Best NAS Devices for Mac Users
NAS (Network Attached Storage) devices on a Mac network serve two primary functions: Time Machine backups across multiple Macs simultaneously, and shared file access for teams or households. The key Mac compatibility requirements are SMB or AFP file sharing (macOS uses both), Time Machine destination support, and — for video and creative workflows — sustained write speeds that prevent backup bottlenecks. Most NAS devices support macOS natively; the differentiator is how well the software integrates with Mac-specific features like Time Machine.
We selected these based on macOS compatibility, Time Machine support, number of drive bays, Synology’s DSM software ecosystem (which leads the category for Mac users), network speeds, and practical fit for professionals and small teams using Apple hardware.

Synology DS223
Best for: The reliable entry-level 2-bay NAS for Mac users — DSM software, Time Machine support, quiet operation
The Synology DS223 runs DiskStation Manager (DSM), Synology’s operating system that is the benchmark for NAS software: it provides a clean web UI, Active Backup for Mac (Time Machine compatible), Cloud Sync to major cloud services, and a Moments/Photos app for photo organization. Two drive bays support up to 32TB with 16TB drives (in RAID 1 for redundancy). Dual Gigabit Ethernet provides network throughput up to ~120 MB/s. The DS223 is specifically built for SMBs and home offices using macOS as the primary OS.
Key specs: 2-bay, Realtek RTD1619B CPU, 2GB RAM, dual Gigabit Ethernet, USB 3.2, RAID 0/1/JBOD, DSM OS, Time Machine support, up to 32TB raw
Caveat: Drives sold separately. Gigabit Ethernet limits sustained network speed to ~120 MB/s — sufficient for document backup but slow for large video library transfers. No 10GbE without PCIe expansion (not available on DS223).
Price: Mid-range (enclosure only; drives additional).
Synology DS723+
Best for: 2-bay NAS with optional 10GbE expansion for Mac users with high-throughput needs
The DS723+ is Synology’s 2-bay NAS with a PCIe Gen 3 expansion slot — allowing addition of a 10GbE or 25GbE network card for high-speed file transfer. With 10GbE, sustained throughput can exceed 1000 MB/s for video editing workflows or fast Time Machine backups of large drives. AMD Ryzen R1600 dual-core processor handles heavier workloads including Plex transcoding and multiple concurrent connections. The DS723+ scales from home office to small professional team use.
Key specs: 2-bay, AMD Ryzen R1600 dual-core, 2GB ECC RAM (expandable to 32GB), dual Gigabit Ethernet, PCIe Gen 3 (10GbE expansion), USB 3.2, DSM OS, Time Machine support
Caveat: 10GbE requires a compatible network card (sold separately, ~$100–150) and a 10GbE network switch or direct connection. Without 10GbE, it performs similarly to the DS223 at Gigabit speeds.
Price: Mid-to-premium range (enclosure only).
Synology DS923+
Best for: 4-bay NAS for growing teams with multiple Macs, larger storage needs, and optional SSD caching
The DS923+ expands on the DS723+ with four drive bays — supporting RAID 5 (three-drive redundancy with full capacity of three drives) or RAID 6 (two-drive redundancy). Four bays allow raw capacity of up to 64TB (16TB drives × 4). The PCIe expansion slot supports 10GbE or M.2 SSD caching cards for read/write acceleration. DSM handles multiple Mac Time Machine destinations simultaneously — each Mac can have its own backup quota. Suitable for teams of 5–20 users.
Key specs: 4-bay, AMD Ryzen R1600 dual-core, 4GB ECC RAM (expandable to 32GB), dual Gigabit Ethernet, PCIe Gen 3 expansion, M.2 2280 ×2 (SSD cache), DSM OS, RAID 0/1/5/6/10
Caveat: Drives sold separately. RAID 5 requires minimum three drives. Larger footprint and louder than 2-bay units. Full feature set (10GbE, SSD cache) requires additional hardware purchases.
Price: Premium range (enclosure only).
QNAP TS-233
Best for: Budget-accessible 2-bay NAS for Mac users who need Time Machine and basic SMB file sharing
The QNAP TS-233 is a 2-bay NAS at an entry price point — lower than comparable Synology units. It supports Time Machine via AFP/SMB, file sharing, and basic media serving via QTS (QNAP’s operating system). QTS is functional but less polished than Synology DSM. Gigabit Ethernet, USB 3.2, and RAID 0/1/JBOD are standard. A practical entry option for users who need basic Mac backup without the Synology price premium.
Key specs: 2-bay, ARM Cortex-A55 quad-core, 2GB RAM, Gigabit Ethernet, USB 3.2, RAID 0/1/JBOD, QTS OS, Time Machine support
Caveat: QTS software has a steeper learning curve and less polished Mac integration than Synology DSM. No PCIe expansion slot — Gigabit only, no 10GbE upgrade path. QNAP has had firmware security vulnerabilities in the past — keep firmware updated.
Price: Budget to mid-range (enclosure only).
WD My Cloud Home Duo
Best for: Non-technical Mac users who want plug-and-play home NAS without configuring RAID or NAS software
The WD My Cloud Home Duo is a closed-ecosystem NAS — drives are pre-installed and non-removable in the standard configuration, and setup is handled via the WD app with no manual configuration required. Time Machine backup is supported. The My Cloud app provides remote access from iPhone and Mac. Not suited for multi-user team environments or technical customization — it is designed as a “set and forget” backup device for home users and individuals.
Key specs: 2-bay with pre-installed drives (4TB, 8TB, 12TB, 16TB options), Gigabit Ethernet, USB 3.0, Time Machine support, WD My Cloud app (iOS/macOS), plug-and-play setup
Caveat: Closed ecosystem — drives cannot be individually replaced in standard use and you cannot install third-party apps. Not suitable for technical users or teams who need full NAS control. No RAID 1 in default setup — uses JBOD by default (can be configured to mirror).
Price: Mid-range (includes pre-installed drives).
How to choose
- Time Machine requirements: macOS Time Machine backs up over SMB. Any NAS with SMB and adequate Time Machine share support works. Synology DSM has the most reliable Time Machine implementation, including per-user quotas and multiple simultaneous Mac backups.
- Number of bays: Two bays allow RAID 1 (one backup copy, half capacity) or JBOD (two separate drives). Four bays allow RAID 5 (one-drive fault tolerance) for more capacity-efficient redundancy. For a single Mac household, 2-bay RAID 1 is sufficient. For teams or large media libraries, 4-bay is more practical.
- Network speed: Gigabit Ethernet (~120 MB/s real throughput) works for document backup and file access. Video editing workflows require 10GbE (~1000 MB/s) to avoid waiting during transfers. If you work with ProRes or RAW footage, budget for 10GbE on both the NAS and your Mac (via Thunderbolt dock or PCIe card).
- Synology vs alternatives: Synology DSM is the most Mac-compatible NAS OS available. For non-technical users, Synology’s setup wizard and Active Backup for Business make Mac backup straightforward. QNAP offers comparable hardware at lower prices but with less polished Mac integration. WD My Cloud is the only option that requires no NAS knowledge at all.
