Safe place to download Yosemite

@bmaz a checksum of what, exactly?

To checksum a bundle such as the one used by Apple (its installer .app) you'll probably need to install something that's not integral to OS X.
 
I was speaking of the Yosemite Installer for 10.10.2
I ran this script in the terminal to check it.

shasum /Applications/Install\ OS\ X\ Yosemite.app/Contents/SharedSupport/InstallESD.dmg

I got back the checksum, but I have nothing to which to compare it.

I only found it in one thread. Apple's site was no help, at least as far as I could find. My other concern is that I can't get an "Apple Signature Check" on the download.

I know Apple publishes the SHA info for "updates", but I have not noticed them posted for full OS installers.

Maybe if I was a Apple Developer...

It's hard to wanna trust this download, but I might have to.
 
Pretty cloud services like Dropbox miss-handle .app extensions.. They treat it as a folder.

I guess I could zip it, but weather it would be compress enough to share without the recipient needing DB account..

I'll give it a shot... Take few days to upload though.

I'm guessing it won't compress enough to fit in the free 2GB DB account.
 
Actually i have a Dropbox Pro account... Its more to do with Dropbox not able to recognize .app files instead of individual files/folders as it does normally, thus the need to .zip first

Back to basics, for a moment … did you never use the App Store to download Yosemite?

It is still (or should be) on the Purchases page of the Store, for anyone who did so. I see it now, with App Store in pre-release Sierra.

From your earlier post –

– I assumed that the check related to a download through the Store. If so, then it will probably be better to focus on getting the Store to work as expected in your situation.
 
I missed the boat on being able to download 10.10. I didn't realize Apple removed the ability to download previous versions of OSX upon release of a new version.

OK, thanks.

So … on what, exactly, could you not get an Apple Signature Check? (Can you tell us, or was it something from a dubious source?) I can't quite visualise that check.

PS I reckon that a suitable approach to Apple support should result in you getting a redemption code. I know that it has been done for other versions of the OS.
 
There is another solution, it is to take a USB thumb drive to an Apple Store and ask them to put the Yosemite installer on the USB drive. I have not tried this, but I have read others recommending this solution. I do realize that this is not a "download" solution, but it is another alternative.

Here is the reference to the Apple Signature Check:
https://support.apple.com/en-ap/HT202369

I emailed and called Apple several times trying to get them to give me a redemption code. No response on the emails, and no luck with talking to 3 different representatives.

I have not tried asking for the USB solution. When I went to the store, the only help they could offer was to bring in the machine. That's not going to happen, though.

@bmaz thanks, what was the name of the .pkg file that you checked? Sorry, ignore that, I somehow missed the uppermost App Store part of that article. Still, I can't visualise what you checked; if it was not through the App Store then I'm curious about the nature of the .pkg … but I'm probably dragging that out unnecessarily!

Normally I might offer to arrange a copy of my saved installer (stored here on ZFS, so I can be sure of its integrity) but that ZFS pool is probably within an encrypted Core Storage volume and the only working Mac that's available to me is almost unusable with pre-release Sierra in normal mode.

What I was able to get was a .zip file that unzipped into the Yosemite Installer. When I followed the instructions to check the signature, as per the link in #91, I couldn't find a signature icon, or a lock icon.

It sounds like perhaps you have downloaded the installer.dmg itself and not the full .pkg file that would have the certificate. What happens for example if I downloaded El Capitan today from the App Store is I would get a .pkg file with data inside that file identifying that .pkg as having been downloaded with my AppleID. And that .pkg file would have the certificate mentioned.

Then inside that .pkg file is the installer.dmg. That file is the same for everybody and would have the SHA that matches other downloads. That installer.dmg is not linked to an AppeID.
 
Not sure if it helps, but this is the results for the last download I made on July 6, 2016.
