So hopefully someone has the answer to this. I installed mavericks on a computer and during the setup i linked it to my icloud. However i thought i messed it up and did a clean install again and reformatted the disk again. However I had a page still open in safari on the previous version and it now shows up in my icloud tabs as if it was left on the computer. I searched the internet for hours with no luck of finding any way to unlink that computer. The main thing is the tabs since i don't think i see anything else from that computer anywhere and it doesn't seem like it has anything stored in the icloud. Is authorizing all computers in itunes going to help? i did enter where it says how many computers are authorized and it says two... which i assume are the mac and the windows partitions .. Is it possible that the other one doesnt come up? The computer is a pc *a hackintosh* if that influences this in any way? [want to try out mac os before jumping ship] I'm sorry if there was a thread like this before but i didn't find in search.Thank you for the answers!
