Computer Help and Support

Mac is easier after adjustment. I use all four operating systems, Windows, Linux, ChromeOS and Mac OS. Mac was my favorite for years, but I've drifted into the windows sphere for most of my computing, mainly as I'm frugal and better selection of used items, and tons of free or affordable software. Support is much harder on windows as everything is more hidden and has moved around over the years, settings wise.
Main difference with Mac, is the two Control and Command (apple) keys, but the settings area is way simpler and up in the top left apple menu.
I personally like putting the dock on the left always on, no magnification. If you want to lock an app to the dock just grab it and drag it, that fixes it.
FYI you can dual boot with windows, but it will crowd your hardrive. Also a wireless mouse might help at times.
Come back when you have questions.
