ethernet disconnected may also work but no time to test at this moment.

Also having intermittent network issues since updated MacOS to Sequoia.

Even after downgrading back to Sonomo, some Macs lose their network connection randomly, either in the middle of the day or in the morning after a reboot.

Reapplying all network settings restores network connection for a while. So, we've created a script that does so that users can fix the issue by running it, but any suggestions regarding is welcome.

If the OS was upgraded in place, its worth trying re-installing the third party protection software. All of my connection loss issues vanished after uninstalling my Sophos Endpoint Protection client. I suspect that the in-place upgrade of the OS with the changes its making to the networking stack isn't playing nicely with already-installed third party software.
