Choose your edition
Bitten Fruit comes in two base editions, Debian and Arch. Both include two boot variants: GRUB and rEFInd. rEFInd is the closest to the Mac experience and the most comfortable to use.
Stable Core
Debian Edition
A rock-solid, simple base.
Perfect for older computers or anyone who values stability above everything else. Ships with GRUB and rEFInd, the rEFInd variant is much more Mac-like and comfortable.
- GRUB (BIOS devices)
- rEFInd (UEFI devices)
Rolling Core
Arch Edition
Always up to date.
The newest drivers and packages. The choice for modern hardware. Ships with GRUB and rEFInd, the rEFInd variant is much more Mac-like and comfortable.
- GRUB (BIOS devices)
- rEFInd (UEFI devices)
Which boot variant do I need?
The GRUB editions only work on BIOS computers. If your computer uses UEFI, use the rEFInd version.
What is a 64-bit (AMD64) processor?
It is the type of processor almost every PC has used for the last 15 years. “AMD64” is the name of the 64-bit design, and it works with both AMD and Intel processors. If your computer runs Windows 8 or newer, it almost certainly qualifies.
What is BIOS?
BIOS is the older way computers start up, common in machines from before 2012. It shows a plain, text-only menu when the computer turns on. If your PC has BIOS, download the GRUB edition.
What is UEFI?
UEFI is the modern replacement for BIOS. Every computer sold in the last decade uses it. It starts the system with a friendly, graphical menu — with rEFInd, it feels closest to a Mac. If your PC has UEFI, download the rEFInd edition.
How do I tell them apart?
Simple rule: if your computer came with Windows 8, 10 or 11, it is UEFI → choose rEFInd. Only much older PCs (Windows 7 or earlier, roughly pre-2012) use BIOS → choose GRUB. Not sure? Ask the compatibility helper below.
Will it work on your PC?
Type your PC model and we will ask Google AI whether it can run Pulsar OS, and which edition to download.
Opens a Google AI Mode search with your model, Pulsar OS requirements, and which edition fits.
What you need
- A 64-bit (AMD64) processor
- 4 GB of RAM
- 20 GB of free disk space
- A 8 GB USB stick. Nothing more.
That is all. And the best way to find out how it feels? Try it on your own PC — you can run Pulsar OS live from the USB stick, without installing anything and without changing what is already on your computer.
Putting Pulsar OS on the USB
On Windows, use Rufus — and when it asks, choose DD mode. On Linux, use GNOME Disks (“Restore Disk Image”). We recommend not using Etcher, and not using Ventoy (still experimental with these ISOs).
Ready to download Pulsar OS?
All editions and boot variants are available on our downloads page. Grab the ISO that matches your PC and try Pulsar OS live from the USB stick.
You'll never break it.
Like a Mac, Pulsar OS ships with a hidden recovery partition. But we went further: however bad the disaster is, there is always a way back. The further down you go, the worse it gets — and every step still recovers.
Time Machine
Best caseYour system is backed up against a disk, a USB drive, a NAS or any of 55 cloud providers. Restore everything in one click. Nothing even feels broken.
Internet Recovery
Level 2The system won't start? Enter on the Recovery and Internet Recovery downloads a fresh recovery environment from our servers, Apple-style.
USB Recovery
Level 3No network? Connect a USB to the live environment that contains a squashfs and restore from it
The Live ISO
Worst caseWiped the bootloader AND the recovery partition? The very ISO you downloaded to install Pulsar OS contains a full recovery environment. Boot it and repair, reset or roll back. You are never locked out.
Panic is not part of the workflow.
And with Time Machine — which works beautifully against a disk, a USB stick, a NAS or 55 cloud providers — your data was never in danger in the first place.

Frequently Asked Questions
Everything you need to know about PulsarOS Bitten Fruit edition.
What makes Pulsar OS different from other Linux distributions?
Normal Linux distributions give you only a base and a graphical environment, but many do not even add functionality and very few innovate. Pulsar OS focuses on replicating the look and, very importantly, workflow of the operating systems that people use to offer the good of Linux with the good of, in this case, macOS.
Can I install it on my Macbook?
Of course you can on those Macbooks that have an Intel chip (those manufactured before 2020). We are working on a new release that includes all the drivers so that everything on your Mac works perfectly.
Can I run macOS, Windows, and Android applications?
Yes, of course, we include all the necessary applications for this.
Does it have an App Store?
Yes, we include a convenient program that allows you to install applications in multiple formats, without touching code. We also include the Pulsar Store, which allows you to install applications developed by people who love Pulsar OS, which have been reviewed by artificial intelligence.
