I have a 2009 13-inch Macbook running OS X Lion. I also have 2 GB of memory and at least 8 GB of available space but the App Store still won't let me install OS X Mavericks, saying it "cannot be installed to this computer" with no other explanation. This is really annoying as every time I try to run Final Cut Pro X it crashes as my OS isn't advanced enough for it so I really need to upgrade to Mavericks, please help!
MacBook, Mac OS X (10.7.5)
Although the error message is different, try the steps in this support article:
OS X Lion: Installer reports "This disk cannot be used to start up your computer"
Other documentation says that you need at least 9 GB of available space on the startup volume. Also, with only 2 GB of memory, you probably won't get full performance from Mavericks if you do manage to install it.
Try checking the model number.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
