Can not save still images on MacOSX

[jceaser]

Get the following when I try to capture a TIFF or PNG with an SVBONY SV105:

"Unable to create file for output"

Console.app dumps out: "modalSession has been exited prematurely - check for a reentrant call to endModalSession:"

I get the same using a SVBONY SV205 "Unable to create file for output" message in the application, also the modalSession in console, but also noticed a sandbox error.

Hope this helps.

I wonder if xattr -d com.apple.quarantine /path/to/file will fix the issue. The code will need to do something to trigger permissions I'm sure, but as a work around it may be helpful. I'll test and report back in a couple of days (got something else going on today).

[jceaser]

Okay so garçon is a drop box plugin which I think gets fired when you try to write an image file because they want to steal your images and back them up to dropbox (to cause you to fill up your quota faster and thus need to pay them). I have oaCapture saving to a folder in my home directory, not in Pictures or Documents where dropbox may be looking. I also gave oaCapture full disk access. I am not getting the garçon error any more but still not able to save png files. xattr did nothing for me.

[jceaser]

Console gives this error when I try to capture a png:

default 08:27:20.203340-0400 oaCapture modalSession has been exited prematurely - check for a reentrant call to endModalSession:

I think this is a code error and not a sandbox error.

[openastroproject]

I can't reproduce this at the moment.

I've set the save directory to my home directory and can save both TIFF and PNG format files. If I set the save directory to Pictures I get a pop-up asking if I want to allow oaCapture to have access to my photos. I answered yes to that and I can then save in a subdirectory of that.

I think the modalSession issue is a red herring here. I think there must be something else happening, but right now I can't see what that might be.

[jceaser]

I'm not having this problem now, after many system updates, closing the ticket.
