Logitech: The Tale of Two Apps

Logitech gives you a choice: the "Heavy" way (G Hub) or the "Pro" way (OMM).

Option A: G Hub (The Bloat)

**The "Agent" Leak:** A background process called lghub_agent.exe has a known memory leak. If you leave it running for days, especially while streaming on Discord, it can eat up gigabytes of RAM.

**The macOS Sequoia Disaster:** In late 2024/early 2025, G Hub completely broke on macOS Sequoia (15.x) due to a security certificate expiry. If you are on Mac, you *must* download the specific "Logi Certificate Patch" or G Hub will simply say your mouse is "Inactive."

Option B: Onboard Memory Manager (The Holy Grail)

**Recommendation: Use OMM. Period.**

✓
What it is: A single .exe file (approx. 12MB). No installation. No background services.
✓
What it does: Updates firmware, changes DPI, polling rate (including 8000Hz on Superlight 2), and rebinds buttons.
✓
The Limit: It cannot do complex macros (like "Ctrl+C" on a side button) or advanced lighting effects. It is purely for hardware performance settings.
