iMac RAM

My iMAC has 8GB of RAM and is extremely slow. How can I make it faster? It's not that old and I have almost all storage available.

iMac 21.5″, macOS 10.15

I understand your iMac is slow. Please determine if the same problems occur in "Safe Mode": How to use safe mode on your Mac.

There are many different iMac models and not all of them have user-upgradable RAM. Fortunately it's very easy to determine if your Mac's performance is being limited by available memory. Please read Check if your Mac needs more RAM in Activity Monitor. If the "Memory Pressure" graph is frequently "red" your Mac will benefit from additional memory. If not, it won't. It's that simple.
