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.
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):
