Macos – How to increase the performance of Mac OS X

macmacososx-snow-leopard

What are the best-resources to fine-tune Mac OS X (10.6.4, Snow Leopard on a 13in unibody MacBook). I've been a long-time Windows users and bought a Mac couple of years ago.

In Windows, I could have cleaned registry, removed un-necessary services, use msconfig to tune etc.

With the usage and all the Apple updates, looks like the OS is sluggish. Any pointers to resources online will be helpful. I tried clearing Browser cache, flush DNS etc.

—UPDATE—-

Thanks for the responses, I have used Onyx and it helped ..

I have also replaced hard-drive with SSD and the machine is much faster. (Unibody 13 inch Macbook 5,1 ~ 2008)

And upgraded to MountainLion and enabled SSD Trim.

This is the article you are looking for.

If your OS feels unusually sluggish, it may be a problem with a process you don't know is running (like mdutil indexing for spotlight search), lots of disk thrashing due to a memory shortage, or perhaps some misconfiguration is causing lots of errors.

I would check the Console application to see if there are unusual messages. And use the Activity Monitor to check if some process is taking up too much processor time.

Most of the time additional tuning of Mac OS X is unnecessary, as long as the regular maintenance scripts are running properly. The best way to increase performance is to buy more ram and/or a solid-state drive.

Macos – Android SDK emulator freezes on a Mac running OS X 10.6 Snow Leopard

I was digging around the other day and saw this message appear on the terminal: emulator: warning: opening audio input failed I've seen this message many times before and I had always assumed that it was because the emulator didn't support sound or something like that. But I decided to try an experiment that one particular day. Turns out the emulator has a "-noaudio" command line option, and when I ran it with that, it worked!! So now I just run emulator with the -noaudio option always, no freezes. No sound support either, but at least I can run the emulator now.

Now, that works if I manually call the emulator from the command line. What about when the Eclipse ADT plugin calls it? Well I was feeling rather lazy at that point and didn't want to dig around in the ADT plugin to see if it had a "add these command line flags whenever running the emulator" option, so I made a little "wrapper" shell script for the emulator command that always adds the -noaudio option. It's a bit of a kludge, but it works. Here's how: (note: $ represents the shell prompt, don't type it yourself)

$ cd <WHERE YOU INSTALLED THE ANDROID SDK>/tools
$ mv emulator emulator.real
$ cat > emulator << EOF
#!/bin/sh
exec <WHERE YOU INSTALLED THE ANDROID SDK>/tools/emulator.real -noaudio $*
EOF
