Rosetta (M1+) Guide

When Apple Silicon users need Rosetta to run Intel-only After Effects plugins — and when they don't.

When You Need Rosetta

Apple Silicon Macs (M1/M2/M3/M4) run native ARM apps by default. Older After Effects plugins built exclusively for Intel processors won't load in a native ARM host — you'll see errors like "This effect is not compatible with this version of After Effects."

Rosetta 2 is Apple's translation layer that lets Intel apps run on Apple Silicon. Running After Effects through Rosetta allows Intel-only plugins to work, but at a performance cost — translation adds overhead. Only use Rosetta when you genuinely need a plugin that has no native Apple Silicon build.

AE 2024+ removed the Rosetta toggle. Intel-only plugins simply won't work on AE 2024+ on Apple Silicon. If you depend on these plugins, stay on AE 2023 or earlier — or find native plugin updates.

How to Enable Rosetta

  1. Find the app bundle. Open Finder → Applications → Adobe After Effects folder. Right-click the .app — not a desktop shortcut — and choose Get Info.
  2. Check "Open using Rosetta." Close Get Info and launch AE normally.
  3. If the option is missing: Rosetta may not be installed. Open Terminal and run: sudo softwareupdate --install-rosetta --agree-to-license

AE 2024+ and Intel Macs won't show this option — on those systems Rosetta is either unavailable or unnecessary.

Which AE Version to Use

After Effects 2021 and older will not launch on macOS 14 (Sonoma) or later. If you're on a recent macOS, you need AE 2022 or newer. The tradeoff: AE 2022–2023 still support Rosetta for Intel plugins. AE 2024+ does not. Pick the newest AE that runs both your macOS and your required plugins.

Plugin Compatibility

Apple Silicon Native — No Rosetta Needed

BCC, Crossphere Bokeh, Deep Glow, Dehancer, Element 3D, FilmConvert Nitrate, Glitchify, Magic Bullet Looks, Modulation, Omino, Optical Flares, Pixel Sorter, RSMB, Saber, Sapphire, Signal, Trapcode, Twixtor, Universe, and VFX Suite all have native Apple Silicon builds for current versions.

Intel-Only — Rosetta Required

Twitch and Shooter Suite are discontinued and remain Intel-only. If Rosetta isn't available on your AE version, these plugins won't work. Scripts and CEP extensions are unaffected by architecture.

Troubleshooting

Plugin still says incompatible

Confirm you toggled Rosetta on the actual .app bundle (not a shortcut). Fully quit AE and reopen. On AE 2024+, Rosetta won't help — you need a native plugin build or an older AE version.

Performance is slow with Rosetta

Expected — translation adds overhead. Upgrade to Apple Silicon-native plugin builds and run AE natively for best performance.
