BlueTooth doesn't work with OS Mavericks.

I could definitely use some help. I'm just new enough to OS X to not be sure where else to post this.

My Logitech wireless keyboard and Microsoft wireless Microsoft mouse worked fine. The mouse still does, I fact. Recently I had to recharge the keyboard's battery. After reinserting the charged batteries my 2012 Mac mini refused to recognize it. I've done all the obvious stuff I can think of. Once, BRIEFLY, the Mac recognized the keyboard for a flash but it disappeared. The keyboard still works fine with my iPad. I bought a new keyboard and the Mac doesn't recognize it either. I just get the little spinning wheel -- not the color pinwheel.

Suggestions? Thanks in advance.

This worked for me, reboot didn't help. Shut down and restart brought it all back to life.

I had the "bluetooth not available" message. My mouse worked and keyboard didn't.

Thanks for the help.

Had the same problem.

What worked for me was to shut-down the computer, NOT re-start.

I can't figure why re-starting never worked. I tried it many times. But then I read one post about shutting it down instead and enphasizing not to re-start and decided to try. It worked!

I experienced the same issue, BT not available.

Finally found a post that basically said,

"turn the computer off and then on again.
I would add disconnect the power cord for three minutes.

I should have just followed "Ockham's Razor".When i hit an

issue, ie,,trouble shooting Bluetooth, I attempt to remember to follow
Ockham's suggestions,

Ockham's razor from William of Ockham (c. 1287 – 1347), and in Latin lex parsimoniae) is a principle of parsimony, economy, or succinctness used in problem-solving. It states that among competing hypotheses, the hypothesis with the fewest assumptions should be selected.

If you know about Ockham's razor, it's always good to

read the principle. I should wear it around my neck.

After you open it, do a "Rebuilt Cache"

Wait a little that the program check !

When it's finish, the bluetooth is working like it does !

Hope that it helped you !

My fix...

I wasn't even trying this but somhow helped.

I was about to o a CMD + R but first I decided to join my family in my living room and do it while wathing a movie.

So I turned it off and I unplugged everything. After doing a normal reboot everything was fine!!

Thats it, maybe the "unplugging" is what completely clrears somen settings.

Just try it, it wont hurt.

I tried everything and this problem just kept re-surfacing.....Until now.

I turned off the sleep settings in powersaving mode completely (set to NEVER).

The issue has gone away completely. All bluetooth tools now work fine.

I tested this by turning power saving back on..... sure enough the issue returned.

Good luck

Worked for me. The solution supplied by wealsung.

Thanks.

Same issue.....I tried this simple sleep fix and just like magic, it worked! Thanks sooooo much!
