mac os x

It took less than one minute to boot the Mountain Lion (Mac OS X 10.8.0) system on my notebook before. But after the installation of driver (RTUSB D2870-4.2.6.0 UI-4.0.8.0_2012_09_28.dmg) of a USB WiFi adapter (D-Link DWA-140, RT2870 chip), it took ten minutes to boot. After the login screen, I can see desktop, move the mouse, but can to click anything. Minutes later, I can do everything normally. I searched system logs, and found that as soon as I get back the control, there is a log:

Timeout waiting for IOKit to be quiet

I uninstalled the Wifi adapter driver, my notebook worked fine again. So it must have something to do with the driver.Read more >>

Today, my Mac OS X (10.8, Mountain Lion) broke. Spotlight reindexed the drives, and never finished indexing. When I checked console, I saw crash reports (under System Diagnostic Reports section) like this:

Some MacBook, MacBook Pro or MacBook Air won't wake up from sleep. My MacBook Pro was one of them. I have been googling for two days, and I learnt different ways to fix the problem. Not all the MacBooks can be fixed by the same one solution. Here I collect five common ways to fix the waking up problem together (trying to save time for others). If your MacBook doesn't wake up from sleep, you may try and see which solution works for yours. If any solution works, you may leave a message including your MacBook model and the solution. It may help the others.Read more >>

Solution 1.Select a Startup Disk in System Preferences

I installed Lion on another partition, then migrated the data from Snow Leopard disk to the new Lion system yesterday. Almost everything worked fine, except mysql, php, and mlDonkey did not work, but I fixed these problems.

Restore the scrolling direction of Mouse

System->Preferences->Mouse
uncheck "Move content in the direction of finger movement when scrolling or navigating"

Logitech Control Center

If you use Logitech mouse like me, you need to upgrade the Logitech Control Center application. Only new LCC supports Mission Control.

xcode 4.1

I use macports to install mysql and other tools. Macports needs Xcode. Lion uses new Xcode 4.1. Xcode 4.1 can be download with appstore, and now it is free.Read more >>
