Overview
- Apple’s macOS Tahoe 26.4, released this week, now shows a Terminal popup when users paste commands from other apps, according to reports shared by Mr. Macintosh and echoed on Reddit and X.
- The alert reads “Possible malware, Paste blocked” and explains that scammers push Terminal instructions via websites, chat agents, apps, files, or phone calls.
- Users can choose to paste anyway or stop the paste, giving a clear checkpoint before a command runs.
- Testers report the prompt does not appear every time and the exact triggers are unclear, with one follow-up noting it may show only once.
- Outlets differ on how widely the feature appears, as MacRumors saw user reports across platforms while AppleInsider could not reproduce it on some installs, and none of the coverage cites an official Apple explanation.
