Q: iMac extremely slow
My late-2012, 27" iMac is very slow. It's running macOS Sierra through an external, thunderbolt SSD drive. It was slow before but since installing the new OS, performance is terrible. For those of you who might argue that having an external SSD as the main computer drive is probably causing the problem, keep in mind that the computer was running perfectly fine for at least a year like this.
Below I have attached two screenshots with my iMac's specs. I also ran EtreCheck and I'm attaching the report below.
I would be really grateful if you could help me solve the problem. My mid-2009 MacBook Pro (2,66GHz Intel Core 2 Duo, 8GB RAM, internal SSD) is much much faster than my iMac which doesn't make sense to me.
