Installing Oberon Workstation

The product is packaged as a single downloadable ".dmg" disk image named as "Oberon Workstation.dmg". Installation amounts to just copying the program to your "Applications" folder, or - if you prefer - to another folder, e.g. your ~/Applications/ folder in the home directory.

Open the .dmg file by double-clik. macOS will ask you confirmation for opening a downloaded item. Click "OK".
The disk image will display a covenient graphic folder panel, like:

Exampledmg

Follow the instruction to drag Oberon.app to your Applications folder. If there is already an old version of Oberon in your Applications you can overwrite it (but see below: "Removing the free App-Store Oberon application").
You may have to type your Administrator password to allow the copy. After installing in the Application folder the disk image can be unmounted/ejected. You can keep the .dmg file to install on your second computer or as a backup.

Removing the free App Store Oberon program

Before installing Oberon Workstation, it is recommended to remove the pre-existing free Oberon Application downloaded from the Mac App Store, if present.
This is accomplished easily by using Apple's "Launchpad" application: locate Oberon, press and hold untill the icons start "jiggling" a-la iPhone, and click the little cross on the old Oberon icon.

Your present Oberon folder(s) are not affected and will keep working, but your settings from the free Oberon application have disappeared. It is a good idea to refresh the Oberon system files in your folder(s) by using "Files > Restore System" when you start working with the new Oberon program (unless you have purposely changed your Oberon system).

First use of Oberon Workstation

Open Oberon Workstation by a double-click on its icon. Upon first use, you may see a warning, depending on your security setting in macOS. We recommend to use "Allow apps downloaded from App Store and identified developers" in the "Security & Privacy" settings panel of your Mac's system prefs. Confirm that you want to open the App.

The Oberon Workstation app requires the License Key that you have obtained from Paddle.com by email. Enter the License Key (conveniently copy/paste it from your email) and click "Done".

To start the Workstation, you need at least one directory that is dedicated to your Oberon work, and that will receive the Oberon System files. If you have no existing Oberon folders, or want to create a fresh new one, use the file/folder dialogue that is automatically displayed. This panel creates a new folder: you should type a new name or accept the default "Oberon" after navigating to the parent folder in which you want to create the new Oberon folder.
If you have an existing Oberon folder, cancel the new-folder dialogue, and use "File > Set Oberon Folder..." to select any existing Oberon folder.

Download and updates

To check your current version, and whether there is a new version, you can use Oberon > Check for Updates...
If there is a new version available, you can download it from "https://Paddle.com/..." by using the "Download" button. This will activate your default browser to actually perform the download. The result is a .dmg file containing the new Oberon Workstation.

When downloading or updating Oberon Workstation from our vendor Paddle.com, it turns out that some browsers (Chrome family) will flag the .dmg file as "dangerous" because it is not a "common download". This seems to be part of a non-Apple security provision to protect a PC computer.

With Safari, being adjusted to the Macintosh world, there is no download warning: Apple's macOS "Gatekeeper" will recognize Oberon Workstation as a trusted Apple Developer ID certificate-signed application and treat it accordingly.

While it is OK to download with other browsers (as long as it is from https://Paddle.com/..) and ignore the warning, to avoid the annoyance we recommend downloading/updating Oberon Workstation with Safari as your default browser, and notice the Developer ID class when first running the (updated) program.
