The following is copied word for word from apmouse‘s answer on stackexchange.com.

Under special circumstances, Mac OS X adds the extended attribute ‘com.apple.quarantine’ to a file which was e.g. downloaded from the internet. This can also happen to files within the BoxCryptor Folder. If an encrypted file has this extended attribute set, you receive the “is damaged” error message when trying to open the plaintext file in the BoxCryptor Volume.

x) Open Terminal (Applications -> Utilities)

y) Run the following command (substitute the path):

$ xattr -r -d com.apple.quarantine /path/to/encfs/mount/point

Sometimes I will just apply this to a whole directory of my photos:
xattr -r -d com.apple.quarantine *

Switched from Ubuntu to OS X a year ago, specifically a Macbook Air.  “It just works” is what Apple likes to claim.  While I know that’s marketing, you shouldn’t say it if you can’t back it up.

I feel like I’m using Linux again with all sorts of wifi issues, buts due to driver issues.  A company that controls the platform has no excuses there.  Seriously, I’ll be working and all of a sudden my WIFI drops.  God….

And their trackpad seemed like a nice touch at first, gestures were cool.  However after a year it has given me carpel tunnel syndrome where as a normal touch pad never has.  I like gestures but if it’s a choice between gestures and my health I’ll gladly give up stupid gestures.

Anyway… wifi… some say it’s bluetooh, others speculate other things….. god damnit.  For my tracking purposes…

Updated to 10.7.3. Wifi drops constantly.

Change MTU to 1453
MTU is maximum transmission unit which is the largest packet size allowed over the network.  This setting can be problematic for some networks.  They recommend using 1453 which “is just small enough to maintain a consistent connection with most networks but just large enough to not cause any slowdowns, it’s the magic number and an old cisco networking secret.”
