Host Deps
The tools PC Agent needs on your computer: what each row means and how to fix one.
Host Deps checks the computer that runs PC Agent. Every row must be ready before an iPhone can work. Fix rows here, top to bottom.
1. Open Host Deps
-
In the left menu, press Host Deps.
-
At the top: how many rows are ready (… ready) and your computer's system.
The page shows only the rows for your computer's system (Windows or macOS).
2. Read a row
Each row is one tool on your computer. The word on the right is its status:
| Status | Meaning | Do |
|---|---|---|
| ready | Works | Nothing |
| checking / installing | PC Agent is working on it | Wait |
| missing | Not installed or not found | Press the row's button (section 3) |
| not running | Installed but stopped | Press Start or Restart |
| failed | The last fix did not work | Press Retry or Repair |
| not required / n/a on host | Not needed on this computer | Nothing |
| unknown | No news from PC Agent yet | Wait a minute |
3. Fix a row
-
Press the row that is not ready. It opens and says what is wrong.
-
Press the button it offers: Install, Start, Restart, Repair, Reinstall or Re-verify. Press it once.
-
Your computer asks for permission? Allow it.
-
Wait. The row shows Installing… or Running…, then Completed.
Done when: the row says ready. Fix the next row, until all rows are ready.
A row says Blocked: … must be healthy first? Fix the row it names first.
4. Windows: Apple Mobile Device Service
Windows needs Apple's service to talk to an iPhone over the cable. This row has no button: you install it once by hand.
-
Press the Windows Start button, type
Terminal, open it. -
Paste this line and press Enter:
winget install --id Apple.AppleMobileDeviceSupport -e -
Accept what Windows asks. Wait until it says it is installed.
-
Back in Titan, wait until the Apple Mobile Device Service row says ready.
Install Apple Mobile Device Support, not the Apple Devices app from the Microsoft Store.
5. macOS: background items
macOS can switch off the parts of PC Agent that run in the background. A row that keeps going back to not running on a Mac often means this.
-
Open System Settings → General → Login Items & Extensions.
-
Under Allow in the Background, turn on the items for PC Agent.
-
Back in Titan, press Repair or Re-verify on the row.
