Can the Mac 128 GB run Wan 2.2 Animate 14B?
Yes. 16-bit fits on the Mac 128 GB with 75.6 GB to spare.
16-bit (34.5 GB) needs about 39.8 GB in use, so 75.6 GB of the 115.4 GB stays free: room for a larger image, a LoRA or a ControlNet.

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 48.1 GB of your 128 GB. On this machine the model, the text encoder, the VAE and the operating system all use the same memory. That leaves room, so nothing has to be swapped to disk. calculated

“Needed” adds 4.5 GB of working memory for Wan 2.2 Animate 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.

04About the Mac 128 GB
A Mac with 128 GB shares that memory between the CPU and the GPU. On current macOS the GPU may use about 115.4 GB of it by default (older macOS versions: about 103.1 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 128 GB: M1 Ultra, M2 Ultra, M3 Max, M4 Max, M5 Max (memory bandwidth 300–800 GB/s - the higher, the faster). Everything about Macs and local AI →

05Questions
How much VRAM does Wan 2.2 Animate need?
Around 11.8 GB with the smallest file (Q2_K) and 22.6 GB with an 8-bit file (FP8). The full 16-bit file needs about 39.8 GB.
Which Wan 2.2 Animate file should I download for the Mac 128 GB?
16-bit (34.5 GB) from Comfy-Org/Wan_2.2_ComfyUI_Repackaged.
FP8 or Q8_0 for Wan 2.2 Animate on the Mac 128 GB?
Q8_0 (18.7 GB). The Mac 128 GB has no FP8 maths, so FP8 (17.3 GB) only saves memory and is a step further from the original.
How much do I need to download for Wan 2.2 Animate on the Mac 128 GB?
42.1 GB: wan2.2_animate_14B_bf16.safetensors, umt5-xxl-encoder-Q8_0.gguf, wan_2.1_vae.safetensors, clip_vision_h.safetensors.
