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

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.

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+.

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!
