I've disabled memory swap (compression) for testing purposes with command: sudo nvram boot-args="vm_compressor=1". I tried re-enabling it with sudo nvram boot-args="vm_compressor=4", tried this as well: sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist and this sudo nvram -d boot-args I also disabled "system integrity protection" but nothing's working, anybody knows what to do? will be grateful for help as I have to suffer with windows xp now..
