The first question that PC users ask when switching to Mac what is the equivalent of Windows Explorer on a Mac? The equivalent of Windows Explorer on a Mac is the Finder app.
The truth is that Finder is not bad or weird, you just need to learn to use it properly, like a Pro. If you browse Apple forums you will often see questions like “is anyone else is frustrated with Finder” and “Why Finder is so weird”.
If I have to name number one application that was driving me crazy when I switched to Mac the Finder would be the top contender.
