Following 5,29 GB download, OSX Mavericks’s installer stated 34 minutes total installation time, and while the volume was an SSD, it didn’t install faster than announced (was closer to 45 minutes). Moreover it took more than 5 minutes to complete the installation while stating one minute remaining (we could check it wasn’t stalling by looking at the log file through the menu). When restarting it added a 7 minutes remaining step, however this one completed in 2 minutes.
In fact the installer kept all previous user files and custom system/library components (audio plugins and applications specific libraries and settings) and preferences (even mysql and apache document root), then providing a fully working upgraded system (no backup required).
The new Apple Maps applications is stunning, with perspective varying when looking from top, and even allows full exploring/navigation mode (from sides with various depths). Details and experience are far more better than with Google’s solution.
Finder windows list view use lighter gray for files informations (as to focus on files names) and sort columns labels. It feels even more responsive than Mountain Lion (that was faster than previous versions). Rendered icons in grid view look sharper, that may come from either optimizing or use of a darker background. Also icons in Preferences panel are redesigned and larger.
The new activity monitor shows more usefull informations, and we now see that non running/front applications use minimal resources after a while (including the activity monitor).
Using benchs show huge performance increase in FFT (on par with Snow Leopard – was way slower in Mountain Lion), that may be interesting for audio applcations. The new OpenGL is 44 percent faster than Mountain Lion’s one (was slower than Snow Leopard). User interface tests results were even greater (50 percent increase) than with Mountain Lion.
UPDATE : php module hase to be activated again (uncomment loadModule in /etc/apache2/httpd.conf) and php.ini has to be created and edited for mysql socket (sudo cp /private/etc/php.ini.default /private/etc/php.ini, then sudo vi /private/etc/php.ini and set mysql.default_socket = /tmp/mysql.sock in [MySql] part). Finally config.inc.php in phpMyAdmin has to edited to add $cfg[‘Servers’][$i][‘user’], $cfg[‘Servers’][$i][‘password’] and set $cfg[‘Servers’][$i][‘host’] to 127.0.0.1 (socket problem if localhost).
