kagaku Posted November 27, 2009 Share Posted November 27, 2009 After recently upgrading to 10.6.2 and then having to upgrade my VoodooHDA kext, I also noticed the AppleHDA and HDAenabler kexts in my /sys/lib/ext folder; I removed them without issue as I did not want to chance any sort of conflict. My question is regarding the other ~150-200 drivers in that folder, many that are obviously not used for my system (anything ATI or Intel GMA) - however I am curious as to whether or not they're using any resources? My first guess would be no, they're not being loaded and therefore not using any resources; however does the system look at these drivers at any point during the boot to determine it's not using them? Just a curiosity. Link to comment https://www.insanelymac.com/forum/topic/199702-unused-drivers-do-they-use-any-resources/ Share on other sites More sharing options...

Just a curiosity. My understanding is no.they don't use any resources. As to what point during boot they are looked, don't know, good question. You can see what has been loaded In System Profiler..

Superhai Posted November 27, 2009 Share Posted November 27, 2009 Only when it needs to update the cache is OSX looking at them. I recommend that you do not delete any of the files in the extensions folder, unless you are positively sure they cause problems. The most common issue for hackintoshers are missing kexts, forget to update cache and hacked drivers installed by "distros".

el coniglio Posted November 27, 2009 Share Posted November 27, 2009 <joke>Certainly it consumes disk space (well, it is a resource).</joke> Imo, at boot time the info.plist file is parsed, you can easily verify this using the 'ls' option to show the last access time, I think a <code>ls -lu /path/to/somethig.kext/Contents/Info.plist</code> will do the job. If it doesn't work you can use <code>perl -e "print localtime((stat(\"path/to/somethig.kext/Contents/Info.plist\"))[8]).\"\\n\";"</code> Anyway if it is parsed doesn't mean it will make any difference in the system performance at all.
