Mac vs PC for Live Events: Which Laptop Should You Put on the Tech Desk?

TL;DR:

• Presentations: PCs edge it for PowerPoint and corporate compatibility.

• Playback & audio: Macs are rock-solid for QLab, Dante, and pro media workflows.

• Video switchers & capture: Both work—PC offers broader driver support (capture cards, vMix), Mac offers stability with fewer variables.

• HDCP & adapters: Macs can be fussier about HDCP handshakes and dongles; PCs offer more predictable HDMI behavior.

• Best practice: Choose per show: PC for slide-heavy, corporate decks; Mac for playout, show control, and audio-centric gigs. Many productions bring both.

Why this choice matters for live events

In live production, the laptop you pick affects signal reliability, latency, and how quickly you can recover when a presenter hands you a last-minute file. The goal isn’t brand loyalty—it’s risk management.

Presentation Work: PowerPoint, Fonts & File Panic

PC advantages

• Native PowerPoint parity: Features like embedded media, custom fonts, rare transitions, and Presenter View behave most predictably on Windows.

• Widespread corporate standard: Guests’ decks (and their macros) often assume Windows—reducing last-minute fixes.

• HDMI/EDID familiarity: Windows drivers and GPU control panels (NVIDIA/Intel/AMD) provide granular output control (resolution, refresh rate, color format).

Mac watch-outs

• PowerPoint for Mac differences: 99% is fine; that last 1% (legacy animations, ActiveX, embedded codecs) can break at showtime.

• Keynote ↔ PowerPoint conversion: Converting Keynote to PPT can shift layouts or fonts—test early.

Live-safe tip: If the keynote speaker demands a Mac for their deck, export a tested video fallback (ProRes/MP4 with baked audio) and keep a PC-native PPT ready.

Media Playback & Show Control

Mac strengths

• QLab / Playback tools: QLab (macOS) is a staple for cued audio/video, MIDI/OSC control, timecode, and failsafe show calling.

• Audio over IP: macOS plays nice with Dante Virtual Soundcard, aggregate audio devices, and low-latency monitoring.

• Stability: Fewer hardware permutations reduce driver drama during load-in.

PC strengths

• vMix / Resolume / wider I/O: PCs pair beautifully with vMix, Resolume, and a wider range of capture cards and NDI/SDI I/O at competitive price points.

• GPU horsepower per £: Windows laptops with RTX GPUs deliver strong H.264/H.265/AV1 hardware encoding and multiple outputs.

Bottom line: If your show is cue-driven media and audio, Macs (QLab) are brilliant. If it’s live switching, multiple capture inputs, and GPU-heavy tasks, a Windows laptop with RTX graphics often wins.

Video Outputs, Adapters & HDCP

The HDCP story (where Mac can be pickier)

• HDCP handshakes: macOS can assert HDCP more aggressively with certain apps/streams. On some projectors and older switchers, this triggers blank screens until you route through compliant gear or strip (legally: disable protected playback) by using approved sources.

• Adapter roulette: USB-C → HDMI/DP dongles vary wildly. Cheap adapters can misreport EDID, causing 48/50/60 Hz mismatches or odd color space.

• Mirroring vs extended: macOS display mirroring across mixed-rate chains can be quirky; set extended desktop, lock resolution/refresh, and test.

PC predictability

• Drivers & control panels: NVIDIA/Intel utilities give precise control over EDID, RGB/YCbCr, full/limited range, and scaling.

• Native HDMI ports: Business-class PCs often include full-size HDMI or miniDP, reducing dongle risk.

Live-safe tip: Carry known-good, active adapters (USB-C → HDMI 2.0, USB-C → DP 1.4), an EDID emulator, and set outputs to 1920×1080 @ 50/60 Hz as required by the venue switcher.

Conferencing & Hybrid Sessions (Zoom/Teams/Meet)

• Mac: Consistent AV device routing, tidy echo cancellation, and steady CPU/GPU utilisation with OBS + NDI for simple pipelines.

• PC: Broader virtual camera and driver support, easier integration with hardware capture (Magewell, Blackmagic, AJA), and vMix as an all-in-one switcher/streamer.

Rule of thumb: If you’re mixing multiple cameras and remote callers, PC with vMix is friction-free. For simpler webcam + slides + confidence monitor, Mac with OBS is serene.

Reliability & Recovery On Site

• Mac: Great under sustained load with fewer background updaters. Limited ports can be a single point of failure—protect that USB-C path.

• PC: More ports and configuration control; driver updates and OEM utilities can surprise you—freeze versions before show week.

Operational tip: Whatever you choose, disable auto-updates, pause antivirus scans, turn off sleep, and keep a cloned backup laptop beside the desk.

---

Cost, Availability & Accessories

• Mac: Higher upfront cost, excellent resale value. Budget for quality USB-C hubs, power-delivery, and audio interfaces.

• PC: More configurations at lower cost (especially GPUs). Budget time for driver validation and a consistent dongle kit.

Quick Decision Matrix

The Practical Kit List (Works for Either Platform)

• Adapters: 2× USB-C → HDMI (active), 1× USB-C → DP, 1× HDMI → SDI (backup), EDID emulator

• Audio: USB interface with line outs, 3.5mm → dual XLR, spare DI box

• Power: UPS on the show desk, spare chargers, ferrites

• Software: VLC, OBS, Dante VSC, test patterns, tone/noise files, font packs

• Policies: Local admin user, updates paused, known-good driver set, rollback plan

Our Recommendation

For most corporate presentation-heavy events: lead with a Windows PC for slide ingest and live switching, with a Mac standing by for media playback and audio control. For performance-style shows with timecode and complex cues, lead with Mac + QLab and keep a PC ready for capture/streaming. The best setups keep both on the desk and route via the switcher—so you’re never cornered by HDCP, codecs, or fonts.
