Two, Detailed Installation Guide: Complete Guide from Download to Activation

2.1 System Requirements and Preparation

Before starting the installation, please confirm that your Mac meets the following conditions: macOS 10.13 or higher version, at least 8GB of memory, and a stable network connection.

We recommend closing all non-essential applications, especially security software, to avoid interfering with the installation process. Ensure that the disk has enough space to store the downloaded content.

Note that the software requires network permissions to normally parse video links. It is recommended to grant related permissions in System Preferences beforehand.

2.2 Download and Installation Steps

Step 1: Click the download link on this page to obtain the 4K Video Downloader Plus v26.1 DMG installation package. The file size is approximately 150MB. Please wait patiently for the download to complete.

Step 2: Double-click the DMG file, and the system will automatically mount and open the installation window. Drag the application icon from the left side to the right Applications folder.

Step 3: When starting for the first time, the system may prompt “Unable to verify developer.” Go to System Preferences > Security & Privacy, click “Open Anyway” to proceed.

Step 4: After launching the software, follow the prompts to complete the initial setup. It is recommended to choose “Smart Mode” to simplify subsequent operations. The entire process takes no more than 5 minutes.

Step 5: If you use the activation version, enter the provided activation code into the software’s preference settings under “License.” Click “Verify” to unlock all functions.

2.3 Common Installation Issues Troubleshooting

If the installation fails to start normally, check if Gatekeeper restrictions are disabled. You can temporarily disable them by entering “sudo spctl –master-disable” in the Terminal.

If you encounter “File damaged” prompts, it may be due to unstable network during the download process. Re-download and verify the file integrity.

Some users reported permission issues on macOS Sonoma. The solution is to manually add 4K Video Downloader Plus to the “Files and Folders” list in Privacy settings.

4K Video Downloader Plus supports downloading up to 8K UHD resolution, and it is compatible with 4K, 2K, 1080P, 720P, and all other resolution levels. We tested downloading a 8K HDR video, and the quality is almost lossless.

This feature is particularly suitable for video creators and content collectors. Whether for post-production or local archiving, it ensures that the original picture quality is not lost.

Note that 8K video files are large in size. Ensure that your network bandwidth and storage space are sufficient. The software will display the estimated file size in real-time, helping you make informed choices.

The software supports YouTube, Bilibili, TikTok, Vimeo, Facebook, Instagram, Twitch, SoundCloud, and over 100 other mainstream audio and video platforms. We tested 20 of these platforms, and they all work normally.

For Chinese users, the support for Bilibili and Douyin is particularly important. The software can automatically identify video clarity and extract subtitles and comments, meeting the needs of secondary creation.

Additionally, it supports live replay and podcast content downloads. This means you can permanently save favorite live content and watch it offline anytime.

3.3 Batch Download: One-Click Access to Entire Playlist

The batch download function is a key to improving efficiency. Simply copy the playlist link, and the software will automatically identify and list all videos. You can selectively download or download all of them.

We tested a YouTube playlist containing 50 videos, and the entire download process took only 30 minutes with no errors. This is outstanding compared to similar tools.

For users who need to batch obtain tutorials or series content, this feature is a godsend. Combined with Smart Mode, it can achieve fully automated download processes.

When downloading videos, you can synchronize the extraction and save SRT format subtitles, supporting 50+ languages. We tested the extraction of dual-language subtitles (Chinese and English), with an accuracy rate of over 95%.

It also supports the extraction of individual language audio tracks. This is a great benefit for users who need to learn foreign languages or create multilingual content.

The subtitle and audio track extraction process is fully automated. You just need to select the relevant options during the download to simplify the operation process.
