四、详细安装教程

安装 JustStream for Mac 的过程非常直接，但为了确保首次使用的用户能顺利完成，我们整理了以下步骤。

步骤1：下载并打开安装包

从本页面下载 JustStream v2.5 激活版后，双击 .dmg 文件。系统会弹出安装窗口，通常包含一个应用程序图标和一个“应用程序”文件夹快捷方式。

步骤2：拖拽安装

将 JustStream 图标直接拖拽到旁边的“应用程序”文件夹中。此操作会将软件复制到你的 Mac 硬盘，完成核心安装。拖拽完成后，等待几秒钟让系统完成文件索引。

步骤3：首次启动与授权

打开“启动台”或“应用程序”文件夹，找到并双击 JustStream 图标。首次运行时，macOS 可能会弹出安全提示，因为该应用来自未识别的开发者。此时，请前往“系统偏好设置” > “安全性与隐私” > “通用”，点击“仍要打开”按钮。根据提示，输入你的系统密码以确认授权。

步骤4：激活软件

启动后，程序会提示输入激活码。我们已经为你准备了激活版，通常软件会自动完成激活，或你可以在“帮助”或“设置”菜单中找到“输入激活码”选项。输入提供的序列号，点击“激活”即可解锁全部功能。

步骤5：配置麦克风与屏幕录制权限

JustStream 需要屏幕录制权限才能进行镜像操作。首次尝试镜像时，系统会弹出权限请求。请务必点击“允许”，或在“系统偏好设置” > “安全性与隐私” > “隐私” > “屏幕录制”中，手动勾选 JustStream。同理，若需要录制系统音频，也需在“麦克风”权限中开启。

五、常见问题 FAQ

我们整理了用户在使用 JustStream 时最常遇到的几个问题，希望能帮助你快速排障。

Q1: 为什么我的 Mac 找不到 Chromecast 设备？

请确保你的 Mac 和 Chromecast 连接在同一个 Wi-Fi 网络下。有时，企业级网络或访客网络会阻止设备发现。尝试重启路由器或切换至个人 Wi-Fi 网络。

Q2: 投屏时画面有延迟或卡顿，怎么办？

这通常与网络环境有关。建议靠近路由器，减少墙壁阻挡。在 JustStream 的设置中，尝试将输出画质从“自动适配”手动调整为“高清 (720p)”，这可以显著降低带宽占用，提升流畅度。

Q3: Subtitles not showing after loading?

Check if the subtitle file name is exactly the same as the video file name (e.g., video named movie.mp4, subtitle named movie.srt). Also, in JustStream’s subtitle settings, confirm that the “Show subtitles” option is enabled and try adjusting the font size and color.

Q4: Why can I only see the screen cast but no sound?

Make sure that the Mac’s system audio output device is set to “JustStream Audio”. In “System Preferences” > “Sound” > “Output”, select JustStream. Additionally, some older TVs may not support audio return through their HDMI ports. Try changing the HDMI port.

Q5: Do I need to allow it when installing?

This is normal as we are a third-party distribution channel. Follow the installation instructions and manually allow it in “Security & Privacy” under “Allow apps from this developer” in “System Preferences”. Our activation versions have been thoroughly tested and are virus and malware-free.

Q6: Can I upgrade to the latest version with the activation version?

It is not recommended to use the automatic update feature within the software, as this may cause the activation to fail. If you need the latest version, please check our website (LoveMAC) for updates. We will provide the latest activation version download as soon as possible.

Q7: Does JustStream support AirPlay?

JustStream mainly focuses on the Chromecast and DLNA protocols. Although it supports Apple TV, it is recommended to use the built-in AirPlay feature of macOS for a better experience. JustStream’s advantage lies in connecting non-Apple ecosystem devices.

Q8: Does the screen need to stay on during screen casting?

By default, screen casting requires the screen to remain awake. However, you can select the option in JustStream’s menu bar to allow “Continue playing when the screen is off”. This way, even if you close the MacBook lid or the screen enters sleep mode, the screen casting content will continue.

Mastering the following Mac universal keyboard shortcuts can significantly enhance your operation efficiency when using JustStream for presentations or watching videos.

Seven, Tips and Practical Cases

Knowing how to use the software is not enough; mastering some advanced techniques can maximize the value of JustStream. Here are some practical experiences we prepared for you.

Tips 1: Create a Personal Cinema Experience

You can use a MacBook to connect to a projector in your bedroom. First, set JustStream to the “Extend Display” mode, so the TV or projector displays a separate desktop. Then, drag the video player window to the extended desktop to play in full screen. In this way, your Mac main screen can continue to browse the web or handle work, truly being mutually exclusive.

Tips 2: Wireless Presentation in Corporate Meetings

In the meeting room, you no longer need to rely on HDMI cables. Open JustStream, select the large screen TV in the meeting room. During the presentation, use the “Advanced Control Options” of the “Mirroring Function” to enable the “Mouse Click Effect Capture” feature. This makes it clearer for attendees to see your focus points, enhancing the professionalism of the presentation.

Tips 3: Create a Dedicated Background Music Player

Utilizing JustStream’s playlist feature, drag your hundreds of lossless music (such as FLAC format) into the list. Connect your smart speaker or TV at home to enjoy uninterrupted background music playback. Since JustStream supports background running, you can even use your Mac for other tasks while playing music, making it very efficient.

Tips 4: Practical Cross-Platform Format Compatibility

Assume you downloaded a Blu-ray original disc movie in MKV format, but your old TV doesn’t support that format. No need to use third-party transcoding software; simply drag the MKV file into JustStream. The software will automatically real-time transcode to the TV-supported MP4 format and cast play. According to our tests, in an M1 chip MacBook Air, converting a 10GB 1080p movie, the CPU usage remains around 15% at most, almost feeling no heat.

Eight, Summary

It solves Mac users’ pain points in sharing content across different devices through its simple design, wide format compatibility, and deep optimization for Apple Silicon.
