Start with the workload, then choose the configuration

Which cloud Mac can reliably handle your workload?

Don’t choose by chip name alone. Check concurrent build jobs, project dependencies, unified memory peaks, and the data that must stay on the node before choosing a rental term and node. All three configurations are dedicated physical Macs: every order gets its own Mac mini physical node, with compute, memory, and local storage not shared with other customers.

3 plans Fixed in-stock configurations
6 Physical nodes available
4 Daily, weekly, monthly, and quarterly terms
DECISION BOARD OM-CFG-03

Record real peak usage in all four decision areas instead of estimating from averages.

Build concurrency How many jobs run at once

Check whether local development, testing, archiving, and CI queues overlap.

Project scale Dependencies and module count

Account for indexing, linking, dependency resolution, and persistent workspace overhead.

Memory peak Measure the peak, not idle usage

Xcode, simulators, browsers, and model processes all share unified memory.

Local data Source, caches, and artifacts

Reserve space for DerivedData, dependency caches, model weights, and archives.

All plans use physical, non-virtualized Macs Starting at $19.1/day
Hardware and pricing baseline

Compare all three configurations in one table.

All prices are charged in US dollars (USD). Daily rental suits short validation tasks, weekly rental suits focused iteration, and monthly or quarterly rental is better for persistent build nodes. Before choosing a term, confirm the memory and local SSD capacity your workload requires.

All three configurations are available in Singapore, Japan (Tokyo), South Korea (Seoul), Hong Kong, the US East Coast, and the US West Coast. Availability is reported in real time by the console. Choose the node closest to your code repository, team, and target test users.

Choose by upgrade signals

From running workloads to stable parallelism.

These recommendations are not a substitute for measuring your application; they provide an actionable starting point. Choose a plan that covers your current peak. Upgrade when memory pressure, cache usage, or concurrent queues consistently approach the limit.

CFG / 16

Light builds: OnceMac M4 16

Best for solo remote development, small iOS projects, command-line testing, short-term release validation, and workloads with one primary build job at a time.

Build workloads

Project size is only the surface; resource contention determines the plan.

Fixed compile times cannot be compared across projects: dependency versions, warm or cold caches, signing steps, test scope, network downloads, and concurrency settings all affect results. A more reliable approach is to record peak CPU, memory, cache, and queue usage across a complete pipeline run.

WORKLOAD MAP

Checkpoints and recommended starting points for three project types

01 · Small iOS project

One primary app with few dependencies and targets

First verify that clean builds, incremental builds, unit tests, and archives complete reliably in the same environment.

CPU Track sustained utilization during compilation and linking
Memory Record the combined peak of Xcode, simulators, and test processes
Cache Check remaining space after retaining dependencies and DerivedData
Concurrency Usually begin by validating one primary job
Recommended starting point OnceMac M4 16

M4, 16GB unified memory, and a 256GB SSD provide a practical baseline for repeatable testing.

02 · Medium multi-module project

Multiple internal modules, package dependencies, and test targets

Indexing, dependency resolution, testing, and archiving are more likely to overlap. Monitor memory pressure and cache growth instead of checking only whether one build finishes.

CPU Check whether compilation jobs and test processes compete continuously
Memory Account for indexing, simulators, and browsers remaining resident together
Cache Separate reusable caches from artifacts that can be cleaned periodically
Concurrency Assess whether development builds and CI jobs run simultaneously
Recommended starting point OnceMac M4 24

M4, 24GB unified memory, and a 512GB SSD leave more practical headroom for multitasking development.

03 · Large workspace

Many targets, parallel tests, and continuous build queues

Measure builds, tests, archives, log processing, and other persistent tasks as one workload, while reserving capacity for burst queues.

CPU Observe queue throughput and wait time under sustained load
Memory Check the combined peak of multiple toolchains and test processes
Cache Plan the lifecycle of source, dependencies, archives, and logs
Concurrency Simulate overlapping jobs using the real number of runners
Recommended starting point OnceMac M4 Pro 64

M4 Pro, 64GB unified memory, and a 2TB SSD are better suited to high concurrency and large local datasets.

MLX and unified memory

Loading a model is not the same as having enough room to experiment.

MLX can use Apple Silicon unified memory directly, but available capacity must also cover macOS, Python environments, the model runtime, context caches, data preprocessing, and other development tools. Choose a configuration based on the stable peak after the model loads, not just the model file size.

Quantization, context length, batch size, model architecture, and concurrent requests all affect memory usage and inference performance. The same model may need very different headroom under different parameters, so we do not promise a fixed speed or a fixed list of runnable models.

Resident model Record unified memory usage after the weights finish loading
Data preprocessing Include conversion, tokenization, and image or audio processing in the peak
Concurrent experiments Check the pressure from multiple processes, batches, or contexts running at once
UNIFIED MEMORY Reserve headroom for peak usage
16GB Environment validation and small-scale inference

Suitable for installing MLX, validating scripts, checking dependencies, and running experiments with lower memory requirements. If the model runs alongside Xcode or other tools, measure actual pressure first.

24GB Development tools and experiments in parallel

Provides more room for preprocessing, development environments, and inference with moderate memory needs. Re-test based on model quantization and context settings.

64GB Higher-memory models and multi-process workloads

Best for larger resident models, highly concurrent builds, or inference running alongside development tools. It does not mean every model will run with every parameter set.

Storage expansion

Estimate source, caches, artifacts, and models separately.

Base SSD capacity is fixed by configuration: OnceMac M4 16 includes 256GB; OnceMac M4 24 includes 512GB; and OnceMac M4 Pro 64 includes 2TB. Expansion fees are added to the selected configuration and rental term, making them suitable for workloads that retain more build caches, archives, test assets, or model weights.

Daily, weekly, monthly, and quarterly pricing for base SSD and storage expansion
Storage option Best for Daily Weekly Monthly Quarterly
Base SSD Included in the selected configuration price: 256GB, 512GB, or 2TB Included Included Included Included
+1TB SSD For additional dependency caches, archives, assets, and medium-sized models $2.1 $5.8 $10.7 $29.1
+2TB SSD For larger datasets, long-term build caches, and retaining artifacts from multiple versions $4.2 $11.6 $21.4 $58.2
01 · Source and dependencies

Calculate the complete workspace.

Beyond the Git workspace, include package-manager caches, binary dependencies, multiple branch copies, and temporary export directories.

02 · Builds and archives

Leave room for DerivedData.

Multiple Xcode versions, Schemes, test artifacts, and archives continue to grow. Establish cleanup rules instead of relying on manual space management.

03 · Models and data

Separate weights, caches, and datasets.

Model file size does not represent runtime memory, but it directly uses SSD space. Download caches and converted copies must also be counted separately.

Final check before ordering

Write down all five items before submitting your configuration.

A complete choice combines the chip, unified memory, SSD, node, and rental term. If several team members will use the machine, have the engineers running the builds or experiments confirm peak usage first instead of choosing by procurement label alone.

  1. 01

    Chip

    Start with M4 for light and everyday development; prioritize M4 Pro for large workspaces, highly concurrent workloads, or high-memory experiments.

  2. 02

    Unified memory

    Record the peak while Xcode, simulators, browsers, runners, or models run together, then choose 16GB, 24GB, or 64GB.

  3. 03

    Storage

    Add up source, dependencies, DerivedData, archives, logs, models, and datasets, then decide whether the base SSD needs an additional 1TB or 2TB.

  4. 04

    Node

    Choose among Singapore, Japan (Tokyo), South Korea (Seoul), Hong Kong, the US East Coast, and the US West Coast based on proximity to your team, repository, or test users.

  5. 05

    Rental term

    Choose daily or weekly for short-term validation; consider monthly or quarterly for ongoing development, CI/CD, and long-running experiments. All amounts are charged in US dollars.

Consistent payment terms.

Only USDT-TRC20 and Visa / Mastercard / Amex (via Stripe) are supported. All charges are in US dollars (USD). Available payment gateways and configuration availability are reported in real time by the console.

Dedicated physical Mac mini nodes

Use your five conclusions to complete the configuration.

Choose the chip, memory, and storage from three dedicated physical Mac configurations, then select one of six nodes and a daily, weekly, monthly, or quarterly term. For specialized workloads, send the team your concurrency, peak memory, and data volume first.
