Apart from the new system update iOS Issued Apple a little while ago and a minor security update for your macOS High Sierra 10.13.4 system. This security update comes almost a month after the release of the hot version of the system itself.
According to the notes Applu is a security update labeled 2018-001 and is recommended for all users because it improves the security of macOS High Sierra. Unfortunately, we don't know the details of what exactly it fixes.
So, if you own an Apple computer, you can update the system normally through Mac App Store and the Updates tab, where you should be offered a new update.
Does anyone know how to fix my Mac not showing/unable to download update? It only shows up when I'm in the American store, but in Czech...
I also hope that they will fix it sometime in the future :D
I already tried to solve the problem before the last update and nothing, somehow it happened Applu didn't work :D but the update via Terminal still works, or I'm posting a link to such a piece of crap here so that it doesn't have to be done manually (or I'd be happy for feedback (and errors) if anyone uses it :) ;))

Also like that. I believe it will be fixed.
