Question 1

How to create a bootable USB for OS X Mavericks using macUSB?

Accepted Answer

Download the verified image from Mavericks Forever, as recommended in the README, then use macUSB's guided flow to select the source and target USB drive. Other sources may not work correctly due to compatibility issues.

Question 2

Does macUSB support creating installers for the latest macOS Sequoia?

Accepted Answer

Yes, macUSB supports macOS Sequoia (version 15) and newer, including Tahoe (26), as listed in the Supported Versions table. However, it requires a USB drive with at least 32 GB capacity for these versions.

Question 3

What's the difference between macUSB and using the 'createinstallmedia' command?

Accepted Answer

macUSB provides a visual, guided interface that handles legacy compatibility and multiple source formats, whereas 'createinstallmedia' is a terminal command limited to .app installers and can fail on older OS versions. macUSB is better for avoiding codesign errors and PowerPC scenarios.

Question 4

Can I use macUSB on an older Mac running macOS High Sierra?

Accepted Answer

No, macUSB requires macOS 14.6 Sonoma or newer as the host system, so it won't run on older versions like High Sierra. This is a strict requirement mentioned in the README under Host Computer.

Question 5

How to fix permission errors when first launching macUSB?

Accepted Answer

Enable both 'Allow in the Background' and 'Full Disk Access' for macUSB in System Settings, as detailed in the Quick Start section. Without these, helper workflows may fail during installer creation.

Question 6

Is macUSB compatible with external SSDs for installer creation?

Accepted Answer

Yes, but external drive support is disabled by default for safety. You need to enable it in Options → 'Enable external drives support' each time you launch the app, as noted in the USB Media requirements.

Question 7

What are the risks of using macUSB compared to manual methods?

Accepted Answer

macUSB reduces risks like misconfiguration and codesign errors, but it requires specific permissions and can erase all data on the USB drive, as warned. It's generally safer due to its guided flow and notarization.
