It's versatile, fast, and intuitive to use. Its excellent GUI is interactive and insightful of all the processes running on it, making life much easier. Compared to windows, it is easier to use. Review collected by and hosted on G2.com.
Apple products are very expensive and do not come with much free software. Paid applications are good but come with limited validity which makes them very expensive to use. Review collected by and hosted on G2.com.

For a lot of free or outdated MacOS programs, MacOS X Mountain Lion is the highest system that you can upgrade an iMac or MacBook to in order for the software to be compatible. A lot of users who use DJ software prefer to use Mountain Lion. Review collected by and hosted on G2.com.
The interface is old compared to the current MacOS versions. The graphics, icons and preinstalled software are all dated. Trying to locate backwards compatible software like Google or Firefox to download and install is virtually impossible. Review collected by and hosted on G2.com.
It made things run faster for me. The system felt that it was smoother and better RAM management. The Battery life had also improved for me. I got an extra 30 minutes to an hour when using my computer. The size it takes up on the hard drive was improved, too therefore saving space for my laptop. And of course, it being free update makes it great, more features without having to pay more. Review collected by and hosted on G2.com.
It was a big download for me, and it made no improvements to SSD use or drive platter speeds. Review collected by and hosted on G2.com.
Previously I used to work with Windows where a restart is must every 2-3 days, but with mac I have no more to worry about restarts anymore. Memory management is perfect. Ux, security, features, ease of use is just perfect. For a developer this OS is very nice to have. Review collected by and hosted on G2.com.
Nothing as of now, I am still exploring this wonderful OS. While moving from windows to mac os, it has some learning curve but yes that is expected when we move to new things. Review collected by and hosted on G2.com.

One of my favorite things about Apple OS X Mountain Lion is the dictation feature. As someone who works in healthcare and is required to create several notes every day, dictating my notes and having them immediately transcribed is a godsend. Review collected by and hosted on G2.com.
Sometimes when I have multiple applications and/or windows open, I do notice that my computer's functionality as a whole performs slower than usual. Is this concern directly attributed to Mountain Lion, or computer systems as a whole, I don't know, but it is something I do notice. Review collected by and hosted on G2.com.

I really like this operating system because it works very well on low-developed apple products with a low ram and still the device is still very fluid. Samsung, for example, has an operating system that is a little incomplete, so much so that when you are using a Samsung device, it starts to give some crashes and visible bugs Review collected by and hosted on G2.com.
I don't like a single thing about apple where its system is very restricted where some parts are good, like an apple product it's very rare to have or get some kind of virus, but on the downside it's too closed to do activities such as downloading apps from outside the app store, which is quite different from android that already lets you do this.

A dependable Mac Operating System from 2012 that introduced Malware blocking and iCloud services for backup and data sharing across both iOS and Mac OS. Apple also introduced Messages to replace iChat; this was a quantum leap for cross-device messaging. Review collected by and hosted on G2.com.
The OS, although great at the time (2012), is now very dated and does not have the applications or features that later versions of the OS include. There is also no support for 64-bit hardware in this Operating System, the standard hardware configuration for Apple devices. Review collected by and hosted on G2.com.

I like the fact that it is one of the oldest mac OS that can be easily downloaded and installed, and an empty MacBook machine after then, It is possible to be upgraded to the latest version mac OS. Review collected by and hosted on G2.com.
My dislike is that during the revealing of Mac OS X Lion, it supports fewer DMG files to run applications, and also it gives very little of Mac apps and no update available when using it. Review collected by and hosted on G2.com.

What I like the most about the Mountain Lion is its notification feature because when we drag two fingers, we will be able to see notifications. Review collected by and hosted on G2.com.
I wouldn't say I like the feature of not installing the latest software, like when I try to install some software like Adobe after effects for editing, but it's not work in the Mountain Lion because of the OS version. Review collected by and hosted on G2.com.
