NAS-first iSCSI
Built for typical Mac+NAS setups with Synology, QNAP, TrueNAS and compatible targets.
BLOCK STORAGE / macOS
Mount your Synology, QNAP or TrueNAS LUNs right on your Mac. SCSI DriverKit. A real block device in macOS.
For Intel and Apple Silicon. To join the beta test, go to the home page.
Interactive demo of the Home Edition with fictional NAS devices and volumes.
THE CRITICAL DIFFERENCE
A filesystem mount is not a LUN in the macOS SCSI stack. See why we chose the real SCSIControllerDriverKit path.
Production entitlement from Apple for our initiator. Shipped as a signed, notarized System Extension. And the app shows you at any time exactly what state the driver is in. On Apple Silicon with macOS 15 (Sequoia) and later, on Intel with macOS 13 (Ventura) to 26 (Tahoe).
This is in the beta and therefore in the Home Edition. Click for details.
Built for typical Mac+NAS setups with Synology, QNAP, TrueNAS and compatible targets.
Find targets, probe them and save them as persistent profiles.
Target connections over IPv4 and IPv6. LAN Discovery finds iSCSI devices on your local network.
Authentication in both directions with visible auth status.
Trusted, probation or quarantined. Always with reasons instead of gut feeling.
The Home view shows activity and status of your connections and disks.
Every LUN appears in macOS as a SCSI disk through the DEXT.
Format LUNs with APFS and mount them. Automount mounts volumes automatically.
Multiple targets and multiple LUNs per target in one app.
A Mac writing to a LUN announces itself via Bonjour. Other Macs see the writer.
Connection, driver and disk state in one place.
Time Machine backs up your Mac directly to an iSCSI LUN on your NAS without an extra profile.
Reach your target over IPv6 from anywhere once you enable access. Your NAS needs IPv6 and access allowed in your router and firewall.
When mounting, iSCSI4NAS hides the EFI partition in Finder. Finder stays tidy, even with several targets.
iSCSI4NAS is built for the most popular SOHO and home NAS systems and works with any standards-compliant iSCSI target.
Compatibility depends on target, firmware and NAS configuration. Your NAS missing from the list? That's exactly what the beta is for.
Two Home editions on the Mac App Store. Pro, Pro Business and Enterprise are planned for Apple Silicon.
Apple Silicon with macOS 15 Sequoia and later, for private use on the Mac App Store
after the beta, free during the beta
30-day free trial
Intel with macOS 13 Ventura to 26 Tahoe, for private use on the Mac App Store
after the beta, free during the beta
30-day free trial
Planned for Apple Silicon
Full feature set outside the App Store sandbox, for private use
Like Pro, for commercial use
For organizations and universities with central management and MDM
The data on your NAS stays there and is reachable with any standards-compliant iSCSI initiator. All editions apply to iSCSI4NAS on macOS. All prices include VAT. The Mac App Store shows the final price for your country.

We know everyone is tired of subscriptions, us too. We would love to offer iSCSI4NAS the classic way, as "buy once, use forever".
But iSCSI4NAS sits deep inside macOS and Apple changes the rules with almost every major update. On top of that comes the legal duty to keep the software secure and compatible for years. A one-time purchase just isn't viable for us, technically or economically.
And the yearly model actually has a real advantage for you: you don't have to worry about anything. Updates arrive through the Mac App Store. Install, done. No update stress, no hidden support costs, nothing. For us, that is exactly consumer protection.
For Intel the subscription is even the fairer choice: you only pay while you use your Intel Mac. When you move to Apple Silicon, simply cancel.
Building crash report frameworks, ad frameworks or user tracking into software like this is an extra business for software makers. We know ourselves that such kits often earn more money than the software itself. And that is exactly why we give you this guarantee:
We will never build such frameworks for tracking or ads into our products, no matter how much money it would bring, under no circumstances. Extremely sensitive data travels over iSCSI and for exactly that reason we will never allow it, let alone answer for it.
You can hold us to that.
This means we are counting on you: we deliberately give up the revenue others use to pay for their marketing. We bet on the one thing nobody can buy, your recommendation. So if iSCSI4NAS convinces you, spread the word.
You get the chance to test the Aviontex iSCSI initiator for macOS (iscsi4nas) before its official release.
This beta is for experienced users. There is no manual during the beta. It is written once the features are frozen at the end of Beta 3. If you need step-by-step instructions to discover, mount and unmount an iSCSI target, please wait for the release.
Sign up on the home page.
Use the software under real conditions, with different NAS systems, networks and macOS versions.
Every bug, every unexpected behavior, every crash counts. Report it in as much detail as possible.
What's next and when does it start? More details will follow in your personal invitation to the official beta test, until then we ask for a little patience.
Manufacturers are welcome to join the beta test as well.

The structural shakedown: mount and unmount, does the GUI fit, are the functions logical and well organized, does anything need to move, what's missing, how do the look and the handling feel. Bring in your ideas, this is where the shape gets decided.
Important: hands off production systems with the iscsi4nas iSCSI initiator during the Beta 1 phase. Your own LUN, your own target, ideally a dedicated NAS for it.
Now the functions from the full test catalog get hammered. Critical eyes, hard tests. Still the stuntman phase: no move without a safety net.
Now it gets interesting. The bugs are out and fixed, the features are final: this is the sign-off, does it fit or not. Fine-tuning and here the initiator gets to fly solo for the first time. Only once Beta 3 signs off do we start writing the manual.
Release candidate: flush out whatever bugs are still hiding.
Confirm and control: does everything fit from end to end?
One more pass, the final check.
When you've wrapped everything up and only when we are all happy, we let the initiator run free.
