Hello. I just purchased a few Raspberry Pi's (3 Model B V1.2), and I have consistently encountered the rainbow screen of death at every boot (Red LED is solid, and no lightning-bolt indicator is seen). From other blog posts, I've read that this is reflective of the SD card not being formatted or read correctly .I have checked my power supply (2.4 Amps) and tried installing the latest Noobs and Raspbian images directly from the official website after formatting my card (32 GB) using the official SD formatting tool (I am using a Mac) multiple times.
What am I missing? Any advice is appreciated.
