Update OS for iMac 20-inch, early 2008
Hi All,
I own an iMac (20-inch, early 2008), running OS X El Capitan (version 10.11.6).
Processor is Core 2 Duo - 6GB SDRAM
Can I upgrade to High Sierra or even Catalina? If not possible thru Apple, are there third party applications that would allow me to?
I know I could upgrade to a new model but I love this iMac.
Thanks in advance.
Christine
