I have a very old MacBook Pro running Mac OS 10.4.11. I want to upgrade the OS but not sure what is recommended. I mainly use the Mac for internet and photos. Processor 2.16 GHz Intel Core 2 Duo, Memory 1 GB 667 MHz RAM
This system can run the last version of OS X 10.7 "Lion" if upgraded to at least 2 GB of RAM. However, although it has a 64-bit processor, it has a 32-bit EFI and is not capable of booting into 64-bit mode. It does not support "OpenCL" either.
