Hello OceanDrifter,

Thank you for this link which therefore indicates the solution to follow:
• install the tool Malwarebytes anti-malware (free) in your "Applications" folder
• launch the tool and if the scan discovers any malware, then you need to activate the deletion option and then restart the Mac (Apple menu () then "Restart")

Good evening Ritchi, good evening Kuona, I cannot insert an image because I am not a member.
I will describe the message:
A plain white error message rectangle.
At the top it says:

Error while installing
Below:

Expecting value: line 1 column 1 (char 0)

Below are two buttons:

Cancel OK

The OK button is blue

The message appears immediately after the installation of Finder.
Whether I click OK or CANCEL does not change the functioning of the Mac.

Thinking about the recent changes to my computer, the only change that happened simultaneously and two days prior is the discovery of a new interface for my Orange email account, with the disappearance of the option to refuse cookies from Orange and their partners,
an option that was offered to me every time I opened my email.
It is worth noting that I use Ghostery and Adblocker on Safari
there you go, I don't know if we can move the issue forward with this information and I thank you.
Have a good evening
Thank you

Hello, I fixed the issue by following Oceandrifter's suggestion. (thank you).
I went for a look at the Apple forum below:
https://discussions.apple.com/thread/252501431?answerId=254724336022&login=true
(English forum)
It turns out that many of us have this message at startup.
Apple tried for a while to justify this problem by suggesting a hardware issue... It is clear that the problem is not there since we don't have the same machines.
So, I installed a demo version of Malwarebytes and started hunting for malware, cleaned up, and then ran CCleaner and Onyx.
Finally, I checked the permissions with the Apple tool and verified my settings in Safari and Chrome.
The message has disappeared and my computer is behaving much better.
It was indeed a malware or relatively spying software.
Other participants in this forum seem to have cleaned their computers with other software. The problem has been identified for some time now.
If you use Malwarebytes, make sure to download the version corresponding to your version of macOS.
Below is a link where you should find the correct version.
A big thank you to you for the help and responses.
Have a great week everyone.

Hello,

A photo or screenshot might be very helpful if there is text preceding this error.

Just in case, here is some help on:
- How to take a screenshot on Mac
- How to insert an image into a discussion
Note: Select the interesting part and not the entire screen, otherwise the image will be too large and the texts will be unreadable.

Thank you Kuona for this screenshot.
Would you also have the same ad blockers (Ghostery or Adblocker)?

Hello everyone.
I may have found a solution to solve our problem.
I'm testing it today and I'll keep you posted.
Have a good day.

Exactly the same thing appeared two days ago on MacBook Pro late 2011, Sierra 10.12.6. ???
Thank you for your help!

Good evening,
The same issue appeared a few days ago on an iMac 2013 running 10.10.5.
No recent actions on this device nor any ad blockers.
An external factor?

I use an ad blocker on Firefox.

And here you go !
