I'm now the "proud" owner of a mid 2007 7 iMac. It has OS Tiger on it. I just wanted to see if anyone thought it would be worth it to put anything into it. It works fine as a computer, even has photoshop and all the adobe applications on it (from around 2010 of course). Everything seems to work fine except for safari. It will somewhat pick and choose what webpages it will load. It will load a select few from my bookmarks and not allow me to google anything. I accidentally deleted firefox off the computer forgetting about this issue, so I can't confirm if this is just a safari issue or an entire computer issue. Unless someone knows of a way to get an old enough web browser onto an external hard drive/flashdrive to put on the computer, that would be helpful. But my main question is if I'd be able to upgrade the OS to run a newer version. If I'm correct, I'd have to buy a cd of the os, right? Any suggestions or opinions on this whole situation would be greatly appreciated. I just thought it would be nice to have as an extra computer to do homework on and what not. Thanks!
