I downloaded OSX 10.8 last night and let the update run. What an infuriating mess. Specifically: 1. Display on 13" Macbook Air looks washed out, over saturated in many apps. Adjusting brightness, fiddle with other settings, download third party apps - nothing seems to help. It isn't all apps, as my plain old Pro shell looks fine - black is actually black, not some weird radioactive glowing gray. 2. XCode command line tools broken. Much Googling, find a complex solution, then determine that it's easily resolved by re-installing the tools from within the updated XCode app. 3. Python completely screwed. Download and install from DMG - seems to have cleared it up. 4. I use Maltego all day, every day, and it depends on the Java Runtime Environment. Apple site doesn't have anything that works in 10.8, main search for Java on Oracle doesn't have anything, dig with Google and find the following: -rw-r--r--@ 1 x staff 102002567 Aug 12 09:34 jdk-7u4-macosx-x64.dmg Click it. Repeatedly. Nothing. Refuses to open. 5. Google Chrome looses ability to play Flash - no more YouTube. Go to http://google.com/chrome, get the DMG. This one ALSO refuses to open. -rw-r--r--@ 1 x staff 43843950 Aug 12 09:56 googlechrome.dmg 6. Open Mail.app to send angry note about all this stuff to a colleague. Ut-oh, GPG Tools does not work with Mail.app version 6. Contact developers, it's a small team, they say it will be weeks before the update becomes available. I have a $1,200 two pound paperweight here. How do I download a 10.7.4 install DVD so I can get back to work? ---------- Oh, and I did permit third party apps to load by visiting System Preferences | Security & Privacy and making the needed change in the General tab. ---------- Can't open PNG, JPG, or PDF using preview. I wonder what else isn't working ... grrr. ---------- OK, a light at the end of the tunnel. Libre Office is broke, too - won't start w/o the Java Runtime Environment. The official software update won't find what's needed, but this program knew where to get the right Java stuff, and my Maltego is restored.
