iDefrag lets my computer go to sleep!

iDefrag is designed to allow the display to sleep, but not the computer as a whole. This should mean that you can defragment your system without worrying that your display will suffer burn-in or display persistence issues (LCDs do exhibit display persistence, though it’s only temporary… you can fix it by putting a white background over the affected area for a while).

Unfortunately we have received reports from some users that iDefrag isn’t making any progress when the display blanks; we now suspect this might be a graphics driver problem as this definitely doesn’t happen on all machines. If you are affected by this issue, please send us a system profile report (you can get this by going to the Apple menu, then “About This Mac”, then clicking “System Report…”, followed by “File” > “Save…”).
