Fails to compile Tahoe beta full installer when running on a Tahoe beta machine #184

🪲 Description

Thought I would put this here for better visibility for others. I notice mist-cli is struggling with compiling the new macOS beta installer, but not sure what the error means. FYI, I'm running this on a Tahoe beta.

It all downloads fine, hence I used --cache-downloads below to save time on the second run:

% sudo mist download installer 26 package --cache-downloads --catalog-url https://swscan.apple.com/content/catalogs/others/index-16beta-16-15-14-13-12-10.16-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz --include-betas

📋 Steps to Reproduce

  1. sudo mist download installer 26 package --catalog-url https://swscan.apple.com/content/catalogs/others/index-16beta-16-15-14-13-12-10.16-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz --include-betas

✅ Expected Behaviour

The installer should be compiled and placed in /Applications.

💻 Environment

  • mist version (mist --version): 2.1.1
  • macOS Version (sw_vers): 26.0/25A5279m
  • Hardware (system_profiler SPHardwareDataType):
    • M1

ℹ️ Additional context

  • Is this also a bug in Mist.app? Haven't tried sorry.

    FYI, this issue is specific to running mist on macOS 26 Tahoe, but not limited to just attempting to build macOS 26 Tahoe, as I have yet to get mist to build a macOS installer for any macOS version (attempted to build 13,14,15 last week, also failed)

    @wakco sadly not. I've just run the same command on my Mac running 15.6 Beta (24G5054d) and got the same error.

    (I'd love a way to just bypass the DMG creation and just run installer -tgt / -pkg /private/tmp/com.ninxsoft.mist/082-55599/InstallAssistant.pkg)

    Same error for sudo mist download installer 24G5074c application --include-betas on Sequoia. Also same error on Mist app, not just cli.

    Same error trying sudo mist download installer 15.6 iso from Sequoia 15.6, either from CLI or GUI.
    Does not seem to be linked with the downloaded image, but to a recent change on host (15.6 / 26).

    This should be fixed in #187 🚀
