The section of the ELOG Administrator's Guide https://elog.psi.ch/elog/adminguide.html describing how to build and install ELOG on a Mac OS X system has worked well for me for several years, even though there have been warnings that the "load" and "unload" subcommands of the "launchctl" command have been deprecated for some time.  After trying my luck again on a new Mac with the latest operating system, I encountered errors of the type "Load failed: 5: Input/output error" when attempting to follow these instructions.

After a bit of searching around, I used information at the page https://www.alansiu.net/2023/11/15/launchctl-new-subcommand-basics-for-macos/ to deploy the more current subcommands as follows:

sudo launchctl enable system/ch.psi.elogd
sudo launchctl bootstrap system /Library/LaunchDaemons/ch.psi.elogd.plist 

sudo launchctl disable system/ch.psi.elogd

Once the above can be verified, perhaps the instructions in the Administrator's Guide can be updated accordingly.

Here's a more complete/correct set of the updated commands:

sudo launchctl enable system/ch.psi.elogd
sudo launchctl bootstrap system /Library/LaunchDaemons/ch.psi.elogd.plist 

sudo launchctl bootout system /Library/LaunchDaemons/ch.psi.elogd.plist
sudo launchctl disable system/ch.psi.elogd

Cheers,
Andreas

Hi Stefan, Thanks a lot for implementing the updated commands. I noted that there are a few typos that could cause people confusion if not fixed:

In one case, "launchctl" is misspelled.

Confusingly, I think the two lines containing the 'enable' and 'disable' commands use the contiguous text string "system/ch.psi.elogd" (no space), whereas the two lines containing the 'bootstrap' and 'bootout' commands use the phrase "system /Library/LaunchDaemons/ch.psi.elogd.plist" (note space after 'system').

Many thanks, Andreas W.
