I love Logic Pro X, it’s the main reason I have a Mac. There really is nothing else like it.

Honestly I feel like Logic Pro is some of the most impressive and user-focused software Apple is making these days. It's such a relief that Apple still sees its professional Mac apps as a priority for the company.

I never understand though why MacRumors relegates Logic Pro announcements to the Mac blog when every tiny iOS announcement gets front page treatment.

UI of Logic out of place now with dark mode. Needs darkening.
This seems to happen with every update. I believe the Logic team is still based in Germany, and it's always seemed that they're not really included in the loop about upcoming OS features. I imagine in the next update we'll see Mojave feature support.

Cheers guys I got mine.
Really?! Mine's still on 10.4.1.



Ah man don't tell me I'm gonna have to delete it and redownload it to get an update. I've looked at the release notes and it was 17 hours ago.

Are you on Mojave?

EDIT: I went to the "Updates" tab on Mojave and pressed CMD + R a few times. Refreshed the search and it's there, if anybody else is having the same problem. Didn't work by CMD + Q'ing & reopening, but CMD + R's your girl.

Thanks for the heads up guys, wouldn’t have known otherwise.

Sadly, not showing for me as of yet... I was hoping the App Store on Mojave would be a bit faster. Still saying no updates. Even searching it in the App Store just says “Open”.

Waiting just a few minutes for an update to become visible is like waiting for a pizza when it’s passed the expected delivery time. It’s never usually long from there but boy is it frustrating.
