Hi All,

I’m working on updating a 15inch MacBook Pro (October 2006). I’m currently running 10.4.11 but trying to update to 10.5 so I can get to 10.7.5. I was unable to use the 10.5.1 download from the Apple Store, saying that I need 10.5 to install. If I buy a used 10.5.1 retail disc will I be able to install it on my 10.4.11 operating system? Or do I need to find a 10.5 disc? Thanks for the help!
 
The only option for you is the 10.6 retail disc that is still sold by Apple. Once that is installed you will be able to upgrade to 10.7
