Gatekeeper added to OS X Lion 10.7.5

Apple Adds Gatekeeper to Lion with OS X 10.7.5

According to the article the default setting is the middle one, which is "Mac app store and identified developers". I wonder what an identified developer is. I suspect that open source developers might not be "identified". Which means you won't be able to install software like vlc without changing the setting in the control panel. But before you could do that, you would have to know about gatekeeper first. I think 10.7.5 is going to cause a lot of headaches for a lot of people.

Revisiting OS X

Started using OS X again (Lion), and was a little happy to see that despite all the changes, dmesg still works.

This post is a good pointer to get write capabilities for ntfs on Lion.

Guide: Enable native NTFS Read/Write in Snow Leopard - Mac Forums

Guide: Enable native NTFS Read/Write in Snow Leopard - Mac Forums:

"I am sure many of you heard that Snow Leopard was supposed to have native read/write for NTFS partitions. Apple supported NTFS R/W in older SL builds but I guess decided to not to go with it for some reason, however support is still present.
For this, you need to modify your /etc/fstab file to mount NTFS partitions for read and write.

First, uninstall NTFS-3G/Paragon if installed.
Open Terminal.app (/Applications/Utilities/Terminal)
Type 'diskutil info /Volumes/volume_name' and copy the Volume UUID (bunch of numbers).
Backup /etc/fstab if you have it, shouldn't be there in a default install.
Type 'sudo nano /etc/fstab'.
Type in 'UUID=paste_the_uuid_here none ntfs rw' or 'LABEL=volume_name none ntfs rw' (if you don't have UUID for the disk).
Repeat for other NTFS partitions.
Save the file (ctrl-x then y) and restart your system.

After reboot, NTFS partitions should natively have read and write support. This works in both 32 and 64-bit kernels. Support is quite good and fast, it even recognizes file attributes such as hidden files."

This worked for me.
