Resolving macOS Kernel panic issues with Vagrant and Parallels

Introduction

I am running an Apple MacBook Pro with an Apple M1 Max chipset. The Apple Silicon chipsets use arm64 architecture, but when I first started using Vagrant with the Parallels provider on my M1 Max, Parallels didn't yet support shared/synced folders on the arm64 architecture, so I was using NFS for my synced folders in my Vagrant development environment.

This worked perfectly until Apple released macOS Sequoia 15.4, and then suddenly the synced folders across NFS constantly caused macOS kernel panics resulting my laptop crashing.

Debugging the issue

I was hopeful with every macOS Sequoia 15.4.x point release that the issue would be resolved, but unfortunately the issue persisted with every macOS Sequoia 15.4.x point release, and also in macOS Sequoia 15.5.

When I inspected the crash files that were generated for sending to Apple, it appeared as though there may have been issues with my NFS for Mac application, so I uninstalled it, removed all of its kernel extensions, and rebooted my laptop but unfortunately the issue persisted.

I then finally realised that the issue was caused by using NFS for my Parallels synced folders, and discovered that the latest versions of Parallels now support shared folders on arm64 architecture.

Resolving the issue

Changing all of my synced_folder configuration in my Vagrantfile from type: "nfs" to type: "parallels" finally resolved the issue, and I have not experienced a single macOS kernel panic since.
