Cannot Install macOS on PSP — Architecture, Resources, Drivers, Legal All Incompatible

Absolutely not. The PSP (MIPS/Allegrex CPU, 32–64 MB RAM, 480×272 screen, proprietary OS) is fundamentally incompatible with macOS (x86_64/ARM64, 8 GB+ RAM, Metal GPU, Darwin kernel, Apple-signed boot chain).

Why It's Impossible

• Architecture Mismatch: MIPS vs. x86/ARM — macOS binaries won't execute.
• Resource Gap: macOS needs ~2 GB RAM minimum; PSP has 32–64 MB.
• Driver/Subsystem Absence: No GPU, storage, USB, Wi-Fi, audio, or power drivers for macOS on PSP hardware.
• Legal: macOS license forbids installation on non-Apple hardware.

What You Can Do

• Mac Emulators on PSP: Basilisk II (Mac OS 7/8), Mini vMac (System 7) — run classic Mac OS (pre-OS X) at usable speeds.
• Linux on PSP: uClinux / µClinux ports exist (command-line only, experimental).
• Custom Firmware: Run homebrew, emulators (NES, SNES, GBA, PS1), ISOs — but not macOS.

Enjoy retro Mac classics on PSP; leave macOS to actual Macs.
