Once I found a genuine raw .dmg or .app bundle of 10.13.6 (build 17G66 – the final security-updated version), it worked perfectly. I created a bootable USB via Terminal, wiped the HDD, and did a clean install. For a 2011 MacBook Pro and a 2012 Mac mini, this OS runs surprisingly smooth. It’s the last version to support 32-bit apps, and it still runs legacy Adobe CS6 and Microsoft Office 2011 without hiccups. The APFS conversion (for SSDs) is stable, and security patches are decent for a legacy OS. Rating: ⭐⭐⭐⭐☆ (4/5) Verify the SHA-1 checksum of
