Hey! Basically all of a sudden my mac's software started going all weird and it's been really getting on my nerves. Here is a list of the problems (Sorry if some of them seem minor, they just really bug me) : 1. My applications icon on my dock now opens a finder window, instead of the usual applications window that comes up. 2. I can't copy and paste things, as in, i can't copy anything off the internet or paste something i have copied to the internet, i have even tried various different browsers. I can however copy and paste things in mac word and pages. 3. I can't open itunes or iphoto. A little message comes up saying that it may not work with this version of Mac OS X. Thing is, i updated to Lion when it first came out, and had absolutely no problems then. 4. All of my photos in finder want to open with photoshop as a default. When i click 'open with - preview', the preview icon appears in my dock as active, but no pictures will actually open. 5. The thumbnails of my files and pictures in finder and on the desktop don't show, its just blank. I think that's it, but like i said, i updated to Lion ages ago, and everything worked for ages. I have no updates needed to be updated, so thats not the problem. And other than that, my mac seems to be running fine. I'd really appreciate it if you guys could help me, as im no longer under warranty, and my nearest apple store is about an hour away from me! Thanks in advance! Theo.
