Created April 12, 2014 20:40
Detect if you're being debugged on OS X. Apple's AmIBeingDebugged() won't handle a debugger not using ptrace and is insufficient.

Game speed hack prototype; still WIP
#Game Speed Hack
#Increase x86-64 game by 2x by overriding mach_absolute_time
#May not work on games that call gettimeofday or something else instead
#May not work on games that don't call a time function at all (these areee badddd)
#May also not work if the function is referenced in more than one executable image (eg, local library)
#This is not very robust

Unable to run UI Tests because Xcode Helper does not have permission to use Accessibility.
To enable UI testing, go to the Security & Privacy pane in System Preferences, select the Privacy tab,
then select Accessibility, and add Xcode Helper to the list of applications allowed to use Accessibility.

Using https://developer.apple.com/reference/uikit/nstextstoragedelegate/1534375-textstorage?language=objc which is documented to allow changing attributes
// I'm not using the passed editRange and delta because I've found them to be quite misleading...
// This happens to be a new API (macOS 10.11) so maybe it's not really battle tested or I don't know what I'm doing
// Either way I'd like to support older systems so for portability sake it's easier to not use these parameters
- (void)textStorage:(NSTextStorage *)textStorage didProcessEditing:(NSTextStorageEditActions)editedMask range:(NSRange)editedRange changeInLength:(NSInteger)__unused delta
