Zero Terminal syntax
Drop your installer, pick a USB, and you’re done. Install Disk Creator hands the job to Apple's own createinstallmedia tool, which erases the drive and copies the installer onto it.

Back up the Mac before you boot the installer
Most clean installs start with an erased drive. Mac Backup Guru makes a complete copy of your Mac first — direct clones and incremental snapshots you can browse in Finder. The full app is free: no trial, no subscription.
Why techs rely on Install Disk Creator
Purpose-built for busy labs, repair benches, and power users who need a clean installer every time.
macOS direct from Apple
Version 2.0 fetches installers straight from Apple’s servers, so you stay current without hunting package IDs or App Store links.
Built for real deployments
Install Disk Creator has been making installer drives since 2015 and is updated whenever Apple changes the installer, most recently for the direct downloads in version 2.0.
Create a bootable installer in five steps
-
1
Connect a 16 GB+ USB drive
Use a fast USB-C SSD for the quickest write speeds. Install Disk Creator will warn you before it erases the drive.
-
2
Launch Install Disk Creator
The app auto-detects available installers and lets you download a fresh copy if you don’t have one yet.
-
3
Select your installer
Choose from existing macOS installers or pull a release such as macOS 27 Golden Gate, Tahoe or Sequoia directly from Apple inside the app.
-
4
Pick the target drive
createinstallmedia erases the drive and writes the installer. The result boots on Intel and Apple silicon Macs, for whichever of them that macOS version supports.
-
5
Boot & install
Hold Power on Apple silicon (or Option on Intel) to pick the USB volume and start reinstalling macOS.
Before you erase anything, make a complete backup with Mac Backup Guru — free Mac backup software from the same studio.

Frequently asked
Which macOS versions are supported?
Install Disk Creator builds installers for macOS 27 Golden Gate (the public beta today, and the final release the moment Apple publishes it) and macOS 26 Tahoe, plus Sequoia, Sonoma and every version back to Sierra (10.12). New releases appear as soon as Apple publishes them to its software catalog, so there is nothing to update when a new macOS ships. Older releases remain available in Apple’s catalog search.
Is the app compatible with Apple silicon?
Yes. USB installers created with Install Disk Creator boot natively on both Apple silicon and Intel Macs. The app itself is a universal binary.
Do I need to disable security or use Terminal?
No Terminal, and no security settings to change. Install Disk Creator runs Apple's own createinstallmedia tool under the hood, which needs your administrator password once to erase and write the drive.
Can I keep multiple installers on one drive?
For best results, dedicate one partition per installer. Many teams carry a small SSD and carve it into volumes named after the macOS version.
Need help or want to say thanks?
Install Disk Creator is maintained by the same one-person studio behind Mac Backup Guru and Turbo Whisper. Reach out any time—bug reports, feature requests, or success stories all help keep the app sharp.
