If you're running Claude Desktop on a Late 2012 / Mid 2012 Mac via OCLP and the
Code tab crashes with "process exited with code 132", this is a known issue.
From Claude Code 2.1.109 onward, Anthropic switched to a Bun-compiled binary
that requires AVX2 instructions — which Ivy Bridge doesn't have.
I put together a fix with a one-paste terminal script that:
- Pins Claude Code to 2.1.108 (last compatible version)
- Compiles a small C launcher to bypass Electron's sandbox
- Auto-detects your Desktop version so it works after any update

Tested on iMac Late 2012, macOS Ventura via OCLP.

⚠️ WARNING:
Installing macOS Tahoe on unsupported hardware is NOT supported by the OpenCore Legacy Patcher developers. Please be aware that numerous users have attempted installation, often resulting in serious issues including hardware malfunctions and complete data loss.
Also understand that OCLP supports over 83 Mac models! Just because it "worked" on one, does not mean it will not cause major issues on your device.
NOTE: You might have seen a new piece of software called OCLP-Mod. The OCLP developers do NOT recommend using any modification of the genuine OCLP software. Keep in mind, anyone is able to make a fork of OCLP (a fork is a modification of the original project). No other software is checked and verified safe or actually working on all 83 Mac models.
In closing, please only use the genuine version of OCLP. Do not install Tahoe until a fully compatible public version of OCLP is released. Thanks!
