erase-install's Introduction

Currently most active projects 🧑🏼‍💻

My most popular and demanding project is 🗂️ erase-install, a zsh script for upgrading, reinstalling and erasing macOS. This was updated significantly in 2022 to use mist-cli and swiftDialog, and has to keep pace with changes to those projects as well as changes to macOS itself.

My other most used project is JamfUploader. This is a collection of python processors for use with AutoPkg which is the dominant method for integrating AutoPkg with Jamf Pro. 2023 saw significant updates to the JamfPackageUploader processor, after Jamf provided a new version of their Cloud Distribution Service (JCDS 2.0) and provided an official package upload API endpoint/method for the first time.

These processors are also mirrored in my AutoPkg recipes repo, grahampugh-recipes, along with a large collection of recipes and examples of how to write .jamf recipes.

Other notable projects 📝

For those interested in an easy script for setting up AutoPkg on a fresh machine, including (optionally) configuring JamfUploader, check out AutoPkgSetup.

If you need a signed package to add to your MDM to install Rosetta 2 at enrollment, check out Rosetta-2-install.

If you want a tool that is somewhat like a lightweight Nudge, which doesn't require any configuration changes with time, check out Nice Updater 2. Note that this is a highly altered fork of the original project by Ryan Ball, which you can check out at ryangball/nice-updater.

If you need to convert PLIST files to YAML, or vice versa, check out plist-yaml-plist.

Deprecations ☠️

The projects based on python-jss that I inherited from Shea Craig, namely JSSImporter, Spruce, jss_helper, JSSRecipeCreator, and python-jss itself, are all now deprecated. You can still find the code in the JSSImporter organisation.

If macOS is 10.4 and above then there is no need for the switch "--applicationpath"

startosinstall Arg Suggestions & Notes

I am working on a script to be used with macOS refurbishment, and your startosinstall argument was an invaluable reference. I wanted to share back the related work that I did.

Instead of using OS version checks in my code to determine supported startosinstall arguments, I wanted to use the output of startosinstall --usage. Sadly, I found that startosinstall --usage can take a VERY long time so I went about finding another similar solution. I landed on grepping the binary contents to check for supported arguments. This feels a bit unconventional but its effective and MUCH faster than loading the --usage.

Checking the Darwin major version, as erase-install is doing, is a perfectly valid solution but I thought this alternate solution may interest you.

Also, while I was working on this, I noticed that you have CORRECT code but an INCORRECT comment at

erase-install/erase-install.sh

Line 1101 in 0e5c38b

# macOS 11 (Darwin 20) and above requires the --allowremoval option

This comment is incorrect, although the code correctly only adds the --allowremoval argument on macOS 10.15 Catalina. You can see my comments in the included code for more info on this argument (which also reference your blog post about it).

And lastly, I see that your code in erase-install only sets --stdinpass and --user when running on Apple Silicon. This does not sync with my findings during my own testing. I found that Big Sur requires --stdinpass or --passprompt when on Intel Macs as well. I believe an error is returned stating that specifying form of authentication is required. And if not running as an admin user the --user argument is required to specify which admin to authenticate with (or else it will try to authenticate with the currently running non-admin and fail). I can double-check these findings though since most of my testing was on a non-admin account as well as a T2 Mac which may have had its own requirements separate from non-T2 Intel Macs.

Here is my startosinstall code with the intelligent argument selection based around grepping the startosinstall binary:

startosinstall_args=( '--nointeraction' ) # The "nointeraction" argument is undocumented, but is supported on ALL versions of "startosinstall" (which is OS X 10.11 El Capitan and newer).

# NOTE: Instead of using version checks to determine supported "startosinstall" arguments, I wanted to use the output of "startosinstall --usage" instead.
# But, I found that "startosinstall --usage" can take a VERY long time. Grepping the binary contents to check for supported arguments is unconventional but effective and MUCH faster!
# The part of the binary contents that have the actual usage strings all end with a ", " so it is included in the greps to not match other error messages, etc.
# To retrieve/verify all the strings referencing arguments within a "startosinstall" binary, run: strings "${path_to_installer_app}/Contents/Resources/startosinstall" | grep -e '--'

add option to call jamf policy

I've got some locations that are behind proxies and restricted firewalls and I tried to run the 0.11.1 script on a machine there, and basically it can't get out to pull the swscan URLs to pull the OS versions. However, we have the OS in a DMG on our jamf distribution points and a policy on a custom trigger.

If the script 1) can't find the installer locally 2) wasn't able to download directly from apple, then can it try a 3rd attempt to call a policy?

We'd need multiple policies I guess depending on the OS installer to cache, but still would be doable.

Add a breakout if an error is detected

In testing on an iMac with a Fusion Drive (already converted to APFS, when it went to do the erase, it resulted in errors in ~/Library/Logs/JAMF/selfservice_debug.log

Fetch Full Installer doesn't work on Big Sur

The flag --fetch-full-installer doesn't work when running this script in Big Sur.

The logic in line 1049 expects os_minor_version to be greater than or equal to 15 (Catalina) but the code to get that version has a hardcoded "10" it replaces, so line 986 actually returns "11" (and not the actual minor version like 2 for 11.2.3). Either way 11 or 2 are both lesser than 15, so FFI is not attempted.

Line 1049: if [[ $ffi && $os_minor_version -ge 15 ]]; then

Line 986: os_minor_version=$( echo "$os_version" | sed 's|^10\.||' | sed 's|\..*||' )

As explained by Scripting OSX here there are multiple ways to fix this. Simplest being just adding a 'os_major_version' and comparing that first.

majorVersion=$(sw_vers -productVersion | awk -F. '{ print $1; }')
minorVersion=$(sw_vers -productVersion | awk -F. '{ print $2; }')

if [[ $majorVersion -ge 11 || $minorVersion -ge 14 ]]; then
  echo "Mojave or higher"
fi

OS security patch update issue

Hi ,

I am looking forward to updating the current OS either Mojave, Catalina , big sur, as up to date..........

when I'm trying this upgrading the OS and with download full installed.

if not wrong is this only to get download the full installer OS.

is not having the option to do security patch update /install.

attaching file if its full installed its working fine. if its security patch update is not the right one.
can you pls suggest?

installer_app_name undefined?

Install macOS High Sierra.app is in the Applications folder, the script finds the App starts Jamf Helper with the full screen message but doesn't execute the script due to and undefined path to the installer?

Valid installer found. No need to download.
WARNING! Running /Applications/ with eraseinstall option

So it doesn't see the install app in the /Applications folder or it is not being phrased

Incorrect exit code on line 635?

Lines 633 to 635; as this condition of the if statement occurs when a disk image hasn't been downloaded by installinstallmacos, shouldn't it technically be considered an error and therefore error out with an exit code of > 0 on line 635?

Basically, I'm seeing a few macOS upgrade policies that use erase-install finish with a "Complete" status, rather than "Failed" status, when the Mac doesn't upgrade due to a failed installer.app download.

Download getting failed in high sierra 13.6

Find the image as I used the value bit got failed

Error: failed to authorize for installation. Provide a password with --stdinpass or --passprompt.

Environment: M1 MacBook Pro running macOS 11.1

Download of the OS completes, but it looks like maybe the "--erase" switch requires a password now, even if run as an administrator.

This is the error returned:
Error: failed to authorize for installation. Provide a password with --stdinpass or --passprompt.

Usage for startosinstall under 11.2:

Usage: startosinstall

ERROR! The startosinstall binary requires a user to be logged in.

Not sure if this is an issue with this software or something new that Apple introduced, but when we run this via SSH we're now getting:

Remove `installinstallmacos` after/before script runs

Hey. I've experienced an issue involving a machine that connected to a VPN that restricted access to Github. This restriction essentially prohibited the erase-install script from downloading the installinstallmacos.py script, and in it's place, was a blank file. From that point onward, every time the erase-install script was run, even when not connected to the restrictive VPN, the blank file persisted, and the script failed. I needed to manually delete the installinstallmacos.py script, at which point the erase-install script correctly downloaded the installinstallmacos.py script, and everything worked as it should.

Tl;dr; can we delete the installinstallmacos script before/after each run?

OS Version selection no longer "automatic"

From 0.16b2 onwards, if I run the script through a Jamf policy (or by hand), it no longer selects the OS Version to download in installinstallosx.py automatically. The script is waiting on an input from the user on which Version to select, so it hangs indefinitely.
Tested on a stock macOS 11. 0.16b1 does work, though.

Bye, Fridolin.

New caffeinate feature hangs script

I can provide any additional details as needed.

Script not downloading OS

Unsure of where to look for what's causing this issue, but I'm seeing a large number of devices, run the script cache the installer but never actually download anything. Their logs look like the following:

find_existing_installer check OS

When running with the --fetch-full-installer and specifying the --version, if an installer like Install macOS Catalina.app already exists it will proceed with validating and running through the rest of the options.

The problem though is if I specify the --version to 11.2.3, if I already happen to have a 10.15.7 installer in the Applications folder, it will use that and not even attempt to download 11.2.3.

(--overwrite) macOS installer not appearing in Applications

Using Autopkg and Jamf Pro for testing.

I see the script complete and can verify that the sparse image has been downloaded however it does not seem to move the .app into the proper folder.

I will continue trying with --move as well but curious if I am missing something. Thank you!

Restart fails with "The operation couldn't be completed. (Cocoa error 132001.)

Testing erase-install from the self-service app and I receive the error:
Restart fails with "The operation couldn't be completed. (Cocoa error 132001.)

I believe this is related to quitting the Self Service app. If I wait before clicking OK I see the following message on the screen:

Your Mac hasn't restarted because "Self Service" failed to quit. To continue restarting, quit "Self Service".

Clicking OK on the Cocoa message and clicking Try Again on the "hasn't restarted" message results in the machine restarting with the installer.

OS install issue

Hi Getting error while initiate the OS install.

sudo bash erase-install.sh --erase —confirm --version=10.15.7 --overwrite
sudo bash erase-install.sh

tried all getting some error in "installinstallmacos.py"

erase-install doesn't seem to install

Hey Graham, I'm playing around with erase-install and running into a weird issue where it doesn't seem to actually install the OS (trying to upgrade a VM running 10.15.7 to 11.0.1). The Script runs fine from Jamf initially when used to cache the installer onto the system but then when running a followup policy with the --reinstall flag no JamfHelper and no install proceeded :(.

This is the output that I get from running the script (identical whether I run via a Self Service Policy or via the script on the VM itself.

Add progress indicator?

Is it possible to add a progress indicator when downloading by chance so users can feel more reassured that something is happening?

Extra packages function fails when there are no packages in the default directory

Tried the script on a machine running 10.13.6, with --erase and --os=10.13.6

OS downloaded fine, then it looks for extra packages at $workdir (default in my case)/extras/*.pkg, but then the script fails with "Error: specified package could not be found".

Interestingly, I am actually not trying to include any extra packages. The extras directory doesn't even exist at all as a matter of fact. It should be returning an empty list; However it seems to be returning enough back to the MacOS Installer that it tries to find them and then chokes.

Erase to the same OS results in build valid check error? (10.15)

Hey Graham,

I'm attempting to erase a workstation running 10.15.7 to the same OS (10.15.x) via the param --os=10.15. Running the command as below the following output is received where it stops at '[check_installer_is_valid]' because the build number no longer matches.

sudo /Library/Management/erase-install/erase-install.sh --erase --os=10.15 --test-run

Add power source check, move space check forward

Hi number of proactive requests

issue 1: Battery percentage, adapter connected or not, and disk space check, and add the retrying an option

kindly make it before getting download the OS.

last minute saying your mac not having sufficient space or system shutdown sue to poser failur.

because downloading the OS it pain around 8 to 12 GB of data

issue 2

pls add one more option for the OS validation even --overwrite to avoid the spending download and internet.

for example, downloaded the OS in as its path and rerunning the same command it should take the existing OS because it downloaded as success without any issue

is that you have validated and kept the file and use it again instant of --0verrwide

issue 3: once the specification checked it should retry because selected the --0verrwide again I need to spend time and the internet to get it to download.
getting failed due to space issue there is no option for the retry and validate the space again.

pls, advise if it wrong.

Signature verification of the os installer

If we install using installinstallmacos.py, there is a possibility that an incorrect OS will be installed, for example, if the catalog has been modified.
This is why we believe that we should check the signature of the binary and application.

This is the same idea as Gatekeeper for macOS.

Is it possible to add this feature?

Basic user confirmation prompt for non-Jamf devices

It would be great to have a --confirm option that works for non-Jamf devices to do some basic user confirmation prior to proceeding with an erase/install.

Installation fails to proceed if Volume Name contains no spaces.

The script doesn't work if the disk's name doesn't contain a space. E.g. it works on 'test
1' but not on 'test1'. The same also happens with the 'erase-install.sh' script from your
website.

It downloads the installer without any problems then there's shortly a screen displayed
with the info that the OS is being upgraded and then it goes back to the normal OS desktop
with the user still logged in.

If I run the script from the command line then I get the following error message:

Error: could not find target...

and then:

[erase-install] 'jamfHelper' ended

I've tried this with different disk names and both with encrypted and unencrypted disks.
The computer is running the latest version of High Sierra with all updates applied, it's a
13" MacBook Pro from September 2015.
Do you have an idea what's going wrong?

Which version of Install macOS High Sierra.app to download?

There are currently three different macOS High Sierra installers available, due to multiple forked builds. This makes life very difficult for this script to determine which one to get. I decided to add some logic to the script to attempt to grab the oldest one, which will cover the most Macs.

But perhaps I should check for the version currently installed on this computer and download this if available, as you really need to run the startosinstall using an installer of the same version as is currently installed.

confirm not working on 0.17.3

--confirm is presenting the dialog box, but clicking Yes or Cancel both result in a failure:

[erase-install] User FAILED to confirm erase/install

--os=X.Y not respected

I've been trying to update the scripts to the current versions, and it seems it's not respecting --os=10.14 nor --version=10.14.6

Error No such file or directory

Awesome script, just an FYI when testing today.

Doesn't do an erase install, stops at

./erase-install.sh: line 294: /Contents/Resources/startosinstall: No such file or directory

Thinking there is an issue with path stated in the variable, but I am unsure...

"$installmacOSApp/Contents/Resources/startosinstall" --applicationpath "$installmacOSApp" --eraseinstall --agreetolicense --nointeraction

Looks like upgrading using `startosinstall --eraseinstall` is still a no-no

This script should probably prevent the --eraseinstall option running an installer different to the current installed version.

When running with the --version=10.14 option on a MBP running macOS 10.13.6, this resulted in a failed install and a non-bootable system volume.

Need to test this more.

Support for VMs?

Is it possible to get this to work for VMware Fusion VM's? Here is my current output. It seems as though Unsupported Board ID is the issue.

Failing to Detect Big Sur 11.2.1 (20D74)

This looks like it is potentially an issue with installinstallmacos.py. However, I noticed that erase-install.sh appears to have the --fetch-full-installer flag disabled.

Inadvertently saving two copies of the installer?

I'm trying to use the erase-install script through Jamf to download and cache a copy of the Big Sur installer. I'm using the --move argument when calling the script, and it works as it should -- in the end, I have a copy of the Install macOS Big Sur.app in the Applications folder. However, while the installer app is about 12GB in size, I've noticed that my available hard drive space has decreased by closer to 25GB. It seems to me like another copy of the installer is being left somewhere, but I'm not sure where -- I looked in /Library/Management/erase-install, and am only finding the .py script in there. Am I doing something wrong, or is there another way to ensure that the .app in the Applications folder is the only one left on the machine? (We have some MacBooks with smaller drives, and I fear that the extra space being taken up might be enough to dip them below the free space required during the Big Sur install.)

UPDATE: I've done some more testing, and I'm wondering if this might be related to APFS. On a test computer, before running erase-install --move I had 66.2GB of free space. After running it, it's down to 42.3GB. But running a disk map tool like GrandPerspective only shows one file that's 12GB in size, the installer .app in Applications. Could what I'm seeing be related to the APFS snapshot of the temporary files the script downloaded?

pls make it will be helpful full to.

Feature Request - Prompt for which version?

I had a couple feature requests, I'm not sure of the effort required...

I saw on the wiki that it's possible to prompt for user info on the m1s, is it possible to prompt for OS as well so the techs can choose which version (eliminate the need of maintaining multiple versions of the policy for different OS options)
If a curl command fails (some of our locations restrict it while others do not), is it possible that if it times out that it can then call a JAMF Policy to cache the installer?
