Hi, I upgraded my hard drive to an SSD in my 2008 MBP and did a clean install of SL on it. I then installed some apps with no issues, but when trying to install MacTex-2007 (a latex distribution) I encountered a problem. The installation program launches and I can go several steps in, but when I have to select the packages to be installed all of them are greyed out. So I can't install this app at all. I had previously installed this app in my older hard drive, so I know that it can be installed in SL. I did a permissions repair on my SSD but it did not help. Any tips will be greatly appreciated! Cheers!
