Aggregate Audio Device settings will not save on restart fix OS X

Aggregate Audio Device settings will not save on restart fix in OSX :

If you have more than one user account, you must be logged in as an administrator to carry out these instructions.

Triple-click anywhere in the line below to select it:

sudo chown 202:202 /L*/P*/A*/*.audio.*.plist; sudo chmod -N $_

Copy the selected text to the Clipboard (command-C).

Launch the Terminal application.

Paste into the Terminal window (command-V). You’ll be prompted for your login password, which won’t be displayed when you type it. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning not to screw up. Confirm. You don’t need to post the warning. If you see a message that your username “is not in the sudoers file,” then you’re not logged in as an administrator.

Quit Terminal and reboot.

To test if it worked create an aggregate device in audio midi setup, restart your mac and check that your new device settings saved.

How to turn off Auto Renew for Apple Music trial period

Turn off auto-renew

To sign up for the free three-month trial of Apple Music, you need to use your Apple ID account with a valid credit card. That means that when those three months are over, Apple will start automatically charging $9.99 a month to your card for the service ($15 if you went with the family option). 

To avoid surprise charges, you can disable auto-pay now. To do that, open the Apple Music app on your iPhone, click the profile icon in the top left corner, and tap on “View Apple ID.” (You can also get here through the iOS Settings app: Go to Settings, iTunes & App Store, and click on your Apple ID). 

Enter your password, click on Payment Information, scroll down and click on “Manage” under Subscriptions. If you have multiple subscriptions, select the one for Apple Music and toggle the Automatic Renewal option to “off.”
