Installing macOS in Fedora (Gnome) Boxes

I need macOS to test apps for macOS. I'm running Fedora Workstation F41 (latest version while writing this). I already have a Ubuntu and a Windows VM in Gnome Boxes.

Setup

Tried to follow this guide: https://github.com/kholia/OSX-KVM Some steps in the guide could be skipped for me.

Clone the repository. Files from this repository are used in the following steps.

Proton VPN IPv6 Manual Setup

Update 2026-03-07: Proton has added the IPv6 configurations mentioned below to the WireGuard config files that you can get through the web dashboard. The guide below is for historical purposes only.

Over 80% of the servers support IPv6 but only the Linux & Android apps and the browser extension support it **at the moment**.
The Linux app supports IPv6 over the VPN but still connects to the VPN server using IPv4.

It's possible to make changes to the WireGuard configs that you can get from https://account.protonvpn.com/downloads to enable IPv6.

Web Key Directory for Proton Mail using Cloudflare Workers

Web Key Directory is a way for non-Proton users find your keys and encrypt the messages sent to you. Proton doesn't offer this for custom domains out-of-the-box, but you can proxy requests from your domain to Proton.

Create a Cloudflare Worker
Put this code in the Worker:

export default {
 async fetch(request, env, ctx) {

Globalping Probe as Quadlet

Quadlets are available since Podman 4.4, and offer an easy way to manage container and to keep them updated!

Check podman --version.
Create /etc/containers/systemd/globalping-probe.container with the content below:

# Equivalent to sudo podman run -d --cap-add=NET_RAW --network host --restart=always \
# --name globalping-probe globalping/globalping-probe

Fedora LVM Cache for Intel Optane

Did you know that LVM has built-in support for Intel Optane? Neither did I. It's a manual configuration though and it doesn't seem to be easy to do with BTRFS, so I simply went for EXT4. (Update: it's possible to put BTRFS on LUKS on LVM with the latest Anaconda.)

Why would you want to enable the Optane cache? It supports super low latency no matter how much you use it while the big NVMe SSD is going to get slower the busier it is.

Note: I'm talking about laptop NVMe SSDs with built-in Optane cache. Mine is a Intel® Optane™ Memory H10 32GB + Intel® QLC 3D NAND SSD 512GB, M.2 80mm PCIe 3.0, which came pre-installed in my HP Spectre x360.

To start:

Enter the UEFI and turn on ACHI for the SSD (I don't know if I did it as I forgot my UEFI password)

Mounting SSHFS (SFTP) using systemd

Why use fstab when there's systemd?
