However how do I actually check the .dmg file that contains the installer is the right one?

If I run:

Code:
gpg --verify bitcoin-0.13.0-osx.dmg

I get:

Code:
gpg: no valid OpenPGP data found.
gpg: the signature could not be verified.
Please remember that the signature file (.sig or .asc)
should be the first file given on the command line.
That's because the files themselves are not pgp signed and do not have any signatures.

Greetings and thank you very much for this guide. I try to work best practices into as much of my computing as possible but using GPG has defeated my time/need/interest matrix for awhile.

What files do contain the signatures that we are supposed to be verifying? The OP's guide says,"Bitcoin developers and other interested people sign every release of Bitcoin Core using gitian." I thought this meant if I download a .sig file from the gitian page on GitHub, I could run 'gpg --verify' on the new program I downloaded from bitcoin.org to verify its authenticity.

After I've imported the public PGP keys & downloaded the assert.sig file from GitHub, when i run gpg --verify I get the following:
ninjasmurf$ gpg --verify /Users/ninjasmurf/Desktop/bitcoin-dmg-signer-build.assert\(1\).sig  /Users/ninjasmurf/Desktop/bitcoin-0.13.0-osx64.tar.gz
gpg: Signature made Wed Oct 14 11:04:19 2015 EDT using RSA key ID 2346C9A6
gpg: BAD signature from "Wladimir J. van der Laan <laanwj@gmail.com>" [unknown]


Why does this come back with a BAD signature?
Thanks in advance. Have a sweet day.

is BFL going to ship before the end of the year? tip your answer.
Yes = 1hWezTD2J55HnvNrFAzhfpXkrDi3DLK1E or No = 13VMhP3seeXU5aej82R89AJV4X32x81Nju

You can receive regardless of your sync state. However, if you want to be able to see and spend the Bitcoin, you will need to be synced. You can enable pruning so that the blockchain doesn't take up as much space.

No. It can and will use any previously downloaded data and your previously used wallets as it did before.

How about release version 0.13.1 downloaded from bitcoin.org.
Does it have more stable security than the 0.13.0...

Do you even know what this thread is about? The security problem isn't inherent to the client itself, but rather due to potential state-sponsored attacks on websites from which users would normally download. If you compiled 0.13.0 yourself, you would not have to deal with this risk. The same applies for 0.13.1, i.e. you should also verify the download.

Slightly off topic, my PortableApps version of the BitCoin Wallet crashed the night before last with a window telling me to update to the latest version (so, it's on topic concerning the latest version and upgrading same) I've made appeals on BCT in the past to have the PA version of BitCoin Wallet updated but they have fallen on deaf ears.

So, in light of this thread and my BTC Wallet crashing solely because it needs to be upgraded, can someone cast their eyes on this: http://portableapps.com/search/node/bitcoin

Thanks.

The official binaries includes zip versions which do not need to be installed and can be run on any computer provided that it runs the right OS. You can just set it up with a shortcut or something to have the datadir point to your USb drive.

Thanks for the info - I'll give it a go (and will back up my wallet.dat etc etc)

I didn't get which version of GPG verifier to download. Would appreciate some help..

I'm personally using Gpg4win (Windows only) and I guess almost everyone else on the forums is using the same thing : https://www.gpg4win.org/ , If you don't know much on how to use it (beside verifying) then you could check this tutorial https://www.deepdotweb.com/2013/11/11/pgp-tutorial-for-newbs-gpg4win/
