Application crash on Startup

This posting is older than 6 months and can contain outdated information.

Hello Felix,

I get this kextcache error every time I restart my mac. Would you be able to tell me if they are because of Remote Buddy?

Thanks in advance!

Hardware - Apple® Remote

After uninstalling/quitting Remote Buddy, my Mac® no longer reacts to the Apple® Remote. (FAQ015E0241)
To enable you to use all capabilities of the IR Receiver of your Mac®, Remote Buddy is using its own driver. In contrast, all other applications with integrated Apple® Remote support usually use the OS X Apple® Remote subsystem.

As long as you're running Remote Buddy, Remote Buddy and its driver are responsible for turning the received button presses into actions. As soon as you quit Remote Buddy, this task is again handled by the OS X Apple® Remote subsystem.

If other applications don't use the interface to the OS X Apple® Remote subsystem correctly, this can lead to the effect that nothing happens when you press a button on your Apple® Remote. For as long as you're running Remote Buddy, issues like this are covered by Remote Buddy and it's driver and are therefore not visible to you. However, as soon as you quit Remote Buddy, the OS X Apple® Remote subsystem is back in control and any issues caused in it by other applications become visible.

Therefore Remote Buddy is neither the cause of the issue nor is it responsible for it. Instead, the cause of the issue exists independently of Remote Buddy. It's located elsewhere and can also only be solved there.

Although our products can't cause any such issues, we're regularly contacted about such issues and asked for help. In order to make locating and fixing the cause of such issues as easy and efficient as possible, we've developed a free diagnostics tool: Remote Control Diagnostics. It can locate issues with a single click and will provide you with information about the issue as well as with instructions on how you can fix it.
After updating to OS X 10.6.2, my Apple® Remote is no longer available for selection in Remote Buddy. (FAQ015E0236)
Please update your copy of Remote Buddy to version 1.15 or later.

Hardware - Sony® BD Remote Control

I'm having problems with the Sony® PS3 BD Remote under OS X® 10.8/10.9. (FAQ015E0246)
There's a bug in the Bluetooth®-stack of OS X® 10.8/10.9 in the context of pairing a Sony® PS3 BD Remote. OS X® 10.8/10.9 will ask you to enter a PIN code when you try to connect your remote control. This problem is known by Apple®.

If you pair your Sony® PS3 BD Remote with your Mac® for the first time
1. Use Remote Buddy's Setup Wizard to pair your remote control
2. Restart your Mac® directly after the pairing was successful, while the remote is still connected.
3. The remote should now work without problems.
If you've already paired the Sony® PS3 BD Remote with your Mac®
1. 10.9 only: Try entering 0000 as PIN and reboot. If you're lucky, that was all you needed to do. If this does not solve your issue, please continue with the steps that follow.
2. First, we'll need to remove the Link Key of your Mac® from the memory of your remote control. Since this remote control can only store one Link Key, it's as easy as pairing the remote control with another Mac®. To do so, open System Preferences > Bluetooth on another Mac® and pair your remote with it.
3. All steps that follow should be performed on the Mac® that you want to use your remote control with.
4. Remove - if it exists - the entry of your remote control at Remote Buddy > Preferences > Hardware ® Bluetooth Receiver. The entry usually is titled "BD Remote".
5. If existant, remove the device "BD Remote" from System Preferences > Bluetooth.
6. Delete the Bluetooth preferences files by entering the following in Terminal.app and hitting return (Warning: this deletes all information about all paired Bluetooth® devices):
```
sudo rm /Library/Preferences/com.apple.Bluetooth.plist
sudo rm ~/Library/Preferences/com.apple.Bluetooth.plist
sudo rm ~/Library/Preferences/ByHost/com.apple.Bluetooth.*.plist
```
  Please enter your admin password when requested. Then restart your Mac®.
7. Use Remote Buddy's Setup Wizard to pair your remote control
8. Restart your Mac® directly after the pairing was successful, while the remote is still connected.
9. The remote should now work without problems.

Hardware - Wii™ Remote

How can I activate the Bluetooth® receiver automatically on startup? (FAQ015E0163)
In order to automatically activate the Bluetooth® Receiver on startup, enter the settings, choose "Hardware", then click on "Bluetooth® Receiver". Finally activate the checkbox "Search for supported remotes on startup". Remote Buddy will then automatically look for remote control paired through the "Setup Wizard" on next startup.

Hello Matthew,

thanks for asking.

The crash log does not describe a kernel panic, but a crash of the
application kextcache, which runs in user space. (I've changed the
topic of this thread to reflect that)

- Remote Buddy is not running at this point

- the kernel extension does not do *anything* until after Remote Buddy
is loaded and running

- the kernel extension does neither hack, patch, modify, replace,
remove or otherwise alter any of your kernel extensions, functions or
system files (it is *completely* system conform, using only documented
APIs in an absolutely clean manner).

- Remote Buddy is not invoking kextcache at all (not even in its
installer), following the advise in the kextcache man page

- and kextcache works *on* kernel extension files, but does neither
load nor execute any code contained in them

neither Remote Buddy nor its kernel extension can be the cause of that
tool's crash, sorry.

Also, googling for "kextcache crash" and "kextcache crash patchVTable"
will lead you to a handful of similiar or even identical crash logs -
some of which are predating even the first line of code of Remote
Buddy by a year.

Best regards,
Felix

Thank you very much for the quick reply Felix. I will try calling Apple Tech Support. It seemed to happen just as Remote Buddy started so I thought I would ask.

No need to keep the topic here, so delete it if you want.

The search for "kextcache crash patchVTable" turned up a post in the apple discussions that I replied to. haha.
