New updates are being added at the bottom of this story…….

Original story (published on November 24, 2020) follows:

The macOS Big Sur update is probably one of the most feature-rich updates that Apple has released recently for its macOS machines.

It carries several improvements and even brings one of the biggest UI overhauls to macOS, bringing it more in line with the UI offered on iOS 14.

Of course, a quick Google search will serve you dozens upon dozens of articles detailing all that’s new and the same goes with videos on YouTube.

But before getting excited about the new features and improvements, it’s also worth noting that, like most other software updates, the macOS Big Sur update also has its fair share of bugs and issues.

Take for example the bug we reported of earlier which prevents some MacBook users on Big Sur from booting their devices while connected to a monitor via Thunderbolt.

Now, another issue appears to be troubling many Mac users. After installing the macOS Big Sur (11) update, users are reporting that the printing function is now broken.

We’ve shared multiple reports from affected users below:

Printing went well on Catalina. Now printing stopped and showed message ‘Filter failed’. Using printer Lexmark C543 and removed and entered the printer once. Same problem. Printer supply is visible in browser. Seems to be OS problem. (Source)

Same problem overher with my Lexmark CX310 when i print. Printer receives nothing it even does not even wake up. Tried to install new drivers from Lexmark but this is also resulting in an error so new driver are not installed. (Source)

My company we run a Canon C5035, we updated all the iMac 2019 and MacBook to OS Big Sur…Now when we print the text comes out as gray squares. This is a monumental problem for our business. Please provide support ASAP. (Source)

I already updated the latest version MacOS Big Sur Beta 11.0 (20A5384c) but after updated i got some issue in printing the documents. In first beta update document printed but only pictures are printed no paragraph is printed. After second update my new printer HP Laser jet Pro M15a installed but not printing even no error showing. Need support on it. (Source)

As you can see, the problem seems to be affecting users with all sorts of different printers. Therefore, it certainly cannot be pinned down to a certain printer model or even brand for that matter.

At present, the problem has not been acknowledged by Apple directly, although it does have a general fix for printing issues that we’ve shared below.

Furthermore, what seems to be the most likely issue is the printer drivers or rather, lack thereof, as highlighted by a user and a report.

I was able to print using a USB cable though, after downloading the latest driver and connecting to the printer via an old USB type 1 cable that I had around. Seems like Epson needs to update their driver software. (Source)

Most printer manufacturers are yet to release new drivers with support for macOS Big Sur. Therefore, it’s more than likely that most issues would be fixed once the updated drivers go live.

But until then, you might want to try these possible workarounds which may fix the problem for you.

Workarounds for printing issues on macOS Big Sur

1) Reset the Mac printing system (official fix):

1. On your Mac, choose Apple menu > System Preferences, then click Printers & Scanners.

2. Press and hold the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears.

3. After you reset the printing system, the list of printers in Printers & Scanners preferences is empty.

4. Re-add any printers.

This should fix the issue for some users, however, there are chances that your printer might not work even after performing the steps above.

2) Download the open-source Gutenprint driver:

It seems that users have managed to fix the problem after downloading and installing the Gutenprint driver which is completely free. All you need to do is download the latest package from here and install it on your Mac computer.

3) Check for the latest drivers:

Make sure that you have the latest drivers for your printer installed on your Mac computer running macOS Big Sur. There’s a possibility that the current printer drivers aren’t supported on the latest OS.

Therefore, updating the drivers to the latest version might fix the issue for good. Most manufactures provide the drivers on their websites so you should be able to get your hands on the drivers within a few minutes.

That being said, we will continue to keep an eye out for any new developments regarding the broken printing function on macOS Big Sur and will post an update once new details emerge.

In the meantime, do let us know whether any of the workarounds provided here helped you fix the problem. Further, feel free to let us know if we missed out on a workaround that helped you fix the problem.

For Lexmark users still experiencing this issue, someone seems to have found a workaround and we’ve shared it below.

For Lexmark printers (is what I have…) just install the same driver for your printer using in the “use” drop menu the Generic PostScript Printer.

Another couple or so users also say turning to AirPrint instead of USB does the trick for them, so you should try it too if your printer is supported.

I tried your solution and it failed 30-50% of the time to print. Instead of selecting the Lexmark driver (even though installed) I selected AirPrint- viola! 100% success rate so far.

Update 2 (March 12, 2021)

Going by reports, it appears the problem continues to persist even in the recent versions of macOS Big Sur ( i.e. 11.2.2 and 11.2.3).

Going by the information shared by one of the affected users (with a Canon printer) deleting the printer and re-installing from the official website did the trick for them. Here’s what they shared:

Hi! This solved my problem. Running 11.2.3 MacOS BigSur MacBook Air 2017 model. Using Canon Pixma MP237
Just delete the printer and download & install this from the canon website. Copy the URL below and remove the space between h and t in the “https” before clicking enter.

Common macOS Big Sur Update Stuck Problems & How to Fix Them

1. Big Sur Update Download Stuck

As you attempt to download macOS Big Sur installer, you may be noticed that 'Installation requires downloading important content. That content can't be downloaded at this time. Try again later.', or 'An error has occurred.' Big Sur download times are slow this year and are always failing. It's exceedingly annoying, but there is no way to bypass this step for macOS update.

Usually Mac update download failed error is originated that you download the package from somewhere other than Mac App Store or you just downloaded the Beta version. So you need to go to Mac App Store and download the official macOS Big Sur instead to fix it. Overloaded Apple's server is also a main cause.

3. Failed to Update macOS Owing to Insufficient Storage

You know, Big Sur update requires at least 2GB RAM and 14.3GB available storage. So if your Mac computer almost ran out of the storage space, your macOS update stuck at the beginning for sure. To make sure how much space your Mac has left, from the Apple menu, select About This Mac >More Info >Storage.

If your Mac update failed definitely owing to the storage space, the only thing you need to do is to free up the space on Mac. Just make it done by uninstalling unused applications and app caches, deleting old devices backups, deleting unnecessary media files from iTunes, emptying trash can, clearing temporary files, compressing large files to smaller size and so on.

4. macOS Big Sur Update Freezes on Firmware Confirmation

The inability to verify firmware error is the mainly reported macOS update problems. Many users said as they try to update to Big Sur, the installer noticed that there is an error checking the firmware. Actually, it turns out to be a corrupted EFI partition. It's an MS-DOS formatted little slice that's needed when updating the computer firmware.

You can boot into rescue mode, checked the partitions with 'diskutil list' and 'verifydisk' (terminal), and fixed the EFI partition 'diskutil repairdisk (your EFI disk/partition) '.

After downloading the new macOS for my MacBook pro (mid-2012) with HDD, the computer restarted but continues to fail during the installation. The error I keep getting is .

6. Big Sur Update Stuck on Gray Screen

It's not always a gray screen, as strange as that may sound. The 'gray screen' problem can also manifest itself as a black screen, space screen with Apple logo, a spinning gear, a spinning globe, or a prohibitory sign. Mac update stuck on gray screen problem can occue right after you start or restart your Mac. It may be caused by a bad peripheral or peripheral cable, RAM issue, Drive issue or whatever.

Before you start to fix the macOS update stuck on gray screen problem, you need make sure what's the cause. Then you can disconnect all external peripherals, remove all but the minimum amount of RAM from your Mac, use Single-User mode to repair a Startup Drive. I think the problem will be fixed.

After you have fixed the macOS Big Sur update stuck problem, you can enjoy the salient new features of Big Sur. But at the same time, some new troubles might trouble you as well, such as like macOS Big Sur running slow, some apps get damaged or non-Apple Apps cannot be opened, Safari crashed, Mac gets overheated, or the Big Sur keeps logging you out etc. So think twice before you upgrade to macOS Big Sur, and if you encounter any Big Sur update problems, pick the macOS update problems and fixes as a reference.
