Amphetamine can keep your Mac, and optionally its display, awake through a super simple on/off switch, or automatically through easy-to-configure Triggers.

Excelente e completamente gratuito

Poucos dos bons aplicativos para Mac são gratuitos. Este é um deles. Cheio de recursos, altamente customizável e com bom design que faz jus ao ecossistema macOS.

Indispensável para garantir a produtividade

O Amphetamine é um app essencial para qualquer usuário de Mac, principalmente MacBooks. Utilizo ele principalmente para reuniões e apresentações. O novo recurso de ficar ativo enquanto um arquivo está sendo baixado é impressionante, mas, e se este recurso fosse automático? Seria ainda mais incrível, não é mesmo?
Parabéns ao desenvolvedor! ❤️
