Very very slow 2017 21" iMac using less than 256MB of it's 1 TB,
Is this just normal after 7 years? I mean, 10-12 seconds between actions. I know tech speeds increase about 2x per year. Are there any solutions? Maybe get an SSD start-up drive or just renew the iMac? It's not Apple silicon. And I guess if my friend wanted Apple Vision, ???? It wouldn't work with it! Thanks R
