I'm using mid-2010 13' one and yesterday I have upgraded my ram to 8gb, installed 1TB hdd and swap odd to sad.

I have installed fresh mavericks on my fusion drive and the system seems to already know some networks like my school's, home, girlfriend's house etc. :confused:

I would like to know how newly installed fresh OS X knows wifi profiles and passwords.

* by the way it's macbook not mabook..
 
I believe that this data is stored in PRAM. I've experienced the same thing so it's not just you :)

It's important to remember to clear PRAM when you sell a computer!

but it didn't remember any of the networks before??? for example when I installed SL on a partition.

Thanks anyway that explains what had happened :)
 
I think it has to do with iCloud Keychain if you have that enabled. I just recently got my first Mac and I noticed that it had a list of all the networks my iPhone had previously connected to.
 
The guy above this is right. Its most likely iCloud Keychain so if you have an iPad/iPhone, it has probably got your networks from iCloud

I don't believe it is. I created a Mavericks USB stick and booted from it, and it connected to my Wi-Fi network from the installer. I didn't have to enter any details whatsoever, Wi-Fi or iCloud.

Maybe it's a combination of either/or? I'm not familiar with the PRAM at all but your scenario wouldn't make sense in my case since my Mac was brand new yet it already had a bunch of WiFi networks saved. So maybe the info is stored in multiple places?

Could be! Otherwise I blame ghosts :)
 
It's all stored in icloud. If you go into your network settings and poke around a bit, you'll find every network your Apple devises have hooked up to there. Even when you found free WiFi in the middle of Nevada.
 
iCloud? PRAM?
I believe it is iCloud since my SL on a partition of my hard drive does not recognise any of the routers.
Many thanks guys!
 
Definitely iCloud. As a poster mentioned above, their laptop was new, as was mine. Had to put the passcode for initial setup, but after my Apple ID was entered, going into WiFi networks presented a list of every network my iPhone/iPad has connected to, along with saved passwords. Pretty handy! Just a shame it doesn't seem to be a feature on iOS devices (yet).
