Similarly, it's conceivable that your media player is too old or outdated if QuickTime Player cannot open downloaded MP4 files on Mac. Hence, you may try to update the player to the most recent version as soon as possible.
There are mainly two ways for you to update or reinstall the Quicktime player:
- Uninstall the QuickTime Player, download it from the official QuickTime download page for Mac, and install it on your Mac computer.
- You can also determine manually whether or not the most recent QuickTime updates are accessible. Choose QuickTime Player > Upgrade Existing Software from the QuickTime menu. If any updates are available, upgrade by following the instructions. Now see if MP4 files can be played on QuickTime player.

Whether running Windows or macOS, a computer constantly in use creates temporary and cached files; these details can cause various problems, such as QuickTime not playing MP4 on Mac. You only need to delete the temporary or recent files to solve the problem.
Here are the steps of how to find the temp folder on Mac and delete them:

Step 2. Right-click on Go > Go to Folder in Finder.
Step 3. Type ~/Library/Caches/ into the search box and press Go to execute the command.
Step 4. Check all the produced temporary files saved on your Mac in the opened window.

Step 3. To add "Macintosh HD" to the list, select it.
Step 4. Click "OK" next to the cautionary message. Your recent items should now be empty.
This option disables Spotlight on your Mac, so you won't be able to search for files and folders on your hard drive if you select it. In that situation, the recent items in Finder will be removed after reindexing.
Choose a different media player installed on your Mac device if the approach above does not work. You can utilize VLC and Mplayer if your QuickTime media player has a playback issue.
You can use the following procedures to play your films on VLC rather than QuickTime:
Step 1. Download and install VLC Player on your Mac. Then, right-click the video file you want to play in VLC.
Step 2. Choose "open with" from the options, and a dialog box with "VLC Player" will display.
Your video is prepared to be played in the VLC Media Player once all the steps have been followed.
When digital videos are compressed, a codec algorithm connects distinct multimedia streams, such as audio and video. Codec is also used to transform digital data into a format that can be read. So, there's a potential that your Mac won't be able to read this video's codec if your file doesn't open in QuickTime. You can use the steps below to determine the file's codec:
Step 1. Choose "display movie inspector" from the Windows tab of the opened video file.
Step 2. A dialogue window will appear displaying the video's source, format, frame rates (FPs), size, data size, and data rate. It would be best to watch for "Format" to view all the codecs in your media.
Following is a list of all the audio and video codecs that QuickTime supports:
- Video Codec: MPEG-4 (Part 2), H.264, MPEG-2 (OS X Lion or later), H.263, H.261
- Audio Codec: HE-AAC, AAC (MPEG-4 Audio), Apple Lossless, MP3
See if any of these formats are present in your video. If not, turn on the necessary Codec support. Also, you can download third-party applications to help QuickTime recognize all audio and video types.
Try converting the original video into an encoding format that the QuickTime player supports if your file won't play on the QuickTime player. Renaming the file will allow you to modify the extension. For example, change the file's name to end with.avi instead of the.mp4 extension.
You can also download additional third-party applications that can convert videos to a format compatible with the QuickTime player.
You could run into issues like "MP4 not playing on Mac" when watching videos on a Mac. The good news is that damaged or corrupted videos may be fixed using simple manual procedures or automated file repair programs like EaseUS Fixo Video Repair, even if there may be several causes. If the manual approaches don't help in your case, grab the free trial of the video restoration program by clicking on the download button below. It shows the preview of the corrected video.
