Does Apple still run maintenance scripts as they have in the past?

Thanks

I will defer to a brody expertise above.

You can see more from the terminal man page, copy and paste:

man periodic | more

I would say not like the old days maintenance scripts of OS X, no.

No need for third-party to intercede, typically third party apps add nothing but issue on the new macOS,

launchd has replace cron

Something happens somewhere, you can see the log files...including date & time stamp

from Terminal, copy and paste:

ls -al /var/log/*.out

I guess it begs the question, are you having an issue...?

Backing up is even more essential than this.

Open Applications -> Utilities -> Terminal

sudo periodic daily weekly monthly

at the terminal will run it in administrative login with the administrative password.

Do not run any other commands, until after you restart to avoid any data loss.

This is about the only maintenance I would run. You can run it also by using Screen Saver instead of Energy Saver overnight. If it is not run, it will run at the next opportunity it has.

If you shut down at night every night, it will run at the next restart.

Running it at command line lets you control the time it is run. But normally it runs at some time like 4AM.

Plenty. Maintenance scripts are among them. Gatekeeper is another, maintaining multiple levels of security. There is a background program called XProtect that is part of the system And then don't forget in the dungeons of Mac OS X resides the very active NetBSD and FreeBSD variant of Darwin. Whatever you imagine a good stable Unix system can do, Mac OS X does on its own and very quietly. The Applications -> Utilities folder gives you access to many of the resulting utilities.
