I tested on a MacBookPro9,2 (13-Inch, Mid-2012).

0. I clean installed from the 21.04 release image (http://releases.ubuntu.com/21.04/ubuntu-21.04-desktop-amd64.iso). FWIW I made my usual choices

 - Minimal installation

 - Download updates…
 - Install third-party software…

 - Erase disk and install Ubuntu

1. Restarting after the install, the computer showed a gray screen and never booted up as per the original issue.

2. I booted again from the install media, opened the live session, did the workaround steps from #14 and booted into the Ubuntu 21.04 installation.

3. I enabled -proposed and ran `sudo apt install shim-signed` to upgrade that package to version 1.47+15.4-0ubuntu2.

4. I tested booting several times – cold boots, restarts and holding the option key to load the Mac boot menu – and the computer always boots normally.

5. FWIW I also then ran `sudo apt full-upgrade` to install the other available updates and the computer had continued to boot normally.
