This Apple OS is quick. New apps and windows open in milliseconds, and apps rarely crash, but when they do, the Force Quit option clears up almost all issues. I rarely find myself having to restart the OS to ensure app stability and efficiency. I really like that you can have multiple "desktops" open with different apps and windows. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? I would like more options for multitasking and rearranging windows among one desktop. I would also like built-in FaceTime and iMessage capability so that I can seamlessly move from iPhone to Mac. Some apps (mostly games) will not run natively on Apple OS. Review collected by and hosted on G2.com. Recommendations to others considering Apple OS X Mountain Lion: This is a great OS, but you may want to start looking into the latest macOS for the best support from Apple. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? Windows simply was not doing it for me anymore. As a designer and heavy Adobe programs user, I got sick and tired of constantly restarting apps and the PC just to get my workday started. Apple OS X Mountain Lion runs many apps at once and does so with relative ease. Review collected by and hosted on G2.com.

Easy to use, not buggy, a significant improvement over previous updates, increased functionality over the last update Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? Many people say battery life has improved, but for me, my battery life has gotten worse. Review collected by and hosted on G2.com. Recommendations to others considering Apple OS X Mountain Lion: You can't go wrong with it. It's works smoothly, and the hotkeys make it conveniently one of the best programs out there today. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? Safari has improved, which makes browsing the web easy and more secure.

Customer Experience and Marketing Manager Mid-Market (51-1000 emp.) 5/1/2021 "Good operating system, but far outdated" 3/5 What do you like best about Apple OS X Mountain Lion? I found that this system was very stable and clean. Also, it came with a suite of creative products that I found were really really fun and useful. I used I movie a number of times for presentations, and started making music with Garageband. Also, one feature of Apple hardware is that generally when using USB equipment, there is no need to install a driver, which makes setup for external equipment very easy and stress free. This was especially good while working with end users at the IT help desk. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? It's very outdated in the year 2021. At this point, there are far, far more recent operating systems that can run on the same equipment. One of the things that I didn't like it about the time (and is likely still true) is that it couldn't run much of the Windows proprietary software that I wanted to use, and additionally only ran on more expensive (apple) hardware, rather than on the more cost effective windows machines that I found were available. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? I used it for all the basics, including web browsing, presentation creation, document/spreadsheet editing and creation, etc. While I was using it the system was much more timely, and I found that it filled all the needs that I had. If I remember correctly, you could even play the original starwars movie in the command line, which was a cool feature. Review collected by and hosted on G2.com.

Content Moderator Enterprise (\> 1000 emp.) 4/30/2021 "Snappy, great work OS, intuitive controls, offers many solutions for everyday utility" 5/5 What do you like best about Apple OS X Mountain Lion? I like the ease of use for the user. It makes it very simple to navigate and manage all the programs and files on the computer. Everything is snappy and reaction time is near instant in most cases. Not very related to the software itself but I do enjoy that it is based on a cat. I also enjoy how quickly my peripheals connect. I simply have to take out my wireless headphones and by the time I put them in my ear, they are paired and ready to go. I love that it offers so many features for everyday utility. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? I dislike how the font has changed and things have become rounded at the edges, this is just aesthetic/personal preference for the most part though. I do find it difficult to navigate the landscape of the OS when things move or steps are taken away/added to how things were done before. It doesn't make sense to me that there is not some kind of tutorial or walkthrough after an OS update to guide users through and make sure they have a pleasant experience. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? I'm able to manage multiple apps simultaneously without straing the OS, this is especiallly utilized for video conferences where it can become task heavy. Other than the ability to multi-task well I also find myself utilizing some of the built in shortcuts on the OS. Such as the pinch zoom, scrolling using 2 fingers, and definitely am using the CMD+(other shortcuts) more than a few times dailly. Review collected by and hosted on G2.com.

Mountain Lion definitely loads all programs very quickly, operates at a faster speed, and enables me to nimbly move across my laptop with multiple apps, windows, and tabs all open and running synonymously. It has my older device running like new! I was wary about making the purchase given the price, but I feel my return on investment has been ten-fold! Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? Mountain Lion took a very long time to download but I will say it was worth the wait! It could have also been my device so I'm not sure I'd entirely blame the software update for this. Review collected by and hosted on G2.com. Recommendations to others considering Apple OS X Mountain Lion: I would say it is definitely worth upgrading your computer and/or devices to OS X Mountain Lion. While typically I haven't sprung for updates - this one is worth it and the cost is entirely justified! Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? - Working on just a laptop without a monitor for 5 weeks - Leveraging multiple windows on browser with multiple (10+) tabs per window - Keeping a VPN and multiple applications running at once - Working across an ops/product heavy org Review collected by and hosted on G2.com.

AL AHolland L. Research Technician/Lab Manager Small-Business (50 or fewer emp.) 4/1/2021 "I miss mountain lion!" 5/5 What do you like best about Apple OS X Mountain Lion? I loved mountain lion. It was an excellent software that didn't have too many frills and lovely things to make the computer slow and complicated. Still, I could also use it for more complex coding projects, such as analyzing data from a CRISPR screen that our lab had conducted. I think the interface is just beautiful and well-organized. I will always be a Mac person! Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? The only aspect of Mountain Lion that is sub-par is the web browser, Safari. I don't use the safari because it isn't very functional compared to other browser options such as Mozilla Firefox and Chrome. Maybe if I spent a bit more time on it, I wouldn't be as annoyed with it when it doesn't do what I want it to, but I gave up on it a long time ago. Review collected by and hosted on G2.com. Recommendations to others considering Apple OS X Mountain Lion: I love it! Don't upgrade to Big Sur, and I have had so many issues with it! I don't know why I updated my software from mountain lion because that was the best, most up-to-date software that still ran well. I think the new software is too new for my 2015 computer, which is rather frustrating as it is only six years old! However, this is an apple problem and not the software. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? I use it to do everything on my computer! I am constantly using many types of software, and I need to keep everything very organized, so I don't get my projects mixed up or lose anything. I also need my programs to run smoothly because if they don't, then I can't do my job! Review collected by and hosted on G2.com.
