Software update issues with macOS Sequoia

My users are experiencing issues with the internet and firewall after the macOS Sequoia update. Unfortunately, version 15.0.1 did not resolve these problems.

Is anyone else encountering similar issues?

With over 2 billion customers no matter what problem you have it is virtually certain that there are other users with a similar issue. But how does knowing this help you?

What specifically are the issues your users are seeing? I would expect that there are dozens of possible causes of networking issues, because there are so many layers to communications protocols (7, actually). But without knowing what the issues are there is no place to start troubleshooting.

1. Unknown, weird language appears on Mac OS Sequoia 15.0.1: Example: Í˚ÎÏÔÒÍ˚ÏÅÍÎÏÍÅÏÍÏÍÎÏÍÏÍÎÏÍÏÍÒÍÎÍÅÎÏÔÅÍÒ˚ÎÏÍÅÏÒÔÍ˚ÎÏÔÅÒÍ˚ÎÏÔÒÅÍ˚ÔÏÒ˚ÍÔÏÒÅ˚ÍÔÏÒ˚ÍÔÏÅ˚˚ÎÏ©˚
2. Finder issue: Random folders open instead of the one clicked.
3. Applications keep shutting down: Adobe Illustrator keeps asking to save files even after they've been saved.
4. Keyboard issue: Lowercase letters change to uppercase in the middle of typing, even when Caps Lock is off.
5. Application issue (Gmail, Outlook, company chat): Clicking buttons opens new windows, prevents moving to the next step, window stops responding, can't scroll.
6. Display controls not working: Brightness controls pop up but don't respond to clicks.
7. Copy-paste function not working.
8. THERE ARE SO MANY ISSUESSSS

These issues are affecting workflow, and it feels like the system might be compromised. Immediate fix needed.

The fact that you are having those issues doesn't mean that everyone or even most people with Sequoia are. In fact, most people aren't.

Okay, what troubleshooting steps have you taken yourself? What did Apple say when you contacted them to evaluate the issues?

The Sequoia update has basically bricked every Apple native app on my iMac. It is not just Safari, it is also Mail, Music, Photos, etc... The only native apps that still work are Notes and Calculator. I guess the ones that don't connect to the internet.

Apple please fix ASAP!!! Either that or give us an easy way to revert back to a OS that works.

Should have remembered your advice James. 15.1 is a complete mess. Won't recognize my external monitor, my external speakers and changed a bunch of presets I had set in 15.0. Wished I'd never upgraded.

Mac Mini M4 Sequoia has many issues. This is the first time Mac gave me problems.

Printer Issues: After replacing the ink in Epson printer, the Mac Mini M4 still wouldn't detect the printer's status correctly. After removed the printer in Sequoia, and added it back to get it to work. I even bought HP Laser. Found another problem. Sequoia won't scan pdf document from the printer to Mac Mini.

PDF Problems: The Page won't open PDF files. Intel Mac never have any issues with pdf or pinrter. I installed LibreOffifce. After edited a PDF in LibreOffice, converted it to ODT, then exported to PDF. I thought I can keep MacMini and it solved pdf issues. After opened PDF, it is garbage text. (smeared and unreadable).

VMware Fusion Compatibility: After installed VMware Fusion, it shows blank media.

While the M processor is great for gaming and video editing, it is lacking for business-related tasks like handling PDFs, printers, and virtualization.

In the end, I return the Mac Mini and purchase a Lenovo Ideapad with an Intel Core i5 processor, 16GB of RAM, and a 512GB SSD for just $499 (on sale from $859). The Lenovo is running smoothly without the issues.

While I am not a fan of Windows 11, the Lenovo’s performance and reliability made it the better choice for my work, especially compared to the Mac's problems.

Interesting that I have NONE of those problems on my M1 MacBook Pro.

I use it for business related tasks all day, including PDFs, MS Office, printers and virtualization. I have 2 monitors and 6 virtual windows on the 27 inch external monitor, plus one on the MBPs screen, and I have typically a dozen or more apps running simultaneously.

For VMware Fusion it requires an ARM version of Windows, which is available on the Windows support site.

Pages app is not for PDFs, which are opened in the Preview app.

Sequoia works perfectly with my HP all purpose with scanner, and also my Doxie scanner. And it reports the status of my printer whenever I ask. I gave up Windows almost 20 years ago for MacOS, and found it much more reliable, secure and, when I needed Windows, I used Fusion. As I don’t need Windows anymore, as MS 365 is available for Mac, I also got rid of Fusion.

Too bad you had unusual problems, but they were certainly solvable. But enjoy your Lenovo!

I have updated to XCode 16 with MacOS Sequoia. Run with no issue on my MBP M1 16 GB and 1TB SDD

Good to hear.

Yes, after downloading Sequoia I can not open Safari. Spent all day with support, no solution

Apart screen flickering and memory leaks on Finder I didn't encountered any other issue on Sequoia.

Start by uninstalling BitDefender.

I did, and it made no difference.
