You may not need a new iMac!
An SSD drive and more RAM and you’re good to go!
Maybe you’ve been struggling to open certain applications like Photos or iMovie or your older iMac is simply getting too painfully slow now…
While adding more RAM can help your iMac multitask better, quite often replacing the old mechanical hard drive by an SSD will make a huge difference.
A regular mechanical hard drive has a disk that looks like a small DVD that spins at high speeds and a reading head that reads and writes data for you. The very structure of it makes it slow and prone to defects.
An SSD is simply a collection of micro chips that don’t move at all.
This means your data is accessed pretty much instantly and the rate of failure is much lower than a regular drive.
