Is there a way to temporarily enlarge the mouse pointer like Apple's "Shake to find" does? I'm aware of Apple's "Shake to find" feature, which enlarges the pointer (too briefly for me), and I occasionally use it.

I'm also aware of (increasingly unstable and out-of-date) third-party programs like "Mouse Locator" and Mouseposé, both of which suffer from lack of upgrades to keep up with Mac OS versions.

I'm looking for a way to trigger the temporary big cursor effect of "Shake to find" without shaking the mouse - as I want to keep the cursor near the thing I want to highlight.
There is way to increase the size of your cursor, but it will stay that size until you change it again. Maybe making the cursor a little bigger will help?

Go to System Preferences and click Accessibility. Then on the left click on Display. Click on the subsection called "Cursor", then use the slider to set the cursor size. You can also turn off the feature where your cursor expands when you shake it by unchecking the box.
