I have just purchased a new iMac with 8 Gb of unified memory (larger capacity machines are virtually impossible to get at the minute) I wanted a higher capacity machine so I would like to increase the unified memory if possible. I would imagine that I could use an external SSD drive if I need extra storage in the future but I would really like to increase the unified memory. Thank you in anticipation.
Have a look at this support article but with newer model iMacs I suspect you cannot change the memory after purchase. Install memory in an iMac - Apple Support

Current iMac 24-inch models have the CPU. RAM, Storage, and GPU on one chip. RAM cannot be added after the logic board starts down the assembly line. No one, not even Apple, can give you more RAM that what you have now.
Thank you very much for your response. I had a sneaking suspicion that this might be the case. Thanks once again, I really appreciate you taking the time to reply.
You're welcome.
The RAM is upgradable only at time of purchase. It's "soldered-in" as an integral part of the computer and is not meant to be changed in any way by the user.
