tip : put a OSX 10.8 “Mountain Lion” installer on a USB-stick

If you just have one Mac you want to install OSX 10.8 “Mountain Lion” on, you can just (buy and) download the installer from the Mac App Store.

But if you need to install OSX 10.8 “Mountain Lion” on multiple Macs, the fact that the download process regularly is very slow, will make you want to skip the downloading if possible.

You can do so easily by creating a dedicated USB-stick with the OSX 10.8 “Mountain Lion” installer on it, which is quite easy :

– get yourself a brand-new 8GB USB-stick

– buy & download OSX 10.8 “Mountain Lion” from the Mac App Store, but… you need to make sure the installer will not be ‘cleaned up’ (= deleted) after the installation has finished : the easiest way to do so is to wait for the download to complete, and then when the installer window pops up, do not start to install right away ; first, go to the Finder and into the Applications folder, then right-click on the “Install OSX 10.8 Mountain Lion” application, and select “Compress “Install OSX 10.8 Mountain Lion””… then wait for the compression to complete… when that’s done, you can continue to the installer window and install OSX 10.8 “Mountain Lion”

[ if you’ve already installed OSX 10.8 “Mountain Lion” and the installer has already been ‘cleaned up’ (= deleted), you need to re-download OSX 10.8 “Mountain Lion” from the Mac App Store ]

– download the “Lion DiskMaker” app from here :

http://blog.gete.net/lion-diskmaker-us/

– then double-click on the .zip-version that is now/still in your Applications folder ; that will place the original installer application back

– then run the “Lion DiskMaker” app, and follow the instructions given

…it’s that easy

Note :

– additional instructions can be found on the page that you’ve downloaded “Lion DiskMaker” from

– reformatting of the 8GB USB-stick will be done by the “Lion DiskMaker” app also

– it is highly recommended to create the installer on a dedicated USB-stick ; even though it is possible to burn the installer to a DVD, do not do so, since that will be extremely slow to startup from during installation – also, do not put the installer on a (partition of) a external drive that has other data on it… it might wreck your data if things mess up during creation, and it’s not as practical for actual use…

Apple is getting everything in place for the release of OSX 10.8 “Mountain Lion” due later this month.

The names of the Macs that will be able to run OSX 10.8 “Mountain Lion” have been published on the Apple website :

http://www.apple.com/osx/how-to-upgrade/

From eldest to newest these Macs are :

– iMac “mid 2007” or newer (so any “Aluminum” iMac)

– MacBook Pro “mid/late 2007” or newer (so any MacBook Pro with an NVIDIA graphics card)

– Mac Pro “early 2008” or newer (so any Mac Pro with the Xeon 5400 “Harpertown” processors or newer)

– MacBook Air “late 2008” or newer (so any MacBook Air with Thunderbolt or MiniDisplayPort)

– MacBook “Aluminum” = “late 2008″ (so the 13” MacBook Pro look-alike)

– MacBook “White – early 2009” or newer (so only the ‘original’ white polycarbonate design versions that have an NVIDIA graphics card)

– Xserve “early 2009” (so only the latest generation with Xeon 5500 “Gainestown” processors)

– Mac mini “early 2009 & late 2009” (so only the original Mac mini design that have an NVIDIA graphics card)

– Mac mini “Aluminum” = “mid 2010” or newer (so any Mac mini of the extra flat redesign)

…that’s the bad news (for some  – those of us with older Macs…)

and the good news is :

you don’t need to have MacOSX 10.7 “Lion” installed to upgrade, you only need MacOSX 10.6 “Snow Leopard” with the “Mac App Store” application (since OSX 10.8 “Mountain Lion” is only available from the Mac App Store…)
