From Windows or macOS
What carries over, what changes, and what doesn’t come with you.
Will it run on your computer?
| You have | Pulsar? |
|---|---|
| A Windows PC with Intel or AMD graphics | Yes. The standard download. |
| A Windows PC with an NVIDIA GeForce RTX card |
Yes. The NVIDIA download (nvidia-open: RTX 20, GTX 16 and
newer). Older GeForce cards: use the standard download.
|
| A Mac with Apple silicon (M1 and later) | No. Pulsar is x86_64 only. |
| An Intel Mac, 2018 to 2020 | No. The T2 chip’s keyboard, trackpad and audio need drivers Fedora’s kernel lacks. |
| An older Intel Mac | Maybe. Untested. Broadcom Wi-Fi needs a driver the image lacks; keep a wired connection handy. |
Which graphics? Windows: Task Manager → Performance lists each GPU.
Before you start
Back up everything you want to keep to an external drive or a cloud. The installer erases only what you tell it to.
-
BitLocker (Windows). Save the recovery key (Microsoft account or Control
Panel) before changing firmware settings: a boot-order or Secure Boot change can make Windows
ask for it. The first command below (PowerShell, admin) prints
Protection Onif it’s enabled. - FileVault (Mac). Only macOS can read your files. Copy them off first.
- Licenses and passwords. Deactivate anything that counts devices (Adobe, Office, some games). Export or sync your browser’s passwords.
manage-bde -status C: # is BitLocker on?
manage-bde -protectors -get C: # the recovery key: write down the 48 digits
Make the USB stick
A USB stick of 8 GB or more (it will be erased) and the ISO from Get Pulsar.
From Windows or macOS: Fedora Media Writer
Install Fedora Media Writer from fedoraproject.org, choose Select .iso file, pick the Pulsar ISO and the stick, and write.
Rufus, balenaEtcher and friends
They work. In Rufus, pick DD mode. Ventoy works with the current ISO; read the warning about old downloads first.
To verify the download, see Install.
Start from the stick
-
A PC: restart with the stick in and tap the boot menu key (usually
,F12 ,F11 orF8 ). Pick the USB entry.Esc -
An Intel Mac: hold
at startup and pick EFI Boot.Option
Leave Secure Boot on. The NVIDIA image needs its key enrolled once after installing: steps.
The installer asks which disk and layout and changes nothing until you confirm. On a laptop, turn on disk encryption at the disk step.
Clock in the wrong time zone?
Keeping Windows
Keep Windows on the same disk and choose at power-on:
- Make room. Disk Management → right-click C: → Shrink Volume. 100 GB or more for games. Leave it unallocated.
- Turn off Fast Startup (Control Panel → Power Options → Choose what the power buttons do), or the Windows drive stays locked.
- Have the BitLocker key from Before you start.
- In the installer, pick the free space. Leave the Windows partitions alone.
If Windows isn’t in Pulsar’s boot menu, the PC’s boot menu lists Windows Boot Manager. Files can open the Windows drive if Windows was shut down fully.
Clock off by your time zone after switching? Windows keeps the hardware clock in local time. Make Pulsar do the same:
timedatectl set-local-rtc 1 --adjust-system-clock
Where things moved
| Windows | macOS | Pulsar |
|---|---|---|
| Start menu | Spotlight, Launchpad | Press Super and type. Super+A shows every app. |
| Taskbar | Dock | The dash, in the overview. Right-click an app there to pin it. |
| Settings, Control Panel | System Settings | Settings, in the app grid, or Super and type what you want. |
| Microsoft Store, a .exe | App Store, a .dmg | GNOME Software, or flatpak install. Both install Flatpaks. |
| Windows Update | Software Update | Downloads in the background; a notification offers a restart. Never restarts on its own. |
| File Explorer | Finder | Files. Your folders are under /home/you, called ~ for short. |
| Task Manager | Activity Monitor | System Monitor, in the app grid. |
| Terminal, PowerShell | Terminal | Ptyxis. Themed along with everything else. |
| System Restore | Time Machine (the system half) | Rollback: the previous build is in the boot menu. Your files are yours to back up. |
Window buttons are at the top right. To move them left: GNOME Tweaks → Windows → Titlebar Buttons → Placement. Tap-to-click and two-finger scrolling are on.
There is no C:\. Your files are in your home folder; the system is a read-only
image, so updates can’t touch your documents and can be undone.
Where things go.
Installing apps
Apps are Flatpaks from Flathub. Install them in GNOME Software, or in the terminal:
$ flatpak search libreoffice
LibreOffice The LibreOffice productivity suite org.libreoffice.LibreOffice stable fedora,flathub
$ flatpak install --user flathub org.libreoffice.LibreOffice
Firefox is built in. The first boot with a network installs a starting set (text editor, calculator, image, PDF, video and music viewers, Steam, Heroic, Discord, OBS Studio and more). Removed apps stay removed.
Apps you might be looking for
All on Flathub; search the name in Software.
| You used | Here |
|---|---|
| Office documents | LibreOffice, ONLYOFFICE |
| Photoshop, Paint | GIMP, Krita, Pinta |
| Illustrator | Inkscape |
| Lightroom | darktable |
| Premiere, iMovie | Kdenlive |
| Outlook, Mail | Thunderbird |
| VLC, a video you double-clicked | Showtime (installed), VLC |
| Chrome, Brave | The same apps |
| Spotify, Slack, Zoom, Signal | The same apps |
| A password manager | Bitwarden |
That one Windows program
Bottles (installed) runs many Windows programs through Wine. Utilities and older software often work; suites with activation (Microsoft Office, Adobe Creative Cloud) mostly don’t, so use their web versions. Mac-only apps can’t run.
Updates
The system updates as one image. It downloads in the background on AC power, and a notification (Pulsar 44.x is ready, with a Restart button) says when it’s ready. It takes over at your next restart; nothing restarts on its own.
sudo pulsar update # the system, from your next restart
flatpak update # your apps, or use Software
$ pulsar update --check
up to date: 44.20260928.0 (ghcr.io/arclight-digital/pulsar-nvidia:latest)
$ pulsar status
STATE VERSION IMAGE PINNED
booted 44.20260928.0 ghcr.io/arclight-digital/pulsar-nvidia:latest no
- 44.20260927.0 ghcr.io/arclight-digital/pulsar-nvidia:latest no
The second line in pulsar status is the previous build: if an update misbehaves,
pick it in the boot menu. Rollback covers the system, not your files.
Updates and rollback.

From a Mac: copy and paste are
Games
Steam is installed; most Windows games run through Proton. Heroic covers Epic, GOG and Amazon. Gaming.
Anti-cheat: games whose anti-cheat blocks Linux won’t run (currently Valorant, League of Legends, Fortnite, recent Call of Duty). Easy Anti-Cheat and BattlEye games work only if the developer enabled Proton support. Check ProtonDB before wiping anything, or keep Windows.
What won’t work here
- Microsoft Office and Adobe apps as desktop programs. Their web versions work in the browser.
- Games with Linux-hostile anti-cheat, above.
- Apple’s services. No Linux clients for iCloud Drive, iMessage or AirDrop. iCloud’s website works.
- Windows-only hardware tools (RGB, fan, peripheral apps). The hardware usually works.
- Apple silicon Macs, at all.
For anything else, search GNOME Software first.
When you’re stuck
Open the terminal (Super, type terminal) and run:
pulsar doctor
Each check prints ok, warn or FAIL; warnings say what to do.
