Macos High Sierra is a pretty stable system from all points of view. Both performance and security. But in the interaction with some applications installed on the system, we cannot say that we are away from strange things.
Lately some users reported strange problem. issue many empty folders with strange names in the root of the Mac hard drive. Macintosh HD by dafault.
As far as it seems, this problem would have arisen after upgrade to macOS High Sierra 10.13.3 (17D47), but we tend to believe it was just a coincidence.
It is clear that the name of the folders have no relevance, they have quite "bogus" names. Most likely, not the maccos operating system is responsible for their appearance, but an application that writes on the hard disk with names. But it is not known for what purposes.
The only way we can find out what application is responsible for creating these empty folders with strange names, is a run o command line by which to see in the processes and applications that write data on the hard. Remember, however, that the control line is not indicated to be allowed to run too long. The file created by this order line can be quite volume.
How can we see what application or operating system component is writing data to the hard disk and are they
1. We open Terminal and we execute the following command line:
sudo fs_usage -f filesys | grep write > write.log
Enter your user password system and press Enter. The file "write.log"It will be accessible to the location where the order line was executed. In our case in" Downloads ". You can choose that it is in .log or .txt format. If you want to open it with TextEdit, replace the termination .log cu .txt.
2. Ctrl+C Stop the control line, then open the .log file and look for the name of a folder that was created while ordering in the terminal.
Here's what the command line looks like in the terminal and an output in the Write.log file chosen by us as an example:
Another way would be to check the integrity of the maccos operating system and see if there are applications that have anomalies. In this sense we recommend the application EtreCheck. You can download it for free from etrecheck.com And it helps you to identify the serious MacOS problems, possible adware applications and give you direct access to the Apple support community.
These folders with strange names can be written by hack applications installed on macos, antivirus software running a wrong process or even a virus.
