Apple

OP for the love all man kind, don't listen to a single person here telling you to install these silly utility tools that make a Mac run more like Windows. Don't get Alfred, or Bartender or apps that give you the "Windows" experience of split screens. It's all nonsense. Your Mac does everything those apps do. You really should take the time and discover what it does instead of instantly installing a lot of BS. Then you'll see why Apple puts so much time into the Mac and MacOS. You'd be surprised everything it's capable of.

The Mac comes with a very good office suite but if you need MS Office then get that. It also has a very good photo editing suit but if you need something more get Pixelmator or PS. If you need to do video editing it does include iMovie but if you need more then install Apple's Final Cut Pro X or Adobe Premiere.

If you want the best adblocker then get WIPR. It's ~$2 USD and it's absolutely the most powerful. It can't get everything but it's better than the other free ones.
