OSX 10.10.1 with FileVault2 on doesn't boot with launchd CODE SIGNING error

First of all, I want to clarify my intentions: I'm not asking about how to make this mac work again, I do know about Recovery HD and other methods of recovering. I want to know what does the error mean and if there a way of fixing it manually for educational purposes.

Mac OS Yosemite (10.10.1) with FileVault2 does not boot with the following error:

CODE SIGNING: cs_invalid_page(0x7ffff719b1000): p=1[launchd] final status 0x20000000, allowing (remove VALID) page

I've tried to google it, but failed. What does the error mean?

I've checked everything about this /sbin/launchd: size, crc, modification date are the same with the bootable 10.10.1 FV2 system, codesign -vvvv says everything is ok.

Please advice.

cooling case for overheating iphone? looking for info about this

if anyone knows more info about this i would love to know. so far i couldn't find anything much online. suppose to be a new case for phones ? called "optimal" ? saw that on Facebook.

Why is my iPhone 5S overheating so much?

Activities such as:

1. Phone Calls that last around 10 minutes


2. 3G Browsing for 5 - 7 minutes


3. Watching videos for 5 minutes


4. Using apps such as facebook / instagram etc for 5 - 7 minutes, lead to my iPhone 5S severely overheating.

It heats so much at times that it can't be held any more and you have to set it down for it to cool down.

At times, it randomly restarts when plugged in. When it starts to heat the battery drops sharply and sometimes the phone simply dies

I'm fairly certain that the hardware in my phone is being affected with this overheating

My first year phone warranty ends in 10 days and I'm contemplating whether I should give it to Apple India Service and if they will replace my phone.

Any Solutions? Suggestions? Experiences with Indian Apple Service Centres?

What is the xpcd executable / Darwin xpc(3) service

The first item in the search results for dialog com.apple.internetaccounts.xpc is http://ift.tt/1rKy84i, which complains that "[e]very 10-15 minutes the following prompt pops up on the screen" (img-1), and is how I learned of the Darwin XPC service.

The documentation I have so far (from an up-to-date Mavericks machine):

1. The Darwin xpc(3) manpage, which names 12 other man pages, of which none are 'xpcd' and one does not actually have a man page (i.e. man 3 xpc_abort gives an error). (You apparently need Xcode for man 3 xpc to give you the page at your CLI;)


2. ActivityMonitor.app shows three PIDs named 'xpcd', which I think is probably part of the XPC service. The three PIDs are run with UIDs 'root', '_security' and whoami;


3. No results for man xpcd


4. 
   

   mdfind xpcd gives:

   
   

   
   helen:~ stewart$ mdfind xpcd
   /System/Library/Sandbox/Profiles/com.apple.xpcd.sb
   /System/Library/LaunchDaemons/com.apple.xpcd.plist
   /usr/libexec/xpcd
   
   

I want to know more about this service, in particular, I want to know:

1. What command-line arguments does /usr/libexec/xpcd take?


2. How do I determine what the XPC service is doing? When does it ask for items from the Keychain?


3. Is xpcd properly documented anywhere?

(img-1): The image link from that discussions.apple.com discussion page is broken, but presumably the same as twitter-dialog-xpc.png:

Will a Microsoft Office Add-In developed in Visual Studio work for both a Windows and Mac ( osx ) versions of Ms Office?

I want to develop a Microsoft Office Word Add-In for Mac Users. I would like to know if we create it using Visual Studios in windows will it be compatible with the Mac version of office or is there a whole another way to develop for Mac?

Please provide links so that I could follow some guidelines. The http://ift.tt/rnTyPu site doesn't exactly speak of the platform compatibility of the Add-In.

Thank You very Much in Advance.

How to set a custom icon inside a signed Apple Script application?

I'm using Apple Script to distribute a signed applet, and would like to use a custom icon. However, as soon as I export it from Script Editor, the bundle loses the custom applet.icns file I put in it. It's reverted to the standard script icon (see screenshot).

How do I export my script as an app without losing my custom icon?

If not possible: are there other ways to sign an Apple Script application bundle on OS X 10.10? This would allow me to do a manual icon replacement and sign the bundle afterwards.

Important twist: Replacing the applet.icns file afterwards is not an option, as the bundle won't pass signature validation anymore. In short, users get a damaged app error when launching the app, unless they have lowered their OS X security.
