Is it safe to keep a MacBook running with the lid closed?
Run a closed MacBook without worrying about heat or battery.

Yes, as long as it has airflow and enough power. Keep the Mac on a desk or another hard, open surface, never in a bag, and plug it in for long jobs. Pulsida also switches closed-lid mode off at 10% battery or if your Mac gets critically hot.
Step by step
- 1
Give it air
A desk or table, not a bag, a bed or a sofa.
- 2
Plug in for long jobs
On battery, Pulsida stops at 10% so your Mac can sleep.
- 3
Use a timer
Keep your Mac awake only as long as the job needs.
- Heat
- A closed laptop has less room to cool down. Heavy work is fine on an open surface. Pulsida turns closed-lid mode off if your Mac gets critically hot and sends a notification.
- Battery
- A Mac that's awake uses more power than one that's asleep. Pulsida turns closed-lid mode off at 10% so your Mac has enough charge to sleep and wake up again.
- Bags
- Never keep a Mac running with the lid closed in a bag or sleeve. Stop Pulsida before you pack your Mac away.
