Archive Utility Fails To Expand All Files

jonnykjon,

Got it. Ensure your Mac is completely up-to-date Update macOS on Mac. macOS Catalina goes up to 10.15.7.

If it is fully up to date, see if this happens in safe mode by following How to use safe mode on your Mac. This can help determine if there is software running on your Mac that is preventing it from doing this.

Best regards.

Hello jonnykjon,

Thank you for reaching out to Apple Support Communities.

Are you using these steps to unzip files:

"On your Mac, do any of the following:

• Compress a file or folder: Control-click it or tap it using two fingers, then choose Compress from the shortcut menu.
• If you compress a single item, the compressed file has the name of the original item with the .zip extension. If you compress multiple items at once, the compressed file is called Archive.zip.
• Unzip (expand) a compressed item: Double-click the .zip file.
• The unzipped item appears in the same folder as the .zip file. If you want to, you can delete the .zip file.
• Note: If you can’t open the .zip file, make sure you have enough space on your Mac for the unzipped item. If you received the .zip file from someone else, there might be a problem with the file. Ask them to zip the file again and resend it."

More details can be found here: Zip and unzip files and folders on Mac

If yes, can you provide a few more details? Which macOS version are you currently using? Are you experiencing this with all .zip files or just certain ones? Also, when did you first notice this?

Cheers!
