Ferrum 0.1.6
The macOS build catches up to 0.1.6, from the same source as the Windows build of this version.
The update notice does not apply here. The headline of this release on Windows is an update that announces itself on a card and installs itself when you press the button. On macOS the card can appear, but pressing Install cannot finish: the editor hands the payload to an installer that sits beside it, and no such program is built for macOS yet. Updating is still dragging a new Ferrum to Applications, and will be until that exists.
The terminal panel spans the window again. Splitting the editor cut the panel down to whichever half had the keyboard, so a shell reflowed and a running build's output rewrapped because you opened a file beside it. The panel is one band across the bottom; splitting it is Cmd+Shift+5.
A terminal named with an accent draws straight. The tab strip was placing glyphs by byte rather than by cell, so a shell titled café/bin drew everything after the accent a cell too far right, and an emoji in a title pushed the rest three cells over.
Three things sat a couple of pixels out of place and no longer do: the remote indicator in the corner of the status bar, the cross that closes a dialog, and a plugin's initials in the rail.
The application is signed ad-hoc rather than by Apple, so macOS quarantines it after a download and refuses the first launch. Clear the flag once, and it opens normally from then on:
xattr -dr com.apple.quarantine /Applications/Ferrum.app
Or open it, let it be refused, and allow it in System Settings > Privacy & Security. Do not right-click and choose Open: macOS 15 removed that bypass for applications with no Developer ID.
