System requirements​

Mnemosyne OS runs its engines on your machine — that's the whole point. The hardware you give it decides how much of the OS wakes up.

  • Memory (RAM) — 8 GB minimum: enough to run the OS in a simple, degraded mode. 32 GB recommended to run every engine at full capacity.
  • Disk space — the app itself is light; every engine you enable (voice, image memory, local models, OCR) downloads its models locally. With all engines active, plan for more than 30 GB.
  • Windows — Windows 10 or 11, 64-bit (x64, Intel/AMD).
  • macOS — Apple Silicon only, M1 minimum. Intel Macs are not compatible.
  • Linux — x86-64 (AppImage or .deb). ARM is not supported.
Intel Macs

The macOS build requires Apple Silicon (M1 or newer). Mnemosyne OS does not run on Intel Macs.

Download​

Get the installer from mnemosyne-os.io/download — one card per platform, and the button downloads directly (files are hosted on the public releases; no account, nothing server-side):

The download page at mnemosyne-os.io/download — Windows, macOS and Linux cards

The Windows installer is digitally signed (Certum certificate, verified publisher) — no "unknown publisher" warning. A portable build is also available on the same page.

In progress

Install steps with screenshots are being written.

  • Windows — signed installer (Certum): what SmartScreen may show and why, install steps, where the app lives.
  • macOS — install steps and the first-open dialog.
  • First launch: what the app creates on disk, and where (nothing leaves your machine).
  • Updating: how in-app updates work.
