Hello @TwinTraveller! 👋

I'm sorry to hear that you're seeing performance issues with 1Password 7 on your Mac. Our developers are indeed investigating an issue with 1PasswordSLSNativeMessageHost and we hope to include a fix in a future update. In the meantime you can force quit all 1Password processes on your Mac and then restart 1Password to workaround the issue:

  1. In the Finder, click Go menu > Utilities.
  2. Open Activity Monitor and click the CPU tab.
  3. Search for "1Password"
  4. Select all matching processes with ⌘–A or Edit menu > Select All.
  5. Click the 🛑 Stop button in the toolbar and Force Quit.
  6. When all processes disappear, reopen 1Password normally.

Thank you for reporting the issue and I'm sorry for the inconvenience, I've added your report to the internal tracking item that our developers have open. Please let me know if you have any questions.

-Dave
