Where is CD slot on iMac?

On most iMac models, the CD/DVD drive is located on the right side of the computer, towards the back. You can insert discs into the slot that is integrated into the iMac's casing. However, it's important to note that newer iMac models, starting from 2012, do not include an optical drive, as Apple has shifted towards digital media consumption. If you're using a newer iMac, you would need an external optical drive to read CDs or DVDs.
