What Is The File Type Necessary For You To View A Mac Disk Image In Windows Over A Network5/16/2019 A file with the DMG file extension is an Apple Disk Image file, or sometimes called a Mac OS X Disk Image file, which is basically a digital reconstruction of a physical disc. For this reason, a DMG is often the file format used to store compressed software installers instead of having to use a physical disc. For some silly reason that I have yet to discover, sometimes when you have a picture (graphic) on OSX, it will maintain it's mime type, but it won't have an extension. OSX will know what to do with it, but Windows won't - since the file has no extension. Make sure the file has an extension. Understanding File System Permissions The technologies collectively known as “file system permissions” are used to control file and folder authorization for Mac OS X. File system permissions work alongside the user account technologies, which control user identification and authentication, to provide the Mac’s secure multiuser environment. File system permissions—again just like user accounts—permeate every level of the operating system, so a thorough investigation of this system is required to fully understand Mac OS X. Create mac bootable usb from windows without transmac. In short, every single item on the system volume has permissions rules applied to it by the operating system. Only users and processes with root account access can ignore file system permissions rules. Thus, these rules are used to define file and folder access for every normal, administrative, guest, and sharing user. Any user can easily identify the permissions of a file or folder with the Finder’s Get Info window. NOTE The Mac OS X interface sometimes uses the word “privileges” in place of permissions. In general the meaning of these two terms is similar. Viewing File System Permissions To identify file system permissions from the Finder: • In the Finder, select the file or folder for which you wish to identify the permissions. You can select multiple items to open multiple Get Info windows. • Open the Get Info window. There are several methods for doing this. You can choose File > Get Info from the menu bar; use the Command-I keyboard combination; choose Get Info from the Action pop-up menu in a Finder window toolbar; or in the Finder, right-click or Control-click on an item and choose Get Info. • Once you have opened a Get Info window, click the Sharing & Permissions disclosure triangle to reveal the item’s permissions. Note that the permissions list is broken into two columns. To the left is a list of users or groups with access to this item, and to the right is the associated privilege assigned per user or group. Modifying these settings is covered in the “Managing Permissions” sections later in this chapter. TIP You can also identify ownership and permissions from the Finder’s dynamic Inspector window. This is a single floating window that will automatically refresh as you select different items in the Finder. The copy is in good shape and, so it the original, only one category changed for some reason.' Scanning takes a little longer than a minute and a half and the back up bar is 50% across after five minutes. Why does quicken for mac backup take so long. Why does it take so long to open Quicken? This didn't happen until a few months ago. Also after I reconcile I can't print the reconciliation and this is my only record of checks. I use Quicken 2001. When I click to open it just sits there with nothing happening for 10-15 minutes. To open the Inspector window from the Finder, use the Option-Command-I keyboard combination. Ownership for Permissions Every file and folder belongs to at least one owner and one group, and also has an ownership setting for everyone else. This three-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. For example, the user owns most of the items in his home folder. The system or root user almost always owns system software items, including system resources and applications. Traditionally, only the owner can change the item’s ownership or permissions. Despite this, Mac OS X makes management easier by giving every administrative user the ability to change ownership and permissions regardless of who the item’s owner is. • Group—By default, the group of an item is inherited from the folder it was created in. Thus, most items belong to the staff, wheel, or admin groups. Group ownership is designated to allow users other than the owner to have access to an item. For instance, even though root owns the /Applications folder, the group is set to admin so administrative users can make changes to the contents of this folder.

In other words, this means everyone else. 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 settings for a computer with many user accounts and shared files, as is the case with many servers. Fortunately, as you’ll see later, access control lists (ACLs) were developed to allow for nearly limitless ownership and permissions configurations. Traditional UNIX Permissions Mac OS X’s basic file system permissions structure is based on decades-old UNIX-style permissions. This system also sometimes goes by POSIX-style permissions. The system may be old, but for most Mac users it is quite adequate because you can define privilege rules separately at each ownership tier. In other words, the owner, the group, and everyone else has individually specified access to each file or folder.
