Here is the correct procedure to install the Sentinel drivers on macOS High Sierra
First of all, download the following drivers:
MacOS will tell you that this installer come from an unidentified developer and will not launch it. You have to open the System Preference and select "Security and Privacy". Click on the lock at the bottom left corner to do some modifications in this window. As you can see, there is white button "Open Anyway" which is displayed, click on it. The OS will display another window, click on "Open". The OS will launch the driver installation, follow what the installation program says until this window appears: MacOS blocks Sentinel Driver, you have to allow it, returns into the System Preference in "Security and Privacy", a white button "Allow" should have appeared (if not, leave System Preference and re-open them)
Click on "Allow", now Sentinel driver should be ready.
Launch TVPaint and enjoy !
Normally, we don't test MacOS beta, because things can change and problems mainly come from Safenet driver.
We can't do much things about Safenet drivers because we don't develop them, it's Safenet/Gemalto responsibility.
Exceptionally, I decided to test Mojave beta... and everything works fine with the dongle.
BUT, I do things in a certain order and I think this order should be respected because it seems to work on MacOS High Sierra too (I'm not sure about that).
First, before opening TVPaint or installing it, you must install Safenet driver version 7.4.2,
you can find them here: https://sentinelcustomer.gemalto.com/se ... =all&l=all
Unfortunately, this is NOT the version which come with TVPaint dmg, you have to download it.
New Safenet driver seems to be worst. They worked at the beginning on High Sierra (that's why we put them in the TVPaint dmg) but now, they seems completely useless.
Note that MacOS will tell you that drivers are not safe (!) and that you will have too allow them in System Preferences -> Security and Privacy and click on the "Allow" button.
Then only you can install and launch TVPaint.
If you launch TVPaint before installing drivers, you have to completely delete TVPaint. So remove it from the Application folder (or where you put it) and remove config directory too.
You can find them in your library: /Users/YOURNAME/Library, you will find some TVPaint folders.
Then, install Safenet drivers and re-install TVPaint.
Commercials ask to do this to some people who have the same problem and it seems to work (but it's still a hypothesis)
Hope it will work for you.
