I had a pc and I ran the ccleaner software everyday. Should I use the CCleaner software on the mac too?
 
No. Because something works well for the PC does not necessarily mean it will work the same way on your Mac. Download and use the free OnyX software instead. It's designed for your Mac and works great. Download from here. Be sure to download the version that's for your version of macOS you're running.
 
None of those cleaner apps are worth anything and some of them do more harm than good. I always recommend people to learn about the system so that they can clean things themselves - if and when you actually need to clean anything.. I've been on Macs since 2012 and have never had to do any type of cleaning.

Another vote for Onyx, it's an excellent system maintenance app.

I switched to Mac from a lifelong usage of Windows for my personal computing back in 2015. I've spent a lot of time looking at what Mac OS leaves behind when you uninstall applications and its handling of "junk" --- and I've come to the conclusion that you don't need a "cleaner" for Mac.

That said, I've found if you wanna get everything during an uninstall - http://freemacsoft.net/appcleaner/ -- I use this to uninstall applications. It doesn't always find everything but it'll try.

Open Finder -- Open the Go menu on the top left, hold down your Option keyboard and you'll see Library appear. Inside here you'll see Application Support. This is where most of the junk lies for applications you remove. Be aware that there can be very vital files here - such as account info for applications uninstalled, etc...

But yeah, I've tried several apps (even the famous CleanMyMacX) and --- it's not needed. The "cache" that Mac uses, if you wipe it out, you'll just burn battery re-creating it after a few days of normal Mac OS usage.

I use CarbonCopyCloner to manage TimeMachine snapshots if I remove large amounts of data I don't want hanging around.

Carbon Copy Cloner is one of those apps that is quite necessary to have. It's good at what it does and can save your backside in a crunch. Malwarebytes and Onyx are other great apps to have on hand.
