I didn't see a thread for this nor did I find any thread that had to do with this topic when I ran a search of it. I also believe this thread fits best here since it includes Intel Macs and PowerPC Macs. Or AMD Macs if you really did modify it good enough. Don't forget to specify whether or not you've got an SSD or HDD. Post full machine specifications if you want. My HP Netbook, surprisingly has the fastest boot time of all my machines, which is 7 seconds under Windows 8, but if it's booting into Windows 7, it's put into third place with 26 seconds. It's only got a 160GB Hard Disk Drive. But that's a bit off topic here I think. My Mac, a PowerPC G4 Mac is in second place of all my computers, with a boot up speed of 13 seconds, believe it or not. It's got a 120GB hard drive that runs at 7200RPM. What's your boot speed?
