FetchMacOS - A tool to download macOS on non-Mac platforms.

FetchMacOS - A tool to download macOS on non-Mac platforms.

 

A few months ago I was playing around with the idea of looking at Apple's new distribution method for the macOS Installer (in the A/B test that delivers either a complete app bundle, or a 7MB stub that downloads the rest separately).

 

Since it seemed to use the existing swdist distribution server, I decided to use some older code to write a client that emulates the 7MB macOS Installer and fetches the installation data from Apple's servers. It works on Linux and Windows, and is probably the closest thing to a clean copy of macOS without involving an actual Mac or the App Store.

 

This thread is just to garner some opinions on the idea, and maybe adding some improvements (such as including createinstallmedia logic to make installation drives from the data) before making a wider release.

 

FetchMacOS 1.2a (for macOS 10.14 Mojave)

http://swdist.furcode.co/bin/FetchMacOS-1.2.zip

SHA1 = ba19a1d3fdf00aa65ac7797388de27089e91d101

 

Changelog

1.2 - Support for macOS Mojave (10.14)

1.1 - Support for High Sierra (10.13)

Nice job! Congratulations!!! I think it is a great idea! Sometimes experts forget that most of us start from Windows.

[spakk]

that's a great thing

 

Edit:

It would be better to adjust the end of your Code like this installation procedure by chriss1111

the final result would be fantastic

Any download of the installer that is done not directly from app stores from a mac or even virtual machine with osx ... is illegal.

Also this tool does not require an Apple account ... so no login etc ..

 

Close for any feedback

Sorry I had to check

I have included a preview copy of the tool. Note that on Windows and Linux platforms, there is a need to decompress the packages separately.

 

Usage: fetch-macos.py [OPTIONS]

 

Options:

  -o, --output-dir TEXT  Target directory for package output.

  -c, --catalog-id TEXT  Name of catalog.

  -p, --product-id TEXT  Product ID (as seen in SoftwareUpdate).

  -l, --latest           Get latest available macOS package.

 

  --help                 Show this message and exit.

So,

I was trying to run that on Windows.

First,  .command files are not recognizable on WIN. Then I was trying to use:

python fetch-macos.py 

with both -l option or any other options but that didn't worked. It always returned Syntax Error and notice about missing product ID or message to provide -l flag. Unfortunately fetchmacos.py won't pick up ANY flags on windows, even --help didn't worked (!). Which windows version is this compatible ? Does it require something more than python to be installed ?

On screenshot i see you're using it without any flags which is even more weird..

Any tips welcome

[juniorjpdj]

You forgot to write: It's only python2 compatible ;P

For those still following along, I have updated the tool to support both beta and final builds of macOS Mojave (10.14). Yes, this does mean one can download 10.14 Developer Previews without a developer account.

I just downloaded Mojave on my Mac. Which file do i use to install tho, I've tried a couple. The attached screenshot shows the error. Thanks

[MacHackleak]

Thank you @Foxlet, i did download macOS 10.14 and install it with osinstall-legacy.mpkg on my real iMac 11.2 but when rebooted with holding option key the partition didn’t show how can I forced it to show and complete installing macOS Mojave

Hey Foxlet - long time no hear.  Thanks for the script. works great. It was mentioned on the "unsupported' forums.  Question: are you still playing with Mojave betas on unsupported macs?  And do you have system update (from preferences) working consistently?

Could you include Both of these files that way users could use the bat file to install pip and the required request and click 

 

get-pip.py

Installrequirements.bat

[W-Tiggeh]

Uh, I'm trying to use the tool and...

F:\Mac stuff\tools\FetchMacOS\>fetch-macos.py -l

  File "F:\Mac stuff\tools\FetchMacOS\fetch-macos.py", line 109
    print "You must provide a Product ID (or pass the -l flag) to continue."
                                                                           ^
SyntaxError: invalid syntax

 

I'm getting asked to use the -l flag even though I'm clearly using it...

Do I need something else?

 

EDIT: reread the topic. The program uses Python 2, and I have Python 3.6.2 installed >_<

Thank you, I know this program, but I want to use this script (FetchMacOS), because it is cross-platform.

By the way, I have on 10.14.6 program Get mac OS does not start and crashes. https://pastebin.com/hwpgGvPs

P.S.
I also found a program "Apple Multi Updates Loader [WineSkin]" that has similar functionality.
