The 10.15.3 Update Erases almost all of the log files in /var/log – System, Custom & Vendor Logs
The 10.15.3-10.15.6 Update Erases Almost all /var/log files
UPDATE: 09/01/20 – The problem is still in the latest build of 10.15.6.
Think about the last issue time that you had an issue and needed to troubleshoot. Right off the bat, you would start looking over the logs to pinpoint the exact point of failure. After installing the Catalina 10.15.3 Update, it’s going to be a little harder to do that. Almost all the /var/log files have been erased and start over the minute after the 10.15.3 update finished installing.
10.15.3 Update Problems
This is my 4th article on 10.15.3 Combo Update issues. If you have not seen them yet, you can view them below.
All log files have the exact “Created” date and time when the 10.15.3 combo update was installing.
Almost all /var/log files erased and have the same “Created time”. The install.log was spared.
What can I do about this?
Let Apple know about this! Hopefully this can be fixed in 10.15.4!
Until then you probably want your log files. The best thing you can do for now is to run a Jamf policy that will backup your /var/log files. We install our updates with a Jamf policy.
Right before we kick off softareupdate -iaR we backup all /var/log files to a temporary directory. We put them back with a LaunchDaemon that kicks off after the combo update reboot.
I hope that these articles have helped you! If you have any questions, leave a comment below or Contact Me.
How to Manage Catalina’s New Application Notifications with a Profile
This article will show you how to Manage Catalina’s New Application Notification Preferences with a Config Profile.
Now that Catalina is live, MacAdmins have many questions. The top 3 questions I have seen so far are;
1. How do I block macOS Catalina from my users?
2. How do I Manage macOS Catalina Application Notifications?
3. What are the new Screen Recording and Input Monitoring or Keystroke Receiving TCC Settings? (more on that in a new article.)
Catalina Application Notifications Index
1. Should I manage Application Notifications?
2. How do I reset or clear out previous Notification Settings?
3. How can I test the Notifications Profile?
4. Find Previous Bundle ID or App Domains from past Prompts
5. Manage Notifications with a Profile.
6. Notifications Profile with Profile Creator.
7. Notifications Profile with Manage App Notifications.bash

1. Should I manage Application Notifications?
This is a question you should ask yourself. Keep in mind, once you mange a profile setting it can not be changed by the user. Managing certain application notifications from Jamf Self Service is one example. You WANT the user to be able to see the notifications that it sends out. The user may miss something important, if they previously clicked DENY. For other applications, you might want to leave Notification decisions to the user.
2. How do I reset or clear out previous Notification Settings?
How do you reset Catalina’s Application Notifications if you clicked Allow or Deny already?
The settings are stored in a plist in the users /Library/Preferences folder.
com.apple.ncprefs.plist
To reset all Notification Alerts, you can delete the plist and then restart. Once you get back to the desktop all your notifications will start popping up again.
3. How can I test the Notifications Profile?
After you create the profile and install it, any open notifications will immediately disappear! The best way to test your new profile is to delete ncprefs.plist, then restart. Then you can leave any open notifications up on your desktop. Install the profile , then all the notifications that you manage should disappear.
4. Find Previous Bundle ID or Application Domains from past Prompts
If you want to see previous prompts that you have already answered try this command.
sqlite3 "$(getconf DARWIN_USER_DIR)/com.apple.notificationcenter/db2/db" "select * from app;"
4. Manage Notifications with a Profile.
The easiest way to manage Notification is with a Configuration Profile.
NOTE: If you use Jamf Pro, Notifications is not an option yet in 10.15.1.
I will show you two ways to create a Notifications Profile.
Creating Profiles is easy with Profile Creator! The version that we will be using is v0.3.2 which has Catalina Options built right in. After installing you will see the welcome screen.
Profile Creator’s Welcome Screen.
You can start by filling out the General Settings. Set the Name of the profile, Description, Company Name and Payload Scope. For the Payload Scope select System if you want the settings to be for all users. You can add Prevent users from removing this profile (Supervised)
Profile Creator’s General Settings.
Once you have the General Settings set you can add a new profile payload. Scroll down on the left hand side until you see macOS. You will then see Notifications.
Profile Creator Notifications Payload.
To start you will need to add the Notifications Payload Key. Click the + button on the left hand side of Notification Settings.
Profile Creator’s Notifications Payload Settings.
Now that Notifications Settings is active you can add new keys. Click the + button to add a new Key.
Profile Creator’s Notifications Key
Now you can view the different settings you can set.
1. Enable Notifications
2. Bundle Identifier for the target app
3. Show app in Notifications Center
4. Show Notifications at the Lock Screen
5. Notification Sounds Allowed
6. Allow Badges
7. Alert Type – None, Banners, Alerts
8. Enable Critical – If the banner can pass through DND
The option that you will need to find is the Application Bundle Identifier. An example would be Microsoft Outlook. The Bundle ID for Outlook is com.microsoft.outlook. How do you find the Bundle ID ?
You can find many ways to find the Application Bundle ID. I will show you 3 different ways to do this. One of the best ways is to look directly at the application info.plist. Run the following all on one line. Let’s check to see what Safari’s Bundle ID is.
Now that you have the Bundle ID, plug it into the 2nd box in the key options.
Profile Creator’s Notifications Key Application Bundle ID
You can now add as many keys as you want!
Profile Creator’s Notifications 2nd Key Application Bundle ID
Once you have finished adding all the Bundle ID’s you are ready to Add this payload to the main Profile and save it. Click the Add Button in the upper right hand corner.
Profile Creator’s Notifications Add NotificationsSettings to the main Profile.
You should now see this in the upper left hand corner.
Profile ready to save!
Now click on the upload button on the right hand side of the + button to save your new profile.
Profile Creator’s Save Menu
This is the save menu. Check over the settings to verify everything is correct.
NOTE: Just as the note says at the bottom. If you use Jamf Pro you need to Sign the profile with your Apple Developer ID. If you use any other MDM you do not have to do this.
You will now have a file called 10.15 Notifications.mobileconfig
You can now upload it to your MDM Server.
After installing the profile you can go into system preferences > Profiles and view the new profile. It will look something like this.
Notifications Profile Settings.
You can then scroll down to verify all the macOS Catalina Application Notifications settings.
6. Notifications Profile with Manage App Notifications.bash
William Smith aka (talkingmoose) just wrote an amazing bash script that will generate a Notifications.mobileconfig
The only limiting part of this script is that you can only set one application per profile. William has mentioned that he might look into adding the ability to add multiple application notification settings into one profile. If you would like this, please send him this feedback!

A big Thank You goes out to the following MacAdmins.
@stevemasser – For finding the Notifications Preference plist Location.
@roberthammen & @emily for Confirming that current notifications will disappear immediately when the profile is installed.
@eholtam for finding the neat sqlite3 trick for showing previously answered notifications.
