Does anyone know whether a MacBook Pro 2,2 will actually see 4GB RAM with Lion installed? My friend has a late 2006 MacBook Pro 2,2. It has 1GB RAM, and she would like to upgrade to Lion (min of 2GB). If possible, I'd like to put in a minimum of 4GB. But most of the resources online say the machine will only address 3GB. This appears to have been due to 32-bit limitations of the OS at the time (as the Intel chipset supports 4GB addressable), so unless there's specifically some hard-coded limitation, Lion should be able to properly address 4GB, right? Thanks in advance, and sorry if this has been answered elsewhere; I couldn't find it in any thread.
