iMac Speed Upgrade: Fixing a Slow, Lagging Mac with a High-Speed SSD

The iMac was abnormally sluggish, taking several minutes to boot up. Opening large programs often resulted in the constant spinning beach ball. Overall performance was laggy, caused by a failing and slow mechanical HDD (Hard Disk Drive).

Upgraded the primary storage to a new SSD, which directly solves the iMac's slowness. The result: booting up in seconds, launching apps instantly, and a smooth user experience—like getting a new computer at a fraction of the cost.
