Hi all. I have a Mac Mini that was refreshed in late 2007. It has 3GB RAM (expandable to 4) and OSX 10.4.11. I believe the OS is 32bit and as such every website claims that it can only address 3GB of ram (which makes sense). The CPU is a Intel Core 2 Duo which is a 64bit chip. Now, I have Snow Leopard 10.6.3 unopened and was wondering if there is any point in upgrading the Mini based on my criteria below. 1)Is 10.6.3 64bit? 2)Will 10.6.3 allow me to take advantage of 4GB if I added RAM? 3)It is possible for me to upgrade ONLY the OS and not the iLife apps?...we absolutely love the current iPhoto version and don't want it mucked up. 4)I am contemplating replacing the hard drive with an SSD. However, I don't see any documentation on what OSX level actually supports SSDs. Will 10.4.11? Will 10.6.3? Thanks so much in advance!
