Installed OS Sequoia 15.1.1 on MacAir, Not access to internet, no Safari, iCloud, Mac User Guide.

I recently installed Sequoia 15.0.1. I had not access to the Internet, no Safari, iCloud, Mac User Guide.

Today. I installed the new update Sequoia 15.1.1 and I still have the same issue.

I use my laptop for work and this created a problem. The laptop was working perfect before the update to Sequoia. My ESET Cyber Security Pro app asked that I update the OS I had before to the newer one, Sequoia, and even the Cyber Security app works either.


Please, I need help. I would like to uninstall it or do a factory rest to get back to the previous OS.

When I looked into factory reset, it said that it will clear the data & settings but the OS will be the latest that was installed.


Thank you for your help!

MacBook Air 13″, macOS 15.1

The better solution would be for you to uninstall ESET according their instructions. That is likely causing you the problem you are experiencing.

Same here. Ran the update last night and spent 20 minutes trying to figure out what the **** happened this morning. Wifi was fixed by forgetting the network then rejoining. Still can't figure out how to fix the hard line ethernet. I renewed the lease, disabled both IPV4 and IPV6 and re-enabled but same ****.


Kind of a massive fail on Apple's part to break the network connection. Surprised this isn't on any major Mac sites from what I can see. Please make some noise people. This is B team stuff. C'mon Apple. Get your sh*t together.
