- Java JDK error
The first error I've catch was an error in Java JDK. A popup was shown with this message: "To view this web content, you need to install the Java Runtime Environment."
In order to fix this, you need to install the latest Java 8 JDK.

- Brew postgres error
I've postgresql installed via brew, but after updating to Yosemite it stoped working.
First you will need recreate some paths that were deleted on update:
mkdir /usr/local/var/postgres/pg_tblspc
mkdir /usr/local/var/postgres/pg_twophase
mkdir /usr/local/var/postgres/pg_stat_tmp
touch /usr/local/var/postgres/pg_tblspc/.keep
touch /usr/local/var/postgres/pg_twophase/.keep
touch /usr/local/var/postgres/pg_stat_tmp/.keep
Second you will need to reload postgresql after an upgrade:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
