Hackintosh 4540s – Mountain Lion update sound problems

Apple issued an update to Mountain Lion 10.8.4 this week which I applied via system update. This left my hackintosh probook 4540s without sound and also removed the battery status indicator from the menu bar.

After a bit of investigation I found this was easily fixed by re-running the Probook installer from the tonymac site. I downloaded the latest version, since there had been several updates since I did my initial install a few weeks ago, and was initially confused because I couldn’t find anything in the various options which referenced audio. After several attempts I found that the option to run is the option “OS X Support Kexts -> 4x40s -> Mountain Lion -> 10.8.3”. This was not obvious because I’m actually running 10.8.4, but it works and after a reboot the audio / battery indicator is now back and running properly.


I’m a software developer by profession but I’ve been taking pictures since I was about 8 years old. In that time I’ve owned cameras of all types and sizes from 120 roll film thro’ 35mm to my current Pentax K-5, Ricoh GXR + P10/S10/A12 28mm/A12 50mm, Canon S95 and recently acquired Sony NEX 6.

    Hi Simon, thanks for the informative write-ups. I’ve just put El Capitan on a Probook 4540s i3, and it’s mostly working. I’ve still no sound though, and the Probook Installer has been retired, so I’m a little nervous about running any of the available versions. Have you upgraded your 4540s to El Capitan (or Sierra) yet? – thanks Chris

      Hi Chris – I upgraded it to Yosemite using the guide at tonymac ( I had
      fitted a new hard drive in place to the cd drive so I did a new fresh install and it actually went better than the original install with the sleep function all working and the SD card reader (which used to cause a hard crash on the previous version). Apparently, I should be able to upgrade by using the upgrade options that the store offers but I haven’t done that because Yosemite works well and I don’t want to risk breaking it!

        thanks Simon. I’m also nervous about breaking my mostly-functioning El Capitan installation. I’ve just loaded Logic Pro X onto it an it all seems to work! I’ll try fixing the sound soon, but I’ll probably use an external audio interface if I can’t get around it.
