"Fast, User-Friendly Apple OS"

5/5

What do you like best about Apple OS X Mountain Lion?

I used OS every day on my last work computer and loved how easy it was to sync content among my various Apple devices. You can use Notes and iMessages on your laptop, and whatever you add to these apps will also show up on your iPhone, for example. I liked using the Reminders feature for my to-do list (which I still use on my new laptop), which is great for staying organized. It's also a fairly fast OS; I've never had any issues with speed.

What do you dislike about Apple OS X Mountain Lion?

Airplay Mirroring is a great concept -- it allows you to display your screen on an HDTV with an Apple TV attached -- but I don't have an Apple TV and when I tried it on a friend's, I did not find it super intuitive to set up. If you do a lot of presentations and want to use this feature, that could be an issue, but there are so many other ways to share your screen that this was never an issue for my colleagues or me (we mostly use Google Hangouts now to do presentations, for example).

"Simple, intuitive, functional"

5/5

What do you like best about Apple OS X Mountain Lion?

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.

"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.

"Apple OS X Mountain Lion Review"

3.5/5

What do you like best about Apple OS X Mountain Lion?

I used it with my old apple device. It was really good for its time. Other operating systems should learn UX and UI from apple. It is feels natural and more reliable. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

Layout was good but, the icons are too old for 2023. I would prefer the newest version of Apple OS like Ventura or Monterey. Review collected by and hosted on G2.com.

"IOS update provides great new features"

3.5/5

What do you like best about Apple OS X Mountain Lion?

It's more user-friendly with a better UX interface and an interactive notification center, and you can see updates in your apps across all of your iOS devices. iCloud is more integrated and better formatted for document storage. Reminders in the Notes app are helpful. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

iCloud is not as intuitive as say, Google Drive, for example. Documents created in the Cloud are only accessible via supporting apps and are not universal, adding a little bit of inconvenience. Review collected by and hosted on G2.com.

"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.

"Solid OS"

4.5/5

What do you like best about Apple OS X Mountain Lion?

It has an intuitive interface. It is stable and has a great number of apps available in the App Store. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

You are forced to use a Mac computer/hardware to use this OS, yes I know there's potential for virtualization, but for support you need to use it on Apple hardware. Review collected by and hosted on G2.com.
