What components are upgradeable on my iMac Intel EMC 2389 that would be worth the time and cost?
You currently have the middle level machine, the RAM is maxed out ar 16GB Apple iMac “Core i3” 3.2 21.5-Inch (Mid-2010) Specs Identifiers: Mid-2010 - MC509LL/A - iMac11,2 - A1311 - 2389 Maximum MacOS:X 10.13.x* https://everymac.com/systems/apple/imac/… Taking it to the “Core i5” 3.6 will only give you a 15% increase in benchmark. Your best best will be going to an SSD drive. You have a Serial ATA (3 Gb/s) bus so you will need a drive that is backward compatible. You will also need the OWC thermal sensor to prevent run away fan issues. Here are your options: https://eshop.macsales.com/upgrades/imac…
