Best Mac Partition Manager Software

mac partition manager

Although Disk Utility is the default disk manager app built into macOS, it has limited functions when it comes to advanced partitioning. For example, it won’t work when you want to resize Boot Camp partition to arrange free disk space, or when you need to partition an external hard drive only to find the option is grayed out.

We’d like to share with you some Mac partition managers that are better than Disk Utility, so you can deal with customized partitioning needs for both Macintosh HD (or Boot Camp) and any external hard drives. At the end of the day, your Mac hard drive will be more organized and efficient.

Why Use Third-Party Mac Partition Software?

Having extra space in your Mac drive allows you to store more precious photos and videos, and your Mac is likely to run faster with a decent amount of free disk space. However these days your hard drive can be used up faster than ever, especially if you back up your iPhone or iPad data to your Mac. Also, those media files are much larger in file size and need more space to store.

If your primary boot partition, either Macintosh HD or Boot Camp, is getting full, macOS (or Windows in Boot Camp) is going to run a bit sluggishly. The best solution is to rearrange space between volumes by resizing either Macintosh HD or Boot Camp. In this case, you need an advanced third-party Mac partition manager, as Disk Utility won’t cut it.

Other times, you may want to make several partitions or adjust the size on an external hard disk, you could try Disk Utility, but sometimes you’ll find the partition option has been grayed out, or it takes forever to complete during the erasing process. A third-party partition software will save you time and effort.

Best Mac Partition Manager Apps in 2020: What to Consider?

Security: the apps must be 100% virus-free and malware-free. Also, it must not contain any other bundled or embedded plugins that inject ads while you surf the Internet. These days adware has been notorious among many Mac applications.

Features: the best Mac partitioning app should do what Disk Utility can’t. Otherwise, there’s no point wasting time downloading a third-party app. It would be great if the app can resize Boot Camp partitions if your Mac has a dual operating system (macOS + Windows), so it should work with both NTFS and HFS volumes, create bootable media which can be used to perform partitioning on boot drives, and/or other standard features like create/delete/format any partition easily.

Compatibility: it must be compatible with all common macOS versions, including the latest macOS Catalina.

Ease of use: the software should be relatively easy to operate, quick in the partition resizing/deleting process.

Technical Support: dealing with hard drive operations often need extra technical skills. Any misoperation could cause unexpected data loss. Therefore, the provider/developer of the Mac partition software should respond to user requests.

  1. I have a non bootable external USB hardrive that I wish to use to create a bootable cloned image of my MAC High Sierra OS.

    Will Stellar Partition Manager or Paragon Camptune X modify this USB drive to a bootable external drive?
