Question:

Question: EtreCheck says /etc/hosts file is Corrupted

I found an old post about the same problem and followed the reply of Linc Davis.

Answer:

Hello WALTER-MILANO-ITALY,

I'm sorry, but there is a bug in EtreCheck regarding the hosts file. It incorrectly reports the file as corrupt if there are over 10 entries. This will be fixed in the next version. It would have been better to have asked privately or post your EtreCheck report. You have no idea what some random script on the internet is going to do. In this case it has exposed your piracy of Adobe apps. EtreCheck tries hard to hide that kind of personal information. But with added complexity sometimes comes bugs like the erroneous corrupt flag.


It looks like you had a kernel panic the last time you restarted. Do you have any panic reports in Console.app? EtreCheck tries to extract pertinent information from panic reports, but in rare cases, the reports are missing or incomplete.


Maybe run EtreCheck again the next time the machine misbehaves. Ideally, run EtreCheck during the anomaly or shortly afterwards.

If there is a specific problem in how your mac is working, please tell us. Otherwise, don’t worry. If you start looking at all the stuff you posted, you will find a lot of stuff that you don’t know about and it is meant to be there to make your system work as designed. There is no good reason to start digging through all that just because. Enjoy your mac.

The kernel panics could be, as the report suggests, caused by hardware; but it may also be software.


I noticed that the transmit and parallels kernel extensions are very old. I suppose that your version of Parallels does not work on High Sierra at all. You should uninstall it, as per the developers' instructions, or update to a current version. Same with Transmit.

There’s more to the conversation

THANKS LUIS.

Sorry, I did not send all the informations.

Unfortunately there is a problem, and that is why I used Etrecheck.

My iMac had problems since several months: freezes, restart, sometimes with fan at full speed. One or two controls at Genius Bar did not find any problem. There are some posts here also.

A couple of month ago I formatted my HD and reinstalled al from scratch: I never did it in the past: I used to "copy" all of my HD from the old Mac to the new-one simply wit MigrationAssistant and this at any new Mac from 2003 until now.

After formatting and new installation there was a great improvement but now I still have some Rebots.

I will try to post the full Etrecheck Report

The kernel panics could be, as the report suggests, caused by hardware; but it may also be software.


I noticed that the transmit and parallels kernel extensions are very old. I suppose that your version of Parallels does not work on High Sierra at all. You should uninstall it, as per the developers' instructions, or update to a current version. Same with Transmit.

Hello WALTER-MILANO-ITALY,

I'm sorry, but there is a bug in EtreCheck regarding the hosts file. It incorrectly reports the file as corrupt if there are over 10 entries. This will be fixed in the next version. It would have been better to have asked privately or post your EtreCheck report. You have no idea what some random script on the internet is going to do. In this case it has exposed your piracy of Adobe apps. EtreCheck tries hard to hide that kind of personal information. But with added complexity sometimes comes bugs like the erroneous corrupt flag.


It looks like you had a kernel panic the last time you restarted. Do you have any panic reports in Console.app? EtreCheck tries to extract pertinent information from panic reports, but in rare cases, the reports are missing or incomplete.


Maybe run EtreCheck again the next time the machine misbehaves. Ideally, run EtreCheck during the anomaly or shortly afterwards.
