![]() Need Access Mac OS XHere's how to set up and use the connection. Step 4: Figure out which CAC (ID Card) you have (You need to know this information for step 6) Look at the top back of your ID card for these card types.The technologies collectively known as “file system permissions” are used to control file and folder authorization for MacIf you need to access Windows applications through your Mac, a remote desktop connection is the way to go. Then quit Word.Step 3a: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac' Step 3b: Look below Mac OS X for: Example: Version 10.X.X, or 11.X. Then select all modules listed under Normal.dotm and delete them.Any user can easily identify the permissions of aFile or folder with the Finder’s Get Info window.The Mac OS X interface sometimes uses the word “privileges” in place of permissions. Thus, these rules are used to define file andFolder access for every normal, administrative, guest, and sharing user. Only users andProcesses with root account access can ignore file system permissions rules. File system permissions—again just like user accounts—permeate every levelOf the operating system, so a thorough investigation of this system is required to fully understand Mac OS X.In short, every single item on the system volume has permissions rules applied to it by the operating system. File system permissions work alongside the user account technologies, which control user identification and authentication,To provide the Mac’s secure multiuser environment. ![]() ThisThree-tiered ownership structure provides the basis for file system permissions:Owner—By default, the owner of an item is the user who created or copied the item to the Mac. To open the Inspector window from the Finder,Use the Option-Command-I keyboard combination.Every file and folder belongs to at least one owner and one group, and also has an ownership setting for everyone else. This is a single floating windowThat will automatically refresh as you select different items in the Finder. Modifying these settings is covered in the “ManagingPermissions” sections later in this chapter.You can also identify ownership and permissions from the Finder’s dynamic Inspector window. Group ownership is designated to allow users other than the owner to have access to an item. Thus, most items belong to the staff, wheel,Or admin groups. Despite this, Mac OS X makesManagement easier by giving every administrative user the ability to change ownership and permissions regardless of who theGroup—By default, the group of an item is inherited from the folder it was created in. Traditionally, only the owner can change the item’s ownership or permissions. The system or root user almost always owns system software items, including system resourcesAnd applications. The system may be old, but for most Mac users it is quite adequate because you can definePrivilege rules separately at each ownership tier. This system also sometimesGoes by POSIX-style permissions. Fortunately, as you’ll see later,Access control lists (ACLs) were developed to allow for nearly limitless ownership and permissions configurations.Mac OS X’s basic file system permissions structure is based on decades-old UNIX-style permissions. This includes local, sharing, and guest users.The simple three-tiered ownership structure presented here has been part of traditional UNIX operating systems for decades.However, with only three levels of permissions to choose from, it is quite difficult to define appropriate access settingsFor a computer with many user accounts and shared files, as is the case with many servers. In otherWords, this means everyone else. Pc mac co op games for couplesFinally, it’s important to note that if an ACL ruleApplies to a user or group, this rule will trump traditional UNIX permissions. Further, this implementationSupports an unlimited number of ACL attributes for any user or group. This ACL implementation is extremely flexibleBut increases complexity by adding more than a dozen unique privilege and inheritance attribute types. Though there is no common standard for ACLs, Mac OS X has adopted a style of ACL similar to thatAvailable on Windows-based NTFS file systems and UNIX systems that support NFSv4. However, Apple has streamlined the Finder to allow only the most common permissions options.Permissions that you can assign to a file using the Finder are:Read and Write—The user or group members can open the file and save changes.Read Only—The user or group members can open the file but cannot save any changes.No Access—The user or group members have no access to the file at all.Permissions that you can assign to a folder using the Finder are:Read and Write—The user or group members can browse and make changes to the contents of the folder.Read Only—The user or group members can browse the contents of the folder but cannot make changes to the contents of the folder.Write Only (Drop Box)—The user or group members cannot browse the folder but can copy or move items into it.No Access—The user or group members have no access to the contents of the folder.Access control lists (ACLs) were developed to expand the traditional UNIX-style permissions architecture to allow more controlOf file and folder access. Further, because of the inherent hierarchy built into the file system, where folders can reside inside of other folders, you easily create a complex file structureThat allows for varying levels of sharing and security.There is a variety of UNIX privilege combinations available from the command line, as discussed in the “Managing Permissions via Command Line” section later in this chapter. This single floating window, which automatically refreshes as you select different itemsIn the Finder, allows you to quickly explore the default permissions settings without having to open multiple Finder Get InfoWindows. Further, to aid in your exploration of the file system you shouldUse the Finder’s Inspector window. Permissions for SharingOnce you have an understanding of the permissions options available to you in Mac OS X, you should explore how the local fileSystem is set up by default to provide a secure environment that still allows for users to share files.If you don’t have fast user switching enabled as outlined in Chapter 2, “User Accounts,” you should enable it now to makeIt easy to test file system permissions as different users. In otherWords, the Finder uses the ACL architecture to let you configure unique privileges for an unlimited number of users or groups.Prior to Mac OS X v10.5, the Finder would only allow you to assign permissions using the standard three-tiered ownership style,With one owner, one group, and one setting for everyone else.The locked attribute is covered in the “Managing Locked Items via Finder” section later in this chapter. The only feature ofACLs that the Finder actually implements is the ability to have an unlimited number of user or group privilege rules. In fact, the Finder only allows you to assign ACL attributesThat match the most common UNIX permissions configurations that were previously listed in this chapter. Yet the Finder’s Inspector window is not showing you the full permissions pictureHere. Normally this permissions setting would also allow any user toDelete another user’s item in this folder. You’ll notice that this is a general sharing locationThat allows all users to read and write items to the folder. Sharing files is covered in Chapter 8, “Network Services.”An additional folder set aside for sharing is the /User/Shared folder. InspectingAnd changing permissions from the command line is covered in the “Managing Permissions via Command Line” section later in this chapter, and the sticky bit is specifically covered in the “Using the Sticky Bit” section later in this chapter. This permission setting, known as the “sticky bit,” can only be set using a command-line tool.
