The operation can’t be completed because an unexpected error occurred (error code -8058).

Hi, I have a similiar problem (error code -36) and am trying to delete the plist lockfile as instructed here. But all I can find is com.apple.finder.plist, I don't see any "Lockfile" anywhere. All I see are two other similar files:

com.apple.finder.plist.eV29S61

com.apple.finder.plist.GM2xXMk

Are these the Lockfiles?

They are not the lock file per se but they are temporary files for the plist.

If you're trying to remedy the problem delete any file with a name that starts

com.apple.finder.plist

When a new file is written, the system will throw some random stuff after the "plist" like you are showing. Then it will delete the regularly named file and rename the new one without the garbage after 'plist'. By getting rid of all such files starting with that pattern above you are clearing the preferences and any failed attempt to store new ones. Clean slate.

Thanks for the help Cerniuk. I did all that and it doesn't solve the problem. The files still won't be moved, copied or duplicated. I keep getting that same error message, just with error code -36 :-/

Sometimes with the problems in the Finder straws and grasping thereof start to look logical.

I am currently looking at every file that the Finder opens and deleting them to see if one or more are the culprit. Here is a list of files that impact the Finder that are located in

~/Library/Caches/

• com.apple.finder
• CloudKit > com.apple.finder
• CloudKit > com.apple.clouddocs
• CloudKit > com.apple.CloudDocs.container-metadata
• CloudKit > CloudKitMetadata
• CloudKit > CloudKitMetadata-shm
• CloudKit > CloudKitMetadata-wal
• com.apple.icloud.fmfd
• com.apple.iCloudHelper

Since the file system is Unix's achilles heel and since "cache file" is nearly synonymous with "corruption" on Unix, I would recommend whacking these files and logging out, then back in. Cache files get recreated by the apps that need them.

I have also found a utility called CleanMyMac which is is not adware and knows a great deal about the system cache files. Utility is not cheap but neither is the time I am wasting chasing these defects around instead of working on my projects. ;-)Recommend grabbing the trial and give it a spin. Macpaw.com Beware, torrents with CleanMyMac carry malware... get this only from the company and you are fine. Info here : https://en.m.wikipedia.org/wiki/CleanMyMac

Thanks. Mine was error -43 and force quiting finder fixed it

Happened to me when I tried to rename a folder when the enclosed file was still open. Closing the file fixed it.
