Figment vs Zumac.Ai: Mac Hosting Compared

If you landed here because Zumac.Ai is showing as unavailable, there is a direct answer. At the time of review, zumac.ai marked its single Mac mini SKU as "已售罄·可登记排队" (sold out, waitlist open). Figment M-series Macs are available by configuration request at /mac-hosting/start; the exact chip, RAM and disk are confirmed in that quote. If you need a machine for a deadline, the availability gap matters more than a line-item price comparison.

Zumac.Ai also prices in Chinese Yuan (CNY), not US dollars. We do not quote a USD saving against Figment's $95/month entry price because the CNY→USD rate your card issuer applies at settlement, plus any FX fee, is what you actually pay. Compare in CNY, then run the conversion through your own payment channel before treating any gap as real.

Plans, pricing and billing terms

Zumac.Ai sells one hardware tier: a Mac mini M6, 16 GB unified memory, 256 GB SSD, in Singapore. Figment's M-series starts from $95/month; the specific chip generation at that entry price is not published and is set at quote stage, so do not assume it matches the M6.

Zumac.Ai billing tiers (source: zumac.ai):

Arithmetic in CNY: ¥999 × 3 × 0.9 = ¥2,697.30. ¥5,994 ÷ 7 ≈ ¥856.29. ¥11,988 ÷ 14 ≈ ¥856.29. ¥19,980 ÷ 24 = ¥832.50.

Zumac.Ai additionally lists a 10% service fee that is currently waived for first orders and a 3% surcharge if an invoice is requested. The two-year tier description mentions a device-shipped-after-lease option — confirm that clause in writing if it affects your decision. Tax, FX and any card fees are as stated on their checkout and your bank's settlement, not estimated here.

Figment, for comparison (physical hardware is request-based, not instant):

The $29 virtual Intel macOS will run supported Intel Mac toolchains, including Xcode 26 or earlier, and can cross-compile and sign arm64 device apps. It cannot execute ARM-only binaries, run Xcode 27, or do visionOS work — pick an M-series machine for those. It is accessed through the browser console, not inbound SSH.

Figment prices in USD. Zumac.Ai prices in CNY. These are not directly comparable without your actual settlement FX rate. If Zumac.Ai restocks and, after your bank's conversion and fees, its annual tier settles below Figment's quoted M-series price, the trade-off becomes currency risk and Singapore-only location versus the region and managed services Figment offers.

Hardware, access and toolchain fit

Zumac.Ai's M6 Mac mini is listed with a 12-core CPU, 12-core GPU, 16 GB unified memory, 256 GB SSD, Wi-Fi 7, Bluetooth 6 and three Thunderbolt 4 ports, in Singapore. Remote access is user-installed: UU Remote, Tailscale, ToDesk, RustDesk or Cloudflare Tunnel.

Figment M-series machines are Apple silicon. The specific chip generation and configuration at the $95 entry price are set at quote stage; if you need the latest-generation chip, a particular RAM size or disk size, state that in the request. Access methods, admin level and installed software image for physical M-series are confirmed at provisioning rather than assumed.

Xcode and macOS fit (source: Apple Xcode System Requirements):

Both Zumac.Ai's M6 and Figment's M-series Macs are Apple silicon and satisfy Xcode 27 and visionOS requirements. macOS Tahoe itself still supports several Intel Macs in Apple's Tahoe compatibility list; the Xcode 27 Intel limit is a separate toolchain fact. Verify the exact Xcode/macOS pair at Apple's release table before provisioning.

Reliability signals and a build-time test

Zumac.Ai does not publish a numeric uptime SLA in the source we checked; review their current service terms if a specific uptime percentage is a hard procurement requirement. Figment does not publish a numeric uptime SLA either — the Managed plans include monitoring, backups and a fixed monthly support allotment on top of the hardware.

For performance, benchmark your own project rather than quoting vendor claims. The script below stops on the first failure, so a crash is never silently counted as a fast run. Replace the scheme name with one that exists in your project — do not invent one.

#!/usr/bin/env bash
# Clean build timer — run against your own project and a real scheme.
# Usage: ./build-timer.sh /path/to/YourProject.xcodeproj YourSchemeName
set -euo pipefail

PROJECT="${1:?Argument 1: path to .xcodeproj}"
SCHEME="${2:?Argument 2: Xcode scheme name that exists in the project}"

xcodebuild -project "$PROJECT" -list   # fails fast if SCHEME is wrong

echo "=== Build timer | Host: $(hostname) | $(date -u +%FT%TZ) ==="
time xcodebuild \
  -project "$PROJECT" \
  -scheme "$SCHEME" \
  -configuration Release \
  -destination 'generic/platform=iOS' \
  clean build \
  CODE_SIGNING_ALLOWED=NO

Run it three times on each host after a warm-up build and compare medians. Independent targets inside one scheme already build in parallel, so do not assume per-target times sum linearly.

Switching from Zumac.Ai to Figment

Zumac.Ai machines are typically reached via Tailscale or similar peer-to-peer tooling the customer installs. Plan the move around that.

Before you leave Zumac.Ai

• Read the early-termination and refund clauses on quarterly or longer commitments on Zumac.Ai's own terms page before you cancel.
• Inventory running services and scheduled tasks (launchctl list, crontab -l, any login items).
• Export signing certificates with their private keys as encrypted .p12 files from Keychain Access, protected by a strong passphrase. Do not dump the whole shell environment to a text file; it may contain tokens.
• Copy provisioning profile files from ~/Library/MobileDevice/Provisioning Profiles/*.mobileprovision.
• Write down required secret names only; restore their values on the new machine through your team's secret manager.
• Save CI configuration (Fastfile, .github/workflows/, Xcode Cloud workflows or equivalent) and note any customer-controlled allowlists that currently include the Zumac.Ai outbound IP.

On the new Figment machine

• Request configuration at /mac-hosting/start: chip generation preference, RAM, disk, region, and whether you want the Managed Build Mac wrapper.
• Confirm the installed macOS version matches the Xcode release you need before installing Xcode.
• Import .p12 certificates into a dedicated, non-default keychain created for CI; add that keychain to the search list and restore the previous list on teardown with a trap. Place provisioning profiles back under ~/Library/MobileDevice/Provisioning Profiles/.
• Restore secrets through your secret manager, not shell history.
• Clone your repository and run the timing script above with your actual scheme.
• Update only the allowlists you control — CI runner IPs on your artifact store, firewall rules, internal services. There is no public App Store Connect or TestFlight inbound IP allowlist to maintain.

After migration

• Keep the Zumac.Ai machine running until at least one full release cycle has succeeded on Figment.
• Then cancel, reading the refund/prorated-term clause on their terms page before the next billing date.

Which Figment plan fits

When Zumac.Ai is unavailable, a machine you cannot rent is not a comparison. When it restocks, do the FX math on your own card statement before treating any difference as a saving, and weigh Singapore-only versus the region Figment can offer you. Start a configuration at /mac-hosting/start or review plans at /mac-hosting.
