    Article: 7 min

    The article discusses an unconventional approach to making macOS 26 consistently bad by modifying the corner radius of UI elements in third-party GUI apps using custom code and a dylib file.

    This approach may lead to increased personalization and customization of macOS UI elements but could also introduce security risks if not used carefully.
    • Disadvantages of upgrading to macOS 26 due to inconsistency in window corners
    • Proposal for making everything more rounded instead of roundless
    • Code implementation and dylib usage for modifying corner radius
    Quality:
    The article provides a clear, step-by-step guide with code examples for customization.

    Discussion (239): 52 min

    The comment thread discusses various opinions and experiences related to macOS window management, rounded corners, and the overall user interface. Users express preferences for different window management styles, with some advocating for tiling managers or criticizing the default macOS approach. The discussion also touches on the impact of design choices like rounded corners on usability and aesthetics, as well as the evolution of macOS UI over time compared to other operating systems.

    • Maximizing windows is not a common practice among macOS users, especially on laptops with smaller screens.
    • Rounded window corners are disliked by some users due to their visual impact and lack of clarity.
    Counterarguments:
    • Maximizing windows can be useful in certain contexts, such as when working with large monitors or specific applications like IDEs.
    • Rounded corners are a design choice that some users appreciate for its aesthetic appeal, despite potential usability issues.

    Discussion (89): 23 min

    The comment thread discusses various aspects of display technology, including refresh rates and power consumption in relation to battery life improvements. It also delves into the comparison between OLED and LCD displays, with a focus on LG's new low-leakage TFT for reducing power usage without compromising image quality.

    • Phones and watches have been using low refresh rates to enable battery improvements
    • Apple Watch Series 5 (2019) has a refresh rate down to 1Hz
    • M4 iPad Pro lacks always-on display despite OLED panel with variable refresh rate
    Counterarguments:
    • What's the real-world battery life though? My mac gets 8 hours real world; 16 in benchmarks; 24 claimed by apple.
    • Last I checked: the XPS was one of the few laptop product lines offering native Linux (Ubuntu) as an alternative default configuration option to order
    • It's how I got mine about 6-7 years back anyways, still works great (except the battery)
