Safari will not delete Cookies & websites data...
I will appreciate some help to find the solution....
My son iMac (27inch, late 2012
Processor 3.4 GHz Quad - Core intel Core i7
Memory 32 GB 1600 MHZ DD3
System Mac OS Catalina 10,15,2
Safari v. 13.04
When Mojave was installed in the iMac the problem started
We upgraded to Catalina 10.15 then 10.15.1 and now 10.15.2
In the old versions of the systems and Safari old versions this problem was present after all the upgrades is still the same without change.
The problem is: Safari will not delete cookies and Websites data.
Under SAFARI MENU you can see in the picture down.... "Clear History" is in Grey.
If I open "Safari Preferences"and click on "Privacy" and then down in "Manage Website Data" I got a long list that I can not delete with "REMOVE" not wirh "REMOVE ALL" even if I select some or all of them.
My son uses the iMac very little since he use his iPad also but we have not be able to remove this long and growing list of cookies and Websites data.
I have tried to find the answer in this community and applied some solutions as........
Quit Safari
GO to Library/ Safari / Databases / _IndexedDB and delete its contens.
Then Library / Safari / Local Storage and delete its contens.
After this I open Safari and test ...... not Change at all.
The screenshots shows what Safari show me before I try and after I have tried, same pictures.
