OS X does automatically do some defragmenting, so there's little need for the user to run an app to do that anyway. The main thing you want to avoid with an SSD are apps which move not only defrag the data, but move it all to the top of the partition. The SSD's firmware handles the leveling itself and keeps track of the balancing. Somehow this app just make mess with system files that kill my Mac. OS X don’t need defragmentation, please don’t kill your Mac hard drive by iDefrag. The best way to achieve speed on Mac is switch from HDD to SSD. My Mac take ~60 sec on clear startup, but on SSD I have only 7! Apps runs much faster too.

Came across a to tweak. Only thing I noticed is setting the hibernate mode to 0 made my mac randomly wake up a few seconds after it went to sleep (and happened most often when closing the lid, less often when clicking the sleep button; randomly closing apps seemed to sometimes fix this problem; usually closing Skype and VLC solved this) Set it the 7 now (which was the default I think) yeri$ sudo pmset -g grep hibernatemode hibernatemode 7 yeri$ mount /dev/disk0s2 on / (hfs, local, journaled, noatime). /dev/disk2 256Mi 6.0Mi 250Mi 3% /private/tmp I did indeed, as noted in the above howto/blog post, that shutting down is slower.
Not that much, just a bit. As I usually don’t shut down, I guess this isn’t much of a problem. However, this additional mount point creates a disk on my desktop (or in finder), which is annoying. However, this with /Developer/Tools/SetFile -a V /private/tmp/ But, this option seems forgotten after a reboot and has to be started over. So, tried with then, created a new script with following content: quit application 'Finder' tell application 'System Events' to ¬ set visible of disk 'Volatile HD' to false delay 0.1 launch application 'Finder' And saved it as “File Format: Application” and “Options: Run Only”. The delay line is needed, as without it, finder doesn’t seem to start/reopen its folders/show desktop icons until you click its icon again in the Dock. You can change the delay to 1, but that was a bit slow for me; tried a delay of 0.0001 too, but that gave the same issue as not putting in a delay line in at all.
You can just download the script/application. Drag the application to the Application folder, and add a start up item for it (System Preferences - Accounts - YOU - Login Items; click the +-button and browse till you find your application). Should do the trick. I also changed the ramfs disk size to 128Mb instead of 256Mb, as 256Mb seemed a lot for a disk that was using 10Mb.
