iMac Tuning: Memory and SSD Storage Upgrade or Replacement
All iMacs – not the 21.5″ Retinas though – can be upgraded with more RAM easily, which is fast and effective tuning for your machine. If you are brave enough, replace your old mechanical hard drive with a speedy SSD. This takes years off your Mac.
If you do not want to open your iMac and mess with the internals here is a top tip: connect an external Thunderbolt SSD to your Mac and make it your boot drive. Believe us, this is something you should have done years ago.
