macOS
The desktop operating system developed by Apple for Mac computers, based on a Unix kernel and supporting both Apple Silicon and Intel dual architectures.
Core Facts
A sandbox is a technical mechanism that restricts program execution to an isolated environment, with the core idea that even if the isolated program exhibits malicious behavior, it cannot affect the host system or external environment.
Apple advances Apple Intelligence by leveraging its on-device privacy advantages and the iOS/macOS ecosystem.
macOS menu bar apps reside permanently in the system status bar at the top of the screen as small icons, expanding into a function panel or dropdown menu when clicked.
Timeline (last 90 days)
When a screen-sharing session is active, macOS suppresses incoming calls before they ring, with the log recording outcome: suppressed; reason: display shared; after enabling notifications when mirroring or sharing the display, all 48 incoming calls within five minutes were allowed.
On a Mac without a camera, the UI accessibility tree node count during a FaceTime call is zero, causing the accessibility probe to keep returning idle throughout a 448-second call, so the watchdog erroneously shut down the active session at about 14 seconds.
Claude Code requires macOS 13 or later or Windows 10 or later and 4 GB of RAM; the ChatGPT Mac app requires macOS 14 or later; the browser version of Gemini has no special requirements.
On Linux and macOS, LU can only rely on screenshots and cannot determine what a click will press, so every click is asked about as a sensitive action; on Mac it also requires the two system permissions of Accessibility and Screen Recording, and the model must have image input capability.
LU's computer control has only been verified point by point on Windows (a Windows 10 machine); Linux has not actually been run in the app and requires an X11 session; macOS is integrated but not sufficiently tested; the control list and autonomous mode exist only on Windows.
OpenGL support on macOS has remained stuck at version 4.1 and has not been updated for years.
MeetPaw is a lightweight macOS menu bar app that generates an instant Google Meet, Zoom or Microsoft Teams meeting link with a click of the icon and automatically copies the link to the clipboard once created.
MeetPaw's target users are macOS users who rely on video conferencing daily and frequently need to create meeting links on the fly; for users whose meetings are scheduled via calendar with links generated automatically, or who use only a single platform and are accustomed to desktop clients, the marginal benefit is limited.
The ps command on macOS does not support the sid keyword; the closest option, sess, prints the hexadecimal kernel session pointer rather than the session ID.
On macOS since 10.15, the HUP option of the default login shell zsh is on by default, sending SIGHUP to running jobs when the shell exits.
