VERY buggy system for designers!
I made the mistake of installing Mountain Lion [on my iMac] on the first day it was released. The system is overall garbage. It fr I made the mistake of installing Mountain Lion [on my iMac] on the first day it was released. The system is overall garbage. It freezes all of my Adobe software that I use for work- like Photoshop and Illustrator. Illustrator will not open or link PSD files and pinwheels until it crashes. I am disappointed with this system and this is the first time Apple has let me down. …

This upgrade cost me $500
Some claim that Mountain Lion Improved startup time vs Lion. New stylish dock. AirPlay. New Safari update is over satisfying. Dict Some claim that Mountain Lion Improved startup time vs Lion. New stylish dock. AirPlay. New Safari update is over satisfying. Dictation (Siri) works flawlessly! More iCloud integration. I saw none of that on my iMAC. And iCloud? who cares. My computer is not a toy - it's a work tool.
I am a professional illustrator / desktop Publisher and this upgrade did not recognize Photoshop CS3, MS Office Works (Word / Powerpoint / Excel etc) nor does it recognize Flash MX - software which I bought when I upgraded to iMac. Luckily I got a free upload to make Photoshop CS3 compatible but I lost at least $500 in other software.
I have been with MAC since 1990 and I am not pleased with these upgrades that seemed targeted for the juvenile home play crowd. MAC should remain a professional tool - not become an entertainment gadget!!! …

It was a major mistake to upgrade it now
Maybe it depends what do you intend to do with your computer and maybe as different software programs start working with Mountain Maybe it depends what do you intend to do with your computer and maybe as different software programs start working with Mountain Lion, it won't be so bad, but right now, I, like many other users have been experiencing issues where everything has slowed down, including browsing the web, and the software programs that used to work well on Lion are either not working at all, or are giving errors. This operating system has been a source of major frustration for me. I'm having a challenge starting Parallels. If you're just using basic Mac software, then you may not mind the upgrade. …

For people with older Macs than Sierra, this is the only available option
Apple Support Communities user tip 3761 describes in more detail upgrade options for Mountain Lion. People with Mountain Lion c Apple Support Communities user tip 3761 describes in more detail upgrade options for Mountain Lion. People with Mountain Lion compatibility, but not Mac OS Sierra compatibility, can upgrade to 10.9, 10.10, 10.11 if they can get the Mac App Store to release one of them for download, and then go up to 10.9.5, 10.10.5, or 10.11.6 to receive the latest security updates for the particular operating system. If you already downloaded 10.9, 10.10, or 10.11 before they were discontinued, the download history of the App Store should allow you to redownload it. Overall, a good system if your software is only compatible with it. Newer operating systems may add newer features, but you should check if those features are worthwhile. Do not upgrade if you have a slow or crashing Mac, and always backup your data before installing anything new. Crashing and slowness usually indicate something not compatible is installed, a directory issue, or a hardware issue. …
