4 Solutions to Fix Mac Error Code 8058

What Is Error Code 8058 on Mac?

Many users have reported this problem after the upgrade to macOS Catalina. To put it simply, Mac error 8058 indicates that Finder preference files got corrupted (we’ll talk in detail about this file type and fixes involving it below).

Why Does Your Mac Give Error 8058?

The main factors that cause error 8058 are as follows:

• Your Mac is infected with malware which could have caused the files to be corrupt.
• The header files become corrupted.
• System bugs.
• Accidental formatting or file deletion.
• Incorrect app installation.

How to Fix Mac Error Code 8058?

To fix the “The operation can’t be completed”… issue and make copying and pasting work again, let’s do some tricks and start from the basic troubleshooting to rid your Mac of error code 8058.

1. Restart your Mac

Before trying any of the fixes below, quit all of the apps and restart your Mac:

1. Click the Apple logo > choose Restart.
2. Log in and check if the issue persists.

If your Mac still gives you trouble and shows the error code 8058, try the methods provided in the next sections.

2. Delete Corrupted com.apple.finder.plist File 

Here’s another fix to the “The operation can’t be completed because an unexpected error occurred”

issue. We’ll deal with a plist file. Property list or plist (for more convenience) is a preference file and contains the preference settings for apps. In our case, we’ll trash a specific plist file that contains the preferences that have become corrupted. 

Here’s how to fix the error code 8058 by deleting a corrupted plist:

1. Quit all the apps. 

2. Click the Finder icon in the Dock > go to the Finder menu.

3. Choose Go > press the Option key to reveal the Library folder option.

4. Look for the Preferences folder.

5. In this folder, look for com.apple.finder.plist file.

6. Drag it to the desktop. If it’s impossible to copy it there — drag the item to the Documents folder.

7. After creating a copy > delete the original plist file by dragging it to the Trash and emptying it.

8. Restart your Mac and try to copy files to your desktop.

Your Mac’s performance won’t be affected after deleting the corrupted plist file. Once you restart your computer, Finder will create a new plist file. This plist file can “recreate” itself.

Note: If you have multiple users on your Mac, you might need to go through the procedure from each user’s profile.

3. Run a Malware Check on Your Mac

Malware might cause the error code 8058 on your Mac, among many other errors. It makes sense to check your Mac for malware if you’ve recently installed new apps or browser extensions. Let’s try these.

You can run a dedicated anti-malware tool or do a manual check. We’ll tell you more about the last one.

A. Activity Monitor 

First things first, let’s check Activity Monitor and detect any app and background processes with malware-infected ones included.

1. Open Activity Monitor > click the % CPU tab and sort processes from high to low. 
2. Check resource-hungry apps, and if you don’t recognize them — google the name to find out whether it’s malware.
3. If yes — quit that process and delete the app.

B. Applications folder

Next, let’s inspect the Applications folder:

1. Open the Applications folder — look through the list of apps, and if you see one you don’t remember installing — use Google to check if it’s trustworthy or not. 

2. If it’s malicious — drag the app to the trash and empty it.

C. Browser extensions

Has your default browser started acting up? If you’ve recently installed any browser extensions, make sure they are malware-free. Read this guide on how to remove malware-related extensions from browsers.

4. Update your Mac

Updating macOS (if your Mac is eligible for an update) is a great move to fix bugs and glitches, thus error code 8058 as well.  First, make sure your Mac can be updated. I’ll try to update my MacBook Pro running macOS Catalina 10.15.17.

To update your macOS:

1. Click the Apple Logo > About This Mac.

2. In the Overview tab click the Software Update button.

3. Wait while your Mac is checking for updates.

4. Click the Upgrade Now/Update Now button.

5. Let the macOS download.

6. Follow on-screen instructions. 

The process is rather time-consuming, so be ready not to be able to use your Mac for a while.

Geek corner: Updating your macOS oftentimes results in data loss. Before getting started, it’s a good idea to create a Time Machine backup. If you haven’t used a backup solution before, you can recover missing files with the help of data recovery software, Stellar Data Recovery for Mac.

Here’s how to retrieve files using the Stellar Data Recovery software:

1. Download and install Stellar Data Recovery for Mac software.

2. In the “What to Recover” window, you’ll need to decide on the file type you want to recover. If you hesitate, choose “Recover Everything” & click “Next”.

3. Select the desired volume in the Recover From window > click Start.

4. Wait for the scan results > press OK. 

5. Look for lost files and recover them.
