Wallper 1.5.1: Launch at Login Fixes and a Clearer Lock Screen Setup
Fixes for Launch at Login failing to register with macOS, empty previews during fast scrolling, and a step-by-step lock screen installation flow.
Three fixes, all of them in places where the app was asking people to trust it and then not quite delivering.
Launch at Login
Launch at Login could occasionally fail to synchronise with system services, which produced the most confusing possible outcome: the toggle stayed on, and the app did not start.
macOS handles login items through SMAppService, and registration can fail for reasons entirely outside an app's control. The system may decline it, another process may hold a stale registration, or the request may not survive an update. Wallper was treating the request as though it had succeeded, so the interface reported a setting that was not actually in force.
The integration was refined so registration is confirmed rather than assumed, and errors from system-restricted states are surfaced clearly instead of silently swallowed. If macOS refuses, you now find out.
Enabling it in the first place is covered in 1.0.9.
Previews During Fast Scrolling
An edge case could leave preview cards empty when scrolling quickly or on an unreliable connection. The requests were being cancelled as cards left the viewport and not reliably restarted when they came back, so a fast scroll up and down left a trail of blank cards that never recovered without a reload.
Previews now load consistently through both, continuing the pipeline work from 1.3.2.
Lock Screen Setup
The lock screen installation flow was redesigned to guide you through it properly.
Setting a lock screen wallpaper touches system permissions and configuration that most people have no reason to have seen before, and the previous flow moved too fast through the parts where it mattered. Extra stages were added so each permission and configuration step is explained as it comes up.
Guiding someone through a permission prompt is worth doing carefully. A dialog that arrives without context gets denied, and a denied permission usually looks like a broken feature rather than a decision that was made.
The result is fewer failed first attempts. There is more in lock screen wallpapers, on the lock screen support page, and in the full guide to setting a live wallpaper on your Mac lock screen.
