Default Folder X 6.1b3 beta: Support for Warp, bug fixes and less frequent reminders from Sequoia

The third beta build of Default Folder X 6.1 is available, adding support for the Warp terminal app and fixing several bugs that occurred in the previous beta (and in Default Folder X 6.0.8).

The other notable change is that this build won’t trigger Sequoia’s screen recording reminders nearly as often. Sequoia puts these up several times a day if an app is capturing screen images, which Default Folder X does as part of its normal functioning. Contrary to what this alert implies, DFX isn’t doing anything nefarious, just making its manipulations of Open and Save dialogs less jarring. The details are here. I’ve reduced the frequency of the reminders by abandoning Default Folder X’s automatic detection of dark / light mode in individual Open and Save dialogs, which required capturing an image from the screen.

To explain a bit: Some apps (including QuickTime Player, Affinity Photo, Affinity Designer and Rogue Amoeba Fission) let you change their appearance separately from the system-wide light / dark mode setting. There’s no generic way for another app like Default Folder X to tell which appearance they’re using other than taking a visual snapshot of one of the app’s file dialogs and checking to see whether it’s dark or light. I know that may sound stupid, but that’s the way macOS works – and honestly, for most normal, stand-alone applications this capability isn’t necessary, so I can understand why Apple doesn’t provide any sort of API to query an app’s appearance mode.

Anyway, without that information, Default Folder X may end up with the wrong light / dark mode for its toolbar around a file dialog, as well as for some of the controls within it – like this:

It doesn’t change the functionality that you get from Default Folder X, but it’s a bit jarring – and ugly. So, that’s the tradeoff – to stop Sequoia from whining at you every day, Default Folder X has to be less capable (and yes, I’ve filed a bug with Apple, but unless they get a lot of complaints I don’t think they’ll change this “feature” in Sequoia).

Default Folder X attempts to detect these situations using a different, application-specific method, and will currently do the right thing with the above-mentioned apps (QuickTime, Affinity apps and Fission). If you encounter this mismatch in other apps, let me know at DefaultFolderX@stclairsoft.com and I’ll do my best to find a way to detect the appearance for that app.

Grumble.

At any rate, a full change history and download links for Default Folder X 6.1b3 are available on the Beta Testing page.

    The new behavior affects apps like DFX, but not only… It also makes all remote desktopping applications virtually useless (since you have to be in front of the Mac to allow access).
    I’m not sure whether they’ll provide an alternate API for these sorts of apps, but if not, they will end up with far more people complaining about the new “feature”.

      Oh wow – I hadn’t considered that – good point! Apple’s release notes imply that using newer screen recording API’s may eliminate the alerts:

      “Applications utilizing deprecated APIs for content capture such as CGDisplayStream & CGWindowListCreateImage can trigger system alerts indicating they might be able to collect detailed information about the user. Developers need to migrate to ScreenCaptureKit and SCContentSharingPicker. (120910350)”

      but I tried using the ScreenCaptureKit screenshot API and still got the warnings. Perhaps that’s an error – I filed a bug with Apple and am hoping they’ll at least reply to it.
