Caution: Leave Spindump Alone

On p. 83, in the sidebar “Should You Disable Spindump?”, I explain how to disable the spindump process, which has been implicated in slowdowns after a crash (as it collects data to send to Apple about the cause of the problem). I did this on my own Mac without any problems, but two readers have now reported to me that after trying this, their Macs froze and wouldn’t restart, requiring them to restore their disks from a backup. I can’t explain why that would happen, but to be on the safe side, I recommend just ignoring that sidebar and not disabling spindump. If you do feel the need to try it, be sure you have a recently updated bootable duplicate first—just in case!
