Tutorial: "couldn't allocate runtime area" with OsxAptioFix2Drv Slide Parameter

[Krim404]

Many notebooks depend on OsxAptioFix2Drv. Sadly XNU is a lil bit picky with the memory maps.

Thats why some people get a "couldn't allocate runtime area" with an information like even before loading the osx kernel.

Error allocating 0x#### pages at 0x#### alloc type 2
couldn't allocate runtime area

This can be fixed by using the slide parameter on boot. Sadly this has to be calculated based on the used hardware. This is pretty easy when you know where to look. Because the original tutorial got deleted,  i made a tiny step by step tutorial by myself.

 

Be aware: this fix is only suitable if you use OSXAptioFix2, there is a similar looking error when using outdated nvidia drivers. Also do not mix it with the AllocateRelocBlock error (See https://nickwoodhams.com/x99-hackintosh-osxaptiofixdrv-allocaterelocblock-error-update/ )

 

I pushed the tutorial directly into github: https://github.com/wmchris/DellXPS15-9550-OSX/blob/master/Additional/slide_calc.md
