Users of the popular high-end music management system Roon need to pay attention starting April 27th, 2026 (Please note that roonlabs in the first place announced this update for April 20th, 2026). Some owners will react with anger and despair when, after the update announced for that day, their server will no longer run. Roon’s so-called Core software will simply fail to start on some platforms.
The reason for this are new minimum requirements for the server operating system, starting with Roon software version Build 1643 or higher. What initially sounds like a technical detail will have far-reaching consequences for some server owners in practice.
Specifically, the change affects the underlying software architecture of the operating system (for IT experts: the switch to .NET 10), meaning numerous existing setups will no longer be supported in the future. The biggest concern is likely among owners of older Macs, QNAP NAS, and proprietary high-end music servers (such as Grimm, Silent Angel, Innuos, Melco, Mytek, Antipodes, Primecore, and many more). Our guide clarifies how to identify which systems will be affected, who doesn’t need to worry, and what to do to continue using Roon.
How does the problem manifest?
After the Roon Server version update, announced for April 27th, 2026, to B1645 or higher, the Roon Server software (formerly called Roon Core) will simply no longer start on incompatible systems. Smartphones and tablets with the Roon Remote control will no longer find a server on the network, no music can be played, and settings cannot be accessed.
There will also be no easy way to revert to the older version! You will be forced to manually reinstall Roon or switch to a different operating system. This often requires computer knowledge.
We therefore recommend two immediate actions:
- Check if your system will be affected
- If yes, or possibly: Deactivate automatic or suggested updates in Roon Remote for all connected devices and do not accept them if the system asks
Which systems will be affected?
The most important question is answered by looking at your operating system. The following will be blocked from operating as a Roon Server starting April 27th, 2026:
- Apple Macintosh, older systems with macOS 11 Big Sur as well as all macOS 10 versions (like Catalina)
- QNAP with QTS, all available versions will be affected
- Synology NAS with DSM 7.1, DSM 7.0 or earlier
- Linux servers with older variants released before approximately 2019
- High-end music servers that use their own operating systems based on older Linux, this can potentially affect all manufacturers that do not use ROCK
For the latter high-end music servers, where the manufacturer also provides or keeps the operating system up to date, the situation is unclear. An inquiry with the manufacturer might help.
Audiophiles whose Roon Server runs on the following operating systems or platforms do not need to worry:
- Windows (all versions)
- ROCK or Nucleus (Roon’s own operating systems), even on third-party hardware
- Macs running macOS 12 Monterey or higher, introduced since 2021
- Asustor from ADM4.1
Users of these systems don’t have to do anything and may even benefit from better performance.
What Roon users absolutely must consider now
This FAQ clarifies the most important points, explains the technical background, and shows what options users now have.
Because it’s not an ordinary update. With the switch to .NET 10, Roon is fundamentally changing its technical basis. Many existing operating systems no longer meet the new requirements. For numerous users, this means that their previously stable setup will be rendered unusable immediately after the update. The reason is new minimum operating system requirements; the software manufacturer Roonlabs names “glibc 2.27 and OpenSSL 1.1.1” as minimum interfaces for Linux servers, for example. These have been common since about 2019 but were often only integrated into the respective current OS. The age of the hardware is not a criterion.
All devices running an older operating system that has not yet integrated the interfaces. QNAP models with QTS are particularly affected in all versions, but also Mac Minis with macOS 11 Big Sur or macOS 10.x versions (Catalina or older), which are popular as Roon Cores. For many high-end music servers that use their own operating system, it is simply not known what will work and what will not.
QNAP relies on the QTS and QuTS hero operating systems, which are based on their own Linux adaptation. QNAP itself has determined that since 2018, the components of the operating system, especially the so-called glibc interface, no longer receive updates to newer versions. Roon Server can no longer function directly on QTS 5.x or QuTS hero 5.x and never will.
There are indications of a future QTS 6.0 and QuTS hero 6.0, but an early introduction is unlikely. For QuTS hero 6.0, which is actually intended for large professional servers, the beta phase is only slowly beginning, so initial functional tests are expected soon (as of April 2026).
From the moment of the update, the Roon server will no longer function with an operating system that falls below the minimum requirements. This means Roon will not even start.
If the operating system can be replaced or updated to meet the minimum requirements, continued operation after the update will be possible without problems.
Roon is adopting a modernized technical basis to enable better performance and more stability with lower memory usage (RAM). In the past, there were often reports of slower response times, increased RAM consumption, or instability.
The disadvantage is that older or less flexible systems are left out.
That depends on the platform.
For some Macs, it is possible to upgrade to macOS 12 Monterey. This applies particularly to various Apple computers produced after 2015. A hardware upgrade in the form of more storage/RAM may be advisable here. The Mac Mini with Intel Core i5/i7 CPU (“Mac Mini from late 2014”), particularly popular among Roon users, is a special case here, as it was delivered with soldered RAM and cannot be upgraded. However, the 8GB or 16GB variants should easily tolerate newer operating systems.
The same applies to Synology NAS whose hardware is compatible with DSM 7.2 or higher. RAM upgrades are often easy here; processor performance is more likely to be the bottleneck, which limits Roon’s performance anyway.
For Asustor, most machines powerful enough for Roon should already have a sufficiently compatible ADM4.1 or higher installed.
Anyone with a Linux server or NAS with appropriate capabilities, as well as basic knowledge of manual installation and setup, can run Roon Server in a Docker container. This is particularly recommended for owners of QNAP NAS.
Switching hardware platforms or operating system bases is often possible, for example, to an officially supported platform like Roon ROCK. However, this locks the respective server out of other typical applications (only Roon Server runs on ROCK, nothing else), which is likely not an option for NAS systems.
A Docker container is a virtual machine that runs with its own newer operating system on top of the older, no longer compatible operating system. It essentially simulates an additional computer with the newer system.
On the affected QNAP and Synology NAS systems, there is an application that allows setting up and commissioning Docker containers. The respective application only needs to be installed. For QNAP, this is Container Station; for Synology, it can be done via Docker management and the Container Creation Wizard.
A corresponding container already exists in the Roon Community, and Roon has announced its own, particularly simple Docker solution for launch on April 20, 2026. We are waiting to see what this will look like and will provide a guide later.
Yes, that should remain possible with all Roon Server variants that have a version number of B 1641 or lower.
However, it is important to disable automatic updates on both the server and all connected devices, including smartphones and tablets with Roon Remote, and to generally refuse updates. The corresponding function can be found in the settings in the Roon Remote App, under “About Roon.”
In the long term, however, these servers will be excluded from new features, updates, and security patches. A version conflict with mobile devices running newer generations of Roon Remote cannot be ruled out either. As a temporary solution, until new operating systems or workarounds like a Docker container are set up, this solution should work. If you set it up in time.
For owners of QNAP NAS, older Synology and Apple Mac devices with older operating systems, as well as high-end music servers with unknown operating systems: Very urgent.
