Many of us are using MacBooks, Mac Minis and iMacs and with the new Apple Silicon M1 (and M2?) chips Apple will only get stronger.
So here are some totally free useful apps that you may not know about.
Highly recommended!
A great tool to maintain your Mac, tweak some settings. Multiple versions from Monterey back to Jaguar!

OmniDiscSweeper Awesome utility!
Scan your hard drive for unwanted files and reclaim space!

A fast, easy way to open zipped files.

Free open source image editor still going strong after a quarter of a century!

Lastly, VLC plays any file you throw at it - multimedia files as well as DVDs, Audio CDs, VCDs, and various streaming protocols

ONE MORE THING
You might have seen the fliqlo screensaver in this post's thumbnail and also numerous Instagram and Pintinterest posts.
It's also free (although if you can it would be nice to tip any of the creators!).

As usual put any other great free Mac software recommendations in the comments!
