Mac Os X Extended

Are you having trouble creating Mac OS Extended (Journaled) and APFS partitions using Disk Utility? If so, you can create a Mac OS Extended partition using GParted, then convert to APFS using Disk Utility.

Disk Utility

The Mac OS Extended Format, also known as HFS+, is the primary volume format for Mac OS X. Some of its features include: Because it uses a 32-bit address to store data, HFS+ can assign more than four billion allocation blocks to a volume. As a consequence, the minimum file size for even very large volumes remains small, usually around 4KB. Sometimes, advanced Mac users may review extended attributes for a file, or even wish to remove extended attributes from a file or directory for a variety of reasons, and either of those tasks can be accomplished through the command line with the bundled xattr tool in Mac OS. Widely used before Mac OS X, can be considered as a more elaborate extended attribute system, and may also hold main data of the file. Office mui msi download.

Disk Utility is a disk utility on macOS operating system. It supports creating, splitting, merging, resizing, deleting and formatting partitions on the hard disk. Disk Utility only supports partition creation and formatting for Mac OS Extended (Journaled), exFAT, MS-DOS (FAT) and since MacOS High Sierra (10.13), it supports APFS.

If you are a Linux user or operating systems other than macOS, you probably use another tool. In another case, if you are using a Seagate, WD My Passport or any other hard drive that you previously partitioned with another tool. Disk Utility will report MediaKit reports not enough space on device for requested operation. This error occurs because the partitions created do not comply with Apple's partition policy. In this case, you can use other tools instead of Disk Utility.

GParted

GParted is a well known disk partitioning program. It supports many partition formats such as FAT32, NTFS, exFAT, Ext4 and of course supports Mac OS Extended. We can use GParted to create Mac OS Extended partitions in just a few simple steps.

Mac Os X Extended Vs Apfs

GParted comes pre-installed on many Linux distributions like Ubuntu, Debian, Linux Mint… If you already have GParted installed, just use it. If not, you can download GParted or 4MParted ISO files then integrate into AIO Boot. You should use these two operating systems, as they have pre-installed programs that support the format. If you use GParted on Ubuntu, Linux Mint or Debian, you need to install hfsprogs.

The format of Mac OS Extended is HFS+. There are some commercial softwares that support creating HFS + partitions on Windows, but GParted is free. Now we will create the HFS+ partition with GParted.

  1. Run GParted and select the hard disk in the dropdown list at the top right. My hard disk is /dev/sda.
  2. You can only create new partitions if your hard disk has unallocated space. Right-click on the unallocated space and select New. You can also format existing partitions to HFS+. Right-click the existing partition, select Format to, and then select hfs+. Or delete the existing partition to recreate it.
  3. Select hfs+ in the File system. Then select and enter some information for the other items you want.
  4. Click Add, then click Apply to apply the changes.

The Mac OS Extended partition created by GParted will not be journaled. However, we can use Disk Utility to Enable Journaling. Or use the following command to format Mac OS Extended to Mac OS Extended (Journaled):

/dev/sdaX is the partition you want to format.

Convert to APFS

From the MacOS High Sierra version, Apple announced a new file system called APFS. By default, macOS High Sierra can only be installed on an APFS partition. You can use Disk Utility to convert Mac OS Extended partitions to APFS without losing data.

If the Mac OS Extended partition is not Journaled, please journaled it first. Run Disk Utility, select the Mac OS Extended partition in the left column, then select File and select Enable Journaling.

Now you can convert Mac OS Extended (Journaled) partitions to APFS without losing data. Just select Edit and select Convert to APFS… Mac multi os.

By using GParted with the simple steps above, we can easily create Mac OS Extended (Journaled) partitions and many other formats that Disk Utility does not support. If you need to create macOS High Sierra bootable USB from Windows, you can try Clover Boot Disk. Good luck!


The Mac OS Extended Format (HFS+) is a volume format compatible with Mac OS 8.1 and higher, including Mac OS X. In terms of volume, folder, and file size limits, it is similar to the Macintosh Standard Format (HFS).
HFS+ or HFS Plus is a file system developed by Apple Computer Inc. to replace their Hierarchical File System (HFS) as the primary file system used in Macintosh computers (or other systems running Mac OS). It is also one of the formats used by the iPod music player. HFS+ is also referred to as Mac OS Extended Volume Hard Drive Format, where its predecessor, HFS, is also referred to as Mac OS Standard.
HFS+ is an improved version of HFS, supporting much larger files (block addresses are 32-bit length instead of 16-bit) and using Unicode (instead of Mac OS Roman or any of several other character sets) for naming the items (files, folders) - names which are also character encoded in UTF-16 and normalized to a form very nearly the same as Unicode Normalization Form D (NFD) (which means that precomposed characters like é are decomposed in the HFS+ filename and therefore count as two characters and UTF-16 implies that characters from outside the Basic Multilingual Plane - often seldom used and characters from ancient writing systems - also count as two characters in an HFS+ filename). HFS Plus permits filenames up to 255 UTF-16 characters in length, and n-forked files similar to NTFS, though until recently, almost no software takes advantage of forks other than the data fork and resource fork. HFS+ also uses a full 32-bit allocation mapping table, rather than HFS's 16 bits. This was a serious limitation of HFS, meaning that no disk could support more than 65,536 allocation blocks under HFS. When disks were small, this was of little consequence, but as larger-capacity drives became available, it meant that the smallest amount of space that any file could occupy (a single allocation block) became excessively large, wasting significant amounts of space. For example, on a 1 GB disk, the allocation block size under HFS is 16 KB, so even a 1 byte file would take up 16 KB of disk space.

How do I know a hard disk is HFS+ format?

Select the hard disk in the Finder and choose the Get Info command in the File menu. The format information will specify either Mac OS Standard (hfs) or Mac OS Extended (hfs+).

Mac Os X Extended Format


What are the differences between HFS+ format and HFS format?

The most visible difference between HFS+ format and HFS format, other than the minimum file size, is the maximum number of files.

Mac Os Extended Journal

An HFS+ volume contains five special files:

  1. Catalog file - Describes the folder and file hierarchy of the volume. It is organized as a 'balanced tree' for fast and efficient searches
  2. Allocation file - Specifies whether an allocation block is free (similar to $Bitmap in NTFS). This is stored in a bitmap, specifying a free allocation block with a 'clear bit'
  3. Attributes file - Contains attribute information regarding files or folders
  4. Extents overflow file - Additional extents (contiguous allocation blocks allocated to forks) are stored in a b-tree in this file
  5. Startup file - Allows computers to boot that do have built in support for HFS+ file systems
