macOS Big Sur 11.5.1 Problems
As we push away from the release we’re seeing complaints about macOS Big Sur 11.5.1 and older versions of macOS Big Sur. Some of the problems are minor and others are far more problematic.
Mac users are having trouble downloading and installing the new software. If your macOS installation gets stuck, try powering your Mac off and on. This typically resolves the issue.
If you’re dealing with installation errors, and you’re using a 2013 or 2014 MacBook, have a look at this guide from Apple.
We’re also seeing complaints about long download times, lag, Touch ID issues, issues with first and third-party apps including Box Drive, iMessage issues, Wi-Fi problems, Bluetooth problems, lockups, freezes, and crashes.
The macOS Big Sur update is also bricking some older MacBook models. The problems appear fairly widespread and they’re mostly impacting owners of 2013 MacBook Pro and mid-2014 MacBook Pro models. These are the oldest MacBook models supported by macOS Big Sur.
Owners of Apple’s new M1 MacBook Pros are complaining about a Fast User Switching bug that leaves them unable to close the screensaver. This leaves the device unusable until the lid is closed and opened again, the Alt-Command-Q key combination is used, or the Power/Touch ID key is pressed. In order to fix the issue, users need to shut off Fast User Switching.
On top of that, macOS Big Sur users are running into a nasty issue with the Apple News application. The popular app is reportedly causing extremely large background downloads for some users. If you’re unsure about whether the issue is impacting your machine, you can check in Activity Monitor.
It’s unclear when or even if Apple will issue a fix so Mac users dealing with the problem are on their own for the foreseeable future. Fortunately, there’s a quick manual fix available. Here’s what you need to do in order to fix the problem:
- Open System Preferences on your Mac.
- Click on Apple ID in the top right corner of the menu.
- From there, select iCloud on the left side of the screen.
- Once there, you’ll want to scroll down and uncheck News to turn off iCloud syncing.
- You can then choose to keep iCloud News data on your Mac or delete it. If you choose to delete it, the data will stay put on your other Apple devices.
If you’re experiencing this issue on your MacBook Pro, you’ll want to get in contact with Apple support because the company will fix the problem for free.
If you haven’t downloaded the latest version of macOS yet, we recommend preparing your Mac for the download. Some prep work ahead of time can help you avoid major headaches.
We’ve put together a step-by-step pre-installation process and it will take you through the best way to prepare for the move.
