Acorn Installation Guide

Purchasing and Installing Acorn directly from Flying Meat

If you haven't already, take advantage of Acorn's 14-day trial period by downloading it from the Flying Meat website: https://flyingmeat.com/acorn/. Click on the button that says "Download and Try Acorn", and Acorn will be transferred over the Internet directly to your Downloads folder. Once that's done, navigate to your Downloads folder and find Acorn. If your browser didn't unzip the Acorn file for you, you might have a file named Acorn.zip - double-click on that and macOS will unzip the file, revealing the Acorn app. Double-click on Acorn to launch it, and you will be asked if you want to move Acorn to your Applications folder.

After using Acorn and deciding that it's right for you, you can purchase Acorn directly from the Flying Meat store: https://flyingmeat.com/store/. When the purchase is complete, you will receive a receipt with a link to auto-register Acorn. Click on the link that says "Click to register Acorn 8", and Acorn will open up and automatically enter your registration information.

In addition to this, an email with registration information is sent to you, which will unlock the trial period for Acorn. You should file this email away, and if you ever need to enter your registration information, launch Acorn and choose the Purchase ▸ Enter Registration Information… menu item. In the window that comes up, enter your registration information (copy and paste works best). If you ever misplace your registration, you can retrieve it from our website: http://www.flyingmeat.com/support/.


Purchasing Acorn from Apple via the Mac App Store

You may also purchase Acorn from Apple via the Mac App Store. To do so, open the App Store on your Mac and search for Acorn, or visit the following URL: https://flyingmeat.com/acorn/appstore/. To purchase, click the 'Buy App' button in the App Store. You will then be presented with a button to 'Install'. Click 'Install’, and Acorn will be placed in your Applications folder.

When Acorn is purchased from the Mac App Store, it does not require a registration number. If you previously were running the trial version of Acorn, it's best to remove it first. A search for "Acorn kind:app" (without the quotes, of course) will reveal them in the Finder. (Deleting them helps keep the App Store from being confused.)


Downloading Older Versions of Acorn From Our Website

Previous versions of Acorn are available via our legacy page: https://flyingmeat.com/legacy/


If you Previously Purchased Acorn on the Mac App Store and Need to Re-Install

Open the App Store application on your Mac. Log in to your App Store account if you aren't already logged in. Choose the Store ▸ Account (⌘0) menu item. The App Store will open a page where your previous purchases were made, and you can reinstall Acorn from there without being charged a second time.

If Acorn is not listed in your previous purchases, make sure you are logged into the account that purchased Acorn. You can change accounts using the Store menu item.
