No internet after Sequoia 15.1

Just what it says. Downloaded and installed but my M1 MBP can’t get online with wired, WiFi, or hotspot to my SE3. Settings don’t seem to be out of order. VPN off. Fast fiber connection with all other devices in the house. It’s late so I’m going to bed and hope it sorts itself out (haha). Which means I’ll probably be on the phone with Apple unless a gracious MPU guru can set me straight.

But hey, the new screen savers are neat!

Sequoia is a god damn NIGHTMARE.

I knew I was going to kick myself for originally upgrading but I was just so eager to use the new features. I get kernel panics constantly, iMessage VPN bug, network packet filter w/ VPN bug, and every few days my Mac Mini M2 Pro has restarted.

This is one of the worst operating systems Apple has ever released. It’s that bad and I am so frustrated. 15.1 didn’t fix the kernel panics or the “Your computer has been restarted” issue.

TLDR: It was some Little Snitch cruft.
Solution: Find all the Little Snitch cruft and delete it.

Excruciatingly verbose story I’m not advising you to read:

First thing this morning, I got on the phone with Apple Support, pretty knowledgeable guy and we went through the litany of settings, reboots, deletions, but no luck. He ended up telling me to check with my ISP, to see if this MAC address was blocked. I couldn’t get a clear answer from him as to why the ISP would block this particular MAC address but, hey, stranger things have happened. AT&T has a home monitor app so I checked that and it showed that the MAC address for the MBP was unblocked. So back to square 1.

Called Apple support again with a case# this time and got someone who sounded much less sure of what she was doing, as it sounded like she was reading off a list. We went through a lot of the same steps, plus entirely deleting the VPN software (NordVPN) even though it was off. Of course, that didn’t help. We started going through plist stuff and looking for “files that look unusual” I figured she was just throwing everything at the wall to see what would stick. Which is what we were doing. The next few steps seemed like that. We deleted all the login items too, but since we were on that screen I scrolled through “Allow in the Background” which she said should be fine, I noticed “Little Snitch” which I haven’t used in a long time. I thought it was deleted, and it was not in my App list. I either disabled or deleted some cruft I found somewhere, and I got a notification that “Little Snitch has installed…” something. I forget what.

That sent me down the Little Snitch rabbit hole. I employed Clean My Mac via Setapp, which helped me discover some more LS cruft, which I deleted. This was while the Apple tech was giving me other directions, so my memory is a little fuzzy on this step. Regardless, a closed out of everything else and all of a sudden got a notification about making WiFi calls. Hmm. I opened up a browser and was back online.

I went to the LS website and they explained that the usual delete process might not work due to a “bug in MacOS” and that the solution is to reinstall LS and uninstall it a different way. I downloaded and installed LS to try this alternate method to hopefully insure I got all the cruft. LS is happily humming along right now, while I am successfully browsing in Brave, with Nord reinstalled and active, with Sequoia 15.1 running the show. I haven’t uninstalled LS yet, although that should come next.
