Apple OS X Mountain Lion is a simple and intuitive operating system. Apple continues to update their OS in ways that just make sense -- to make the user experience both more efficient and more enjoyable. This update meets that description perfectly. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? There is little to not like about Apple OS X Mountain Lion. It works well. I suppose if there was one thing to complain about, it would be that there are still a number of popular software packages, particularly in the engineering space, that don't work with (or don't work as well with) the OS X operating system. This is no fault of Apple however. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? Apple OS X is solving the problem of having a human interact with a machine, both of which have very different way of thinking.

Senior Quality Engineer Enterprise (\> 1000 emp.) 5/5/2023 "Great OS to start your OS journey" 5/5 What do you like best about Apple OS X Mountain Lion? I personally like everything related Apple OS X Mountain Lion, as a beginner OS user. I started using Macbook in the year ~2018, and this is the first OS I used; I was amazed after using this OS in the first few days only, and I got hands-on of same very quickly. Believe me, I started preferring OSx as compared to Windows OS(no offence, please). Now I have only OS Macbooks at home. The best thing that I like about same is the SMOOTH UI experience like a fluid and airplay mirroring. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? I have very few things to share about what I dislike about Apple OS X Mountain Lion, but I observed that it required at least 8GB of ram to run Mountain Lion OS smoothly, which was quite expensive at that time for me. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? Allowing users to run all applications smoothly like one doesn't have to click each time to choose the selected window, three find swipe, and gestures, all help in saving multiple clicks and smooth navigation from one window to the user. Also, airplay helps in quick integration with other apps and transfer and receiving of files with a lightening speed. That is really great. It is benefitting me to save my time, do quick navigations and make me more productive by allowing me to open multiple apps at a single time Review collected by and hosted on G2.com.

ME Miguel Antonio E. IT Technical Support Small-Business (50 or fewer emp.) 1/23/2023 "A Look Back: A Review of Apple OS X Mountain Lion" 2.5/5 What do you like best about Apple OS X Mountain Lion? One of the most helpful features of Apple OS X Mountain Lion is its integration with iCloud. This allows users to easily sync and access their documents, contacts, and other important information across multiple devices. Additionally, Mountain Lion also includes a feature called AirPlay Mirroring, which allows users to wirelessly stream the display of their Mac to an Apple TV, making it easy to share content with others. Another helpful feature is integrating social media services like Twitter and Facebook into the operating system, allowing users to easily share content and stay connected with friends and family. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? One downside of Apple OS X Mountain Lion is that Apple no longer supports it. This means it will no longer receive security updates or technical support, making it vulnerable to security risks. Additionally, newer software and apps may not be compatible with Mountain Lion, which can limit the operating system's functionality over time. Another downside is that some users may find the system requirements for Mountain Lion to be relatively high, making it difficult to run on older or less powerful Macs. This can also make it difficult for users to upgrade their existing Macs to run Mountain Lion. Additionally, some users may find the new interface changes and features in Mountain Lion confusing or unnecessary, making it more challenging to use the operating system. It's also worth noting that OS X Mountain Lion was released in 2012, which means it is not as recent as the latest version of macOS and does not contain all the features and improvements that have been made. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? One benefit I would have is the integration with iCloud, which allows for easy syncing and access to my essential files and information across multiple devices. This can be particularly useful because I use various Macs and need my knowledge on the go. Another benefit I would have is the inclusion of AirPlay Mirroring, which allows for easy sharing of content with others by wirelessly streaming the display of a Mac to an Apple TV.
