Photoshop: Saved Gif Turns Red When Adding Text

Sometimes you search something on google, and the most trivial answers do not show up. So I figured as a self reminder, I’ll post this here.

Does your background turn to a red tint when you add text to a GIF image saved as a PSD?
Well, do this to fix:

Open the .GIF in Photoshop. Covert the image to RGB (Image > Mode > RGB). Gifs are Indexed color and need to be converted to RGB. You’ll then be able to add layers and edit…then save as .PSD. or whatever format you choose.

Hackintosh doesn’t connect via ethernet

Does your Mac Ethernet/Wireless keep giving you a fake 169.254.x.x ip address?

Recently I started running Mac OS X Leopard (10.5.8) on my spare computer. It worked fine for a few days until one day when I changed my router, my Mac stopped connecting to the router. It would repeatedly get a 169.254.x.x ip address through DHCP. If I set the IP address manually, it would show that it assigned the IP address, yet it would still not “properly” be connected in the background.

So here is what I did to fix this problem. Open up Terminal using Spotlight. And type the command:

sudo ifconfig en0 ether 00:11:22:33:44:55

It will then ask you for your password. That’s it.

Explanation:

sudo: Gives you administrative power

ifconfig: the program that interacts with all your connectivity configurations

en0: the interface’s name, it could also be en1, en2, etc. (depending on the amount of network wired/wireless cards you have)

00:11:22:33:44:55: the mac address, pick whatever hex combination (i.e. only use characters 0-9 and a-z)

Please share your experiences.
