MacOS 10.15 Catalina/ 11 Big Sur, additional Security and Privacy requirements for Mac Streamer and Mac Business App


Note: On Apple Silicon devices, streaming audio is not supported due to the driver is not able to be installed. We're currently working on it, but the timeline is not set for implementation.

Apple 於 2019 年 10 月 7 日發布了 macOS 10.15 Catalina。此一新版本具有更嚴格的安全要求,需要顯性權限才能允許應用程式進行控制。

For Mac Streamer v3.3.2.0, these are the additional Security and Privacy settings that are required to be set to allow the Splashtop software to provide remote access:

需要勾選系統偏好設定/安全性和隱私權/隱私權下的四個選項,遠端連線才能正常運作。請注意,這些安全性設定不能遠端設定 - 必須先在本機變更這些設定,然後才能建立遠端連線。

Also, please note that if these are already checked, uncheck and recheck them. Users have reported that this action prompts the permissions to reset if they weren't working before.


  1. 存取範圍 (影響控制項) – 該選項適用於 macOS 10.14 Mojave,需要勾選該選項以啟用遠端控制。這一點與 10.15 相同。若 OS 升級時,您已在 10.14 版勾選該選項,則無需在 10.15 版再次進行相同設定。若在 10.15 版安裝新的 Streamer,則需要勾選此設定,以啟用遠端控制。
    • 若升級到 Catalina 前已在 Mojave 完成此設定,則可能需要刪除 (-) Splashtop Streamer 的輔助功能設定,然後重新新增 (+) 並再次勾選。
  2. 全機存取 (影響檔案傳輸) – 該選項適用於 macOS 10.14 Mojave,但無需勾選。現在,在 10.15 版則必須勾選,以使用檔案傳輸功能。如未勾選,則遠端 Mac 的檔案/資料夾將不會顯示在檔案傳輸視窗中。
  3. 螢幕錄製 (影響遠端連接) – 該選項不適用於 macOS 10.14 Mojave。現在,在 10.15 版請勾選該選項,以建立遠端連線。不然您將無法建立遠端連線,並且會在 Streamer 電腦跳出一個警告視窗 (通知您無法遠端設定此視窗):
  4. Microphone (affects sound stream) – The option is available on macOS 10.14 Mojave and needs to be checked to stream sound over remote connection. This is the same on 10.15. However, Soundflower does not work on 10.15 - you can’t stream sound even when checking Microphone if still using Soundflower.

For audio, please note: On all MacOS versions, remote sessions connecting to a computer at the pre-login state (when there is no user account that is logged into) will not be able to send audio over the remote session. To fix this, log into a user account on the computer, and then disconnect the Splashtop remote session, but do not log out of the user account. Then, when you reconnect, you'll hear audio.

Second note: Most of these settings only apply to the user account on which they are granted. If you have multiple user accounts on a device, you will need to grant permissions on each.

Third note: Remote connections cannot work at the Mac login screen with Mac Streamer v3.3.4.0 and macOS 10.15 Catalina. The team has found a resolution for the issue - the solution is released in v3.3.6.0.

Fourth note: On Apple Silicon devices, streaming audio is not supported due to the driver is not able to be installed. We're currently working on it, but the timeline is not set for implementation.

Mac Streamer 版和更新版本必須使用與上述相同的設定。另外:

  • With Mac Streamer v3.3.4.0, there is a helper upon new installations which guides users to check these four options. This helper will not pop up in upgrade cases (there is a badge button on streamer UI to manually open the helper).
  • Soundflower 致力於透過 macOS 10.15 Catalina 提供影音串流功能。
  • 遠端存取可以在登入畫面中連接 macOS 10.15 Catalina。

  1. 檔案和資料夾 (非全機存取) (影響檔案傳輸) – 該選項不適用於 macOS 10.14 Mojave。在 10.15 版必須勾選該選項,以使用檔案傳輸功能。如未勾選,則會跳出一個對話框,要求您在存取本機每個資料夾/檔案時設定系統偏好設定。
  • 使用 版時,安裝的同時會提供一個輔助方法,指導使用者檢查存取範圍選項。
