I like that it is intuitive to use-- our org has a wide level of proficiency. Too many changes can halt productivity. Review collected by and hosted on G2.com. What do you dislike about Apple OS X Mountain Lion? It can be tedious to customize features to your computer or find a critical operation. The search bar helps but isn't always accurate in helping. Review collected by and hosted on G2.com. Recommendations to others considering Apple OS X Mountain Lion: It is not the most updated iOS, but it is dependable and a classic. I recommend it to anyone, as frequent updates can really hurt certain programs. Mountain Lion has enabled me to use a software I love, Smartmusic, because the software is compatible. Review collected by and hosted on G2.com. What problems is Apple OS X Mountain Lion solving and how is that benefiting you? I have been asked to teach in a hybrid setting. This allows me to deliver my lesson to two modalities concurrently. Review collected by and hosted on G2.com.

Teacber Enterprise (\> 1000 emp.) 4/29/2021 "Apple OS X Mountain Lion Review" 4/5 What do you like best about Apple OS X Mountain Lion? Apple OS X Mountain Lion is very user-friendly. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

But . . ." 3.5/5 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

For me it took 3 hours to complete the whole process Review collected by and hosted on G2.com.
