"Everything You Would Expect from Apple"
5/5
What do you like best about Apple OS X Mountain Lion?

I love the easy navigation and usability of the software. I have been an apple user for over 20 years and have watched their software become more and more refined. Apple OS X Mountain Lion is everything that I expect from Apple software. It seamlessly connects to all of my other apple devices. I've also had very good experience with contacting their customer support when I had questions. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

The only thing I disliked is that it made my laptop run a little slower. I have an old macbook pro and it isn't quite powerful enough to run the software at its fullest potential. Review collected by and hosted on G2.com.

"Mountain Lion IOS Version Outdated But Revolutionary"
3.5/5
What do you like best about Apple OS X Mountain Lion?

Quick Tweets is a nice ease of life, you can communicate to all of your followers without having the distraction of going on just to tweet. The voice feature is pretty great, although I prefer typing over talking at times it is helpful. The Safari was a game-changer. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

I've always disliked having to pay for new version downloads, I felt like it should have come included with the purchase of the device. Mountain lion was more affordable than any other version before but you still had to pay. Review collected by and hosted on G2.com.

"Go more modern for better features and stability"
4.5/5
What do you like best about Apple OS X Mountain Lion?

To me there is nothing better than MacOS. The usability, organization, reliability, look and feel are unparalleled. Mountain Lion is an older version of the OS, and it's great for older machines if you need it. But Mac is on OS 11 now, and I recommend using an OS that is at most 2-3 years old if you don't want to run the absolute latest and greatest. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

I had no specific, major problems with Mountain Lion. I install an OS after it's been out for at least one year. And this version was no exception. But now, you would want a more updated version, especially for the security benefits and the feature sets, including compatibility with iOS. Review collected by and hosted on G2.com.

5/5
What do you like best about Apple OS X Mountain Lion?

1. Mountain Lion's excellent interaction with the Apple ecosystem is one of its strongest points. iCloud seamlessly syncs your data across devices, making your digital life easier.

2. With Gatekeeper, you can pick the level of program installation freedom you want, making your Mac safer than ever. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

Unfortunately, Mountain Lion is not compatible with all classic Macs. If your machine does not satisfy the criteria, be prepared to upgrade. Mountain Lion can also be a battery hog on older MacBook models, in my experience. Keep your charger close at hand. Review collected by and hosted on G2.com.

"Increasing Productivity: An Extensive Analysis of OS X Mountain Lion"
4.5/5
What do you like best about Apple OS X Mountain Lion?

From my experience, the iCloud integration in OS X Mountain Lion made sure that my data synchronised with all of my Apple devices with ease. Notification Centre helped me stay organised without being overly disruptive, while Messages for Mac made communication easier. My demands for effective and safe online activities were fully met by Safari's unified surfing experience and improved security features. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

In my experience, OS X Mountain Lion caused slowdowns in performance when it came to earlier Mac models due to compatibility difficulties. A few programmes were not optimised, which resulted in random crashes. Although Gatekeeper improved security, installing software felt constrained by it. These elements occasionally affected my overall user experience. Review collected by and hosted on G2.com.

"Apple OS X Mountain"
4.5/5
What do you like best about Apple OS X Mountain Lion?

The Apple's OS X Mountain Lion gave Mac users access to a number of noteworthy features.

What do you dislike about Apple OS X Mountain Lion?

Comparing Apple's OS X Mountain Lion to more recent macOS versions, it had a number of drawbacks. It had less sophisticated security than later macOS releases and lacked Continuity features for seamless connection with iOS devices. Older gear became incompatible with newer macOS versions, and finding software that worked with them became difficult. Siri, Apple Music, and Dark Mode are examples of features that weren't present in Mountain Lion but were added in later releases. Additionally, it possessed an outdated version of Safari, only moderate GPU acceleration, and several out-of-date services like Game Center. Although Mountain Lion introduced considerable upgrades upon its release, it gradually became constrained in comparison to the developing macOS ecosystem. Review collected by and hosted on G2.com.

"Mountain Lion - Great Platform"
5/5
What do you like best about Apple OS X Mountain Lion?

In Mountain Lion, Sharing takes on a deeply personal touch, becoming an intuitive system-wide companion. Picture the Share button as your loyal friend, always by your side in the Finder, Safari, QuickTime, Quick Look, and soon, even in your favorite third-party apps once they catch up to the trend.

This Share button, which feels like it's everywhere (just look at it gracing Safari's toolbar), becomes your magical portal to effortlessly share the wonders of the web. Want to hold onto that captivating link you stumbled upon? Just reach for the Share button in Safari. Need to send an important document to a colleague? Your trusty Share button in Finder lets you whisk it away via email, Messages, or AirDrop. Sharing files with someone? With the Share button in your corner, it's a breeze.

But what about connecting your own devices, making them harmonize seamlessly? This is where iCloud enters your personal narrative.

One of Mountain Lion's most remarkable strides is its profound integration with iCloud, a suite of services that magically synchronizes your data across every device you own. iCloud takes the burden off your shoulders and ensures that your data is effortlessly organized across your various companions: your Mac at the office, your iPad at home, and your iPhone in your pocket. Thanks to iCloud, living with multiple devices becomes a symphony of seamless information sharing, always keeping you in sync with the latest updates. Review collected by and hosted on G2.com.

What do you dislike about Apple OS X Mountain Lion?

Many Macs that had the potential for support were left behind, leaving users with limited options. Some resourceful individuals have developed third-party solutions, with varying degrees of success, to cater to these overlooked Macs. Interestingly, these Macs find complete support when running Windows 8, courtesy of Microsoft.

When it comes to AirPlay Mirroring, it's important to note that only a select group of Macs that align with Mountain Lion's requirements can enjoy this feature. Nevertheless, there are third-party applications on the market that can replicate or mimic these capabilities on older hardware.

Power Nap, a convenient feature, unfortunately, extends its embrace to only a small number of Macs compatible with Mountain Lion.

Upon its initial release, the "Save As" function left much to be desired, causing frustration among users. Fortunately, this was addressed and rectified with the 10.8.2 update, much to the relief of many.

Similar to the Lion update, various changes in gestures, scroll direction, window resizing, and other interface tweaks have the potential to irk long-time Mac users. These alterations have elicited strong reactions, leading to the availability of third-party "fixes" aimed at restoring the previous user experience. Review collected by and hosted on G2.com.
