Error while installing expecting value line 1 column 1 (char 0)

Error while installing expecting value line 1 column 1 (char 0) is a Mac error that may indicate the presence of malware or an update issue. If you get the “Error while installing expecting value line 1 column 1 (char 0)” it’s suggested that you check the system for malware and update it to the latest OS version.

Unfortunately, it is not currently clear what the exact cause of this error message is. As we said, some users have detected malware on their Macs after seeing the error and once they’ve removed the malware, the message stopped appearing. However, it may also help if you update your OS. Some researchers suggest that the cause of the error may be an app update that’s only applicable for macOS Big Sur that got installed on an older version of macOS (such as macOS Catalina or macOS Mojave). In such cases, it could help resolve the error if one re-installs their macOS or updates it to the latest version if possible.

Even if the problem is update-related, however, it is still important to make sure that there’s no malware in the system. In the past couple of years, Mac malware has become very widespread, yet many users still don’t consider it a significant threat. Even if there are no suspicious symptoms on your Mac other than the error message, you should still investigate it and make sure that no malicious or unwanted software has managed to infiltrate your system. Many threats such as Trojans or Spyware are known for showing little to no symptoms and so often the only way to detect them is if you are intentionally looking for them in the system. As we said, instructions on how to detect and remove malware from your Mac will be provided below, so we suggest you go there and complete the steps.

Еxpecting value line 1 column 1 (char 0) Мac Fix

To fix the Expecting value line 1 column 1 (char 0) Mac error, the first thing you should do is remove any unwanted or malicious software that might be in the computer.

  1. Open the Activity Monitor located in Applications > Utilities.
  2. Find and Quit any suspicious processes that might be run by malware.
  3. Go to the Library/ApplicationSupport, scan the recent files with the scanner from this page, and delete anything flagged as malware.
  4. Open the Applications folder and drag to the Trash any potentially unwanted apps.

These four short steps outline the malware detection and removal process that could help you manually clean your computer from threats. However, if you’d prefer a more detailed explanation, you can find it down below, where we will elaborate upon each of those steps and also provide you with some additional tips.

Detailed Guide

Step 1: Quit malware processes

  1. Start by going to Finder, selecting Applications, opening the Utilities subfolder, and starting the Activity Monitor utility.
  2. In it, you should look for processes that are using up significant amounts of your Mac’s memory, CPU, or battery life and that have questionable and unusual names.
  3. Look up the name of each process that you think is suspicious and see what results you can find about it online. In most cases, if the process is linked to any type of malware and/or to the error message, that should come up in the results.
  4. If after your online research you have enough reason to think that one or more processes from the Activity Monitor must not be allowed to run, click on each of them and then select the X in the top-left to Quit them.

Step 2: Delete malware files

  1. Click on the Go menu from the top and select Go to Folder.
  2. Type Library/Application Support in the Go to Folder bar and select Go.
    Goto Folder
  3. In the folder that opens, look for a file named .77B8A707-D8A5-4FBA-AAB9-7475351FDC70 and delete it.
  4. Look for other suspiciously-named files similar to the one above (especially ones that have been added recently) and if you find anything, use the following free online scanner to see if there’s malware code in them:
    Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
    This scanner is free and will always remain free for our website's users.
    This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    • Delete any file that the scanner flags as a threat.
    • In the same way, visit the following folders, scan the files in them, and delete anything potentially unwanted/malicious:
      • Library/LaunchAgents
      • ~/Library/LaunchAgents
      • /Library/LaunchDaemons
      • ~/Library/Application Support
    • Lastly, go to the  ~/Library folder and delete the Cache folder that’s in it.

    Step 3: Uninstall rogue apps

    1. From Finder, go to the Applications folder once more.
    2. In that folder, seek apps that look potentially unwanted to you – ones that you are not sure can be trusted.
      Mac Applications
    3. Pay special attention to apps that you know have been downloaded from outside the Apple App Store – third-party download platforms rarely have the same levels of security so if there’s a rogue app on your Mac, chances are that it has been downloaded from such a platform.
    4. Delete any app that looks suspicious by dragging it to the Trash icon on your Desktop.
    5. Go to the Trash and empty it to complete the uninstallation.

    Step 4: Use specialized software

    As we mentioned in the guide, there’s only so much you could do on your own to remove malware from your computer. If you are still seeing the message even after you’ve done everything suggested in this guide, it might be a good idea to try to use a specialized security tool that can remove any unwanted software from your Mac for you. The removal app we’ve recommended on this page can deal with a wide variety of unwanted and/or malicious software, so it’s a great choice if you are looking for something that can both clean your Mac and also keep it safe in the future.

    Updating your Mac

    If you didn’t find any malware on your computer, or if even after removing the malware that you found, the error message still keeps popping up, then the reason for its appearance may be unrelated to any malicious programs that are in the system. As was pointed out earlier, the other possible cause of this error is an improper update installation. The suggested fix for this is to update your macOS to the current latest version, which, at the moment of writing, is macOS Big Sur 11.2.3. Normally, updates to later versions should occur automatically but if your Mac is still running on an older version of its OS, here’s how you can manually perform the update:

    1. Click on the icon with the Apple logo in the top-left corner of the screen and select the System Preferences option.
    2. Select Software Update and see if there is an available update. If there is, you should see its version and an Update Now button next to it.
      Macos Update
    3. Select the Update Now button and, if asked to do so, provide your Admin password to be allowed to launch the update.
    4. Wait for the update to complete without turning off your Mac.
    5. Once the process is over and your Mac is updated, go to the same Software Update window and check the Automatically keep my Mac up to date if you’d prefer future updates to be installed automatically.

    • Hey, I downloaded Skyhunter for Mac, then performed the scans, a few times, and I am still experiancing the pop up window with “Expecting value: line 1 column” with buttoms that say “Cancel” or “Open(I think, may be it says okay?)”.

      can you help me to fix this and get rid of it finally?

      • Hi, Charles!

        The file name is preceded by a . [dot] so it’s hidden

        Look in Application Support for hidden files using the cmd string:

        Cmd(Command) + Shift + .[dot] will reveal hidden files

        The Malware file path is probably Library/ApplicationSupport/.77B8A707-D8A5-4FBA-AAB9-7475351FDC70

        it is a hidden file – filename starts with a .[dot]

        You can then delete it and see if that resolves your problem
        (or move to another folder if you feel unhappy deleting)


    • SOLVED: For myself there may have been a couple sources of the problem. It has been a week now since I have had no error message displayed. One of the two possible causes was a file in “Library > LaunchAgents” called com.FHilEnLirpnWkxhyqvwjyFrmBeYMAgent.plist. I deleted this file and restarted the MacBook Pro. Unfortunately the error message still kept appearing. The next possible cause was in “Library > Preferences” called com.behenic.peglet.plist. I deleted this file and restarted my MacBook Pro again. It has been one week since then and I have not seen the error message display again.
