Shrinking VM drive

I am running macOS Sierra as a guest under Parallels Desktop 16 running in a Catalina host. I know the VM hard drive can be resized to give more space to the VM. However, is the any way to reduce the size of the VM hard drive? The 256GB currently allocated to the VM hard drive is far more than I need. Related to this, is there a way to safely remove pre-installed apps in the guest OS? Most of these are available in the host Catalina OS and are not needed in the guest.

 

Hello, please check this blog article and let us know if it's not that case.

 

No this does not work. When I try to configure the Hard Disk, if I uncheck the Expanding Disk tick box, everything is grayed out. I have no ability to reduce the virtual HDD below the minimum of 256GB. Disk Utility reports that I am using about 33GB on the volume macOS Sierra-0 SSD media and I do not anticipate needing much more than that. My use of the Sierra VM is limited to running Lightroom and PS. I can do everything else I need to on the Catalina host. Not being able to reduce the size of the HDD is very frustrating inasmuch as it strands about 150 or more GB of physical drive.

 

Thanks. I'll give this a try.

 

Worked as advertised. Appreciate the post.

 

thanks so much! it works well.

 

Hi Harald, thank you so much for your advice. I have some problems when booting from the new disk.
I deleted the old disk and create a new smaller one, which seems nice. But I cannot start windows on the new disk because I am not familiar with cloning things. Could you please give some details about the step three "clone your system"?

 

Deeply appreciate your reply.
