# What to do if AutoCut runs slowly on your Mac ?

👉 If you're on **Windows**, follow [this article](https://knowledge.autocut.com/en/article/what-to-do-if-autocut-runs-slowly-on-your-windows-1e0zgmu/) instead.

If AutoCut feels slow or laggy on your Mac, there are two possible optimizations you can try.

# 1. How to disable UI animations

Just like on Windows, some Macs—especially older or less powerful ones—may run smoother without interface animations.

Here’s how to disable them in AutoCut :
1. Open **AutoCut** in your editor (Premiere Pro or DaVinci Resolve).
2. Go to **Settings** (⚙️ icon in the AutoCut panel).
3. Find the option **Disable UI animations**.
4. Toggle it **on**.

AutoCut will immediately run with fewer visual effects, reducing the load on your computer and speeding up the interface.

Watch this quick video guide to see exactly how to turn off UI animations in AutoCut :

# 2. Check Rosetta settings on ARM-based Macs (M1, M2, etc.)

If you’re using a Mac with an ARM processor (such as M1, M1 Pro, M2, or newer), performance issues can also happen if AutoCut is opened using **Rosetta**. This isn’t necessary, since AutoCut is optimized for ARM, and can actually slow the app down.

### How to check and fix it :

**1. Open the Finder App**
On your Mac, click on the **Finder** app (usually available in your Dock).

**2. Go to the Applications Folder**
In the left sidebar, select **Applications** and scroll to find the **AutoCut** app.

**3. Access App Information**
Right-click on the AutoCut app and select **Get Info** (or "Read Information" depending on your macOS language settings).

**4. Check Rosetta Option**
In the information window, look for the checkbox **"*Open using Rosetta*"**.
* Make sure this box is **unchecked**.
* If it is checked, uncheck it to ensure AutoCut uses the full performance of your ARM processor.

|| 💡 Rosetta is a compatibility tool that helps apps designed for Intel processors run on ARM-based Macs. However, AutoCut is fully optimized for ARM processors, so using Rosetta is not necessary and can slow down performance. By disabling this option, you allow AutoCut to run natively on your Mac, which improves speed and responsiveness.


### 🔍 If the Rosetta option is missing

If you don’t see the **Rosetta option** in the information window, it means that the app is already running natively and this is not the cause of the slowdown.
In this case, please **contact our support team** so we can help you investigate further.
