Apple OS X Mountain Lion Reviews & Product Details

Apple’s OS X 10.8 Mountain Lion (released in 2012) stood out primarily for bridging the gap between the Mac and iOS ecosystems, while refining the rough edges of its predecessor, OS X Lion. The most notable highlights included: Arrival of iMessage (Messages app): It replaced iChat and brought native iMessage to the desktop, allowing seamless texting and file sharing with iPhone and iPad users directly from a keyboard. Notification Center: A centralized slide-out panel that brought organized alerts, banners, and quick toggles to the Mac for the first time. Deep iCloud Integration: Notes and Reminders finally became standalone apps synchronized across Apple devices in real-time, alongside features like iCloud Tabs in Safari. AirPlay Mirroring: Made presenting and media streaming effortless by allowing Macs to mirror their displays wirelessly to an Apple TV. Gatekeeper Security: Introduced a pragmatic layer of malware protection by vetting software signed with Apple Developer IDs while still letting power users run unsigned apps. Power Nap: Allowed sleeping Macs to sync iCloud, perform Time Machine backups, and download updates silently without waking the screen. Review collected by and hosted on G2.com.

Aggressive "iOS-ification": It continued the trend of importing mobile UI paradigms that felt unnecessary on a desktop, especially the skeuomorphic, textured designs—like the faux-leather look in Calendar and the yellow legal-pad styling in Notes. Notification Overload: The slide-out Notification Center was useful, but it also introduced a steady stream of banners and alerts to a platform that’s traditionally meant for focused work. Early on, the controls for silencing noisy apps felt limited, which made the interruptions harder to manage. Review collected by and hosted on G2.com.

Mountain Lion completely changed how Mac users communicated by replacing iChat with Messages. Review collected by and hosted on G2.com.

I don't have any problems with this software Review collected by and hosted on G2.com.

it old version, however, it was one of the first versions that worked with iPhone and Mac. Well, I remember using it and solving some problems I had in the past because start to work with my updates on both iPhone and Mac, others think that start pop up was the iMessage. I remember that was the first thing I used on this operating system. Review collected by and hosted on G2.com.

Well, it has improved with their time. At that time, because it was the first operating system working with AirPlay, or Apple TV, it was limited in the application features, and the graph was not very good. Review collected by and hosted on G2.com.

I WAS easy to use and stable, but it ended support in 2015. I still run it on some older 17" macbook pro that are from 2011/2012 since they were the last version with nvidia gpus which i sometime use for local ML development. But with no security updates in nearly a decade I cannot recommend it for general use. Review collected by and hosted on G2.com.

Like so many apple products they have a very limited lifetime before they force upgrades. But my hardware was not capable for the upgrades so I had to stay but lost security updates. Review collected by and hosted on G2.com.

What I like most about OS X Mountain Lion is that it was a system that brought the Mac experience closer to the world of the iPhone and iPad. It introduced features like the Notification Center, Messages with iMessage, and iCloud integration, which made it much easier to keep everything synchronized between Apple devices. Additionally, it brought security improvements with Gatekeeper and practical tools like Notes and Reminders. Overall, it made the Mac more modern, connected, and easy to use within the Apple ecosystem. Review collected by and hosted on G2.com.

What I don't like about OS X Mountain Lion is that, although it brought many new features, it also left out several older Macs that were no longer compatible. Additionally, some functions like iCloud and the Notification Center could consume a lot of resources, making the system feel a bit slower on devices with limited hardware. It also became more dependent on the Apple ecosystem, which limited those who used services from other brands. Review collected by and hosted on G2.com.

Nice update. The features feel clean and well put together, and it syncs smoothly with my phone. Review collected by and hosted on G2.com.

I was worried that some of my music programs wouldn’t be compatible with the update, and I did have to re-download a few things to get everything working again. Review collected by and hosted on G2.com.

Sometimes, implementing new applications can feel overwhelming, especially when you’re trying to get everything set up and working smoothly. Review collected by and hosted on G2.com.

Ease of use, and the ability to be able to run all development related software Review collected by and hosted on G2.com.

Only supported on Mac infrastructure, and cannot work on other more affordable hardware Review collected by and hosted on G2.com.

I liked how smooth and straightforward the system felt to use. The interface was clean, apps opened quickly, and everything worked well with other Apple services like iCloud, Messages, and notifications, which made the overall experience feel seamless. Review collected by and hosted on G2.com.

Some older apps didn’t always work well after updates, and hardware compatibility could be limiting on older Macs. Over time it also started to feel a bit outdated compared to newer versions. Review collected by and hosted on G2.com.

I find Apple OS X Mountain Lion to be the best environment for getting tasks done in my job. It's an active friendly and embedded system that you can use without any issues or the need for a tutorial, allowing you to get familiar with it quickly. Review collected by and hosted on G2.com.

Even though it's open friendly, I think Apple OS X Mountain Lion needs to be a little more open. Most of the time, if you want to involve this OS in a different environment like Android, Linux, or Windows, it's going to be a bit complicated. Also, with the apps, it can get complicated. We like to be connected to different environments, but there are some issues. Review collected by and hosted on G2.com.
