So I finally installed Mojave. I had heard that the dark mode was a bit rushed with poorly reused icons and not all the apps having been migrated properly. Some even described it as a student's poor design project. So I stuck with Light Mode. But the problem is that the apps have changed their lightmode palette too .. the background (login for example) is too light. Apps like Safari are far lighter now than in High Sierra. This is bad. Dark Mode is not for everyone, and currently unfinished. The Light Mode is also new and not well done. I wish they had left the option for traditional mode that was refined over many years. Even the background colour picker has lost previous colours that were possible .. grrr!
