ME:: this seems to work on macOS Big Sur 11.7 ; huksley's github gist:: Disabling photoanalysisd on macOS

The following seemed to work on 11.7, note that this changed slightly in Monterrey and later ; read the gist for those newer macOS versions:

launchctl disable gui/$UID/com.apple.photoanalysisd launchctl kill -TERM gui/$UID/com.apple.photoanalysisd
