My favorite is macOS Mojave (or newer) because ites with free apps that eliminate the need for me to install any other thread party apps. That means that the apps I use are safe and secure and work seamlessly well in the Apple ecosystem. My best Mac Apps Safari The fastest most safe and secure web browser with enhanced privacy characteristics 1 Password manager (Autofill) is safe and secure Apple has been supplying encryption to its users since the 199s and has been proven to be safe and secure other third party password managers have had security issues and do not have a trillion dollarpany to back them up 1 Pages Numbers and Keynote eliminate the need for office software. I was a big fan of MacWrite back before Microsoft Word ever had a GUI and Pages is a much improved version of it. Textedit is used daily for all manner of notes as an outliner to collect thoughts for website articles as a draft for input into Pages it is so flexible that I practically use to for everything that does not require a spreadsheet. Preview looks simple but is also used on a dual basis to look at PDFs photos etc. and its simple built in editor allows me t do a quick touchup on pictures QuickLook is used countless times every day to peek instantly at files it also has a built in editor that can edit pictures immediately Notes integrates seamlessly with my iPhone and iPad so everything is always up to date everyone all at once its indispensable Messages is not only the only provably safe and secure messaging system its integrated across my iPhone and iPad so everything is always up to date everyone all at once its indispensable iMovie GarageBand Time Machine Automater Xcode etc. The list is actually very long Apple has done an amazing job of slowly but surely building in all the functions we actually need in a simple easy to use way so that we do not have to rely on third party software unless we are doing something professional or exotic. Still Needed Blu-ray player Apple was part of the consortium to support the superior version of Blu-ray (Microsoft was backing the opposing camp with a kludge based on DVD that was not for for the future) so it was a surprise that the the consortium finally released Blu-ray none of theputerpanies could afford a license to include Blu-ray movie playback software (that correct not even Microsoft has Blu-ray playback capability but in many bundles they include a third party player). I do read and burn Blu-ray discs (blanks) on our Macs but have to use a third party app to actually play one of my many Blu-ray discs. 1 GraphViz A viewer for QuickLook 1 Edit feature in TextEdit 1 MacDraw An up to date replacement would be awesome the original MacDraw was extremely useful for those of use who do not need or don't have the skills for a professional illustration package 1 AppCleaner This little app throws away all the little debris that is left behind when an app is thrown into the garbage. It works so well that Apple should just cut this guy a $1 million check and take over ownership of the app then bundle it with macOS 1 Handbrake Handbrake integration into iMovie and Final Cut Pro would be nice. Final Cut Pro works extremely well as is and can be greatly enhanced with Apple Compressor but there are still a few occasions where an old piece of video needs to be transcoded into something modern which is where Handbrakees in. 1 Handbrake is open source so just integrate it exact as is and it will work fine Just add an option to use Handbrake when needed. 1 Completely Unneeded Anti-Virus Anti-Malware Anti-Spyware These are useless apps 1 macSO already proven Anti-Virus Anti-Malware Anti-Spyware built in so there is no need for anything else. 1 Cleaner apps Over the long run they do nothing that is actually useful if there is a problem then just make sure you have at least 2% of the drive free (if not then use the new About This MacStorageManage feature to clean it up) and then if there is still an issue you simply boot up while holding down the Shift key this will purge all the caches and clean the system then just boot up normally. 1 Password Managers Use Apple AutoFill which is more convenient and far more secure. 1 Web Browsers Nothing is as fast and as secure as Safari 1 Cloud Storage Nothing has the integration of iCloud 1 Screen Brightness Manager Mojave has Night Shift which works smoother than anything else I have seen 1
