Hardware
Mac: M1 or later with 16 GB RAM. Windows: a basic x86_64 PC, with lower RAM requirements.
System requirements
macOS
On the Mac, Overshow requires macOS 26 (Tahoe) on Apple Silicon.
Minimum
| Component | Requirement |
|---|---|
| Chip | Apple Silicon (M1 or later) |
| RAM | 16 GB |
| Storage | 5 GB free (for models and data) |
| macOS | 26 (Tahoe) |
16 GB comfortably runs Ask, which is Mac only, alongside capture, text extraction and search.
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.
Windows
Overshow runs on basic Windows 11 PCs with an x86_64 processor. RAM requirements are lower than on Mac and vary by machine. Allow at least 5 GB free storage, with 20 GB recommended as your captured history grows.
Storage over time
The SQLite database holds screen text and derived metadata. 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
On the Mac:
- Screen Recording: required for pixel capture. Experimental builds with meeting support also use it for system audio.
- Accessibility: required to read application text. Experimental builds with meeting support also use it to recognise meeting windows.
- Microphone: needed for optional meeting audio transcription in an experimental build with meeting support.
The default build omits meeting audio and does not request microphone access.
On Windows, read-only screen capture through UI Automation needs no equivalent system grants. The installer runs as the current user.
For managed devices, confirm these can be granted under your endpoint management policy before deploying widely.
Microsoft 365
Teams transcript import and Microsoft 365 Copilot connections need the relevant Microsoft licences and your administrator's consent. We agree the details with you during the 90-day set-up. Everything consultants share works in Overshow without a Copilot licence.
