Zip files are created with the Finder and are compatible with many OSes. Good for small files & small number of items. Disk Images are created in disk utility.
Safe boot refers to when the system is starting up - safe mode is when the system is actually running - and safe login is when the system starts up the user session.

1.) Create a plain text file w/ the 2.) Make the first line #!/bin/bash 3.) Change the permissions to allow execution
It monitors all incoming connections and requests. Connections are allowed on a per-application basis. Advanced options include signing options - stealth mode - and more.
The loginwindow process logs all users out and then tells the kernel to quit all remaining system processes.


13. What five network file services can you connect to from the Finder's Connect To Server dialog?

It records what file operations are in progress at any given moment. If a power failure or system crash occurs - it can verify the integrity by replaying the journal.


21. Why is the root of a user's home folder visible to others?
If a known master password is reset - existing accounts are not negatively affected. If the master is reset because it was lost - however - preexisting accounts cannot be reset by the new password until the old FileVault passwords are reset.
So they can navigate to the public or sites folder

50. How do kerberos and keychain system differ for managing authentication services?
They're stored at the root of every volume in a /.Spotlight-V100 folder. A fileVault user's database is stored in his vault in his home user. Mail is in ~/Library/Mail/Mail Envelope. Spotlight plugins can be in any library folder in a folder called S
Access is based on the local filesystem. They'll start in their home folder but can traverse anywhere they have permission to do so.
Kerberos can only be used to authenticate against kerberized services and is often managed on a network-wide scale.
This ignores any ownership rules and will grant any logged-on user unlimited access to the contents of the volume.
