The Application "Finder" does not have permission to open "(null)." Error

After updating to Sequoia 15.1 on my MacBook Pro with M1 chip, I tried running a midi app and received the following error message:   The Application "Finder" does not have permission to open "(null)."

After considerable time and efforts to run my favorite Mac Midi editing software MidiYodi 21.1 unsuccessfully, I came up with this solution:



How to Run MidiYodi under Sequoia macOS 15.1 error


Describe the bug
Trying to launch MidiYodi 21.1  Mac version 21.01 on Mac running Sequoia 15.1 give an error
The Application "Finder" does not have permission to open "(null)."




Environment and Version info (please complete the following information):

  • OS: macOS 15.1 Sequoia
  • System: Apple M1
  • Open MidiYodi Version 2021.1 

Additional context
Workaround is to select MidiYodi version 2021.1 and show the package contents of MidiYodi by holding down control key while clicking on the app  and then run JavaAppLauncher. 








Java launcher app appears in dock and the program MidiYodi runs just fine.  When I quit MidiYodi, then the javalauncher app quits too.



Replace "MidiYodi 2021.1.app" with your problem app name. 


Hope this helps!  


Of course, this will have to be the method of launching that app.  It does not work from the dock.  Hopefully, there will be an update that handles the signature problem in my midi app ... I have contacted their support to see if there will be a more permanent solution.

Hallelujah - Disklavier app for my Mark IV working again!

I noticed an update to the Disklavier controller app for iPhone and Mark IV today.  This update notification came on a version  I had loaded on my MacBook Pro with M1 chip.  When I checked on my iPhone the app wasn't listed as an update. So, I deleted the app from my iPhone and then searched for it on the application app for iPhone and reloaded it. 

I was excited that the app loaded with the screen to allow for searching for my piano.  Unfortunately, the search didn't work after a minute or so.  

I then re-booted my piano and that didn't work either. 

Then I noticed that the AirPort Express connecting my piano to my router was blinking yellow. So I unplugged the AirPort Express and waited a few minutes. and replugged it in.  It turned green.

I then shut down my Mark IV and restarted it so it could connect.

That worked!  I now can control my piano again from my iPhone.
