I visited my local Apple store and checked out their latest offerings and spoe to them about my Mini Issues under Mavericks.
I was told downgrading OSX to an earlier release might be a solution, but I'd have to wipe my HD to install everything clean.
Since it's a dual HD System, I'm guessing I could move all the data, pix,music to one drive...and wipe the other///or since my "secondar drive" is basically just for back-up, wipe it, lay a new System OSX on it and use it as a newboot drive.
If I need to, that's a decent option.
Expanding Ram: Cheap enough, it's always nice to have a little extra headroom.
BUT the Mini's at the Apple Store were running Mavericks just fine with no delays, no problem. And when I checked their available Ram, they were running with 4GB just fine.
So I am still not sure my issues are all Ram-Related.
It's a 4+ year old System, seems to be working OK now, and as long as I don't run more than 2-3 full Apps, may still have some life left. I blew out a some logs and other files, found an attached external drive wasnt working right, unplouuged it, did some Disk Utility Permission/Verify runs on the Mini's Intyrenal Droves and the Icon Bouncing, Beach Balls have stopped. Hopefully it'll last. Ram is cheap enojugh, I might upgrade to 8 Gigs at some point too just to increase the headroom a bit.
Help/Advice Appreciated
