MacOS Sequoia 15.4.1 Extremely Buggy

[Tenarrows]

My iMac has been extremely buggy and I believe these issues might have started with the latest OS update.

(1) iPhone Mirroring fails to connect most of the time. I receive an error message instead. I tried closing and reopening the app.
(2) Messages app which I leave open but minimized closes on its own in the background.
(3) Mail App in doc stopped showing the number of new emails.
(4) iMac has crashed at least one time.

There maybe other issues but those are the ones that come to mind. Ive tried restarting the computer, scan disc and first aide and neither has resolved these issues. Are these known bugs with the latest OS and are there any fixes?

My specs as listed in the subject line are MacOS Sequoia 15.4.1.

Thanks in advance.

What method did you use to perform the update? I experience none of the issues you listed above, and I’m running macOS 15.4.1 (24E263) on my Mac16,9. #1 to #3 on your list are working flawlessly and #4, I haven’t experienced a single crash since I started running it almost two weeks ago. I’m so pleased at how it’s working right now that I’m tempted to install the latest beta version of Sequoia, macOS 15.5 beta 4 (24F5068b) … but maybe not yet. In a couple of weeks, perhaps.

You may want to reinstall Sequoia, and you may have to do it through Recovery because I don’t know yet of any place where you can download the installer app by itself. … But I just checked on Terminal and it looks like macOS Sequoia, Version: 15.4.1 is now available for download. For all you know, a reinstall might be all you need to fix your issues. Good luck.
