Jeffery,
Sorry to hear you're having problems.
Thank you for sending a diagnostic report. This helps immensely.
It appears from your report that you have relocated your home folder to a different volume. This greatly complicates the QRecall installation. Privileged executable, system daemons, XPC services, and some user agents must reside on the startup volume. For security reasons, macOS won't launch some executables if they reside on a non-startup volume.
To work around this limitation, QRecall relocates some of its components to a special system directory when the user's home folder is not on the startup volume. Specifically, it creates this path:
/Library/Application Support/QRecall/504
where "504" is the UID of the user installing QRecall.
Somehow, your installation has gone sidewise because this directory has the wrong owner:
ls -l /Library/Application Support/QRecall
drwx------ 6 505 80 192 Mar 17 19:47 504
-rwxr-xr-x 1 0 0 19152 May 12 2018 QRecallKickStart
ls: /Library/Application Support/QRecall/504: Permission denied
The "504" directory is owned by user 505, not 504, and QRecall (running as user 504) can't see or modify the components in this directory. So the installer steps fail, and anything that is installed there won't launch.
The other problem logged is "Failed to install Privilege Elevation service", which indicates you have a mis-installed privileged helper. This sometimes happens in macOS, where you go to install a privileged service, macOS prompts for administrator's authorization, and then something goes wrong. The helper doesn't get installed, but macOS won't prompt to replace it, and you're stuck with a non-functional installation.
To rectify both of these, I would suggest the following:
Delete these paths:
/Library/LaunchDaemons/com.qrecall.hoist.plist
/Library/PrivilegedHelperTools/com.qrecall.hoist
/Library/Application Support/QRecall/504
Restart your system
Launch QRecall and let it reinstall itself againThis will eliminate the mis-installed support folder for user 504 and manually un-install the privileged helper.
Please send a diagnostic report afterwards so I can verify the correct installation (and look for possible QRecall bugs in how your situation was handled).
