Clear Rhino 3D Cache on Mac

To free space, quit Rhino 3D first, then review the data it keeps for older versions in the McNeel folder. Your models are separate .3dm files and are not stored in that folder, so they are not touched.

Rhino 3D cache folders you can clear

Rhino 3D has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.

What Rhino 3D keeps in its data folder

Specific to Rhino 3D

Rhino 3D stores settings, plug-ins and templates for each version in one versioned folder under McNeel, which is the only app data location listed for it. The typical size of this data is 500 MB – 10 GB. Each version keeps its own data, so old versions leave their folders behind after you stop using them. Clearing helps when you see large folders for versions you no longer open. Your models are .3dm files saved wherever you chose, so they are not in this folder.

What changes after you clear Rhino 3D data

Your models stay where you saved them, and the version you still use keeps its own settings and plug-ins. Removing an old version's folder only affects that version, so confirm you no longer need it first. Move the folder to the Trash rather than deleting it, because items in the Trash can be restored until it is emptied. Whether you need to sign in again depends on your licence: a Rhino account may ask you to sign in, while a licence key is what to keep ready.

Open the app and check whether its settings offer a cache-clearing option.Save any open models, then quit the app completely.In Finder, open Library, then Application Support, then the McNeel folder.Move folders for old versions to the Trash, then open a model to confirm it works.

Frequently asked questions

Yes.

Will I have to sign in again after clearing?

It depends on how you licence the app. A Rhino account may ask for sign-in again, so keep your account details ready.

Why does the folder keep growing?

Each version you have used keeps its own settings and plug-ins, so older versions leave data behind.
