I have a late 2013 27" iMac. It has 8 GB RAM & 1 TB fusion drive.
I don’t use it for much processor intensive work. I do bulk OCR’ing of scanned documents, a small amount of image editing and no video editing. Most of my other activities are typical: spreadsheet & document production, research and filing using DEVONthink, storage & enjoyment of photos and music. I don’t use it to serve or watch movies. The 2013 iMac works great except too frequent (several times a day for 20-30 secs at a time) freezing of the OS and display of the spinning beach ball. I recently tried a ‘nuke & pave’ but this made only a small difference to the spinning beach ball. When not frozen, iMac does everything I needed it to do and speed isn’t really an issue.
Aside from missing out on enjoying the fabulous retina screen, I am wondering if upgrading the RAM in the 2013 machine would get rid of the spinning beach ball? If so I am thinking of sticking with this old machine and awaiting Apple’s big iMac redesign in 2020/202.
Would I be right in thinking that a RAM upgrade would most likely resolve this? If so any recommendations as to how much RAM (16 or 32 GB) I should buy, and what brand/model etc.
