Hardware and platform guidance for stable daily use

Hardware, operating system, and storage requirements for running Overshow on macOS.

macOS only for v1.0 (Apple Silicon)Minimum specsRecommended specsDisk and retention

What the laptop needs

8 GB
RAM minimum

Usable, but local AI and capture compete for memory on heavier workloads.

16 GB
RAM recommended

Comfortable with continuous capture, transcription, and on-device chat.

20 GB
Free storage recommended

Leaves room for the local models and the SQLite database as retention grows.

Before you install

Three things to check

Hardware

Apple Silicon required for the full on-device AI stack, including a local language model.

Operating system

macOS 26 (Tahoe) or later, Apple Silicon only.

Permissions

Screen recording is required. Microphone is needed only for audio transcription. Accessibility is optional and improves window detection.

Hardware looks right?

Install on one laptop and try it for a week.

System requirements

Minimum and recommended specifications

System requirements

macOS

v1.0 requires macOS 26 (Tahoe) on Apple Silicon. This is the only supported platform for v1.

Minimum

Component Requirement
Chip Apple Silicon (M1 or later)
RAM 8 GB
Storage 5 GB free (for models and data)
macOS 26 (Tahoe)

With 8 GB RAM the laptop will feel constrained when on-device chat and capture run together. Transcription, OCR, and search remain comfortable.

Recommended

Component Requirement
Chip Apple M2, M3, or M4
RAM 16 GB or more
Storage 20 GB or more free
macOS 26 (Tahoe)

The on-device language model is optimised for Apple Silicon.

Storage over time

The SQLite database holds OCR text, transcriptions, and embeddings. Expect roughly 500 MB per month for database growth on normal use, bounded by configurable retention. No screen images or video files are persisted, so disk use tracks text and metadata only. Keep 20 GB free if you want headroom for models and caches.

Permissions

  • Screen recording: required.
  • Microphone: required only if you enable audio transcription.
  • Accessibility: optional. Improves window and context detection on macOS.

For managed devices, confirm these can be granted under your endpoint management policy before deploying widely.
