A

Please enter the following command in a Terminal window in the same way as before:

sudo launchctl enable system/com.apple.PasswordService

Restart the computer and see whether there's an improvement.

B

Some OS X files (Installer package receipts) are missing or invalid. Other OS files may also be missing or invalid.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.

*The linked support article refers to OS X 10.11 ("El Capitan"), but the procedure is the same for OS X 10.7 ("Lion") and later.

C

Please sign out of iCloud in its preference pane and see whether there's any change. No data will be removed from the servers, and you can retrieve it by signing back in. That said, you should always have a current archiveof the data for safety's sake, even if you don't sign out.

If you use iCloud Keychain, when you sign back in to iCloud follow one of the procedures described in this support article to set it up on an additional device.

D

The test results show other issues, probably not related to the original question.

Remove the Sophos product by following the instructions on this page, and also this one, if applicable. If you have a different version, the procedure may be different.

Back up all data before making any changes. Never install any "anti-virus" or "anti-malware" software again.

E

You're on an unsecured Wi-Fi network. If it's your network, that's very dangerous. Change your router's settings so that it uses WPA 2 Personal encryption. If it doesn't support that standard, it should be replaced. I can't give you specific instructions for changing the setting, because all routers are different. Refer to the manufacturer's documentation.
