Vous n'avez pas de Mac Silicon, mais vous avez vu passer mon article de ce matin sur vLLM-MLX et son serveur d'IA local ? Hé bien bonne nouvelle, je suis tombé ce midi sur Lemonade SDK , un serveur d'IA local communautaire sponsorisé par AMD (et largement codé par leurs ingénieurs), qui joue dans la même cour, mais côté PC + Mac !

C'est la même logique qu'avec vLLM-MLX, vous installez le serveur (un paquet clé en main selon votre OS, pas de bidouille pip), et il expose un endpoint compatible API OpenAI sur http://localhost:13305/api/v1. Vos scripts tapent dessus au lieu d'envoyer vos prompts, et votre pognon, chez OpenAI.

Le démarrage tient en une ligne. Un lemonade run Gemma-4-E2B-it-GGUF lance un modèle, et un lemonade launch claude branche carrément Claude Code sur votre machine.

Sauf que là où vLLM-MLX s'appuie sur MLX pour les puces Apple, Lemonade vise les NPU Ryzen AI et les GPU Radeon. Et c'est tout l'intérêt du truc car depuis la 10.0 sortie en mars, le NPU XDNA2 des machines Ryzen AI récentes sert enfin à faire tourner des LLM sous Linux, et plus juste à décorer la fiche technique !

La 10.5 apporte également 2 nouveautés qui valent le coup. D'abord, le support macOS passe de bêta à officiel. Toutes les grosses fonctions sont validées sur Mac (le texte via llama.cpp et Metal, le reste via les autres moteurs embarqués) et ensuite, ça bascule sur ROCm 7.13 pour llama.cpp et la génération d'images.

J'ai pas de PC Ryzen AI sous la main pour tâter du fameux NPU, donc j'ai fait mes tests sur mon GPU Metal à moi. Notez qu'un lemonade list crache tout le catalogue, Qwen, Gemma, Llama, DeepSeek et compagnie.

Et ça dépote ! Un petit Qwen3-0.6B dans le chat intégré tourne à ~96 tokens par seconde avec mes 32 Go de RAM, c'est donc une réponse quasi instantanée. Après un modèle de 0,6 milliard de paramètres, c'est le poids plume du ring, donc comptez nettement moins sur un gros 8B, mais ça tourne nickel.

Du coup, sur Mac, vLLM-MLX joue la carte du natif Apple via MLX, alors que l'intérêt de Lemonade c'est surtout le cross-plateforme et le NPU Ryzen AI. Et comparé à Ollama , vous gagnez ce NPU mais aussi les fonctions audio (synthèse vocale, transcription) + un gestionnaire graphique de modèles pour piocher vos modèles. Et tout ça est sous licence Apache 2.0.

Bref, que vous soyez team Mac ou team Ryzen, c'est zéro ligne de facture API en fin de mois et surtout vos données qui restent chez vous !

Andrey Letov vient de sortir Notepad++ for Mac , un portage natif Apple Silicon de l'éditeur culte créé par Don Ho. Notez quand même que Don Ho n'a rien à voir avec ce projet. C'est un portage communautaire indépendant, lancé en mars dernier.

Vous récupérez le binaire universel qui tourne nativement sur les puces M1 à M5 et sur les vieux Macs Intel. C'est de l'Objective-C++ compilé pur jus avec le même moteur d'édition Scintilla qu'utilise la version Windows (Scintilla est cross-platform avec un build Cocoa officiel).

Après, tout le reste a dû être refait à la main, parce que le Notepad++ original utilise massivement Win32 pour son interface. Letov a donc réécrit la couche UI from scratch en Cocoa pour coller aux conventions macOS, avec menus, dialogues, file pickers et raccourcis clavier qui se comportent comme ceux d'une vraie app Mac.

L'interface de Notepad++ sous macOS

Côté prérequis, comptez sur macOS 11 (Big Sur) au minimum, en dessous ça ne tournera pas. Donc si vous êtes resté sur Catalina ou plus vieux, ouais, désolé pour vous, faut passer votre tour.

Côté fonctionnalités, on retrouve le pack classique du Notepad++ qu'on connaît, coloration syntaxique pour 80 langages, recherche regex, find in files, bookmark de lignes, recherche incrémentale, split view pour bosser sur deux fichiers en parallèle, enregistrement de macros pour automatiser les tâches répétitives, écosystème de plugins, et l'interface dispo dans plus de 90 langues.

C'est gratuit, sous licence GPL v3 mais attention quand même, les plugins Windows compilés en .dll ne sont pas portables tels quels. Il vous faudra une version macOS recompilée pour chacun, et le catalogue dispo aujourd'hui est forcément plus maigre qu'en face. Bref, du Notepad++ comme on l'aime, mais avec moins d'extensions pour l'instant.

Après tant que Letov tiendra le rythme, ça roulera, mais le jour où il décrochera ou que la version Windows partira dans une direction qu'il ne suit pas, le port macOS va probablement diverger ou s'éteindre. On verra bien.

En attendant, si vous bossez sur Mac et que Notepad++ vous manque depuis votre époque Windows (on fait tous des erreurs ^^), foncez le tester, l'app a l'air bien fichue à première vue et le projet itère vite.

Bref, j'espère que ça durera.

New Thunderbolt 5 NVMe Storage Solution Revealed – The OWC 4M2 Ultra

OWC has introduced the Express 4M2 Ultra at NAB 2026 as a compact 4 bay NVMe enclosure built around Thunderbolt 5. It is designed as a DIY storage solution for users who want to install their own M.2 SSDs and configure the enclosure for different RAID modes, including RAID 0, 1, 4, 5, 10, and JBOD. OWC positions it as a high performance option for media production, post production, and other bandwidth intensive workloads that benefit from fast external solid state storage.

The enclosure supports up to 4 NVMe M.2 drives in 2280 or 2242 formats and is rated for up to 6622MB/s in RAID 0 when paired with PCIe 4.0 or newer SSDs on Thunderbolt 5 systems. It also retains backward compatibility with Thunderbolt 4, Thunderbolt 3 on Mac, and USB4 hosts, though throughput is lower on 40Gb/s connections. Capacity starts with whatever drives the user installs, with support for up to 32TB in a single unit based on current 8TB SSD support, while additional units can be daisy chained for larger storage pools.

OWC Express 4M2 Ultra – Design & Storage

The Express 4M2 Ultra uses a compact aluminum enclosure with a vertical desktop form factor intended to keep its footprint relatively small. OWC states that the chassis is built from aircraft grade aluminum, which serves both as the structural housing and as part of the thermal design. The unit measures 12.3 cm tall, 11.7 cm long, and 6.0 cm wide, with a listed weight of 900 g.

Internally, the enclosure provides 4 drive bays for NVMe M.2 SSDs and supports both 2280 and 2242 form factors. It accepts single sided and double sided drives, though SSDs with integrated heatsinks are not supported. OWC specifies support for PCIe Gen 3 and later SSDs, with Gen 4 and newer drives recommended for higher performance. Each bay operates at PCIe 4.0 x1, and single drive performance is rated at up to 1600MB/s.

From a storage flexibility standpoint, the enclosure is aimed at users who prefer to source and install their own drives rather than buy a preconfigured array. That allows the capacity and performance profile to vary depending on the SSDs installed. With current 8TB drives, the maximum listed capacity is 32TB in a single enclosure, while future higher capacity drives could increase that figure without requiring a new chassis.

RAID support is handled in software rather than through a dedicated hardware RAID controller. The Express 4M2 Ultra supports RAID 0, 1, 4, 5, 10, and JBOD, with OWC highlighting SoftRAID as its main management option. This gives users a wider range of configuration choices depending on whether they prioritize throughput, redundancy, usable capacity, or a balance between those factors.

Thermal management is handled by a 40mm cooling fan with multiple speed thresholds tied to internal temperature. According to OWC’s listed profile, the fan remains off below 35°C, then ramps progressively from 40% to 100% as temperatures rise from 35°C to 55°C and above. The stated approach is to reduce unnecessary noise under lighter workloads while maintaining SSD performance during sustained transfers.

OWC Express 4M2 Ultra – Ports and Connections

The Express 4M2 Ultra uses Thunderbolt 5 as its primary host interface, with 1 USB C host port rated for up to 80Gb/s. OWC also lists support for USB Attached SCSI Protocol, and the enclosure is designed to work across Thunderbolt 5, Thunderbolt 4, USB4, and Thunderbolt 3 on supported Mac systems. In practice, that gives it a broader compatibility range than a Thunderbolt 5 only accessory, though maximum throughput depends on the bandwidth available from the connected system.

A second Thunderbolt 5 port is included for downstream connectivity. OWC states that this allows users to daisy chain up to 5 additional Thunderbolt devices, along with 1 USB peripheral, from the same connection path. The same port can also be used to connect additional Express 4M2 Ultra units, with OWC positioning that as a way to build larger storage volumes without treating each enclosure as an entirely separate destination.

Compatibility varies by platform and interface generation. On newer Thunderbolt 5 Macs and PCs, OWC rates the enclosure at up to 6622MB/s, while Thunderbolt 4 and USB4 systems are listed at up to 3200MB/s. Intel Macs with Thunderbolt 3 are rated up to 2800MB/s, and OWC notes that Thunderbolt 3 support is Mac only. No driver is required, and the enclosure is listed as compatible with macOS 14.x Sonoma, macOS 15.x Sequoia, macOS 26.x Tahoe, Windows 11, and Linux, with some features depending on OS version and connection type.

OWC Express 4M2 Ultra – Price and Release date

OWC has set the starting price of the Express 4M2 Ultra at $399.99 for the standard non SoftRAID version. A version bundled with SoftRAID is priced at $549.99. As a result, the enclosure enters the market as a premium DIY storage option rather than a low cost external SSD enclosure, with the final overall build cost depending heavily on the NVMe drives a buyer installs.

The company says the Express 4M2 Ultra is available for pre order now following its reveal at NAB 2026 in Las Vegas. OWC lists shipping for Q3 2026, so early buyers will still be waiting several months for general availability. That places the launch window firmly in the second half of the year, even though orders have already opened.

Si vous voyagez avec un Macbook qui contient des trucs trèèèès sensibles, faut absolument que vous alliez tester cet outil.

PanicLock est le bouton "panique" qu'Apple n'a jamais voulu faire. Grâce à cela, en un clic, Touch ID se désactive totalement.

Plus de biométrie, et retour au mot de passe obligatoire pour rouvrir la session. Parce que oui, Touch ID, c'est ultra pratique au quotidien, sauf quand un agent à la frontière ou un flic un peu trop curieux vous demande gentiment (ou de force) de poser votre doigt sur le capteur de votre machine.

Sur iPhone, Apple a prévu quand même une astuce (5 pressions sur le bouton latéral et la biométrie se désactive). Mais sur Mac, rien !

Le principe de PanicLock, c'est tout simplement de cliquer sur l'icône dans la barre de menu ou d'appeler un raccourci clavier de votre choix et voilà ! Votre Mac se verrouille alors en désactivant Touch ID au passage.

Les devs ont aussi prévu une option "Lock on Close" qui déclenche le panic mode automatiquement lorsqu'on referme l'écran du Macbook, ce qui est la fonctionnalité la plus utile de tout le pack ! Vous fermez l'écran, et c'est mort, faut le mot de passe !

Sous le capot, ça fonctionne grâce à des fonctions natives de macOS qui sont tout simplement détournées pour permettre de désactiver la biométrie en 2 secondes. Notez que le code de PanicLock est sous licence MIT, et fonctionne 100% en offline.

Alors pourquoi c'est utile au-delà de la paranoïa que vous vous trimballez depuis que vos parents vous ont appris que vous aviez un frère adoptif secret ?

Hé bien y'a une vraie distinction juridique en jeu que j'évoquais d'ailleurs récemment dans mon article sur les cartes bancaires biométriques . En effet, aux États-Unis, la justice est divisée car en janvier 2025, la cour d'appel fédérale du District of Columbia a tranché dans US v. Brown que forcer quelqu'un à déverrouiller son téléphone violait le 5e amendement, parce que ça revient à témoigner contre soi-même.

Alors que la cour d'appel fédérale de l'Ouest Américain, elle, considère qu'un déverrouillage biométrique reste un acte physique qui n'est pas un témoignage, donc forçable. Et là, désactiver Touch ID avant un contrôle change donc tout puisque grâce à ça, on bascule dans le cas "mot de passe obligatoire", qui est mieux protégé légalement dans plusieurs juridictions. C'est exactement la même logique que la fonction iOS 18 qui affole la police , transposée côté Mac.

Je ne suis pas expert, mais je crois qu'en France, c'est un petit peu la même chose avec notre droit à ne pas nous auto-incriminer.

Côté limites, PanicLock désactive Touch ID, et c'est tout, donc si vous avez l'unlock par Apple Watch ou via une clé de sécurité, votre Mac restera quand même "ouvrable" autrement. Il faut donc penser à désactiver ces méthodes en parallèle si vous êtes vraiment dans une situation à risque.

Pour l'installer, c'est:

brew install paniclock/tap/paniclock

Si un Mac reste allumé trop longtemps, il risque de perdre l'accès au réseau après exactement 49 jours, 17 heures, 2 minutes et 47 secondes d'activité.

UniFi and the Airwire – Did Ubiquiti just SOLVE Everyone’s WiFi MLO Issue?

Ubiquiti has introduced the UniFi AirWire, a WiFi 7 client adapter designed to address one of the more limited areas of current WiFi 7 deployment: the client side. While WiFi 7 access points and routers have been marketed heavily around Multilink Operation, many currently available client devices still rely on single-radio implementations that switch between bands rather than maintaining simultaneous links. The AirWire is positioned as a dedicated external client that aims to deliver true STR MLO operation across 5 GHz and 6 GHz, with Ubiquiti claiming improved throughput, lower latency, and better resilience than conventional integrated client hardware.

At a hardware level, the AirWire is a USB-C connected WiFi 7 adapter with a 4-stream design, support for 5 GHz and 6 GHz 2 x 2 MU-MIMO operation, and a quoted uplink capability of up to 5.8 Gbps on 6 GHz and 4.3 Gbps on 5 GHz. It also adds a high-gain antenna design and a dedicated scanning radio for real-time spectrum analysis. At $199, this places it well above the cost of generic USB wireless adapters, but it is also targeting a more specific role: enabling multi-gigabit wireless client connectivity in environments that already have the access point infrastructure to support it.

You can buy the Airwire via the link below – doing so will result in a small commission coming to me and Eddie at NASCompares, and allows us to keep doing what we do! 

UniFi Airwire – Design

The UniFi AirWire has a noticeably different physical design to the compact USB WiFi adapters that are typically associated with desktop or laptop client upgrades. At 117 x 117 x 42.5 mm and 537 g, it is much closer in appearance to a standalone wireless bridge or directional client than a conventional dongle. That larger enclosure is directly tied to its intended function, as Ubiquiti is clearly building around higher power operation, larger antenna structures, and the thermal requirements that come with sustained WiFi 7 activity across multiple radios.

The housing is made of polycarbonate and includes a fold-out top section that appears to be part of the antenna assembly and directional positioning of the unit. This gives the AirWire a more deliberate deployment profile, where placement and orientation are likely to matter more than they would with an internal laptop radio or a low-profile USB adapter. On the front, there is also a 0.96-inch status display, which provides at-a-glance information during setup and operation without needing to rely entirely on software feedback from the host system.

From a practical standpoint, the design reflects that this is not intended to be an invisible add-on for casual wireless use. It is an external client device built to sit on a desk or near a workstation, with a form factor that prioritizes radio performance and signal handling over portability. That makes it less discreet than mainstream client adapters, but it also aligns with the product’s stated purpose as a high-performance WiFi 7 endpoint for users trying to push beyond the limitations of standard integrated wireless hardware.

UniFi Airwire – Internal Hardware

Internally, the UniFi AirWire is built around a dual-band WiFi 7 architecture that focuses entirely on 5 GHz and 6 GHz operation, without any 2.4 GHz support. Ubiquiti rates the device as a 4-stream client, split across 2 x 2 MU-MIMO on 5 GHz and 2 x 2 MU-MIMO on 6 GHz.

This layout is central to its stated role as an STR MLO client, allowing both bands to be active simultaneously rather than relying on the more common single-radio behaviour seen in many current WiFi 7 client devices.

Ubiquiti also specifies a high-gain antenna design, with 11 dBi quoted on both 5 GHz and 6 GHz, which is significantly more aggressive than the antenna arrangements found in most integrated laptop or mobile WiFi hardware. Alongside this, the AirWire includes a dedicated scanning radio for real-time spectral analysis. That separate scanning capability is notable because it suggests the unit is not just focused on link speed, but also on monitoring local RF conditions and interference in parallel with normal client operation.

The trade-off for that hardware approach is power and thermals. Ubiquiti lists maximum power consumption at 18 W, with USB PD 5/9/12V support and separate normal and performance power profiles. In practical terms, that places the AirWire closer to a compact external network appliance than a typical USB wireless adapter. It also helps explain the larger chassis, the need for external power flexibility, and the expectation that sustained performance operation will demand more cooling headroom than a smaller bus-powered client device could realistically provide.

UniFi Airwire – Connectivity

The UniFi AirWire connects to the host system over USB-C, but from a networking perspective it is presented as a 5 GbE interface over USB 3.2 Gen 2. That distinction matters, because although the wireless side of the device is rated far higher in combined theoretical bandwidth, the host connection places an upper practical ceiling on what can be delivered to the attached PC, laptop, or workstation. In effect, the AirWire is designed to behave more like an external multi-gig network adapter than a conventional USB WiFi dongle.

On the wireless side, the AirWire operates on 5 GHz and 6 GHz only, with support for WiFi 7, WiFi 6, WiFi 5, and 802.11n data rates across a wide range of channel widths. Ubiquiti lists support for EHT 20/40/80/160/240/320 MHz, alongside HE, VHT, and HT modes on earlier standards. The maximum quoted link rates are 5.8 Gbps on 6 GHz using 320 MHz bandwidth and 4.3 Gbps on 5 GHz using 240 MHz bandwidth, though actual results will depend heavily on access point capability, spectrum availability, regional channel restrictions, and signal conditions.

Power delivery is also part of the connection design. Ubiquiti specifies USB PD 5/9/12V support, with 15 W in normal mode and 20 W in performance mode, while maximum device power consumption is listed at 18 W. This means that, depending on how the host system is connected and powered, full performance operation may require more than a single low-power USB port can reliably provide. That makes cable quality, port specification, and available USB power budget more relevant here than they would be for standard client adapters.

The AirWire also includes support for wireless meshing and real-time spectral analysis, which extends its connection role beyond basic client access. In a UniFi environment, setup is intended to be handled through UniFi AutoLink for rapid onboarding, reducing the need for separate client-side software installation. Even so, the broader connection experience will still depend on the surrounding infrastructure, particularly whether the connected UniFi access point supports the required WiFi 7 and 6 GHz features needed for the AirWire to operate in the way it is being marketed.

UniFi Airwire – Verdict?

The UniFi AirWire is a more specialised product than its USB-C connection initially suggests. Rather than serving as a low-cost way to add basic WiFi 7 support to a system, it is designed to address a specific gap in the current client ecosystem: the lack of widely available true multi-radio MLO hardware on the device side. Its value therefore depends less on headline wireless specifications alone and more on whether the surrounding network environment is already capable of taking advantage of simultaneous 5 GHz and 6 GHz operation, wider channel support, and multi-gigabit client throughput.

On that basis, the AirWire appears to be an interesting but clearly targeted piece of hardware. The larger chassis, higher power requirements, directional design, and likely dependency on a strong WiFi 7 6 GHz deployment mean it is not a universal client upgrade for every user. However, for users already invested in UniFi WiFi 7 infrastructure and looking for a higher performance external client than the current mainstream market provides, it introduces a form factor and feature set that are still relatively uncommon. Whether that translates into a meaningful real-world advantage will depend on testing, particularly around sustained throughput, latency behaviour, thermal limits, and the practical impact of STR MLO outside of ideal conditions.
