Most of the recent Macintosh, or Hackintoshs respectively, have the operating system on an SSD, for quick boot-up times. I believe real Macintosh computers employ SSDs only nowadays, but I am not sure...
We all know, that the easiest way to wear down your SSD is, to use it as a swap (virtual memory) device.
Given that your computer is supplied with sufficient RAM for your tasks, you may want to try this:
and disable swap all together.
Presently, with my most recent build (16GB), I am actually trying this.
Hackintosh computers usually employ a regular HDD for mass-storage (or scratch), next to the SSD boot drive. For those boxes, one may consider using the magnetic HDD for swapping. This is a bit more complicated, but still doable:
- boot your Hackintosh into Single user mode using "-s" (no quotation marks)
- mount your HDD, using something like (depending on your setup, disk1s2 is my HDD, mounted on the mount point /Volumes/HOME/):
mount -t hfs /dev/disk1s2 /Volumes/HOME
- now lets make a hidden "vm"-directory:
- link the new "vm" directory to the expected place:
ln -s /var/vm /Volumes/HOME/.vm
you may also link "/private" if you want:
ln -s /private/var/vm /Volumes/HOME/.vm
- for good measures it created empty files (probably not necessary):
touch /Volumes/HOME/.vm/swapfile1since those were the files found first...
- to enable swap, I entered:
launchctl load -F /System/Library/LaunchDeamons/com.apple.dynamic_pager.plist
A from now, my system uses swap (virtual memory) on the magnetic disk, leaving the SSD alone.
Of course, running swap of the HDD might be possible w/o switching off swap in the first place. I have not tried this, but I am certain that (in Single User mode) creating the hidden directory first, copying the swapfiles to it, deleting the previous /var/vm location and finally linking the hidden directory to /var/vm will do the exact same thing.
