We've recently had some users reporting problems when starting up Isadora, either as a crash or a freeze. It turns out that many of these issues were because they had upgraded their version of macOS, causing some drivers that are no longer compatible to crash or freeze. (This can also happen when using Apple's Migration Assistant to move to a new computer which has a later version of macOS.)

If Isadora is freezing during startup, you may be able to get a clue where the problem is by looking at the "splash screen."

  • If you see "Video Input: Initializing" in the splash screen, then the problem is likely a video driver or an audio driver.
  • If you see "MIDI: Initializing" in the splash screen, then the problem is likely a MIDI driver.

If it's crashing, you might want to make a screen recording so that you can perhaps see what's in the splash screen at the moment of the crash. (Also, in these cases, find the crash report, open a support ticket and send us the compressed [.zip] crash report.)

Now, the best solution for all of these problems is to use an uninstaller program or to follow the specific instructions provided by the software company that created the driver.

If you are 100% sure that the driver or component was installed by a third party software, you can also delete it manually. But never do this unless you are complelely sure, as you can damage your system to the point where the computer will not boot up!

  • Kinoni SoftVDIGX: The most common issue is a video digitizer component from Kinoni called SoftVDIGX. This component is not compatible with current versions of macOS. To solve the problem, you can just move the file at /Library/QuickTime/SoftVDigX.component to the trash.
  • Other VDIG Components: All video digitizer components are located in in the folder at /Library/QuickTime/. If you're sure that a component was installed by a third party, try moving it to the desktop and restarting Isadora.
  • MIDI Drivers: These drivers usually found at /Library/Extensions. To remove a MIDI driver, use an uninstaller program if possible, or follow the manufacturer's instructions for uninstalling. Only delete these items manually if you are completely sure it was added by a third party software. You should restart the computer after removing a MIDI driver.
  • Audio Drivers: These drivers are usually found at /Library/Extensions. To remove an audio driver, use an uninstaller program if possible, or follow the manufacturer's instructions for uninstalling. Only delete these items manually if you are completely sure it was added by a third party software. You should restart the computer after removing a MIDI driver.

If you're feeling at all unsure, open a support ticket. We'll help you resolve the situation as quickly as possible.
