Transfer Files from Mac to Mac Without Wi‑Fi: 6 Methods Compared
For a few photos between two Macs, AirDrop is fine. For a 300 GB Photos library, a Final Cut project or a virtual machine, it's another story: AirDrop stalls, Wi‑Fi takes hours, and the cloud costs money. Here are the six ways to do it, with real‑world speeds and limits.
At a glance
| Method | Typical speed | 50 GB in… | Both directions? | What you need |
|---|---|---|---|---|
| AirDrop | 20‑80 MB/s | 12‑40 min (often interrupted) | One file at a time | Wi‑Fi + Bluetooth |
| Wi‑Fi (File Sharing) | 30‑100 MB/s | 9‑30 min | Yes | Same network |
| Gigabit Ethernet | ~110 MB/s | 8 min | Yes | Adapters + cable |
| External SSD | 400‑2,000 MB/s ×2 | 2‑5 min, twice | No (back and forth) | An SSD, two copies |
| Migration Assistant | variable, slow to prepare | 30 min to hours | No (once, one way) | Reboot / waiting |
| Thunderbolt/USB4 cable + DiskBridge | 1,000‑2,500 MB/s | 30‑60 s | Yes, automatic | One cable, both Macs on |
Speeds depend on the disks and the Macs; the orders of magnitude don't change.
1. AirDrop
Ideal for one file or a handful of photos. Past a few gigabytes the transfer slows down (AirDrop uses a direct Wi‑Fi link whose throughput varies) and often breaks if a Mac goes to sleep. You can't browse the other Mac's files: one sends, the other receives.
2. File Sharing over Wi‑Fi
Turn on File Sharing on one Mac, connect from the other (Finder › Network): you mount its disks and work in them. Convenient, but limited by Wi‑Fi — often 30 to 100 MB/s, and less as soon as the router is far away or busy.
3. Ethernet
Two USB‑C ⇄ Ethernet adapters and a cable: about 110 MB/s at Gigabit, 250 MB/s at 2.5 GbE. Reliable, but you have to buy the adapters, and it's still ten times slower than Thunderbolt.
4. An external SSD
The old‑school way: copy to an SSD, unplug, replug, copy again. Fast per copy, but everything is done twice, and the SSD must be big enough. Thunderbolt Bridge does the same job in one copy, with no drive in between.
5. Migration Assistant
Perfect on the day you change Macs: it moves accounts, apps and settings. It's slow to prepare, works once, and doesn't let you keep working across two Macs afterwards. To keep exchanging files after the migration, you need something else.
6. A Thunderbolt / USB4 cable (Thunderbolt Bridge)
A Thunderbolt 3, Thunderbolt 4 or USB4 cable between two Macs creates a private 10‑40 Gbit/s network: Thunderbolt Bridge. The other Mac's disks mount in the Finder like a server, except that the disk becomes the bottleneck, not the network — around 1 to 2 GB/s between two SSDs.
The drawback is the busywork: find the bridge's address, connect to server, mount the volumes, eject them before unplugging. That's what DiskBridge automates: installed on each Mac, it detects the other as soon as the cable is plugged in, mounts its disks in the Finder, and unmounts them on unplug. Both ways, no account, no setup. See how to link two Macs with a cable.
Which one should you use?
- A few files, now and then: AirDrop.
- A new Mac, once: Migration Assistant, then a cable for everything after.
- Lots of data, often (video editing, photography, backups, two workstations): the Thunderbolt cable with DiskBridge — the only method that is fast, two‑way and hands‑off at the same time.
