Q01 Is the hardware dedicated bare metal?

Yes—fully dedicated. We sell true 100% bare metal—no VMware/KVM-style virtualization or oversubscription underneath.

When you rent a Mac mini you control the entire machine: Apple Silicon CPU, unified memory, and NVMe SSD. Your data never shares physical hardware with another tenant—max I/O, strong isolation, native macOS efficiency.

Dedicated metal lets you use the Neural Engine and hardware accelerators without noisy-neighbor contention.
Q02 How long until my instance is ready?
  • In stock
    M4.S(16GB):Unattended automation usually finishes within 5–15 minutes after payment, then emails SSH credentials.
  • Custom
    M4.M / M4.XL:SKUs need on-site racking and networking—typically 24–72 hours. If you are in a hurry, prefer M4.S in-stock models.
Q03 What is the multi-Mac cluster service? (Thunderbolt 5)

Designed to break single-node limits, this is a physical add-on service.

If you buy two or more M4.XL instances, engineers interconnect them in the data center using Thunderbolt 5 cables rated up to 120 GB/s for direct physical links—shared storage and coordinated compute with low latency, ideal for:

  • Massive Xcode matrix builds
  • Distributed LLM fine-tuning (70B+ parameters)
  • ProRes / 3D cinematic render clusters
Adds interconnect port and labor fees, about $5–$10 / machine / month
Q04 Can I reinstall macOS or change versions?

Yes—file a ticket for on-site work. We can factory-reset or install specific macOS releases (Ventura / Sonoma / Sequoia today).

Reinstalls usually take 2–6 hours with the machine offline. Note the desired OS in the ticket and back up first.

Reinstall wipes all data—it cannot be undone. Back up before requesting.
Q05 May I install arbitrary software or change system settings?

Yes. You receive full admin rights—install apps, tune settings, toggle SIP, and more.

We do not restrict software classes as long as you follow the Terms (no illegal activity or attacks). Xcode, Docker, Homebrew, Python, and Node.js are preinstalled or quick to add via package managers.

Network and regions

Bandwidth, IP, latency, and data center topics

4 articles
Q01 Is bandwidth and the IP dedicated?

All dedicated. Each machine is physically wired to the access switch with 1 Gbps symmetric dedicated bandwidth and no data cap (within fair use).

We also assign one clean dedicated public IPv4 per device—no shared-IP port limits or mystery firewall blocks—good for public web services or private APIs.

Need more IPv4? Open a ticket; we can add addresses for a monthly fee.
Q02 Which data center regions are supported?

For lowest latency we operate owned cabinets across APAC and North America:

  • 🇸🇬
    Singapore
    ~40 ms RTT
  • 🇯🇵
    Tokyo, Japan
    ~35 ms RTT
  • 🇰🇷
    Seoul, Korea
    ~45 ms RTT
  • 🇭🇰
    Hong Kong SAR
    ~8 ms RTT
  • 🇺🇸
    US West (Silicon Valley)
    ~120 ms RTT
  • 🇺🇸
    US East (Virginia)
    ~150 ms RTT

Figures are reference RTT from major mainland China cities; your mileage varies by ISP path.

Q03 How do I test latency from my location?

Run these quick checks from your terminal:

# ping example toward the Hong Kong node
ping -c 5 hk.meshlaunch.com
ping -c 5 sg.meshlaunch.com
ping -c 5 jp.meshlaunch.com

The pricing page also includes a visual global latency map for reference.

Q04 Do you offer DDoS protection?

Our data centers include baseline DDoS mitigation for common volumetric attacks. All inbound traffic is filtered at the network edge before it reaches your machine.

For enterprise-grade scrubbing (clean pipes, protected IPs, etc.), layer Cloudflare or another CDN on top—fully compatible with us.

Remote access and management

SSH, VNC, and power management

5 articles
Q01 How do I connect with SSH?

After provisioning, the console and email list the IP and initial SSH password. From Terminal, iTerm2, or PuTTY:

# basic SSH command
ssh admin@ -p 22

On first connect type yes to confirm the host key, then paste the password. Upload your SSH public key after login and disable password auth:

# copy your local public key to the server
ssh-copy-id admin@
Q02 How do I use VNC for a GUI?
  • On Mac: Open Finder → menu bar Go → Connect to Server⌘K, then enter vnc:// and the VNC password from the console.
  • On Windows / Linux: Download RealVNC Viewer or TightVNC—enter your IP and connect.
  • Resolution: After connecting, adjust resolution and scaling in macOS System Settings → Displays.
Q03 How do I power on, shut down, or reboot?

Two ways to manage power:

  1. In-guest soft actions (preferred): After SSH or VNC login, use normal macOS commands:
    sudo reboot # reboot
    sudo shutdown -h now # shut down
  2. Console hard actions: MESHLAUNCH console → instance details → Reboot or Force power off. These commands cut/restore PDU power—hard resets; prefer soft reboots when possible.
Q04 How do I change the SSH password or port?

After SSH login you may change passwords and sshd settings freely:

# change current user password
passwd
# change SSH port (edit sshd_config)
sudo nano /etc/ssh/sshd_config
# find #Port 22 and set your port, e.g. Port 2222
sudo launchctl restart com.openssh.sshd
After changing the SSH port, open it in any firewall, test from a new terminal before closing the old session to avoid lockouts.
Q05 How do I inspect hardware specs?

Two ways to see full hardware details:

  1. Console: Sign in → My Services → Manage on the device—CPU, memory, storage, and IP summaries on the overview.
  2. CLI: Over SSH run:
system_profiler SPHardwareDataType
# or detailed memory info
sysctl hw.memsize

Billing and support

Orders, renewals, refunds, and support

4 articles
Q01 How do I view order status, renewal dates, and billing history?

In the left nav open Billing & Finance for transactions and order detail.

The instance panel highlights Next renewal date. Weekly/monthly/quarterly plans auto-generate renewal invoices and charge about three days before expiry. To stop renewals, click Cancel subscription

Daily plans bill once and end at expiry with no auto-renewal.
Q02 Can I get a refund if I cancel early?

Refund policy highlights:

  • 24-hour satisfaction window: Within 24 hours of delivery, full refunds are available for issues on our side (misconfiguration, unreachable host, etc.).
  • Pro-rated refunds: Voluntary mid-cycle cancellation refunds the unused portion (minus elapsed time and a 5% processing fee).
  • Non-refundable: Daily plans are not refundable once payment completes.

Submit all refund requests via ticket with the title "Refund request - Order #".

Q03 How do I upgrade or downgrade plans?

Bare-metal plans require swapping hardware—not an instant online resize like a VM.

Upgrades: open a ticket with requirements. We provision the new machine, migrate configs with you, and credit remaining value from the old order toward the new one. You own data movement—we provide guidance but do not auto-migrate user data.

Q04 How do I reach support?

We provide 24/7 ticket support with a first response in 15–30 minutes on average.

Console → Support & tickets → New ticket, pick a category (technical / billing / sales).
