Feb 26, 2007 - 12 Comments

No, we don’t mean portable as in a laptop, but portable as in a USB flash drive. Here are articles on how to have a fully functional portable Mac OS X installation, one that gained a lot of attention several months ago, and one that has recently topped the Digg charts. Both will direct you step by step on how to get Mac OS X booting live from a USB pendrive to install. Supposedly, using the same procedure, you can even boot Mac OS X from an iPod! For best performance be sure to use the significantly faster USB 2.0.

    I guess this is cool but it seems completely pointless

    This could be really useful for System Administrators for trouble shooting, being able to boot up from a known working OS install, etc

    This is a great Idea and yes Ed its best used for administrators. My need is to install OS X on a few older MAC’s that cannot read the CD the OS came on. The Flash install works great in this case. Also, I can use the flash drive to run a fully Bootable partition; excellent for securing your Mac by not installing an OS on it and use the Flash which could be locked away.

    if you can run it from a usb drive you can run it on a system…… it just like doing live linux. you can do a boot up with it. fix your partitions on the system. then sudo. so you are in root. then mount the disk and cp to the partition you want it on. if you dont have a boot loader installed on the system already. you can manually install the boot loader of your choice. i prefer chameleon or boothink. just remember it can be as much fun to set up the live version. and make sure you have all your kext’s for the system you are going to install on.

    it’s very useful for those, who downloaded mac os x from the piratebay or similar torrent websites and does not want to go through the pain of fitting 6.8 gb to a single layer DVD-R

    Can I use a Windows PC to download/trasfer Mac OS X software to transfer to my USB flash drive and then use the flash drive to load the Mac OS X onto my Mac???

      No, because you must have a Mac to download Mac OS X Lion from the App Store. If you had a DVD, you could make an ISO or DMG and then copy that to the USB flash drive though.
