deleting old installs of 1P

LopezStranded

Thank you for clarifying the situation. It appears to me that the entries in About This Mac>Overview>System Report>Software>Installations are simply a log of what was installed and when, when using a macOS Installer.app package. They are not necessarily an indicator of still-installed applications. To test this theory I downloaded and ran the 1Password 7 installer. A new entry was added to the list. I then removed 1Password 7. The entry is still in the list, despite the fact that 1Password 7 is no longer on my system.

I don't know if Apple makes it possible to delete these log entries — there doesn't appear to be an easy way to do so, which would indicate to me that they don't intend for them to be deleted. Either way I'm afraid we're likely out of scope for 1Password support here. This log is something macOS creates and maintains, and not something 1Password has direct control over.

As for the other items:

The 2nd and 3rd entry are extraneous. You can delete those (perhaps using ⌘Delete as danco suggested). We have a full set of instructions on removing the App Store version to use the version downloaded directly from us, here. If in the future a diagnostic report is required for support purposes you'll want to download the latest version of the troubleshooting utility anyway, rather than generating the report with an old version.
