The primary function of the Multiagency Coordination System (MACS) is to coordinate activities above the field level (or incident level). In doing this, common functions of the MACS include:

  • Situation Assessment
  • Incident Priority Determination
  • Critical Resource Acquisition and Allocation
  • Policy Support
  • Coordination with other MACS Elements
  • Coordination with Elected, Appointed, and Senior Officials
  • Information Management and Common Operating Picture Maintenance

Mac OS, operating system (OS) developed by the American computer company Apple Inc. The OS was introduced in 1984 to run the company’s Macintosh line of personal computers (PCs). The Macintosh heralded the era of graphical user interface (GUI) systems, and it inspired Microsoft Corporation to develop its own GUI, the Windows OS.

The two most commonly used elements of MACS are Emergency Operations Centers (EOCs) and Multiagency Coordination (MAC) Groups. EOCs are the entity from which the coordination of information and resources to support incident management at the Incident Command Post (on-scene or field level activities) occurs. MAC Groups are policy setting entities typically comprised of agency administrators/executives, or their designees. Under the National Incident Management System (NIMS), neither an EOC nor a MAC Group has any direct incident command involvement and they will often be located some distance from the incident scene.

Contrary to popular belief, there is no requirement for EOCs to implement and organize around ICS. EOCs may be organized by:

  • Major discipline (e.g., fire, law enforcement, or emergency medical services);
  • Emergency support function (e.g., transportation, communications, public works and engineering, or resource support);
  • Jurisdiction (e.g., city, county, or region); or,
  • More likely, by some combination thereof.

Regardless, an EOC should be organized to facilitate effective incident coordination and support in accordance with applicable laws, policies, ordinances, statutes, etc., that govern incident management and coordination in the jurisdiction the EOC serves. It is this non-standard approach that makes it difficult to develop standard EOC training. For this reason, EMSI’s seasoned cadre stands ready to help tailor EOC training to the unique needs and organization of your specific EOC. Our experience has found that this training is best conducted in a facilitated workshop format.

Look to the right for an offering of MACS training but we recommend contacting us to talk about your EOC training needs.

In this article, we look at how to access the System folder and what you can modify within System Preferences, which is not hidden and contains valuable tools and ways to make changes within your Mac.

How to access the System folder

What Is The Mac System Font

Apple prefers to hide folders that could be at risk from viruses and cyber-attacks. Not only that but if an inexperienced Mac user were to make a mistake — or delete something important — native or downloaded (third-party) applications could stop working. Therefore, it is safer if certain folders, such as the Library and/or System folder, remain hidden.

However, there are times when you need to access these folders. Maybe an app is misbehaving, so one way to solve this problem is to “Delete the application's plist,” which is only possible with access to the System folder or Library. Within these folders, you benefit from complete control and can modify settings or clear out cache files.

Access the System folder using Terminal

However, if you would prefer doing this the manual way, here is how you can access the System folder:

  1. Launch Terminal; which you can find in /Applications/Utilities
  2. Enter this command in Terminal: chflags nohidden ~/System
  3. (If nothing shows up under that name, try /Library as an alternative)
  4. Click Return. Make sure the command is executed.
  5. Quit Terminal. The System folder should be visible in the Finder.
  6. If you ever want to restore this to how it was before, enter the following command in Terminal: chflags hidden ~/System
  7. Click Return again, and it should be back to how it was.

How to see Mac system files in Finder

Only attempt this method if you are comfortable using Terminal and have used it before. This method will make the folder permanently visible, so if you’d prefer it was only temporary, there is another way - for those using Mac OS X (or macOS) Mavericks and later.

  1. Open a Finder window and go to your Home folder.
  2. Within the Finder menu, click View > Show View Options.
  3. Place a checkmark next to Show System or Library Folder.

And that should give you quick temporary access to the System folder. However, you may need to do that again after accessing it as Apple prefers to keep this hidden.

Pro Tip: If you’ve previously used iPhoto — but are now using Photos on your Mac — you could have duplicate iPhoto libraries. You could be amazed at how much space you could save.

How to access System Preferences?

Now, if you aren't looking for complete control of the apps on your Mac, there is another way to modify how everything operates.

  1. Go to the Apple Menu.
  2. Find System Preferences. Or you can access this through Siri, Finder, or the Applications Folder.
  3. Within System Preferences, you can make a wide range of top-level system changes without needing to access anything hidden through Terminal or the Finder.

With this level of behind-the-scenes access, you can make improvements to the performance of your Mac. Delete apps that take up too much space. Customize how your macOS looks. If your Mac isn’t performing as well as you would like, gaining access to System and Library folders is one of the best ways to regain the speed and efficiency you once enjoyed.

Another way to unlock the hidden space is to download the tool I often recommend, CleanMyMac X. It has the so-called Space Lens feature that builds the interactive map of your storage. You will see lots of folders you rarely get to visit, like Movies, Application cache, etc.
Download the app's free edition here.
Now you can explore the space 'bubbles,' zoom on hidden files and folders, and delete them right on the spot. A good way to free up space when you need it. Here is the System Folder as viewed from the Space Lens:
