    I monitor my RAM usage with Memory Clean 2. Promptly on restart, my ram is 50% used, so 8 GB free. Anyone know why this would be? Using memory clean doesn't provide any gain.

    I'm running the same installation I had on my macbook air with 4 gb ram.

    The operating system caches things in memory. There’s no reason to be concerned. I’d suggest ignoring Memory Clean and just using the computer. Unused RAM is of no value.

    Yeah I wouldn't worry about it pal, things only start becoming problematic when your mac starts page filing, but as chrfe states, unused RAM is of no value.

    I wouldn't trust memory clean, nor would I use it or other utility.

    If there are /various/swap files then you are paging.

    Otherwise the 8GB actually sounds normal and good.

    I bet if you look at your MacBook Air with 4GB of RAM, you will notice a lot more compressed memory then you 8GB machine does. macOS like many *NIX's will cache a lot until its forced to slim the caches down for real programs running. It's completely normal.

    I found memory cleaners to be useless. They do seem to free up ram immediately after running the program but after 30 min, it goes back to how it was before meaning it's basically same w/ or w/o.

    Besides, as long as there is no swapping, you want the os to use as much available ram as possible. Free ram is basically wasted if it is not being used.
