I have an old Mac Pro with the following serial number G87391T6UPZ. Can I upgrade this computer to 10.9 or 10.10?
I can't seem to find an official website that tells me 'yes' or 'no'. It runs on a 2.66 Ghz Quad-Core Intel Xeon. There was a website that mentioned early 2008 and up can upgrade. But not sure when this was made...
It says it is MacPro 1,1
