automount not working after macOS Catalina updates

I’ve recently upgraded to macOS catalina. My automount mount for music media was broken. I fixed it and today it is again not working.

The last change I did was to install the supplemental update for 10.15.7 which seems to overwrite the /etc/auto_master so my /etc/auto_smb wasn’t loaded anymore. Here’s my current working content:

#
# Automounter master map
#
+auto_master		# Use directory service
#/net			-hosts		-nobrowse,hidefromfinder,nosuid
/home			auto_home	-nobrowse,hidefromfinder
/Network/Servers	-fstab
/-			-static
/-			auto_smb	-nosuid,noowners

Don’t forget to run

sudo automount -vc

after it you’ve changed the file. Your automount should now work again.

Fix broken automount mounts on macOS Catalina

I’ve moved my iTunes music library content to my NAS. I’m using automount to keep iTunes happy without losing the connection to the files. After upgrading to macOS Catalina, automount did not work as it used to.

Reason is the changed structure in the APFS container. If you have a look at the disk utility, it will show you a system container and a user container. The system contains macOS and is write protected, while the user container contains all your apps, data and so on.

You’ll just have to prepend your existing automount paths with /System/Volumes/Data. Now you’ll just have to run

sudo automount -vc

and the automounts are working again.

I had to change the iTunes settings back to my automount folder, as the upgrade to Catalina reset it to its default location in your users folder.

Disable macOS Catalina update notification in Mojave

macOS Catalina was released and is ready to install. If you’re using the previous macOS version called Mojave, you’ll get a notification badge on the system settings.

This little red notification badge is really annoying.

The following two commands were taken from the Apple support forum:

sudo softwareupdate --ignore "macOS Catalina"

If you want to install Catalina via the software update, you can reset the ignored updates with this command:

sudo softwareupdate --reset-ignored

This will hide successfully the Catalina update from the list of available updates in Software Update. However, it won’t remove the notification badge.

But fortunately you can even disable the badge by using these commands:

defaults write com.apple.systempreferences AttentionPrefBundleIDs 0
killall Dock

This will hide the badge until the next time you’ll scan for available software updates.
