Whatsapp like image compression
- (UIImage *)compressImage:(UIImage *)image{
float actualHeight = image.size.height;
float actualWidth = image.size.width;
float maxHeight = 600.0;
float maxWidth = 800.0;
float imgRatio = actualWidth/actualHeight;
float maxRatio = maxWidth/maxHeight;
float compressionQuality = 0.5;//50 percent compression
if (actualHeight > maxHeight || actualWidth > maxWidth) {

OSX McAfee Removal

Removal of McAfee from OSX

Note: This was written in 2015, it may be out of date now.

There are a lot of commands here which I use sudo if you don't know what you're doing with sudo, especially where I rm you can severely screw up your system.

There are many reasons which you would want to remove a piece of software such as McAfee, such as not wanting it to hammer your CPU during work hours which seems like primetime for a virus scan.

I intend this to be a living document, I have included suggestions from peoples' replies.
