Can I customize the machine and disks on Infinite Mac?
Updated
Yes. Infinite Mac lets you run a custom version with your choice of machine and disks, in addition to its prebuilt releases. The site describes this as running "a custom version with your choice of machine and disks," and each listed release also has its own Customize... option next to Run. So customization works at two levels: you can start from a specific release and adjust it, or build a configuration around the machine and disks you want.
What you can customize
Based on the site's description, the customizable elements are:
- Machine — the emulated Macintosh (or NeXT) model the system runs on.
- Disks — the disk images attached to that machine, which determine what software and data are available inside the emulated system.
The site also notes that an "Infinite HD" disk with representative software from the relevant era is available, so a typical setup pairs a chosen system release with that preloaded disk rather than starting from an empty machine.
Two ways to get a custom configuration
1. Customize an existing release
Every release entry in the list has a Customize... link beside Run. Use this when you want a known system version — for example System 6.0 (April 30, 1988) or NeXTStep 1.0 (September 11, 1989) — but need different hardware or extra disks than the default.
2. Start from the custom option
The site also offers a general custom path where you pick the machine and disks yourself. This is the better route when your goal is a specific configuration rather than a specific OS release.
What you can do once it's running
The site states that on some operating systems you can:
- Import and export files and disk images using drag and drop.
- Mount virtual CD-ROMs.
Because these capabilities vary by operating system, the site directs you to the welcome screen in each machine for the details that apply to that particular setup. That welcome screen is the first place to check if a drag-and-drop import or a CD-ROM mount doesn't behave as expected.
Practical notes
- Availability is version-dependent. The site says file import/export and virtual CD-ROM mounting work "on some operating systems," not all. If a feature matters to your task, confirm it on the welcome screen before relying on it.
- The disk choice defines your starting software. If you want a particular application or a clean system, that decision is made through the disk selection, not after boot.
- Embedding is separate from customizing. The site mentions you can embed instances into your own site, which is a different feature from choosing machine and disks for your own session.
Quick decision guide
| Your goal | Where to start |
|---|---|
| Run a specific OS release as-is | Pick the release, click Run |
| Same release, different machine or extra disks | Click Customize... next to that release |
| A configuration not tied to one release | Use the custom option and choose machine and disks |
| Put a running instance on your own site | Use the embed option |
If you only want to see what a given system looked like, Run is enough. If you need to reproduce a particular classic Mac setup — a specific model with specific disks — use Customize... or the custom machine-and-disk path, then check that machine's welcome screen for what import, export, and CD-ROM mounting it supports.
