iMac 2007 OS upgrade
I'm not that familiar with iMac products. I just had the iMac (20 inch, mid2007) with OS X El Capitan 10.11.6 placed in my office. I have A LOT of PC files from Microsoft Office software. I wanted to install the iWorks essentials apps but cannot because it say's my OS isn't new enough. I have 2 Ghz core 2 Duo 4 GB 667 Mhz DDR2 SDRAM. Am I able to upgrade further or get any apps or programs that will help me with MS Office compatibility?
