/maybe means if it is red and yellow.  both bad.  (wld guess red worse.)  mine yellow.  high memory pressure. 



Tip # 3. Clean up your Desktop

—CLEAN UP DESKTOP   *Thing is, your macOS was designed in a way that it treats every Desktop icon as a little active window. // !!!   huh!  //  I hope this d n also mean apps in dock.  no, right?   // 
The more icons, the heavier memory usage on Mac.  // mine are almost all text edit but still.  and some pics, not big files, pngs  old pics less high mb, grab screenshots.  wld just mean active windows = running the app Preview ?

////////// so, am clearing.   new folder   then will put in Documents.   or on own in dock:

 ** Thing is, your macOS was designed in a way that it treats every Desktop icon as a little active window.

Tip # 6. Free up disk space if Mac is low on memory
The available space on your Mac’s drive translates into virtual memory. This comes to save you when you’ve run out of physical RAM. So now your computer relies on your hard drive space to keep your apps going.
The classic geek rule of thumb holds it that you should keep at least 20% of disk space fn your startup drive.
   keeps your Mac speedier.


But here’s a simpler solution to save your time — clean up your drive with CleanMyMac 3. The app is free to download. Many users recommend it as an excellent way to free up more space because it automatically searches for large & old files and shows everything you can safely delete. Interestingly, it finds about 74 GB of junk on an average computer.
// ok I guess never used this app, so maybe try.  shows wh can safely delete.   shows big files  probbbbably  iphoto.
had used various well maybe two disk cleaner programs, d n like…  





What else you can do to minimize memory usage on Mac


— Replace AdBlock (very memory-demanding) with a lighter extension
// oh... (but is it not saving fr running big busy ads?    ??   (maybe not)       <<<

—Keep fewer opened tabs in browser  /welll this is wh I want to have room *for*
