Mac OS is almost virus-free but sometimes it may happen that you are not able to access any of the media files especially MP4 files due to any reason. The reason can differ from situation to situation but the major reason behind it is file corruption. There are many scenarios which are responsible for MP4 file corruption on Mac OS. Some of the most common scenarios are mentioned below:
Changing file extension: File extension plays a vital role in reading and opening a particular file. Sometimes it may happen that you want to convert particular MP4 file into some other file format by changing its file extension manually or by using any third party software that provides the facility of changing file extension. But you never know whether the method you are using for changing file extension is appropriate or not. In the course of conversion process if something goes wrong then there is lot of chances that your MP4 file will get corrupted.
Disk failure: All your files, data and documents get stored in your system hard disk. Media files are very sensitive files compared to other files. Therefore, if your system hard disk gets damaged due to any reason such as scratches in hard disk, virus attack etc. then your stored MP4 becomes inaccessible due to file corruption. Disk failure is a big threat which leads to system malfunctioning by corrupting each and every stored important files and documents.
Virus attack: Even though Mac OS is almost virus-free it has been observed that in many scenarios it can also get affected by some of the external threats. Viruses have the capacity to destroy and damage each and every single file stored in your system. Once your MP4 file gets infected by any external threat, then there are lot of chances that your file will get corrupted. Virus will directly attack the file structure of your particular MP4 file. Its attack is poisonous as it slowly and steadily damages the whole file within a short span of time. Due to this your file will not open and becomes unusable for further use.
Abruptl system shut down: If your system gets shut down abruptly at the time when your MP4 file is in playing mode or at the time when you are transferring a particular MP4 files from one storage device to another then there are chances that your file will get damaged and becomes corrupted severely. System shuts down abnormally only when there is power fluctuation or operating system crashed or when some dangerous external threat attacks your system. Once your MP4 file gets corrupted, then you will not be able to access it in future until and unless you fix it.
