# Set Up a Cloud Mac

> A Cloud Mac is a real Mac computer that lives in a data center and stays on 24/7. Instead of leaving a laptop running in your closet, you rent a Mac in the cloud and run the iMessage Sync app there. This is the  way to keep your messages flowing without interruptions.

<Check>
  The iMessage Sync app only works while your Mac is awake and online. A Cloud Mac never sleeps, never loses wifi, and never runs out of battery, so your messages always send and receive instantly.
</Check>

## Why We Recommend This[​](#why-we-recommend-this "Direct link to Why We Recommend This")

We **strongly suggest** renting a Mac in the cloud instead of using your personal laptop.

* **Never Miss a Beat:** 100% uptime means your messages always send instantly.
* **Zero Headaches:** You never have to worry about dead batteries, sleep mode, or a dropped wifi signal.
* **Always Available:** Connect from any computer, anywhere, without keeping a physical Mac running at home.
* **Easy Upgrades:** Need more power? You can upgrade your Cloud Mac with one click.

<Note>
  Yes. Your iPhone is still required for iMessage and SMS forwarding. The Cloud Mac replaces your **physical Mac**, not your phone. Both must share the **exact same Apple ID**.
</Note>

## Step 2: Connect to Your Cloud Mac[​](#step-2-connect-to-your-cloud-mac "Direct link to Step 2: Connect to Your Cloud Mac")

Once your Cloud Mac is ready, HostMyApple emails you everything you need to connect: a **host (IP address), port, username, and password**. HostMyApple uses **NoMachine** as the remote desktop client - it's free, fast, and works on Windows, Mac, and Linux.

### 2.1 Download and Install NoMachine[​](#21-download-and-install-nomachine "Direct link to 2.1 Download and Install NoMachine")

<Steps>
  <Step>
    Go to [nomachine.com/download](https://www.nomachine.com/download) and download the free **NoMachine** client for your operating system (Windows / macOS / Linux).
  </Step>

  <Step>
    Run the installer and follow the prompts. After installation, NoMachine will appear in your apps.

    </Frame>
  </Step>
</Steps>

### 2.2 Add a New Connection[​](#22-add-a-new-connection "Direct link to 2.2 Add a New Connection")

<Steps>
  <Step>
    Open **NoMachine** and click **Add** (or **New connection**) in the top right.
  </Step>

  <Step>
    Fill in the **Machine address** screen using the details from your HostMyApple welcome email:

    * **Name:** anything you want (e.g. *"My Cloud Mac"*)
    * **Host:** the IP address from your email (for example, `8.30.153.52`)
    * **Port:** `4000` (this is the NoMachine default - leave it unless your email says otherwise)
    * **Protocol:** `NX`
  </Step>

  <Step>
    Click **Add** in the top right to save the connection.

    </Frame>
  </Step>
</Steps>

<Check>
  Look at the welcome email HostMyApple sent you. It lists the IP, port, username, and password for your Cloud Mac. Copy these exactly - even an extra space will cause the connection to fail.
</Check>

### 2.3 Log In to Your Cloud Mac[​](#23-log-in-to-your-cloud-mac "Direct link to 2.3 Log In to Your Cloud Mac")

<Steps>
  <Step>
    Double-click your saved connection in NoMachine. It will start connecting to your Cloud Mac.
  </Step>

  <Step>
    When prompted, enter the **Username** and **Password** from your HostMyApple email.
  </Step>

  <Step>
    (Optional) Check **Save this password in the connection file** so you don't have to type it every time.
  </Step>

  <Step>
    Click **OK**.

      <img src="https://mintcdn.com/goghl-whitelable/d0UJrCwlyc8wzaxE/images/imessage/assets/images/nomachine-login-prompt-edf2329297c7ea24d932bdd213a90fe3.png?fit=max&auto=format&n=d0UJrCwlyc8wzaxE&q=85&s=0c306b79ab7708921517e6c9a5b2c7b3" alt="NoMachine login prompt asking for username and password" width="2840" height="1544" data-path="images/imessage/assets/images/nomachine-login-prompt-edf2329297c7ea24d932bdd213a90fe3.png" />
    </Frame>
  </Step>
</Steps>

After a few seconds you'll be looking at a full **Mac desktop** running in the cloud - just like sitting in front of a real Mac.

<Check>
  Once connected, your Cloud Mac behaves exactly like a physical Mac. Everything in the [iMessage Full Setup](/imessage/getting-started) guide works the same way here - Messages app, Apple ID sign-in, SMS forwarding, and all.
</Check>

<Warning>
  * Double-check the **IP, port, username, and password** match the email exactly (no extra spaces).
  * Make sure your local internet is working - NoMachine needs an outbound connection on port 4000.
  * If you still can't reach your Mac, contact HostMyApple support; the server may still be provisioning.
</Warning>

## Step 3: Sign In With Your Apple ID[​](#step-3-sign-in-with-your-apple-id "Direct link to Step 3: Sign In With Your Apple ID")

Your Cloud Mac needs to be signed in to the **same Apple ID** as your iPhone.

<Steps>
  <Step>
    On the Cloud Mac, open the **Messages** app.
  </Step>

  <Step>
    Sign in with the **exact same Apple ID** you use on your iPhone.
  </Step>

  <Step>
    If prompted, approve the sign-in from your iPhone and enter the verification code.
  </Step>

  <Step>
    Go to **Messages → Settings → iMessage** and confirm:

    * **Enable Messages in iCloud** is checked.
    * Under "You can be reached for messages at," your **phone number** is checked.
    * Under "Start new conversations from," your **phone number** is selected (NOT your email).
    * Your email address is **unchecked**.
  </Step>
</Steps>

<Warning>
  You must always start conversations using your **phone number**, never your email. If you skip this, CRM won't know how to track your replies.
</Warning>

<Note>
  Don't forget to add your Cloud Mac to **Text Message Forwarding** on your iPhone (**Settings → Messages → Text Message Forwarding**) so green-bubble SMS messages route through it too.
</Note>

***

## Step 4: Install the iMessage Sync App[​](#step-4-install-the-imessage-sync-app "Direct link to Step 4: Install the iMessage Sync App")

From here, the setup is identical to a physical Mac:

<Steps>
  <Step>
    Follow [Step 4 of the iMessage Full Setup guide](/imessage/getting-started) to download and install the iMessage Sync app on your Cloud Mac.
  </Step>

  <Step>
    Grant **Messages** access and **Full Disk Access** when prompted.
  </Step>

  <Step>
    Paste your **Activation Code** from CRM and click **Activate Device**.
  </Step>
</Steps>

<Warning>
  The sync app must stay open for messages to work. The good news: because a Cloud Mac never sleeps, you can leave it running 24/7 without worrying about it shutting down.
</Warning>

***

## Keeping Your Cloud Mac Awake[​](#keeping-your-cloud-mac-awake "Direct link to Keeping Your Cloud Mac Awake")

Cloud Macs are always powered on, but it's still worth confirming the Mac itself won't go to sleep:

<Steps>
  <Step>
    Open **System Settings → Energy** (or Displays/Battery).
  </Step>

  <Step>
    Turn on **Prevent automatic sleeping when the display is off**.
  </Step>

  <Step>
    Turn off **Power Nap**.
  </Step>

  <Step title="Pro Tip">
    Install the free **Amphetamine** app from the Mac App Store to guarantee the Mac stays awake.
  </Step>
</Steps>

## Frequently Asked Questions[​](#frequently-asked-questions "Direct link to Frequently Asked Questions")

<AccordionGroup>
  <Accordion title="Do I need to keep my own computer on?">
    No. That's the whole point. The Cloud Mac runs in a data center, so once it's set up you can shut your own laptop and the messages keep flowing.
  </Accordion>

  <Accordion title="Can I use a Cloud Mac for multiple iMessage accounts?">
    Each Cloud Mac is tied to one Apple ID. If you manage several numbers, see the [Number Selection](/multiple-instances/number-selection) guide and plan a Cloud Mac per account.
  </Accordion>

  <Accordion title="What happens if my internet goes down?">
    The Cloud Mac uses the data center's connection, not yours. Your home or office internet dropping won't stop your messages, only the data center would, which is extremely rare.
  </Accordion>
</AccordionGroup>

***

<Note>
  With your Cloud Mac connected, head back to the [iMessage Full Setup](/imessage/getting-started) guide to finish connecting CRM and send your first test message.
</Note>
