Please include your macOS version and, for license questions, your order number.
Installing
Open the downloaded Mac-Ninja.dmg and drag Mac Ninja into your Applications folder. Open it once — a little ninja appears in your menu bar. Click it to switch Ninja Mode on or off; right-click it for stats and settings.
Allowing Chrome access
The first time Mac Ninja checks your tabs, macOS asks whether it may control Google Chrome. Click OK. If you clicked “Don't Allow” by mistake, turn it back on in System Settings › Privacy & Security › Automation.
The Chrome helper
For full tab sleeping (tabs keep their icon and history), install the free Mac Ninja Helper extension: right-click the ninja › Install Chrome Helper.
Entering your license
Right-click the ninja › Enter License Key… and paste the key from your purchase email.
Moving to a new Mac
On the old Mac, right-click the ninja › Settings › Deactivate License on This Mac. Then enter the same key on your new Mac. Each license covers up to 3 Macs.
Uninstalling
Quit Mac Ninja from its menu, then drag it from Applications to the Trash. Every app is restored to normal speed when Mac Ninja quits. Optionally remove the folder ~/Library/Application Support/Mac Ninja.
