+## Limitations
+
+### Cursor not-allowed
+
+The ButtonBase component sets `pointer-events: none;` on disabled buttons.
+which prevents the appearance of a disabled cursor.
+
+If you wish to use `not-allowed`, you have two options:
+
+1. **CSS only**. You can remove the pointer events style on the disabled state of the `<button>` element:
+
+```css
+.MuiButtonBase-root:disabled {
+  cursor: not-allowed;
+  pointer-events: auto;
+}
+```
+
+However:
+
+- You should add `pointer-events: none;` back when you need to display [tooltips on disabled elements](/components/tooltips/#disabled-elements)
+- The cursor won't change if you render something other than a button element, for instance, a link `<a>` element.
+
+2. **DOM change**. You can wrap the button:
+
+```jsx
+<span style={{ cursor: "not-allowed" }}>
+  <Button component={Link} disabled>disabled</Button>
+</span>
+```
+
+This has the advantage of supporting any element, for instance, a link `<a>` element.
