Keep your Mac awake for Blender renders
An animation render is a marathon - hundreds of frames, hours of GPU and CPU time, and not a single keypress while it runs. macOS sees that idle input and sleeps the machine, stranding your render queue at frame 40 of 250. AwakeMate keeps the Mac awake the whole way through so the queue actually finishes.

When your Mac sleeps mid-Blender
Blender renders are exactly the workload macOS sleep was designed to interrupt: heavy, long and input-free. Kick off an overnight render queue and walk away, and the idle timer can put the Mac to sleep before the first sequence is done. You come back to a stalled job and a wasted night.
AwakeMate keeps it awake while Blender runs
AwakeMate recognises Blender by its process name, blender, scanning the running process list locally on-device. As soon as Blender starts crunching a render it is detected, and the Mac is kept awake without you flipping any switch.
Detected process: blender
Tip: turn on "Sleep when tools go idle"
Turn on "Sleep when tools go idle" for Blender. While blender is actively rendering it pins the CPU and GPU, so AwakeMate keeps the Mac awake; the moment the final frame of your overnight render queue is written and Blender goes quiet, the Mac sleeps on its own. You get the whole queue rendered and a machine that powers down the instant it is done - perfect for "keep mac awake blender render" jobs you start before bed.
Get the most out of it
- Set up your full render queue in one Blender session so AwakeMate holds the Mac awake across every frame, not just the first sequence.
- With idle-sleep on, an overnight queue powers the Mac down as soon as the last frame lands - no need to leave it running idle until morning.

Will AwakeMate keep my Mac awake for an entire overnight render queue?
Yes. As long as blender is actively rendering, AwakeMate holds the Mac awake. With "Sleep when tools go idle" on, it then sleeps the machine the instant the final frame is done.
Does it use the GPU or slow my render down?
No. AwakeMate only places a lightweight IOKit power assertion - the same mechanism as macOS's caffeinate. It adds no rendering load and never changes your energy settings.
Does AwakeMate see my .blend files or scene?
No. It reads only the short process name blender on-device, with zero telemetry. Your scenes, assets and output frames stay entirely private.
What's the best way to keep my Mac awake to finish a Blender render?
Add blender to your watched tools and AwakeMate holds the Mac awake automatically the moment a render starts crunching, with no switch to flip. Turn on "Sleep when tools go idle" and it powers through the whole frame queue while Blender is busy, then sleeps the machine the instant the last frame is written - so a render you start before bed finishes and the Mac still powers down on its own rather than sitting awake until morning.
Is there a way to keep my Mac awake for a render without caffeinate?
Yes - that's the whole point of AwakeMate. You can run caffeinate in a terminal, but you have to remember to start it, remember to stop it, and it holds the Mac awake for everything with no per-tool awareness and no status readout. AwakeMate watches for blender specifically, shows the kept-awake state in the notch, and with idle-sleep on releases the Mac the moment the render is done - none of the manual book-keeping caffeinate needs.
Can I leave a Blender render going overnight on battery?
You can let it run unattended, but a render pins the CPU and GPU and will flatten a battery well before a long queue is done, so for overnight jobs it's best to keep the Mac on power. AwakeMate also has a low-battery cutoff you can set, so if you do run off the charger it will stop holding the Mac awake once the battery drops below your threshold rather than draining it flat. Note this keeps the Mac awake with the lid open; closed-lid renders still sleep unless you're on power with an external display.
Will it keep my Mac awake for Blender with the lid closed, even on battery?
Yes. Turn on "Keep awake with the lid closed" in Settings - Options and approve the one-time helper; AwakeMate then keeps the Mac awake with the lid shut while Blender runs, and dims the built-in screen so it is not draining the battery under the lid. It works on most Apple Silicon Macs (Apple forces sleep on some, so close your lid once to confirm). It works on battery too, but real work drains it faster, so keep it on power for long runs.
