But in High Sierra, Apple has changed the file system from HFS+ to APFS. Because of that, my old guide doesn’t work. So here is how to remove the Purgeable part of the disk in. Read this before continuing: Only use this for making more room if you need to change the partition size of your disk.
MacOS High Sierra Patcher Tool for Unsupported Macs. Open the 'macOS High Sierra Patcher' tool, and browse for your copy of the macOS High Sierra Installer App. Select the disk or partition you want to install on, and erase it, ensuring to use either Mac OS Extended (Journaled), or APFS as the filesystem type. If formatting an entire.
Usually for installing or having multiple partitions on a drive. If you don’t understand the above, don’t do it! The method is not a way of getting more space. That is all handled by the operating system. APFS – How a Smart File System Can Make Some Things Difficult Because Apple has changed to a much smarter file system, my old method of creating a file and then duplicate that file until the disk was full, thus forcing Mac OS to start to remove the Purgeable portion of the drive doesn’t work anymore. That’s because is smart enough to recognize that it’s the same file, so it makes pointers to the original data, so it doesn’t take up extra space. So here’s how to do it in Mac OS High Sierra.
Let’s Fill Up The Disk To The Brim To Remove Purgeable Open the Terminal application in Applications/Utilities. What we need to do is to start making a file that will grow until the disk is full. So enter the following into the Terminal window. Dd if= /dev /zero of= /stupidfile.crap The command will create a file called stupidfile.crap in your Home directory and fill it with zeros. It will continue to grow, first at a fast pace, but as the disk get’s close too full, it will become slower and slower.
But hang in there. During the creation of the file, you will get a lot of warning messages that the disk is full.
Just leave it there, because if you close it, it will reappear after a while. The Disk Is Full, Let’s Continue. When the Terminal window command ends with the message “No space left on device,” the disk is full, and mission accomplished. Mac OS should now have removed all the Purgeable space from the drive. So all that is left is to delete the file stupidfile.crap inside your home directory.
Don’t forget to empty the trashcan to regain the space. You should now have no Purgeable part of the partition left. Hello, I have been having issues installing windows using bootcamp. Its says “your bootable usb drive could not be created, there is not enough space available on the disk” I have tried all command including sudo tmutil thinlocalsnapshots / 99 dd if=/dev/zero of=/stupidfile.crap rm /stupidfile.crap And also unticked time machine, It still brings the same thing when i try to install again. On my storage I have 716 GB available. Please Is there any another solution or fix to this issue???????? Thank you for this.
I have spent 6+ hrs today trying to seek the solution. I ended up with 200GB of purgeable disk space and only 39GB free.
Every time I deleted any files it just became purgeable. I only want to go for a run, so issue started when my watch App didn’t have Apple Music App installed properly, however when I tried to backup my iPhone in order to do a new install, my Mac just returned not enough disk space. I have watched the stupidfile.crap fill up my HD to the tune of 200GB and once finished, deleted and I am now 200GB richer in free space!
