Sam,

Here are my suggestions from my personal experiences:

1. For blocking apps the best firewall app I've seen for Mac OS X consumers
is: Little Snitch, as it does per application blocking

2. Use Google Chrome when browsing the net, it's not perfect but in my
opinion is the most secure web browser.

3. Disable ALL automatic updates when going into a hostile region, to
prevent FinFisher

attacks

4. Use full disk encryption, I prefer WinMagic SecureDoc for OS X, but
FileVault works too if you don't want to spend the money. I won't use
FIleVault because to the best of my knowledge it only supports AES 128 bit
encryption, not 256 which is pretty much standard these days. HOWEVER BE
WARNED authorities in foreign countries may detain you until you give them
access to your machine, therefor any really sensitive work I highly suggest
a Windows VPS with Remote Desktop to prevent having any sensitive data on
your machine if it is lost, stolen, or seized.

5. Subscribe to a remote VPN service in a 3rd party country, for ease of
use I'd suggest a PPTP VPN provider. If you absolutely have to run any
system or software updates, only do so when connected to your VPN provider.

6. Use Gmail, with two factor authentication enabled: Google
Authenticator<http://support.google.com/a/bin/answer.py?hl=en&answer=175197>,
e-mail stored on your own laptop is not always a good idea.

7. As for cloud storage I would suggest the use of
CloudFlogger<http://www.cloudfogger.com/en/>with Dropbox, with a
strong password! Some people will tell you to use a
TrueCrypt container with DropBox, I say nay, The reason being CloudFogger
does file-by-file encryption which is important so when you change a single
file, you don't have to resync the entire container file, only the changed
file. Saves a lot of time, and bandwidth. Another cloud provider that
includes encryption is called "SpiderOak <https://spideroak.com/>",
although I personally like to keep my encryption and storage
provider separate. CloudFogger + DropBox will also run on iOS or Android so
you can access your files. Don't forget to turn on full device encryption
on your Android phone as well.

8. Always have the TOR bundle handy.

Good luck,
