Manage disk space on Macs with Boot Camp

  • Redistribute storage space between Mac and Windows anytime
  • Safe, easy and compatible with the latest macOS versions, including 10.13 High Sierra
  • Support technologies such as Fusion Drive, System Integrity Protection and the new Apple File System

The proven solution to manage disk space on dual system Mac

CampTune makes your Boot Camp Windows partition freely resizable. You may need to adjust the size of your Windows partition when, for example, you run out of disk space or want to install an application with particularly high storage requirements. CampTune provides a simple slider to redistribute storage space between Macintosh HD and Boot Camp Windows partitions. The resize operation is safe, fast and easy.

How it works

To redistribute storage space between macOS and Windows with Paragon CampTune, simply move the partition size slider and click Resize. Alternatively, type in the exact size in gigabytes for either partition.

Note that any changes to system disk partitions can only be made in a special boot environment called macOS Recovery mode. This is because the system disk configuration is a critical area of macOS guarded by the System Integrity Protection technology. CampTune guides you through the creation of a special bootable drive which is then used to start your Mac and safely resize the partitions. It will take a few minutes to create the required bootable media files; you will need a 1 GB or larger removable storage device like a USB stick or an SD card.

Frequently Asked Questions

What operations can I perform with the demo version?
The demo version only allows resizing operation of up to 2 GB. To remove this limitation, purchase a license key and activate the software.
Does CampTune work with System Integrity Protection (SIP)?
Yes, it does. Starting from the November 2017 update Paragon CampTune can perform resize operations with a system disk in macOS even with System Integrity Protection turned on.
Why does CampTune produce the “Invalid Boot Camp configuration” error?
Briefly, it means that your configuration now has a GPT/MBR mismatch. Please refer to this support Knowledge Base article for more information about the error and the way to fix it.
Is APFS supported?
Paragon CampTune fully supports the new Apple File System (APFS) which is a part of the new High Sierra version of macOS.
What if my version of Mac OS X is 10.10 or earlier?
If you use an old version of Mac OS X on your Mac, you can obtain a compatible version of CampTune by contacting Paragon technical support.

  • CampTune is a great software, especially for the low price of $19.95. If you work with Boot Camp, or are planning to do so, we highly recommend getting CampTune. As you will most likely need it at some point.

  • In the past, to reallocate free space on your Mac, you’d need to back up the Boot Camp partition, delete the partition, recreate an NTFS partition with a new size and, finally, restore the Windows partition backup to the new NTFS partition. This process could take anywhere between two and five hours. Fortunately, Paragon Software has developed CampTune, which achieves the same result in a matter of minutes!
