1. What process or processes are responsible for dashboard widgets?
It starts with a full copy of the system and then it records any changes made to the system and only copies those changes. It creates a simulation of the entire system using hard links for files that didn't change.
System Profiler
All users can read/write - but only the creator can delete. This uses the sticky bit.
The Dock process starts the DashboardClient process. All widgets run inside one of the two DashboardClient processes.


2. What steps should you take when troubleshooting app issues?
Applications - Library - System - Users
It stores the home folder as an encrypted sparse-bundle disk image
Restart the app - try another document - try another user account - check log files - delete caches - replace preferences - and replace app resources.
Single partition drives are easier to setup initially - but aren't as flexible for admin/maintenance. Multiple can segregate data


3. What are the four default top-level folders available in the Finder?
Applications - Library - System - Users
More options than GUI - bypass finder restrictions - root access - remote ssh is invisible to users - automation easy with scripting - easy combining with ARD
Users don't traditionally need access to them - and if they do - they can use Terminal.
It stores the home folder as an encrypted sparse-bundle disk image


4. Why is the root of a user's home folder visible to others?
So they can navigate to the public or sites folder

System launchd is responsible for starting every single system process. It manages system initialization and launches loginwindow.


9. Security risk with fast user switching?
Local accounts are just for that Mac - network accounts are available anywhere on the network - and Mobile accounts create a cached local copy of a network account for offline access.
All users can read/write - but only the creator can delete. This uses the sticky bit.
Locally connected volumes are fully accessible to any logged in user.

16. What does iSync do?
The client uses the subnet mask to decide if the client is on the LAN. If it's not on the LAN - then it sends the data to the IP address of the local router. Traffic continues through routers until it reaches the destination.
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.
iSync allows you to sync personal info between Mac OS X apps and peripherals like Palm PDAs - and Bluetooth enabled cell phones.
