Bootable OSX Lion DVD Image included? True or False?

Posted:
in macOS edited January 2014
I've heard on the grape vine that OS X Lion, when downloaded from the AppStore, will have a bootable DMG image included in the .app package (right click > show package contents). Apparently, this disk image (Install.dmg or similar) when burned to a DVD gives you the full install procedure as with previous versions of OSX, with access to disk utility and install options for a clean install.



I am not sure if this information is true or not, I'm not a registered developer and do not have access to the RC install packages, but if anyone here is a developer and can confirm this, then OS X Lion just became that little bit better.

    You act like you can't do a clean install directly from the installer package that you download. You can.



    Lion also makes a partition on your drive that contains itself and other tools in case you ever have to fix something. No disc is ever needed unless you buy a new drive.

    This is the first time I have heard this, either I missed a post about it on Ai or its only something the developers knew about. (Probably the former knowing me).



    Drive failure is something you have to consider, as well as whacking the disk into another Mac without having to re-download on the other system. It may just be me being old fashioned, but I've always proffered having my OS on some form of physical, bootable media. Many people on Ai after the announcement wanted the same thing.



    Also, you never answered my question

    Oh, right. Sorry.



    You can just take the DMG that contains the Developer Preview (any of them), burn it to a disc, and it'll work perfectly fine as an install disc. I can't imagine that any ".app" packaged version of Lion will work any differently if you really...



    ...REALLY...



    ...want a disc of it.

    I get it, I get it, optical disks == bad joojoo.



    Thanks anyway, I think a few people will be happy about this

    Could also mean a bootable USB Pen Drive for MBAs.

    Heck, we need Thunderbolt NAND drives. No sense in waiting for USB anymore!

    ...as long as it is readable. Because burnt CDs/DVDs (as opposed to pressed/stamped CDs/DVDs) start degrading (by osmosis) from the minute they were burnt. Some will already be unreadable after 2 years. All will be unreadable after 10 years!



    Pre-Lion install CDs/DVDs were all of the pressed/stamped variety. So they are still readable.

    I have copied PS1 games that are over ten years old, they work fine. High quality CDs and DVDs (you can tell quality from how dark the bottom of the disk is) will last for years. I have Backup DVDs from 2001, they're now ten years old and they still read perfectly at full speed.



    Cheap disks will die and very quickly, high quality disks will last you a lifetime (if stored correctly).

    Wow. You're not just completely full of crap about what you think Apple will do with cloud software, you're completely full of crap about EVERY aspect of computing.

    Thanks. I'm loading up a fifteen year old burnt CD right now, works fine. I have DVDs about the same age; they're okay, too.

    How's that congenital lying treating you? That's certainly not your PART TIME job, at least.



    In all seriousness, stop the FUD.

    Since there is a possibility (probability?) that optical drives may disappear from Macs, would it be a good idea to:



    1. Put Lion OS or the next OS version on a thumb drive?



    2. Would the 4 MB Lion OS fit on a 4 MB thumb drive or would it be better to put it on an 8 MB?

    (that sounds stupid, doesn't it?)



    3. What are the down sides, if any, of having the OS on a thumb drive?



    4. Would the same method be used to put the OS on a thumb drive as on an optical disc?

    I'd love a 4 megabyte Lion install. I miss when OS' had to have size requirements. Code was tight and clean.



    The GM reports as 3.76 GB when "Get Info'd" within the GM itself. Removable media will be reported as the manufacturer describes. So a 4GB drive will show up as 4GB. I'm pretty sure it will work fine.

    Is installing over USB faster or slower than installing via DVD?



    Whichever is slower is the downside. A flash drive you can scratch all you want and it'll still work. A DVD you can scratch once and instantly ruin. Though it's unlikely you'll leave a DVD in your pants pocket through the wash.

    Operationally, no. The instructions are different. The outcome, of course, is the same (a bootable piece of metal and plastic from which you can install Lion).

    Add that to the fact that what he said isn't true in the first place, you'll have yourself a copy of Lion on ANY DVD that will last far past the lifetime of the OS.
