[SOLVED] fetch-macos.py 10.15 10.14 catalina

fetch-macos.py utility requires the version of MacOS to be specified within the mysterious format of "Product ID (as seen in SoftwareUpdate)". Hmm... it took me a while to discover those Product IDs.

They are as follows (you need to use string like "001-57224" as an argument to -p option):

# ProductID Version Build Post Date Title 1 001-15219 10.15.5 19F2200 2020-06-15 macOS Catalina

11 061-26589 10.14.6 18G103 2019-10-14 macOS Mojave

13 071-72781 11.5.1 20G80 2021-07-26 macOS Big Sur
14 001-57224 10.15.7 19H4 2020-10-27 macOS Catalina
15 041-90855 10.13.5 17F66a 2019-10-23 Install macOS High Sierra Beta
16 061-26578 10.14.5 18F2059 2019-10-14 macOS Mojave
17 071-78704 11.5.2 20G95 2021-08-18 macOS Big Sur
18 001-36735 10.15.6 19G2006 2020-08-06 macOS Catalina

So the final version of the wanted command could be:
$ python3 fetch-macos.py -p 001-57224
P.S. You're also might be interested in installinstallmacos.py instead of fetch-macos.py.
