I restored my mac after getting it back from Apple. It had a busted logic board. After getting it back any download from any browser (Chrome, Firefox, Safari, etc) is flagged by macOS as damaged and should be deleted. I have disabled Gatekeeper and still get the same issue. Any file downloaded via wget or a similar CLI utility work just fine. Does anyone have any idea about what is going on here?

  • Are you thinking Safari isn’t to be trusted and looking for a triage step like new user account, test the ultimate download - an erase / reinstall from Internet Recovery?

  • What model of Mac? What version of macOS? Is the version of macOS up to date with its security updates? Have you rebooted and tried downloading the file again? Have you check the extended attributes on the file and tried removing its com.apple.quarantine extended attribute using xattr from Terminal? Jun 24, 2020 at 11:09
  • Hi Thomas, welcome to Ask Different. You write "any download (...) is flagged by macOS as damaged and should be deleted", is this a message that macOS displays after download? If that's the case, could you add a screenshot of such a message? What kind of files are you downloading (PDFs, video or music files, zipped files...)?

  • I've tried with .dmg, .jpg and .zip so far. The message is shown when I try to open the file from the Downloads folder. I am attaching a screenshot to the original post now.

  • @user3439894 It is a Late 2017 MBP. Restored to Catalina. The file is flagged with com.apple.quarantine. I have attempted to restart the machine, to no avail.
