- Many users will remember that hard drive 'journaling,' now standard on Panther installations, was originally introduced in OS X 10.2 (Jaguar) as a 'Mac OS X Server-only' feature; however, since.
- The partition on macOS could be APFS, MacOS Journaled, Encrypted MacOS Journaled or Case-Sensitive. With a working partition map, your USB will always show up in the Finder or Desktop.
- The disk drive in the system is formatted with a file system other than Mac OS Extended (Journaled) or it is formatted as Case-sensitive. AutoCAD installation on.

When you attach a storage disk to a Mac with the purpose of erasing or repartitioning it, you'll be presented with the option of selecting one of the three available partition maps: GUID Partition Map, Master Boot Record, and Apple Partition Map. In this article we will explain what a partition scheme is and which one to pick when formatting a drive.
What Is a Partition?
The fixed-sized subset of a disk drive treated as an individual unit by the operating system (in our case macOS) is defined as a partition. On every drive there are multiple partitions, and for this you will need a partition table or partition map – maintained by the operating system – to detail the status of the partitions.

Format your APFS drive back to MacOS Extended Journaled(HFS+), FAT or ExFAT - macOS Secret Trick 2019. A common problem people facing is inability to refor.
GUID Partition Map
This is a standard for the layout of the partition table on a storage disk using globally unique identifiers (GUIDs). As part of the Unified Extensible Firmware Interface (UEFI) standard, GUID is a bootable standard for systems with EFI firmware such as macOS. Non-Intel Macs won't support this bootable standard, hence the only option available to them is the Apple Partition Map (APM).
Apple Partition Map
Used on disks formatted for use with 68k and PowerPC Macs, the Apple Partition Map is the scheme that defines how the data is organized. Starting with OS X Tiger, both APM and GUID partitions can be used for accessing volumes, but PowerPC-based Macs can only boot from APM disks. While Intel-based Macs generally boot from a GUID Partition Table, they are all able to start the operating system from APM and Master Boot Record (MBR) using the BIOS-Emulation called EFI-CSM.
Master Boot Record
Introduced by IBM in 1983 to support the 10MB hard disk, the Master Boot Record is a type of boot sector developed for use with IBM PC systems. It is currently used for Windows partitions formatted as MS-DOS (FAT) or ExFAT.
Choosing a Partition Map
Now you know which partitioning map is which, the next time you insert an external drive or want to partition the built-in storage disk of the Mac, it will be easier to choose between the available options.
When formatting or erasing a volume with Disk Utility, you'll see a format menu prompt asking you to choose from:
- Mac OS Extended (Journaled)
- Mac OS Extended (Journaled, Encrypted)
- Mac OS Extended (Case-sensitive, Journaled)
- Mac OS Extended (Case-sensitive, Journaled, Encrypted)
- MS-DOS (FAT)
- ExFAT
- APFS (macOS High Sierra’s new file system)
- APFS (Encrypted)
- APFS (Case-sensitive)
- APFS (Case-sensitive, Encrypted).
Be aware that APFS is compatible only with macOS High Sierra and higher, so earlier versions of OS X or macOS won't mount an APFS volume. If you want maximum reach, Mac OS Extended (Journaled) is the right choice.
Below the file system format, the Disk Utility dialog box will list another contextual menu, the partition map scheme, which gives you another great tool to create targeted volumes. If you are looking to format a disk that will be shared with Windows users, the MBR scheme and MS-DOS (FAT) are the best choices. For drives used with Intel-based Macs only, the GUID Partition Map should the option to go for.
If you don't see the partition map scheme option, it is likely because Disk Utility doesn't list all volumes. This will prohibit Disk Utility from erasing the disk and show you an error message. To address this issue, you should click on the View button located in the top-left side of the Disk Utility dialog box and select “Show All Volumes”. From that point on, Disk Utility will ask for your partition map preference, and the formatting process will be smoother.

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.Mac Os Journaled Windows Reader
Disk Utility
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.
In this article, I will guide you to create a Mac OS Extended (Journaled) partition with GParted. If you want to install macOS High Sierra or later versions, just use the Convert to APFS feature on 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.
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.
Mac Os Extended Journaled Vs Apfs
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.
- Run GParted and select the hard disk in the dropdown list at the top right. My hard disk is /dev/sda.
- 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.
- Select hfs+ in the File system. Then select and enter some information for the other items you want.
- 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…
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!
