Will an HP Thunderbolt Dock Work With a Mac? 7 Dock Specs
Yes, an HP Thunderbolt dock will work with a Mac for charging, USB and Ethernet. The part that breaks is two monitors. Plug both into the dock's DisplayPort and HDMI ports and macOS shows the same picture on both. I went looking for the reason HP's own pages give, which is that "HP does not provide Ethernet and audio drivers on Mac PCs." That turned out to be the wrong thing to worry about. The display rule is the one that sends docks back.
On 2026-10-05 I read four HP documents (the Thunderbolt Dock G4 white paper, the G6 100W data sheet, and the Ultra G6 QuickSpecs and white paper), three Dell documents (the Apple-hosts support article, the SD25TB5 user guide and Dell's 21-page dock compatibility guide) and five owner threads. I also checked which Ethernet chips the drivers on this Mac mini recognize. What I didn't do: I don't own any of these docks and haven't plugged one into a Mac. Every claim about a specific dock comes from the vendor's paper or from an owner's post, and both are linked.

Sources for each row: the HP Thunderbolt Dock G4 technical white paper, the HP Thunderbolt 4 Ultra G6 white paper, the HP Thunderbolt 4 100W G6 data sheet, Dell's Dell Thunderbolt Docks and Apple USB-C Hosts article (last modified 2026-04-19, covering WD19TB, WD19TBS, WD22TB4 and SD25TB4) and the SD25TB5 user guide, which says only that the dock is "Thunderbolt certified for macOS devices, but users may experience some limitations with macOS." Dell's own dock compatibility guide (updated 2026-06-26) mentions Apple zero times in 21 pages, and it now files the WD22TB4 under "previous generation."
Why two monitors mirror on a Mac
These docks have four video outputs, and a Mac can't drive four displays through one Thunderbolt cable. The DisplayPort and HDMI ports on the back are fed by a DisplayPort MST hub, which splits one video stream across several connectors. Windows can use MST to extend a desktop across those connectors. macOS can't, so it sends the same image to each one. Dell's article says it in a single line: "The displays are mirrored if both the monitors are connected using the DisplayPort on the dock."
The fix both vendors print is the same. Dell: "One monitor must be first connected using the DisplayPort port (DP, HDMI, USB-C port) and the other monitor must be connected using the Thunderbolt port on the dock." HP's Ultra G6 white paper gives the same instruction for M4, M4 Pro and M4 Max MacBook Pros. It also caps the result at "1x 4k @ 60Hz, 1x 2k @ 60Hz," so the second screen tops out lower than the first. My reading of both rules is that the downstream Thunderbolt port gets its own video stream, separate from the MST group. You'll need a USB-C or Thunderbolt monitor, or a USB-C to DisplayPort cable, for that port.
Your Mac's own limit still applies on top of the dock's. Base M1 and M2 MacBooks drive one external display, and as a DisplayLink staff member told an M2 MacBook Air owner with a WD22TB4, "you will not get around the limit" with this dock, because it has no DisplayLink chip. On a desktop the math is different. My Mac mini M4 external display notes cover the base M4's three-display combinations. Through one dock cable you get two of those, and the third goes into the mini's own HDMI port.
"HP does not provide Ethernet and audio drivers" for Mac
That sentence appears in all four HP documents, ten times in total. It sounds like the Ethernet port won't work. On this Mac it reads differently. HP's G4 white paper says that over a Thunderbolt connection the dock's active network chip is an Intel I225-LMvP. Apple's built-in Intel Ethernet driver on macOS 26.4.1 matches Intel network devices tunneled over Thunderbolt and carries that chip's name:
$ plutil -p /System/Library/DriverExtensions/com.apple.DriverKit-AppleEthernetE1000.dext/Info.plist | grep IOPCI
"IOPCIClassMatch" => "0x02000000&0xffffff00"
"IOPCIMatch" => "0x00008086&0x0000ffff"
"IOPCITunnelCompatible" => true
$ strings -a .../com.apple.DriverKit-AppleEthernetE1000 | grep -E "I22[56] LMVP"
Intel(R) I225 LMVP
Intel(R) I226 LMVPSo HP doesn't ship a driver because Apple already does. The Ultra G6 is different on paper: it uses its Intel I226 chip only for vPro PCs and gives everything else, a Mac included, a Realtek 2.5G USB chip. HP doesn't name that chip's model. If it's the RTL8156 family, Apple's Realtek patcher lists it, as I found when I looked at Mac mini M4 docks with 2.5GbE. The Dell article marks Ethernet as working on Apple hosts. Audio I couldn't settle. HP gives no driver and no detail, and the WD19TBS and WD22TB4 have no 3.5mm jack at all, so Dell's Apple table marks headset audio as no.
What owners report
Five threads, all about Macs on HP or Dell business docks. All five start with a mirrored or missing screen, and the two that report a fix both used the dock's Thunderbolt port. An M3 MacBook Air owner with an HP Thunderbolt Dock G4 and two DisplayPort monitors got "Input Signal Out of Range" on one screen and a half-working second screen. The thread ended with no fix through the dock; another member got two displays by cabling them straight to the laptop. An M4 MacBook Air owner (May 2025) was asking about the WD22TB4 because an HP G5 USB-C dock had mirrored their two 4K monitors. A reply quoted Dell's mirror sentence and said to put one screen on the Thunderbolt port. In a Dell community thread on the WD19TB, one M3 MacBook Pro owner gave up and switched to Dell's DisplayLink D6000. An M4 Pro owner later in the thread got both screens extended with a DP cable plus a DP-to-USB-C cable into the Thunderbolt port.
The clearest success is a Mac mini M4 Pro on a Dell Thunderbolt dock (January 2025). The ultrawide was mirroring at reduced resolution until the owner moved it to the dock's Thunderbolt port with a Thunderbolt cable and left the other monitor on DisplayPort.
What you lose on a Mac even when it works
Dell's table is blunt. On Apple hosts, charging stops at 96W instead of 130W, and Wake on Dock, Wake-on-LAN and MAC address pass-through don't work. Firmware updates need "a Dell Windows operating system computer," or Dell's remote management tool. HP limits firmware updates to Windows, with Linux also allowed on the G4 and the Ultra G6. The Ultra G6 white paper says the dock's power button and power LED don't work with Apple laptops. If you only own Macs, you can't patch the dock's firmware yourself. That matters more than it sounds, because both vendors' fix for most dock bugs is a firmware update. HP's G4 paper lists its supported macOS as "MacOS Big Sur 12.1." Big Sur is macOS 11 and 12.1 is Monterey, which tells you how closely the Mac column gets read.
Should you buy one for a Mac?
If your employer hands you one, use it. Put one monitor on the Thunderbolt port and you have a working two-screen desk. Buying one new for a Mac is harder to argue for. As an Amazon Associate I earn from qualifying purchases. Prices on 2026-10-05, read with a New York delivery address: the Dell WD22TB4 was $158.59, shipped by Amazon from a third-party seller, and Dell's article covers it for Macs by name. The Dell SD25TB4, a current model covered by the same article, was $199. The HP Thunderbolt Dock G4 was $249 from a third-party seller. HP never documents the Mac display rule for it, and its price is close to that of docks sold for Macs, which I compared in docking station vs USB hub for a Mac mini. I haven't used any of the three. If one-cable dual monitors is the whole point, my count of USB-C KVM switches with dual-monitor claims found the same MST trap there.
FAQ
Will an HP Thunderbolt dock work with a MacBook?
Yes for charging, USB and Ethernet. HP lists macOS as supported on the Thunderbolt Dock G4 and the G6 docks but says it doesn't provide Ethernet or audio drivers for Macs. macOS has its own driver for the G4's Intel I225-LMvP network chip. Two monitors on the dock's DisplayPort and HDMI ports will mirror; put one on the dock's Thunderbolt port to extend.
Why do my two monitors mirror on a Dell or HP dock with a Mac?
The dock's DisplayPort and HDMI ports share one video stream through a DisplayPort MST hub, and macOS doesn't support MST for an extended desktop, so it mirrors. Dell and HP both say to connect one monitor to a DisplayPort or HDMI port and the other to the dock's downstream Thunderbolt port. Base M1 and M2 MacBooks support only one external display regardless.
How much power does a Dell Thunderbolt dock give a MacBook?
Dell's Apple-hosts article says the WD19TB, WD19TBS, WD22TB4 and SD25TB4 deliver up to 96W to Apple computers, compared with 130W for Dell laptops. The newer SD25TB5 lists up to 240W for non-Dell computers. HP rates the Thunderbolt Dock G4 at up to 100W and the Ultra G6 at up to 180W over the cable for PD 3.1 hosts.

Method: on 2026-10-05 I downloaded HP's four dock documents and Dell's compatibility guide as PDFs and searched the extracted text with pdftotext; Dell's support article and SD25TB5 guide were read on dell.com. Owner reports come from three Apple Community threads, one Dell community thread and one DisplayLink forum thread; HP's own support forum returned 403 to every request, so none of its threads are quoted. The driver output is from this Mac mini (Mac16,10, macOS 26.4.1), which has no dock attached, so it shows what macOS can match, not a working connection. Amazon prices were read on the mobile site with a New York 10001 delivery address. The ASIN in my weekly plan for the HP G4 turned out to be the older G2, so I linked a listing that names the G4 part number, 4J0A2AA.
