Potential problem & fix
Couldn’t finish downloading macOS pkg through the tool. (Encountered it myself.) To fix this:
- Copy the link for the selected MacOS inside the OpenCore Legacy Patcher tool.
- Paste it into Motrix downloader, download from it. It is free and open source, no worries.
- When it is downloaded, locate it using the OpenCore Legacy Patcher tool to continue to install.
Tips:
-
Download could take very long. It took me about an hour and a half. Just be patient.
-
After the install, make sure you have Post-Install installation as well, OpenCore Legacy Patcher should automatically run it.
-
Install the OpenCore to your booting hard disk, so it doesn’t rely on your USB to boot.
I am now using a MacBook Air 2015 with SonomaOS while writing this article.
