Does it cover my apps?
No. The weather sits on the desktop, behind every window.
Will it slow my Mac down?
It is a small native app and only draws on the desktop.
Can I still click my desktop?
Yes. Clicks pass through; only snowballs and the planets control panel can be grabbed.
What does it run on?
macOS 14 or later, on Apple silicon and Intel Macs.
How do I turn it off?
Choose Off in the menu bar menu, or quit it there.
How accurate are the planets?
Their positions around the Sun are computed from NASA JPL orbital elements for the date shown. Distances and sizes are compressed so everything fits on screen. Positions are most accurate between 1800 and 2050, and the moons orbit at a sped-up pace.
Is it on the Mac App Store?
No. Snowglobe is a direct download from this page. It is signed with an Apple Developer ID and notarised by Apple, so it opens without warnings.
