      An Almost-Perfect Design

      • My Best Buy® MemberMember

      I bought this Best Buy and finally got all of my files, music, and movies downloaded and settings as I want them, and have had a chance to play around with it. I have two other Macs (a three year old Mac Air I use for travel and a Macbook Pro I bought at BB in early May that I love). I wanted something with a larger screen for the house that I could move relatively easily, but didn't want a traditional desktop, with all the cables and room that requires. This one fits the bill nicely. Mine is the 21" with the Retina display. The screen is absolutely gorgeous. The PC is very quiet, and there is no fan or hard drive noise that I can discern. I got this one after ruminating for several days whether to get the 21" or 27" (both were on sale at Best Buy), and this one fits my needs a bit better in terms of size and was a bit cheaper. If you spend a lot of time online and doing basic tasks, or you like to watch movies, this thing is wonderful. Wireless connection speed is excellent and it does have a traditional ethernet port, unlike the new Mac laptops, if you want a wired connection. It also has a standard SD card slot in the back and accepts standard-form SDXC cards, unlike my Macbook Pro, which required a proprietary card. Keyboard is very small, light and flimsy-looking but works well and, like the included Magic Mouse, is rechargeable via the included lightning to USB connector. A standard iPhone lightning cable will perform the same function. Only negative is the included 5400 rpm 1 TB hard drive. I knew this included that when I bought it, but couldn't justify the huge premium Apple charges to move up to a Fusion or especially Solid State drive, and those are difficult to find in retail stores, so you'll likely need to configure and order it on the Apple website, and then you'll pay full markup without a sale like the kind Best Buy routinely offers. Nonetheless, the base drive is painfully slow at times, and this iMac's boot up and general feel are noticeably much slower than either my MacBook Pro or Air, despite similar (or more, vs. the Air) memory and a much-superior processor. Memory is adequate at 8 GB and, in the 21" version, is not upgradable. The 27" version does still have user-accessible slots and you can add memory. The hard drive is not easily upgradable in either and not something I'd recommend anything other than an advanced apple user attempt, and would probably void your warranty. In mine though, I installed a memory management program and utilization seldom goes over 60%, so 8 GB should be fine for now. The form is beautiful and the display quality is flawless. Once again, excellent Apple execution EXCEPT I'm really disappointed that they made the decision to put such an archaic hard disk in an otherwise premium computer, and it's not designed to be able to upgrade. Online tasks and general usage are fine, however, once everything loads up. Overall, still a really nice machine and I would recommend, with the caveat that people are aware of the obsolete, slow hard drive that can really impact performance feel.

      We bought this for my wife . She has been using Windows for the past 20 + years . She was retiring and having to give up her company owned Windows Laptop. I suggested Apple because I switched from windows almost 10 years ago. I find I have less issues and lock ups with Apple . However my wife has been having to relearn some keyboard short cuts and misses the Office applications she had . So she is exploring the Apple programs to see if she can adapt . If not I told her they have Office for Mac that we could buy and install for her . I can help set up her new keyboard to react like a windows keyboard but I wish Apple had a box to check in System Preferences to make the Apple keyboard react like a windows keyboard would . Also Apple should include a CD/DVD read and write unit since it has eliminated it to have a thinner body . My wife wants to learn a language with Rosetta Stone so we had to buy a separate unit for her to be able to use the cds that come with it. Overall it is a great computer with a stunning display . We love to view our pictures and camera movies on the retina screen. If you've had Apple before you won't be disappointed . If your coming off Windows and using Apple for the first time , have patience and check online tutorials and you can make the transition with little to no problem .

      When I read other reviews saying this machine was slow, I told myself it wouldn't be THAT bad. Unfortunately this computer is indeed excruciatingly slow. I've never seen a pinwheel spin so much and for so long. It took 32 seconds just to boot up Microsoft Word! My five year old computer has it open in 6 seconds. I was hoping this would be great machine, but sadly it is one more product Apple has released recently that strongly states Apple no longer puts the users experience as their top priority. I called Apple tech support to ask what I could do to speed up my machine. The representative told me that it is a well known and documented issue and that there isn't anything I can do except return it and buy an upgraded model. In fact, the representative told me that when someone inquires about getting an iMac, they immediately let them know they need to pay the extra $100 for the fusion drive or look at a different computer. But there is a big problem with upgrading to the fusion which. Apple stripped down the fusion drive for the late 2015 models. It now only has 24gb of solid state hard drive on the 1tb fusion drive. If you want the fusion drives that come with 128gb of solid state hard drive, you need to spend eve more money for the 2tb version. This is extremely disappointing. Fingers crossed Apple gets back on their game sooner rather than later. As much as I don't want to make the switch, I'm considering returning this and *gulp* going with a Windows 10 computer. Even on a great sale, I would not call this computer a good deal.

      Very good machine, but it's not excellent.


      Generally this iMac is very good. Powerful processor (3.1GHz). Memory is ok(8GB) but it's onboard and you can not upgrade it later. I'm not happy with storage (1Tb Hard drive). It's big enough but, it's old generation of storage and when you open big file video or photos you can see that it's slow. I work with Go pro application (video) and I can see that that extremely slow. Display is very good. Retina 4K is amazing and it's not just for watching 4k video or photos. When you read an article on websites, it's like a print on a piece of paper. (readable with high contrast). sound is ok. (I have plan to buy speakers). Keyboard and mouse are wireless and chargeable. I wish the keyboard had LED lights at dark time. I had a Macbook before and for me it's hard to work with mouse. That's why I got a magic pad that it's an amazing stuff. I bought iMac on good sale, and it's worth it, but i'm not sure it worth for $1500! If you are a general user probably is ok for you ,but if you want to work with semi- pro applications it's good to upgrade at the first (you can order it just in apple website or apple store) with Fusion drive or Flash storage plus 16GB memory.

      I have had 2 Mac Minis over the last 8 years. I decided it was time to upgrade, and wanted to get rid of all of those cords all over my desk. Now the Mini's were excellent, and still work. My grandson loves the Mini (late 2009), which works great for what he needs or wants to do. My daughter was looking at the price of the Mac's a few weeks ago, and realized she couldn't afford one at this time. My Mac Mini (2014) will go to her. But I absolutely Love this IMac. It has the Retina screen, so the pictures are awesome. It is so easy to use, and fast. I like that the keyboard and the mouse are cordless, and plug in to the computer with a lightning cable to charge. No more charging batteries as in my former Apple keyboard and Apple Mighty Mouse. It has so much space on the hard drive, I won't come close to filling it up. It came with lots of great programs, although I did buy an antivirus program (Kaspersky Total Security) and Microsoft Office. When I bought it, It was on sale and a great deal. I hadn't actually planned to buy a new computer when I went into Best Buy, buy realized that I could make my daughter happy, and have my dream computer at a very good price. I've only been using it for a few weeks, I had some problem installing Microsoft Office, and the Microsoft person was unable to help me. I called Apple Support and she immediately discovered that I was in a start up disk, not the actual hard drive. She spent several minutes walking me through installing Office, and answered a few other questions I had. Support was wonderful!

      I have been wanting and waiting to be able to finally purchase my MAC - I'm talking almost 20 years. (sad face) I am a photographer and graphic designer (I really am though; I have the education, the overwhelming student loans, the full time job, all of it!) and was making do with my previous Toshiba Laptop. Don't get me wrong, that trusty little guy was great for surfing the web and a few minor projects, but hard-core photo editing sessions with Lightroom & Photoshop open, plus, yknow, basic operating system functions running in the background, would sloooooooowww evvverrrything doowwnnn... (in case you can't read sloth, that says "slow everything down"). The first time I opened a new session in lightroom on my new MAC it was like a giant weight lifted from my shoulders! It wouldn't take 20 minutes to edit one photo?! And the angels sang! Not to mention that I also had Pandora playing some kickin' tunes, Facebook open to answer client questions, and so on! Hallelujah.

      After about 25 years using a PC, I decided to switch after my last experience with a lemon of a laptop, and all the problems I had with Windows 10. This is my first Apple product, and I really like it. It's very user-friendly, and I love the big monitor. I love Safari, and the ability to combine my email accounts so that they all show up in one place. I'm not that impressed with "Pages," so I bought Office 2016 for Mac. There was a learning curve there, but not so much that I couldn't figure it out. At this point, I'm still having trouble being able to listen to my music I downloaded from my PC, but I'm sure Apple Support will be able to help me with that. The computer came with a keyboard and "magic mouse." While I like the mouse, I don't like the keyboard at all. If you have big hands, you'll probably like it fine, but if you have small hands, you'll probably have to buy another keyboard like I did. I got the Logitech illuminated keyboard for Mac, and it's much better for typing. Other than the keyboard, my only other complaint is that it's slower than my PC was, and that surprises me, especially for what this cost. However, I'll take slower in return for a computer working beautifully otherwise, and for great support. No more PC's for me!

      Beautiful simplicity

      • My Best Buy® MemberMember

      So easy to set up. LOVED getting rid of all the cords from my old PC. Can be a bit difficult to transfer files from an old PC without wifi. Beautiful display. I'm loving the interactivity with my iPhone and iPad. I'm not a techie. I use my desktop for basic stuff: surfing the web, watching videos, paying bills, filing taxes. Nothing fancy. I know this iMac can do so much more. But I have very little patience with poorly functioning computers so it saves my sanity and that makes me very happy. I'm also a neat freak who loves organization and the simplicity of it is fantastic. I was even impressed with the packaging. There were 4 things in the box! Truly. The only cord was a charging cord for the mouse and keyboard. It comes with a tiny accordion style booklet start up guide. So easy. I also treated myself to a new modem/router and wireless printer. Everything is working seamlessly. My only regret is not getting rid of my old PC sooner. It is a little more expensive but well worth it!
