Re-install Mac OSX without DVD drive

[bobspud]

If you are downloading from redhat or oracle they provide an md5 checksum so you can run sum to compare what you have downloaded with what they put up on the site.

The trouble is that mac dont have any md5 sums available because they don't do a legit image so short of a wanderd to the store to buy a copy you are running unverifiable software

By the way slashdot are running this story today.

Quick update - I got the 10.6 DVD and copied to USB stick on a mate's Mac.

I'm now thinking about upgrading to Lion but I can imagine I might want to wipe it again for dev work. Is it possible I can put the Lion download on the same USB stick which has Snow Leopard, or would that require formatting the stick into two separate partitions?

My God d000gh I hope you don't act as clueless on site?

I want to re-install the OS to give me a clean install on my 2008 MacBook; I have the 10.5 DVD it came with but the DVD drive has failed.

Is it possible to do this over a network either by sharing my PC's DVD drive, or copying the DVD onto the MacBook (or some other drive) first?

Copying onto another drive should work fine. Apple don't dick about with copy protection.

If you want to upgrade to Lion, you can get it in the Mac App Store and install it from a USB stick.

Take your spat elsewhere please

So another question I meant to ask - if I'm upgrading is it daft not to go to the newest OS version, given I will use the Mac for development (C++ iPad apps) and web browsing, and don't have any existing apps that need to work? Is 10.7 more resource hungry (this is a 4-year-old MacBook) at all, or more locked down for development, etc?

If you're planning to do iOS development I believe you need Lion to run the latest version of XCode et al.

I'd hardly call asking if I can put two OS installers onto the same USB partition a clueless question for someone who never used a Mac before.

I suppose for a sysadmin like you installing an OS is bread & butter work, but us developers generally have other things to be doing.

Yes you do. But I don't think I especially need 4.x, and the very newest version isn't compatible with CMake, so I might stick with 10.6 until Mountain Lion comes out and then decide what to upgrade to.

Just kidding, I am a developer too,but for things I am not sure about I use this

HTH

I reckon you'll probably have trouble writing for iOS 5.x on anything other than XCode 4, though I may be wrong.

Google doesn't know the answer to everything, for fairly technical and uncommon things genuine human experts are still the best source.


Nick, you're right... on Snow Leopard I'm stuck with XCode 3.2.6 which has iOS SDK 4.3. I don't know if one can manually upgrade the SDK like you can in Visual Studio (sometimes) but I don't know if there's anything in iOS 5 I want to use - my interest is C++ 3D development so I'm only touching iOS itself for the bare minimum of things.
