I installed GNU/Linux Kali on my Early-2015 MacBook Pro (Mojave) by following the instructions on the Kali official website for dual boot. Linux runs fine but it boots by default. When I went to boot into Macintosh HD from the boot menu, I noticed my new Linux OS was not showing, so I held off on changing macOS to default.

The steps I followed for the installation were:

* Resize 500 GB partition to 450 GB with `diskutil apfs resizeContainer`
* Download contents of *kali-linux-2020.4-live-amd64.iso* and burn into USB drive with `dd`
* Boot into boot menu (hold down option key during power-on)
* Boot from USB
* Follow installation instructions (Guided - use the largest continuous free space)

Any ideas what could be wrong?
