There’s a new public beta version of Default Folder X available – it’s Default Folder X 5.2.6b7.
You’ll want it if you’re running Mojave 18A384a or higher, as the new Mojave builds require “usage statements” built into applications as part of their privacy controls. Previous betas of Default Folder X didn’t have these, resulting in newer iterations of Mojave summarily killing it if it tries to access protected folders, like those containing your contacts or music.
This Default Folder X build also includes a bunch new dialogs to alert you when it hasn’t been given adequate access to things in System Preferences > Security & Privacy > Privacy. The biggest stumbling block is access to Automation — giving DFX permission to use AppleScript to talk to the Finder, Path Finder, ForkLift and System Preferences. DFX uses AppleScript to get lists of open windows and navigate to folders and files in Finder / Path Finder / ForkLift, as well as opening System Preferences to the right preference pane so you can update necessary settings.
While there’s definitely a need for Mojave’s increased security, it’s a bit piecemeal at present. I’d love it if Apple would provide developers with some sort of API to help inform users in one shot of everything that an application needs access to, and to help them configure that access conveniently. As it stands right now, you’ll encounter multiple alerts as you use Default Folder X — they pop up in the middle of whatever you’re doing when Default Folder X first tries to touch something that’s protected. They’re not terrible, but they interrupt what you’re doing and, as such, aren’t presented at a time when you’re likely to devote your full attention to the security choice you’re being asked to make. So be prepared for a few alerts when you first start using Default Folder X in Mojave — it’s now the price we pay for additional security.
Oh, and on top of all the security shenanigans, Default Folder X 5.2.6b7 also tracks your recently used files much more effectively, even if the Recent Items system in macOS misses them. Something I’m happy to have finally sorted out!
