Penguin! Posted May 22, 2011 Share Posted May 22, 2011 You should be able to, assuming Disk Utility sees your disk and your BIOS allows you to boot from USB devices. (It should) I have installed OS X Leopard onto external drives before with success. Good Luck! Link to comment Share on other sites More sharing options...
Laszlo Lebrun Posted May 23, 2011 Share Posted May 23, 2011 Hi ! Can I install Mac OS X Leopard on an external usb hdd on laptop acer extensa 5220 ? Intel Celeron 560 M , 2 GB of RAM.Is there any difference between this type of installation and standard installation on internal hdd ? It usually works. You have got basically two ways to boot: a) from a chameleon session on your HD. from a chameleon session on your external drive, you need then to start with F12. Sometimes having a chameleon bootloader on both can lead to unwanted loops. I use to use first option on my private notebook, good way to recover crashed OSX sessions from the USB drive. I use to use second option on my corporate notebook, good way to use it privately on a bus trip without leaving anything on my corporate HD. Go, go for it.
