I love that it saves as a shortcut on my other devices automatically too! ### 16. apple is well developed for low ram memories **Rating:** 5.0/5.0 stars **Reviewed by:** RAFAEL R. | Markiting, Small-Business (50 or fewer emp.) **Reviewed Date:** December 01, 2021 **What do you like best about Apple OS X Mountain Lion?** 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 **What do you dislike about Apple OS X Mountain Lion?** 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. **Recommendations to others considering Apple OS X Mountain Lion:** I recommend that you always update the software that always comes with news. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** The benefits I received were that apple has a very light and very well developed system, without taking away the fact of the screen and shortcuts that apples products offer. ### 17.

Apple also introduced Messages to replace iChat; this was a quantum leap for cross-device messaging. **What do you dislike about Apple OS X Mountain Lion?** 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. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** At the time, we upgraded our Apple Laptop fleet to ensure we had access to the latest functionality and secure computing environment.

I have used both Apple and Windows 10, and I have to say that OS X has certain features that are unbeatable. I use airplay quite a bit, so airplay is an awesome feature (as well as overall compatibility with Apple products), and autosave enhancements have been a lifesaver for someone who creates and edits many documents. Airdrop is also a super convenient feature. **What do you dislike about Apple OS X Mountain Lion?** As much as I do like the Airplay feature, it is irritating that my older devices (such as an older Apple TV) are no longer compatible with this newer operating system. Certain actions like scroll direction and resize window changes can also be frustrating. **Recommendations to others considering Apple OS X Mountain Lion:** For someone trying to run a business or someone who works remotely, using this system would be ideal. Reliability, security, compatibility with other devices, and ease of use are almost unbeatable. The only issue is the price (which can be quite high compared to other operating systems), as well as incompatibility (or difficulty of compatibility) with non-apple products. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** One huge advantage is syncing between devices, which I use with my iPhone and iPad. This is very important since certain tasks are more convenient to perform on one device over another; this feature is essential. Also, relatedly, is the Airplay feature (which I already mentioned), which is very important for presentations, and also for my own entertainment. ### 33. Apple OS Mountain Lion - Good . . . But . . . **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Music | Small-Business (50 or fewer emp.) **Reviewed Date:** September 08, 2021 **What do you like best about Apple OS X Mountain Lion?** Mountain Lion was a very stable OS platform for people using media software such as Pro Tools 10.3 and early versions of Logic Pro, Final Cut Pro and photo and image editing software. Using a Mac Pro (2009-2012 'cheese grater' models) with plenty of RAM and a solid video card, Mountain Lion provided the speed and power to do most multimedia production. **What do you dislike about Apple OS X Mountain Lion?** Mountain Lion got left behind when Apple's OS moved to Mavericks. Many stable programs were not fully compatible with Mavericks through to High Sierra (although there were some adventurous folks who used older software and were successful). As software multimedia programs upgraded, Mountain Lion could not support programs with the newer bells and whistles. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** I used Apple OS X Mountain Lion for many recording projects ranging from music to post-production to great success. There were few issues with Finder and programs rarely crashed. If someone has older software (such as the above stated programs) and hardware, Mountain Lion is a stable and powerful - but dated operating system. ### 34.

Apple OS user friendly system **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** August 13, 2021 **What do you like best about Apple OS X Mountain Lion?** Apple os is one of the best. I have used both windows as well as apple. Here in Apple, OS X featured are unbeatable as compared to windows. Auto saver is an excellent feature that helps the user to save the doc or edited picture automatically. Also, airplay is the best feature as well as compared with all apple products. **What do you dislike about Apple OS X Mountain Lion?** The worst feature about OS is that older devices like old apple tv are no longer compatible with this new operating sysytem. Certain like scroll down feature is also very irritating. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** The problem solved by OS is the problem of autosaving the data, which sometimes deletes automatically in windows if the laptop shut down due to any situation in the system as well as security problem also solved now we need not worry about our data security as it is secured by apple ### 41. Great OS for Everything **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Higher Education | Small-Business (50 or fewer emp.) **Reviewed Date:** July 27, 2021 **What do you like best about Apple OS X Mountain Lion?** This Apple OS is quick. New apps and windows open in milliseconds, and apps rarely crash, but when they do, the Force Quit option clears up almost all issues. I rarely find myself having to restart the OS to ensure app stability and efficiency. I really like that you can have multiple "desktops" open with different apps and windows. **What do you dislike about Apple OS X Mountain Lion?** I would like more options for multitasking and rearranging windows among one desktop. I would also like built-in FaceTime and iMessage capability so that I can seamlessly move from iPhone to Mac. Some apps (mostly games) will not run natively on Apple OS. **Recommendations to others considering Apple OS X Mountain Lion:** This is a great OS, but you may want to start looking into the latest macOS for the best support from Apple. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** Windows simply was not doing it for me anymore. As a designer and heavy Adobe programs user, I got sick and tired of constantly restarting apps and the PC just to get my workday started. Apple OS X Mountain Lion runs many apps at once and does so with relative ease. ### 42. Great OS for anyone **Rating:** 4.5/5.0 stars **Reviewed by:** Shay M. | H, Small-Business (50 or fewer emp.) **Reviewed Date:** April 30, 2021 **What do you like best about Apple OS X Mountain Lion?** Easy to use, not buggy, a significant improvement over previous updates, increased functionality over the last update **What do you dislike about Apple OS X Mountain Lion?** Many people say battery life has improved, but for me, my battery life has gotten worse. **Recommendations to others considering Apple OS X Mountain Lion:** You can't go wrong with it. It's works smoothly, and the hotkeys make it conveniently one of the best programs out there today. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** Safari has improved, which makes browsing the web easy and more secure. ### 43. Good operating system, but far outdated **Rating:** 3.0/5.0 stars **Reviewed by:** Collin M. | Customer Experience and Marketing Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** May 01, 2021 **What do you like best about Apple OS X Mountain Lion?** I found that this system was very stable and clean. Also, it came with a suite of creative products that I found were really really fun and useful. I used I movie a number of times for presentations, and started making music with Garageband. Also, one feature of Apple hardware is that generally when using USB equipment, there is no need to install a driver, which makes setup for external equipment very easy and stress free. This was especially good while working with end users at the IT help desk. **What do you dislike about Apple OS X Mountain Lion?** It's very outdated in the year 2021. At this point, there are far, far more recent operating systems that can run on the same equipment. One of the things that I didn't like it about the time (and is likely still true) is that it couldn't run much of the Windows proprietary software that I wanted to use, and additionally only ran on more expensive (apple) hardware, rather than on the more cost effective windows machines that I found were available. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** I used it for all the basics, including web browsing, presentation creation, document/spreadsheet editing and creation, etc. While I was using it the system was much more timely, and I found that it filled all the needs that I had. If I remember correctly, you could even play the original starwars movie in the command line, which was a cool feature. ### 44. Snappy, great work OS, intuitive controls, offers many solutions for everyday utility **Rating:** 5.0/5.0 stars **Reviewed by:** Mireya W. | Content Moderator, Enterprise (> 1000 emp.) **Reviewed Date:** April 30, 2021 **What do you like best about Apple OS X Mountain Lion?** I like the ease of use for the user. It makes it very simple to navigate and manage all the programs and files on the computer. Everything is snappy and reaction time is near instant in most cases. Not very related to the software itself but I do enjoy that it is based on a cat. I also enjoy how quickly my peripheals connect. I simply have to take out my wireless headphones and by the time I put them in my ear, they are paired and ready to go. I love that it offers so many features for everyday utility. **What do you dislike about Apple OS X Mountain Lion?** I dislike how the font has changed and things have become rounded at the edges, this is just aesthetic/personal preference for the most part though. I do find it difficult to navigate the landscape of the OS when things move or steps are taken away/added to how things were done before. It doesn't make sense to me that there is not some kind of tutorial or walkthrough after an OS update to guide users through and make sure they have a pleasant experience. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** I'm able to manage multiple apps simultaneously without straing the OS, this is especiallly utilized for video conferences where it can become task heavy. Other than the ability to multi-task well I also find myself utilizing some of the built in shortcuts on the OS. Such as the pinch zoom, scrolling using 2 fingers, and definitely am using the CMD+(other shortcuts) more than a few times dailly. ### 45. Very fast and improved experience - cost is super justified! **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care | Small-Business (50 or fewer emp.) **Reviewed Date:** April 29, 2021 **What do you like best about Apple OS X Mountain Lion?** Mountain Lion definitely loads all programs very quickly, operates at a faster speed, and enables me to nimbly move across my laptop with multiple apps, windows, and tabs all open and running synonymously. It has my older device running like new! I was wary about making the purchase given the price, but I feel my return on investment has been ten-fold! **What do you dislike about Apple OS X Mountain Lion?** Mountain Lion took a very long time to download but I will say it was worth the wait! It could have also been my device so I'm not sure I'd entirely blame the software update for this. **Recommendations to others considering Apple OS X Mountain Lion:** I would say it is definitely worth upgrading your computer and/or devices to OS X Mountain Lion. While typically I haven't sprung for updates - this one is worth it and the cost is entirely justified! **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** - Working on just a laptop without a monitor for 5 weeks - Leveraging multiple windows on browser with multiple (10+) tabs per window - Keeping a VPN and multiple applications running at once - Working across an ops/product heavy org ### 46. Keep Your Macs Updated **Rating:** 5.0/5.0 stars **Reviewed by:** Gary G. | Concierge Technology Consultant, Small-Business (50 or fewer emp.) **Reviewed Date:** July 27, 2021 **What do you like best about Apple OS X Mountain Lion?** Mountain Lion was the latest step in the evolution of the MacOS. Things are snappier and more refined. **What do you dislike about Apple OS X Mountain Lion?** Everything seems to be working well, with no complaints. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** I always welcome the security upgrades that each OS offers. Also, I've long wanted to mirror my screen onto my AppleTV and now with AirPlay Mirroring I finally can. ### 47. I miss mountain lion! **Rating:** 5.0/5.0 stars **Reviewed by:** AHolland L. | Research Technician/Lab Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** April 01, 2021 **What do you like best about Apple OS X Mountain Lion?** I loved mountain lion. It was an excellent software that didn't have too many frills and lovely things to make the computer slow and complicated. Still, I could also use it for more complex coding projects, such as analyzing data from a CRISPR screen that our lab had conducted. I think the interface is just beautiful and well-organized. I will always be a Mac person! **What do you dislike about Apple OS X Mountain Lion?** The only aspect of Mountain Lion that is sub-par is the web browser, Safari. I don't use the safari because it isn't very functional compared to other browser options such as Mozilla Firefox and Chrome. Maybe if I spent a bit more time on it, I wouldn't be as annoyed with it when it doesn't do what I want it to, but I gave up on it a long time ago. **Recommendations to others considering Apple OS X Mountain Lion:** I love it! Don't upgrade to Big Sur, and I have had so many issues with it! I don't know why I updated my software from mountain lion because that was the best, most up-to-date software that still ran well. I think the new software is too new for my 2015 computer, which is rather frustrating as it is only six years old! However, this is an apple problem and not the software. **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** I use it to do everything on my computer! I am constantly using many types of software, and I need to keep everything very organized, so I don't get my projects mixed up or lose anything. I also need my programs to run smoothly because if they don't, then I can't do my job! ### 48. I have been using Apple OS X Mountain Lion for more than 4 years and I highly recommend to use it. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Commercial Real Estate | Mid-Market (51-1000 emp.) **Reviewed Date:** October 19, 2021 **What do you like best about Apple OS X Mountain Lion?** I love almost everything.

The apps open fast, and I really enjoyed the messaging updated with the full bar, took me back to the msn messenger days. **What do you dislike about Apple OS X Mountain Lion?** No one likes the update wait time but Im knew the update would be worth it. I wish the AirPlay would be functional with non Apple tvs **What problems is Apple OS X Mountain Lion solving and how is that benefiting you?** I think it just increase production time ## Apple OS X Mountain Lion Discussions - [Is OS X Mountain Lion free?](https://www.g2.com/discussions/is-os-x-mountain-lion-free) - 1 comment, 1 upvote - [better this app is updated to increase capacity](https://www.g2.com/discussions/42281-better-this-app-is-updated-to-increase-capacity) - 1 comment, 1 upvote - [What is Apple OS X Mountain Lion used for?](https://www.g2.com/discussions/what-is-apple-os-x-mountain-lion-used-for) - 2 comments - [What's after Mac OS X Mountain Lion?](https://www.g2.com/discussions/what-s-after-mac-os-x-mountain-lion) - 1 comment - [Is Mountain Lion still supported by Apple?](https://www.g2.com/discussions/is-mountain-lion-still-supported-by-apple) - 1 comment - [View Apple OS X Mountain Lion pricing details and edition comparison](https://www.g2.com/products/apple-os-x-mountain-lion/reviews?page=2§ion=pricing&secure%5Bexpires_at%5D=2026-08-08+06%3A54%3A53+-0500&secure%5Bsession_id%5D=aba082a9-52d4-4a22-8ceb-3482dee617fe&secure%5Btoken%5D=234cc01b06f5d5868d4d99ec756c25c80704b2ae6d5f3ca0dcee8121ffe90103&format=llm_user) ## Apple OS X Mountain Lion Integrations - [Apple iOS](https://www.g2.com/products/apple-ios/reviews) - [Microsoft 365](https://www.g2.com/products/microsoft365/reviews) ## Apple OS X Mountain Lion Features **Memory Management - Operating System** - RAM management - App Management - File Management **Device Management - Operating System** - I/O management **Backup and Recovery - Operating System** - Data backup **Error Detection - Operating System** - System operations monitoring **Additional Functionality** - Generative AI - Data Security - User Interface - Resource Allocation - System Updates - For Developers - AI Copilot - Desktop Interface ## Top Apple OS X Mountain Lion Alternatives - [Windows 7](https://www.g2.com/products/windows-7/reviews) - 4.2/5.0 (873 reviews) - [Ubuntu](https://www.g2.com/products/ubuntu/reviews) - 4.5/5.0 (2,345 reviews) - [Windows 8](https://www.g2.com/products/windows-8/reviews) - 3.7/5.0 (555 reviews)
