LM Studio Mac stability worries grow

A Reddit user reports severe LM Studio instability on a 48GB Apple Silicon Mac during long OpenHands sessions, including Metal memory failures, degraded tool-calling, model looping, and occasional full reboots across MLX and GGUF setups. The complaint lines up with LM Studio’s role as a local inference app for macOS and with at least one recent bug report pointing to higher MLX memory usage in newer versions.

// ANALYSIS

This looks less like one bad prompt and more like a real pressure point in the Apple Silicon local-inference stack, especially when agent workloads keep long contexts and tools alive for hours.

–LM Studio explicitly targets local model execution on macOS and supports Apple MLX, so failures here hit one of its core use cases
–The Reddit report spans multiple model families and formats, which weakens the case that this is just a single broken checkpoint
–A February 2026 LM Studio bug report described 0.4.2 using more memory than 0.4.1 on macOS with MLX, suggesting at least some recent regressions are plausible
–OpenHands-style sessions are harsher than simple chat because long context, tool calls, and sustained generation expose KV-cache and Metal memory edge cases fast
–Even if smaller models reduce crashes, that is a workaround, not a fix, and local AI users care because reliability is what makes agent workflows usable
