      Sleek design, unfortunately too slow for my taste

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      I am an avid Mac user-have been for 12 years now-between mac books, iPads, iPhones, Apple TV, and even time capsule-I prefer Mac over any other brand for simplicity sake. My primary use for this 21.5” iMac is photo editing and web use. I found this 3.0 GHz processor thinking for too long of periods at a time between applications. The 4K screen has crystal clear resolution to my eye’s desire. I did, however, feel the screen was a bit small even with having a small writers desk. This 21.5” has a nice price point at just over $1k, but all in all, I wasn’t 100% satisfied with my purchase and decided to exchange it for the 27” 3.4GHz-which the extra .4GHz does the trick for my liking! Best Buy gave me some difficulty with the purchasing process (I price matched-but customer service rep didn’t do it correctly and I had to go back to the store several times...additionally, I purchased Microsoft Office personal to go with the iMac-which I found out they failed to activate upon purchase when I got home-so that was another trip back to Best Buy). I would still buy electronics through Best Buy again just for their decent price matching policy..but as for software, I will be going elsewhere in the future! Overall a great basic computer if you are looking to transition into using Apple products-but still would suggest paying the extra $500 or so to upgrade to the 27”-it’s worth it!

      Super slow computer for $1400 without SSD

      • My Best Buy® MemberMember

      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.

      Disappointingly slow

      • Verified PurchaserVerified Purchase

      I have been using this new computer for six weeks now and it is disappointingly slow. With the Intel Core i5 3.0 GHz processor (with turbo boost up to 3.5 GHz) and a discreet Radeon Pro graphics card, I expected a speedy computer. It is not. Documents are slow to open; there is frequently a lag time in completing tasks as simple as adjusting the volume; and Spotlight searches can take 3 – 4 time longer than on my old, 2008 iMac. Another disappointment is Apple’s decision to eliminate the built-in DVD drive and remote control that used to ship with iMacs. (Admittedly, these are changes that Apple made a few years back but since they did not affect me until the purchase of this new computer, I will mention them here.) I watch a lot of DVD’s on my computer and liked the convenience of a built-in DVD drive. Now, not only do I need to spend extra money for an external DVD drive ($79.99 for an AppleSuper drive) and remote ($34.99 for a Bluetooth media remote), but my desk has an additional peripheral cluttering it. There are no USB ports that are easily accessible from the front. Gone is the USB ports that used to be integrated into the keyboard. They are all inconveniently located in the back now. To get around this, I have had to purchase a USB hub, which is yet another peripheral cluttering my desk for an item that used to be part of the computer. I miss the numeric keypad on the keyboard. To purchase a separate, third party keypad runs about $50. This is another item that used to be included as part of an iMac purchase and now costs extra. Also, the up/down arrow keys are annoyingly small and therefore hard to use without looking at them. One feature I do like is the Retina screen. It is beautiful! When I purchased the computer, I was expecting the biggest benefit in using a Retina screen would be in the rendering of images and graphics. Yes, they are clear and look amazing. But the biggest (and unexpected) benefit of the Retina screen is the resolution it offers type. Text displays with a sharpness and crispness that rivals a printed page. While the Retina screen is nice, it does not offset the frustration of having new computer that is slow. Good chance that my next computer will be a PC AIO.

      Was a Windows/MS user now OS X/Mac

      • My Best Buy® MemberMember

      First off, I've found both delight and annoyances with Windows and OS X in general. There are features in one I hate and love in the other, and vice versa. I use VirtualBox to run Windows within my Mac. So now getting that out of the way. Second, I am comparing this new edition iMac to my 2015 Macbook Pro Retina 13" model. Obviously, the 21" inch is larger but overall both screens are great to look at. Great viewing angles, images are clear and bright. Didn't see any lag, artifacts, pixellation, etc even when running a movie file from an old USB 2.0 external drive. Now the Cons: 1. SSD (on Macbook Pro) vs Standard "spinning platters" drive; there is definitely a lag in boot up. Whereas my older MBP boots pretty fast <5s, the iMac does take about 10-15 sec to boot up from a "cold start". 2. When running VirtualBox with Windows as the guest edition, I had issues playing the same video file where it lagged, stuttered and pixelation when trying to play in full screen mode. I have no issues when doing the same thing on my older MBP. My guess is that because the iMac does not have SSD drive, that my be the issue. 3. Sometimes when opening up programs it seems it takes a few seconds longer than my MBP. All these minor issues may be related more to this particular iMac using the standard SATA hard drive, rather than using SSD or the Fusion drive (combo SSD and "platter drive") but I can't be sure except with my unscientific opinion. However, when encoding a video to MP4, it was faster on the iMac compared to my older MBP with SSD. It's definitely a very capable computer and I have no regrets with the purchase. Apple should have just put Fusion drive in every new model, similar to what it did with SSDs on all Apple Laptops.

      Great Computer!

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      First, I just want to point out that I have always been a PC owner/user. This was my first macOS purchase (Though, I have used iPhone for awhile now). I originally bought the mid-2017 4k 21'' iMac and that worked great, but for the extra five hundred dollars the 27'' was a better bang for my buck, so I exchanged it. (5k vs 4k, 27in vs 21.5 in., better graphics card, expandable RAM, etc. ) First Impressions: First, the screen. Holy cow, it's beautiful... I am spoiled now and can't ever go back to anything else. Amazing. Absolutely amazing. Operations are very smooth. There are times when the computer will give me the beachball and freeze for 20 seconds, but that doesn't happen often. Very easy to customize properties and getting used to the macOS just took a few days. While what you get is a good deal for an apple product (2 things are certain, death and the apple tax) a PC at an equivalent price point would smoke the iMac as far as performance goes. Yes, I'm looking at you AMD Pro 5XX vs a GTX10XX. Last thing, the screen for this All-in-one looks dated because of the large black bezels. It's time for apple to start doing what it did to the iPhone with the iPhone X. Get rid of the bezels and you'll have one sexy computer. Bought @ Cedar Hills Crossing Best Buy: The people that helped me do my return and buy my new iMac were amazing! Thank you again for everything!

      Very Disappointed with 27" iMac keyboard

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      Actually, I have a 27" iMac. Originally, the salesman sold me the 21.5 version by mistake and I had to exchange it. Also found out later, that I could have ordered a Mac with the extended keyboard instead of buying a separate number pad. I purchased the Mac after stupidly updating my HP laptop to Windows 10. I wanted something that would work without waiting. What a mistake! The BT keyboard and mouse stop connecting to the Mac after a period of inactivity. Sometimes I can get it to reconnect by shutting off the keyboard and turning it on. Sometimes I have to reboot. I just leave the keyboard plugged in all the time. Otherwise I cannot type. When the "magic" mouse quits, the computer is useless. I am thinking about buying a corded mouse just for troubleshooting. I tried debugging the Bluetooth by resetting the Bluetooth and by factory reset of all connected BT devices. My son spent an hour with Apple tech support. They did not fix it and sent us to Best Buy for a new keyboard. BB said to go back to Apple and file claim under warranty. I wish I had my $1,900 back!!!!!! This is my very first 1 star review. Never thought it would be on an Apple product.

      Great experience for 1st time Mac user!


      Being the first to write a review on a product that just released is not only exciting but a little nerve wrecking. I'm not sure how much my review will compare to pro Mac users, but I'll do my best. I decided to purchase my very first Mac as I've been transitioning from Android to Apple and decided I needed to make the switch from PC to Mac to finish my collection. I was excited knowing that not only was I finally able to purchase the beautiful Retina 4K iMac, but that I was purchasing a brand new one that was released this month! Being completely new to Mac, set up from out of the box was very easy to follow and within minutes I was able to explore what Mac had to offered. Just to list a few. The display is so beautiful and clear and I love how I'm able to sync with all of my apple devices. I can also text from the Mac and finish the conversation elsewhere. Of course that is just a few of what this Mac offers. Goodbye PC, Hello Mac!!!!

      Great Except....

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      The iMac is great, but there are 2 items of contention, 1) The included keyboard sux, period. I have no real comment about the mouse, as I don't like it, but that is me. 2) The print screen defaults to 2 sided copies and there is no way to change it in the documentation. It took two hours with Apple Support to fix a simple problem they weren't aware of - simply change the setting in the print screen to uncheck two sided, print a document, close the document, the reopen and set the print screen from default to last used and reprint the document, That will keep the one sided copies defaulted until you change the setup again. If you do, repeat the process. Sounds simple,, but it took 3rd level support to figure it out. The Support Community says to change the CUPS setting in the guts of the machine, don't! The other thing about Apple - their support is outstanding. Whenever I contact support, I suggest that they take their health break, 'cause "we're gonna be here awhile" - I don't have simple problems. They have stuck with me for hours until we resolve it - they totally own my problem to the solution.
