Why can't I get Execute permission?
Hi, sorry for what may be a simple question, but I'm very new to Macs.
First let me say I'm working on a MacBook Pro with OS X 10.4.8 and I currently have the only account on the machine. I am the sole administrator and the sole account. Yet, when I download some programs, I can't install them. For instance, when I recently downloaded MPlayer, I mounted the DMG file and went to open what seems to me the installer - MPlayer OSX (Universal).pkg - only to have a small icon flash in the dock for a second, then nothing happens. I checked the info for the file, and I only have permission to "Read and Write", and this field is greyed so I cannot change it. The dmg file itself is also "Read and Write", though it is not greyed out. Yet, I still cannot change it because there is no option to execute.
What might be the strangest thing though is that this doesn't happen with all applications. I successfully installed VLC player instead, as well as Firefox and a few others, while a few others have given me the same issues as MPlayer, like an installer from Microsoft to let QT play wmv files (a .mpkg file). The same thing just happened with a bittorrent client I just downloaded - Bits on Wheels. I successfully unzip the archive I downloaded to get 1 and only 1 file - Bits on Wheels.app - and when I go to open it, something flashes in the dock and then nothing. It too is "Read and Write".
Again, sorry for my ignorance, but I've literally been using Macs for about 24 hours, and I've been combing through forums all day with no luck.
