Hello Rodolfo Barbosa,
Welcome!
(Additional to richbuff's post)In your case, did the issue pre-exist upgrading to KIS2020?
In KIS Reports - are there any events matching "Mac App Store access blocked" ?
Have you:Uninstalled KIS, shutdown MAC completely using: Apple key→Shut Down
Restarted MAC, downloaded new KIS2020 exe, reinstalled, shutdown MAC completely using: Apple key→Shut Down, restarted MAC, rechecked?
Have you tried kenj's "KeyChain Access "fix"?
Please post back?
Thank you:pray_tone3:
Yes. I was using KIS2019 before and starting on October the 3rd I was unable to access iTunes Store and App Store. Actually, on October the 3rd I identified the issue, I'm not sure since when it was happening.
No. It has not.
No. I have not.
Yes. It was the first thing I tried when researching about the issue.
