Can the Mac 16 GB run Wan Animate 2 (14B)?
Not at full quality. The 16-bit and 8-bit files are too big for the Mac 16 GB; the largest that fits is Q2_K (6.5 GB).
Q2_K (6.5 GB) fits with only 0.9 GB to spare (about 11.8 GB of 12.7 GB). Quality: heavy loss; a last resort. For better quality, Q3_K_M (8.6 GB) also runs, with about 1.2 GB spilling into system RAM - a little slower, still practical.

Alternatives: UMT5-XXL FP16 (11.4 GB). On a Mac, FP8 text encoders do not load, so a 16-bit one is listed - or a GGUF one, loaded with “CLIPLoader (GGUF)” from the ComfyUI-GGUF nodes. Sizes from Hugging Face, 2026-10-01.
Shared memory: about 20.1 GB of your 16 GB. On this machine the model, the text encoder, the VAE and the operating system all use the same memory. That is about 4.1 GB more than there is. It still runs: while the model works, the system compresses or swaps the idle text encoder, so loading and changing the prompt get slower. A smaller file or text encoder avoids that. calculated

“Needed” adds 4.5 GB of working memory for Wan Animate 2 and a 0.8 GB reserve. Sizes 2026-10-01. FP8 and INT8 files are left out on a Mac: Apple GPUs cannot compute FP8, so ComfyUI either fails to load them or converts them back to 16-bit, which saves no memory. Use a 16-bit or GGUF file.
03Measured and reported results
Nobody has sent measured numbers for this pair yet. If you run Wan Animate 2 on a Mac 16 GB, send your time per image and peak VRAM and it will appear here, credited.
04With more VRAM
With 24 GB you could run Wan Animate 2 at 8-bit or better (Q8_0, 18.1 GB) with no offloading: for example on the RTX 4090 24 GB, RTX 3090 24 GB, RX 7900 XTX 24 GB.
05About the Mac 16 GB
A Mac with 16 GB shares that memory between the CPU and the GPU. On current macOS the GPU may use about 12.7 GB of it by default (older macOS versions: about 11.5 GB); that is the figure used here. ComfyUI can go past it, but macOS then starts compressing and swapping memory and everything slows down. ComfyUI runs on Apple GPUs through PyTorch's MPS backend. 16-bit and GGUF files work; FP8 and INT8 files do not save memory on a Mac, so they are skipped. Speed is the catch: even the fastest Macs are several times slower per image than a desktop RTX card. Chips sold with 16 GB: M1, M1 Pro, M2, M2 Pro, M3, M4, M5, M6 (memory bandwidth 68.25–200 GB/s - the higher, the faster). Everything about Macs and local AI →

06Questions
How much VRAM does Wan Animate 2 need?
Around 11.8 GB with the smallest file (Q2_K) and 22.0 GB with an 8-bit file (INT8). The full 16-bit file needs about 38.1 GB.
Which Wan Animate 2 file should I download for the Mac 16 GB?
Q2_K (6.5 GB) from realrebelai/Wan-Animate-2_GGUFs. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
How much do I need to download for Wan Animate 2 on the Mac 16 GB?
14.1 GB: Wan-Animate-2-14B-TURBO-Q2_K.gguf, umt5-xxl-encoder-Q8_0.gguf, Wan2_1_VAE_bf16.safetensors, clip_vision_h.safetensors.
