Error code -36 after macOS 11.5.1 update

Try the restart in Safe Mode and see if the issue is presented in this mode. Suggest you run this way long enough to Test.

Should it happen in Safe Mode - there might be a system wide issue or user account issue.

Hi all,

We're noticing the same issue here in my environment. I have ran the following solutions thus far on an M1, Big Sur 11.5.2:

1. Creating screenshots that are saved onto the desktop are getting the Error Code -36
2. Ran dot_cleaner ~/Desktop + reboot. After logging back in, deleting the screenshots/files we had on the desktop worked, however after the third attempt, the error -36 came back
3. Updated the system from within recovery mode to 11.5.2 rendered the same exact results
4. rm the file(s) in questions in Terminal (usually located on the desktop) works.

The dot_clean command worked for other users after the reboot but this one system in particular seems to only work for the first two attempts (while trying to delete a file), but eventually gets the error again.

Any clue or ideas on what else to try?

Thank you all ahead of time for any response...

Two things - have you tried the possible solution from the link ?

If yes and still and issue, there might be some third party software interfering with the normal operation of the OS OR in your user account.

To determine Third Party software issue >> Suggest downloading the Application Etrecheck directly from a Trusted Developer and well Respected ASC Contributor. The application is free or paid from added features. Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ). It will take a Snap Shot -  both the hardware and software. The Report will Not Reveal Any Personal Information. Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.

Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.

So far so good - the issue has not returned after I removed an obviously malfunctioning Tunnelblick app from startup 👍

Thanks for the hint with Etrecheck - I didn't even know I had Tunnelblick on a startup list 🤷‍♂️

Always advised —Uninstall any and all third party Antivirus, Cleaners, Optimizers, VPN, speeder uppers....

I trust this resolves your issue.

Yes, please do keep us updated - if time allows

I'm getting Error Code 6 when I try to access information from my external hard drive on my M1 computer (MacBook Air).
