Upgrading to Mavericks from Mountain Lion

[NoCaps]

hey all, I'm trying to figure out how to upgrade to Mavericks from Mountain Lion, i've been using ML for a few months and realised I should probably definitely upgrade. i used the command on mavericksforever.com to get a copy of the mavericks installer, but when trying to run it it just tells me that "an error occurred" (see attached) and closes. running with the Installer Log turned on gives me these errors:

Checking Software Update catalog URL https://swscan.apple.com/content/ca...n-lion-snowleopard-leopard.merged-1.sucatalog
Could not add SWU product
Install OS X Mavericks[841]: Error!! Error Domain=ISErrorDomain Code=14 "Unknown Error." UserInfo=0x7fab7aaeb2c0 {NSLocalizedDescription=Unknown Error.}

not too sure how to fix these, previously it gave me a certificate error but installing Aqua Proxy fixed that. it would be really nice if i could upgrade rather than doing a clean install as i have a lot of junk on here 😛

Is there a reason you absolutely need to do a live install? My first thought would be to create a bootable installer as per Mavericks Forever, boot into it, and install Mavericks over your current drive (ie, don't wipe it in Disk Utility.)

I have done very few in-place upgrades in my life—I like doing clean installs when I upgrade to a new OS—but my understanding was that this was the same as doing an app store upgrade.

Mainly just for convenience sake, i don't have many usb drives laying around to use for a bootable installer (the last time I installed OSX i had to use my ipod nano to boot the installer off of, which worked but went exactly as slow as you'd expect it to be) - but if installing it the way you say won't wipe all my stuff then I'll give it a try

I thought the one downloaded from there doesn't have the right structure to be installed via app (something about the dmg structure being udzo). If you really want to, you could download from internet archive the MAS release

I think it's theoretically possible to use Disk Utility to add a partition on your boot disk, write the installer to that partition, and then boot that partition. But there's always some risk of data loss when you do this, especially because HFS+ is a pretty crummy filesystem. I think it would be faster to use your iPod Nano.

Alternately... I don't know what your financial situation is like, but 8 GB USB drives are really, really cheap nowadays. For example, here's one for $6 on Amazon. (There's nothing special about this one, I found it after 60 seconds of searching. Also, for even $1 more you can find drives with 4x the capacity.)

By the way... your lack of access to external storage media is worrying me a bit. If that means you also don't have your data backed up on an external drive somewhere, pretty please drop literally everything else and and fix that as soon as possible. It's not worth it.
