New HandyScript called installSeed.py

You may have used one of my HandyScripts to install High Sierra. The problem with these scripts was that I had to update them for every new Developer Preview. And that was a burden. Taking too much time, and that is why I converted the bash scripts to a much smarter python variant. I started to work on it back in July, but it is still ugly, and I had never used it. Not until today.

Update: installSeed.py v1.7 includes bug fixes so you better use the latest version!

Updates: installSeed.py v1.8 is now available. This update downloads the correct i18n dictionary.
installSeed.py v1.9 is now available. This update includes minor cleanups and a version number error fix.
installSeed.py v2.0 is now available. This update exits gracefully, with instructions to install pip/request module.

Anyway. We first have to make some preparations. Open a terminal window and enter:

sudo easy_install pip
sudo pip install requests

That should get you ready for installSeed.py. The output of installSeed.py is pretty much similar to that of the previous bash scripts:

Available target volumes:

[ 0 ] MackintoshHD
[ 1 ] High Sierra

Select a target volume for the boot file: 1
Seed Program Enrollment: DeveloperSeed
File: BaseSystem.chunklist already there, skipping this download.
File: InstallESDDmg.pkg already there, skipping this download.
File: InstallAssistantAuto.pkg already there, skipping this download.
File: AppleDiagnostics.chunklist already there, skipping this download.
File: InstallESDDmg.chunklist already there, skipping this download.
File: OSInstall.mpkg already there, skipping this download.
File: InstallInfo.plist already there, skipping this download.
File: RecoveryHDMetaDmg.pkg already there, skipping this download.
File: BaseSystem.dmg already there, skipping this download.
File: AppleDiagnostics.dmg already there, skipping this download.
Creating installer.pkg ...
productbuild: Wrote product to /Volumes/High Sierra/tmp/091-30125/installer.pkg
Running installer ...
Password:
installer: Package name is Install macOS High Sierra Beta
installer: Installing at base path /Volumes/High Sierra
installer: The install was successful.
Copying: InstallESDDmg.pkg to the target location ...
Copying: AppleDiagnostics.dmg to the target location ...
Copying: AppleDiagnostics.chunklist to the target location ...
Copying: BaseSystem.dmg to the target location ...
Copying: BaseSystem.chunklist to the target location ..

The good thing (for me) is that with the introduction of installSeed.py I no longer need to update the file for every new Developer Preview.

Oh. One last note. The file /Users/Shared/.SeedEnrollment.plist should be this:

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
	<dict>
		<key>SeedProgram</key>
		<string>DeveloperSeed</string>
	</dict>
</plist>

If you have a backslash in the first line, then please remove it before running installSeed.py

Have fun!

  1. Hi piker,
    Looks like it’s not working with non English setups :

  2. Hi, it’s me again, I talked too quickly. This time the script reaches the end, however, when I launch the install app, it tells me it’s damaged and cannot be used.

    • Thanks. Can you please try something. The problem is most likely that the created installer.pkg is copied to SharedResources as installESD.dmg (5.15GB) instead of installESDDmg.pkg I fixed this but I cannot commit anything right now.

      1.) remove SharedResources/installESD.dmg
      2.) rename SharedResources/installESDDmg.pkg to installESD.dmg
      3.) Try again.

      Edit: This errors should now be fixed (again) in v1.6

      • I had already tried that, though there was indeed a problem there, that’s not enough, the installer still doesn’t start. What I find weird is that if I launch OSInstall.mpkg in the raw download folder, it complains about signature being invalid. Is this normal ? I tried to remove it and let it redownload.

      • No! What is the md5 of that file?

        Edit: Yes it is. No problem here!

        Note: Relaunch the script and let it check the file sizes, so that it can replace broken files!

  3. MD5 (OSInstall.mpkg) = 7ed673fa49ab9ab70a9666e24611b207
    I redownloaded it several times already, the script doesn’t complain if I let it there.

  4. Thank You Pike!! for your effort providing the script. Just for the record I report back that script v1.6 is working OK on this side. As result a folder is created at indicated destination, included therein ‘Install macOS High Sierra Beta.app’ (checksum passes at startup).
    MD5 OSInstall.mpkg = 7ed673fa49ab9ab70a9666e24611b207
