Hi, first I want to introduce myself. My name is Tigran. I have been doing professional photography for 10 years. So I'm always using Photoshop and Lightroom. But 2 years ago I decided to go to college again and become a software engineer. I know, it is a weird mix: programmer-photographer. So now on my computer, I added several new applications like IntelliJ Idea for Java, xCode for Swift and Clion for C++... I'm writing all these so you can understand that at least 10 years I'm doing heavy lifting staff on my computers and I know when computer works slow. A several months ago I bought a MacBook Pro 2.3 GHz Intel Core i5 8 GB Ram, the basic model and I'm so happy with it. It is working perfectly.
Two days ago I bought from BestBuy iMac Retina 4K Display 3.0GHz Intel Core i5 8 GB Ram and when I turned it on, installed all the updates, tried to install my apps, I understood that something is wrong with it. It was so slow. It was extremely slow. I did all the tests to run HDD, check its speed, the checked the processor speed, everything was fine. But I decided to exchange it, because when I was trying to use Photoshop or xCode it was taking like 2-3 minutes to just load the program. I went to BestBuy and described the situation to the computer person, he turned the iMac on and immediately says that yeah, it is definitely very slow. We spent 30 minutes to test it and he suggests me to exchange it, to get another one, because definitely, something was wrong with the one I bought.
So I got another one. Exactly the same thing: very slow, taking a while to load simple files, to open simple programmes... I returned it. So the problem I assume is with the hard drive. In 2018 when even basic $300 dollars computers come with SSD but $1400 mac with 4k display doesn't have that. I'm suggesting everybody who will read this not to buy iMacs without SSD. Please don't waste your time on returning items.
