Posterino 5.5 focuses on offering support for macOS 15 Sequoia, along with improvements to the online help and several user interface components.
The online help home screen has been redesigned to merge the HTML help’s table of contents with media items, featuring a new “Welcome” section that prominently displays onboarding topics. The online help now supports dark mode for better visual consistency across different system preferences. When importing images using File > “Import Images”, the default “Add” button now displays the selected folder name to enhance clarity during the import process.
Key fixes address compatibility with macOS 15 Sequoia, ensuring the image browser respects image bounds and rubber-band selections work as expected under the new operating system.
