0.18.0

• Add --check-power option. Set this to check for AC power. Also --power-wait-limit sets a time limit to wait for power (default is 60 seconds).
• Merge in upstream changes to installinstallmacos.py. This improves download resumption.

0.17.4

• Default minimum drive space now set to 45GB, but can now be overridden with the --min-drive-space NN option.
• Fixed the --confirm option (#68).
• Improved the --help output with more recent keys.

0.17.3

• For Catalina and earlier, do OS validation only as far as the minor release. This allows for the mismatch between advertised build and DTSDKBuild (fixes Issue #53).
• Fix for when VolumeName is not Macintosh HD or any two-word name (fixes Issue #58).
• Added exit 1 code if script exists due to not successfully downloading an installer (fixes Issue #52).
• Increase munimum disk space required to 30GB, which aligns better Apple's recommendation for macOS Big Sur (see HT211238).

0.17.2

• Testing moving caffeinate to the end of the script but using a second --pidtosignal argument in startosinstall to kill caffeinate. It is not documented that --pidtosignal can be called multiple times, so this is experimental, but seems necessary on Big Sur as the "preparing upgrade" step is much longer than with previous OSs.

0.17.1

• Added --test-run option which runs everything except the startosinstall command. Useful for testing new workflows (test-erase-install.sh is therefore deleted)
• Moved the prompt for user details for Apple Silicon Macs up the script so users don't get prompted later.
• No longer checks to see if the user is an administrator as this is apparently not a criterion - only Secure Token matters.
• Bug fix: remove alignment flags in the jamfHelper commands to solve a product issue with jamfHelper on Apple Silicon Macs.

0.17.0

• New --current-user option to use the current logged in user for startosinstall authorisation on M1/DTK Macs.
• New --user option to specify a user for startosinstall authorisation on M1/DTK Macs.
• Now checks whether the specified user is an administrator.
• Now checks whether the specified user has a Secure Token.
• Now checks if the given password is correct.
• New --no-fs option for replacing the full-screen display with a utility window (for testing purposes).
• Now quits caffeinate before beginning startosinstall.
• Now correctly identifies Apple Silicon Mac Device IDs for compatibility checks.
• Now gets the installer version from /Volumes/Shared Support/com_apple_MobileAsset_MacSoftwareUpdate/com_apple_MobileAsset_MacSoftwareUpdate.xml as this is a more reliable build number than the one in Info.plist.
• Now makes more reliable version comparisons using BuildVersion by splitting the check into more sections (AABCCDDE instead of AABCCCCD).
• Script version number is now displayed when running the script. I just have to remember to update it...
• added --list-full-installers option which runs softwareupdate --list-full-installers according to the seedprogram selected.
• test-erase-install.sh script is now included in the installer package.

0.16.1

• Bug fix: --auto was being incorrectly assigned when using --os, --build etc.

0.16.0

• Added the --pkg option allowing the download of an InstallAssistant package, utilising an update alresdy made to the installinstallmacos.py fork. For Big Sur or greater only. This will probably need some more error checking.
• Added the --keep-pkg option which prevents the deletion of the package if the --move option is used to extract the package to /Applications. By default, the package will be deleted on successful extraction.
• Added the --force-curl and --no-curl options, allowing the control of whether to download installinstallmacos.py. This is in anticipation of a Makefile and package release of erase-install.sh.
• Added Makefile. This allows you to build a self-contained package containing erase-install.sh and installinstallmacos.py so that curl is not used during the run of erase-install.sh to update installinstallmacos.py. This requires munkipkg and expects to find the grahampugh fork of installinstallmacos.py in ../macadmins-scripts. Make sure you don't bundle in Greg Neagle's version of installinstallmacos.py inadvertently (or this script will fail). A package will be provided on GitHub for this and subsequent versions. Note that erase-install.sh is installed into /Library/Management/erase-install. I deliberately have not put erase-install.sh into the PATH.
• Added the --user and --stdinpass arguments when running on a Silicon Mac. Silicon Macs require an admin user and password to run startosinstall.
• Now treats 10.x or 11+ as major versions for OS comparisons.
• Fix in installinstallmacos.py for os comparisons failing where no Version is provided from the catalog.

0.15.6

• Fixed comparison of build numbers when checking the installed build is newer than the build in the downloaded installer.

0.15.5

• Version comparisons are now done based on BuildVersion instead of ProductVersion so as not to rely on Major/Minor/Point comparisons (thanks to Greg Neagle's MacSysAdmin 2020 presentation about Big Sur for tips on this).
• Code clean up using ShellCheck.
