Mac OS X "Has Mountain Lion been feeling faster for you compared to Lion on the same machine? It's probably not just you: Mountain Lion appears to include improved graphics drivers and low-level graphics subsystem improvements. According to our testing, these improvements result in an approximate performance increase of up to 10 percent. Those improvements can make your current hardware feel faster despite the fact that your CPU can't magically crunch numbers any faster. The changes also lay the foundation for Apple to update OS X's OpenGL support in a more timely manner, which could potentially lead to better graphics performance in the future."

Experiences after 3 days

* Installed on my girlfriends MacBook with Snow Leopard. She is a Mac, I am a PC. (but we get along just fine)

1) Buying it and installing it was easy, but slow (about an hour download and 1 hour install)

2) There was no indication of which programs might not work (as I am used to see before the actual upgrade process starts on Windows)

3) After the upgrade the OS seems to work just fine, but slower than before

4) Mathlab doesn't work anymore because it uses X11. Installing XQuartz solved this

5) Her dictionary application (Japanese-English) doesn't work anymore because it used Rosetta (Power PC). No solution yet

6) "make" doesn't work anymore. She is using XCode for a major codebase (OpenCV) and even reinstalling hasn't solved this

Conclusion: Slower and several business applications stopped working, but she is continuing troubleshooting instead of just downgrading. The "IOS"-ification is strong in this one.

"No solution yet". I think you mean no solution ever (unless of course you try running an old version of PPC osx in qemu). Aren't there other Dictionary applications? Is the application unsupported? Just who is still using PowerPC applications?

6) "make" doesn't work anymore. She is using XCode for a major codebase (OpenCV) and even reinstalling hasn't solved this

You need to install the command line utilities from within Xcode. It is in the preferences.

It should be noted that OSX does not come with gcc any more. Its default compiler is clang but it also has llvm-gcc ( not quite the same as gcc).

In order to slim down OS X and Xcode itself there have been a few changes that caused this problem of yours. Command line tools are no longer bundled by default, but available as an optional download you can trigger from Xcode itself (and they did a good thing let me tell you... no longer having to download 3GB or so of extra stuff at each iOS SDK point release).

So,

1.) Install Xcode 4.4 from the App Store (free).

2.) Open Xcode, and in XCode's Preferences > Downloads you can install command line tools.

3.) Make it system-wide clear where these tools are: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

4.) Accept the command line build utils license: sudo xcodebuild -license

(scroll down and the you have to type accept or agree or something ;) )
