"You do not have permission to open the application" error

If you are affected by this error, you may be unable to launch Sensei during the first attempt after a reboot.

Instead of Sensei launching, you may get the error:

You do not have permission to open the application "Sensei".

Followed by a crash log that contains the words:

Exception Type:        EXC_CRASH (Code Signature Invalid)
Exception Codes:       0x0000000000000000, 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY
Termination Reason:    Namespace CODESIGNING, Code 0x1

After thorough investigation, we've concluded that this is not an issue with Sensei.
This is an issue that originates from within macOS. It affects several apps from different vendors, and Apple has acknowledged to developers that this error is under active investigation by them. For now, we have to wait for an official solution to this problem.

Temporary workarounds to this issue:

• Launching the app a second time should proceed without issues.
• Some users have reported that booting their Mac in safe mode, launching Sensei there, then rebooting normally have resolved this issue.
• Try downloading and reinstalling the app from the website.
