UI Browser 3 is a Universal app. It runs on an Intel-based Mac, and it runs as a native process on an Apple silicon Mac during the trial period and with a Paddle registration key. It requires Rosetta translation to run on an Apple silicon Mac with an eSellerate registration key.

UI Browser 3 is a free upgrade from UI Browser 2 with this qualification: On an Apple silicon Mac, you must run UI Browser 3 under Rosetta translation in order to continue using a UI Browser 2 eSellerate key issued on or before June 30, 2019. To run UI Browser 3 natively on an Apple silicon Mac, you must use a UI Browser 2 Paddle key issued after June 30, 2019, or purchase a new Paddle key.

Download UI Browser 3.0.2. It runs as a fully functional free trial, expiring 30 days after you first use it unless you enter a valid registration key. It requires macOS Sierra 10.12 or later, and it supports new Accessibility features introduced through macOS Big Sur 11. Go to Requirements for details.

If you already own a registration key purchased from eSellerate or Paddle for UI Browser 2, you can continue to use it to run UI Browser 3. If you do not own an existing key, you must purchase a key from Paddle, our current eCommerce provider. A Paddle key can only be used to run UI Browser 2.8.2 or later and UI Browser 3.

To purchase a Paddle key here on our website, go to the Online Store using any commonly available Mac web browser. If you have a discount coupon, you can enter the coupon number in the order form. Volume discounts are no longer available. When you receive your key from Paddle, launch UI Browser and choose UI Browser > Registration > Enter Key. Enter your email address and the key exactly as they were provided, and activate UI Browser when asked.

If you prefer to purchase a Paddle key within UI Browser, choose UI Browser > Registration > Purchase Key while you are connected to the Internet. Follow the instructions in the Paddle UI Browser purchase dialog, and activate UI Browser when asked.

Be sure to save your registration information in case you ever need to reinstall UI Browser. Individuals who have purchased this version of UI Browser are licensed to use it on their home computer, their office computer, and their laptop. If you need to deactivate UI Browser on one of them to install it on another computer, choose UI Browser > Registration > Deactivate. Before entering a Paddle key on a computer that is already registered with an eSellerate key, choose UI Browser > Registration > Unregister to remove the eSellerate registration.

Before running UI Browser 3 on an Apple silicon Mac using an eSellerate key, you must set up Rosetta translation by selecting the "Open using Rosetta" checkbox in UI Browser's Get Info window in the Finder. Digital River stopped selling eSellerate keys as of June 30, 2019, and it has not provided registration software that runs on Apple silicon. Then launch UI Browser and choose UI Browser > Registration > Enter Key, and enter your user name and the key exactly as they were provided.

When using UI Browser's Enter Key window to register a key, identify the User of a Paddle key by entering the email address to which Paddle emailed the key. Identify the User of an eSellerate key by entering the user's name as provided in the eSellerate email message.

Follow these steps to delete UI Browser and its supporting files from a standard installation on your computer: (1) Delete the "UI Browser" application file from the Applications folder. (2) Delete the "com.pfiddlesoft.uibrowser.plist" file from the user Library's Preferences folder at ~/Library/Preferences/. (3) Delete the "PFiddlesoft GUI Scripting Library" file from the user Library's Script Libraries folder at ~/Library/Script Libraries/. (4) Delete the "UI Element Scripts (PFiddlesoft)" folder and its contents from the local Library's Scripts folder at /Library/Scripts/.

You can still download an earlier release of UI Browser 2 and use an existing eSellerate key to run it. If you are using macOS Big Sur 11 or earlier, download one of these earlier releases of UI Browser 2: in OS X Yosemite 10.10 or later, UI Browser 2.9.2; in Mac OS X 10.7 (Lion) or later, UI Browser 2.7.0; in Mac OS X 10.6 (Snow Leopard), UI Browser 2.3.0; in Mac OS X 10.5 (Leopard), UI Browser 2.1.1; or in Mac OS X 10.4 (Tiger), UI Browser 2.0.5.

Releases of UI Browser 2 earlier than 2.8.2 have not been notarized, and they will no longer run on macOS Catalina 10.15 or Big Sur 11. In addition, they cannot be run with a new key from Paddle, and keys are no longer available for purchase from eSellerate. UI Browser 1.4.1 for Mac OS X 10.2 (Jaguar) and Mac OS X 10.3 (Panther) is no longer available, and registration keys purchased for UI Browser 1.4.1 or earlier are not valid for UI Browser 2.2.0 or later.
