STEP 1.
Unzip STEAM parts 1-15 using Keka and extract the ISO wherever you like.

STEP 2(a)
Mount (open) the ISO image and drag the Spectrasonics folder from inside the ISO to wherever you want it to live. This can be an external drive, but for convenience use the default location "~/Library/Application Support/Spectrasonics/STEAM"

STEP 2(b)
Use the application "BatChmod" to give write permission to your newly created Spectrasonics folder and all subfolders/files.

STEP 3 (optional)
Create an alias to the Spectrasonics Folder which should be placed at the location in STEP 2. if you have not placed the actual Spectrasonics folder there.

STEP 4
No step 4 on MacOS.

STEP 5
Unzip Step 5 archive (do not change the folder hierarchy!) and double-click the .pkg installer file. You will need an admin password to install, as usual. DO NOT start Omnisphere yet.

STEP 6(a)
1. Unzip Step 6 archive and run Keygen App.
2. Move the VST and AU plugins from "Macintosh HD/Library/Audio/Plug-ins/(Components/VST)" to a new folder with write access.
3. PATCH the all the Omnisphere VST and AU plugins. Patch means click the "Patch" button in the keygen and direct it to the plugins; a dialog will open requiring you to point to the plugin you want to patch. The Keygen App will see the Mac plugin as just another folder. What you need to patch is inside the plugin; "plugin(seen as a folder)/Contents/MacOS/Omnisphere".
4. Move the plugins back into their respective folders; "Macintosh HD/Library/Audio/Plug-ins/(Components/VST)".

STEP 6(b)
Run Omnisphere in the Applications folder. It may take a while to load the first time. Do not panic. Be patient, after a while the Omnisphere registration window will open and provide you with a Challenge Code.

STEP 6(c)
Copy and paste (using right-click!) the Challenge Code into the Keygen's Challenge Code window.

STEP 6(d)
Press the GENERATE button and copy the generated Response Code. You can right-click and choose "Copy" if you're doing this in the keygen on the Mac. It will copy to the Mac clipboard.


STEP 6(e)
Paste the copied Response Code into the Omnisphere's Response Code Line by pressing the Paste tab. After this operation the key generator is no longer is needed.

STEP 6(f)
Press the Continue tab and when the next window appears, quit the Omnisphere application.

STEP 7
Unzip Step 7 archive (do not change the folder hierarchy!) and run the Omnisphere 2 Data Updater.pkg (Soundsource update) in the Mac folder. Your admin password will be required.

STEP 8
Unzip Step 8 archive (do not change the folder hierarchy!) and run the Omnisphere Data Updater.pkg (Patch library update) in the Mac folder. Your admin password will be required.

STEP 9
Unzip Step 9 archive (do not change the folder hierarchy!) and run Bob Moog Tribute Patch Library.pkg (Bob.Moog.Tribute.Patch.Library.Update) in the Mac folder. Your admin password will be required.

STEP 10
Run Omnisphere. You should be good to go...

N.B. Software updates kill the crack, so yo have to go through step 6 again after an update.
