After update to 10.7.1 /var/db/BootCache.playlist is deleted

I have reloaded Lion server at least a dozen times and it keeps happening after I update to 10.7.1 /var/db/BootCache.playlist gets deleted. I dont know ifs its something I am doing wrong when setting up my server but this is getting crazy. I only host a website and use as email server for that website. Does anyone think it might be, I set up the Server HD as a sharepoint? This is the only thing I can think of? Has anyone else had this problem? I also change the greylisting feature using Terminal but I am changing no files near /var/db/. Any ideas cause 12 times of setting up a server is making me mad? Thanks!

solved my problem. looks like the file is there just not accessible?
got on the phone with Apple and did the following:
- booted to Restore disk (Command + R on boot) and ran Repair Disk and Repair Permissions through Disk Utility (on the server OS HDD).
- then went Apple --> Select Boot Disk --> Selected the server HDD --> Restart
after this i was able to boot up normally, but the Firmware update hadn't applied. before doing any more software updates i made a clone of my server on an external HDD using Disk Utility --> select server OS HDD --> Restore tab --> Destination: External HDD (note, you'll lose anything on the external drive)
after getting the clone i did the firmware update without a hitch.
unrelated to this, the fan on my Mac Mini was going full blast all the time. the fix was to pull out all the cords and let it rest for 30 seconds, then plug everything back in.
hope this helps someone.

/var/db/BootCaches.playlist 2:no such file or directory appeared after Mavericks update

Hi all,
I have tried to upgrade my iMac 2009 running 10.6.8, 3.06GHZ, 4GB ram machine and hit upon a grey load up screen and nothing more after the update. I have worked back through everything I could find in these forums as the bellow:
1. Completed all of the grey screen advice from Apple bar a full wipe and rebuild, but have left this as the last resort
2. Launched again from back up and reloaded Mavericks only to get the same problem
3. Tried to launch in Safe mode and the computer quits half way through the status bar and will not launch into Safe mode
4. Corrected all disk permissions in Disk Utility
5. Checked my EFI update and am running the latest version
6. Tried resetting the NVRAM but computer will not work from the keyboard shortcuts
7. Run Verbose mode where I could see the problem with loading Bootcache which produces the following script /var/db/BootCaches.playlist 2:no such file or directory
8. Created a carbon copy backup also and am now considering a full wipe
I have updated to Mac Book Airs in the last few weeks, and after the computer auto restarts the program then moves to a new processing screen where it finalises writing script, this point never happened on my iMac and after it restarted it just hung on the grey screen with the Apple logo. It is definitely in the Bootcache problem as this is one of te last processes and matches the amount of time the computer starts working before it heads into the grey hanging screen of death. This is definitely something that mavericks script alters, moves or deletes as I have seen this problem littered across the forums as well as the in ability for Safe mode now to work.
I am back up and running 10.6.8 at current and downloading a new version of Mavericks (more fool me). It could be a drive corruption but am unsure, but the computer s working well on 10.6.8 and has done for a very long time. Has anyone solved this yet, as t s driving me crazy!!!
Any Jedi's out there, I would be most indebted to you!

Hi all,
Well I thought I would re-post as have found a solution.
I created a bootable USB version of Mavericks using this article here which was very informative: http://www.techrepublic.com/blog/apple-in-the-enterprise/how-to-create-a-bootabl e-usb-to-install-os-x-mavericks/
I then rebooted via it, this again caused the grey screen of death as I thought it would, from reboot to reach this screen I held the Option Button. Before I did this I took a cloned copy of the hard drive and also backed-up again to Time Machine. Have over 470GB of music, photos and films, so yes was being a little over precautious.
I then rebooted and went into recovery mode (Cmd and R) and erased my hard drive.
I then rebooted once again but booted from my Mavericks USB version now with a clean hard drive, and set-up completed as expected with no problems. Its working beautifully at current but am yet to migrate files using the migration assistant, but once I have the new Mavericks version of my machine backed-up I will complete the migration, fingers crossed!
A few days of pain, but was a good learning experience. It was more difficult than it should be to created a bootable USB, but luckily I had another mac to work on and a decent back-up drive.
Hopefully helpful to others!

My battery life decreased dramatically after updating to ios 6.1.2. How do I delete and go back to previous iso?

I have iphone 5; my battery life decreased dramatically after updating to ios 6.1.2. How do I delete and go back to previous iso?

Downgrading the iOS isn't supported and wouldn't help even if you could. There have been reports of decreased battery life after every update since iOS 1.0.1.
There are lots of things that can be done including reinstalling push email accounts. basic phone reset (pressing both home and power buttons for at least 10 seconds until the Apple logo appears), and restoring the phone with and without a backup.

TS2570 Still cant access my computer, followed instructions to perform a safe boot and last line of script it shows: BootCacheControl: Unable to open /Var/db/BootCache.playlist:2 No such file or directory. Any idea?

Brand new Mac Book Pro
Purchased in Mexico's Department store Liverpool on June 20th 2012
Purchased Memory upgade to 8Gb, on june 27th, at Apple Store Memorial City, Houston
Upgraded memory from 4Gb to 8Gb on June 28th.
Tried to write on my external HD (previously written on a windows based PC) with no success.
Upon reccomendation from a Mac assistant, copied all my external HD contents into my Mac Hard drive.
Then formatted my external HD and copied back all my information to it.
deleted all the information from my MacBook Pro HD.
Attempted to repeat the same operation with another external HD, but got a message saying there was not enough epace on the computer HD (even though I have a 750Gb Hard Drive.
Looked in the trash bin and there it was, all the information previously deleted..
Could not empty the trash bin, although I got a message asking me to safely delete all the information from the trash bin,
Could not get enough space released, after several attpempts the trash bin was finally emptied.
All happy getting acquainted with my new MacBook Pro. Two days later, got a gray screen and not able to start the computer.
Looking in to Mac support I found article http://support.apple.com/kb/TS2570 and followed instructions to perform a safe boot:
"Perform a Safe Boot
Simply performing the Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to
see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
The following is the script that appears on the screen upon safe boot. and halt after the last line.

Help! /var/db/BootCaches.playlist 2:no such file or directory appeared; unable to start up

I use a MacBook Pro, Mid-2009 version.
My problem started when I tried tweaking some system files via Terminal when I could no longer use Candy Bar for Mavericks. I followed the instructions here http://idevicedailys.com/os-x/howto-use-candybar-os-x-mavericks/ I was quite successful but not all of my icons changed so I downloaded the 10.9 patch for Candybar. The fix did not work, so I tried using the sudo nano /System/Library/CoreServices/SystemVersion.plist command again. Afterwards, I tried opening Candybar, but it would no longer open. I then restarted my Macbook, but it would no longer load into the desktop. What happens is that after loading, the cursor would show up, the screen would blink, and then the loading icon (the gray rotating thing) would show up again, and then the cursor appears. This happens again and again. At some point, the loading icon would just freeze.
I tried rebooting to safe mode, but it will not work. /var/db/BootCaches.playlist 2 cannot be found I tried accessing Terminal through the Startup Disk screen (the one you get to when you press cmd + r during reboot) but the sudo nano commands won't work anymore. Also, instead of nano, what I see in my Terminal is 'bash'
Is there still hope for my mac?
Help is very much appreciated!

Do a backup. Boot to the Recovery Volume (command - R on a restart or hold down the option key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then reinstall the OS.

Boot into Recovery (command-R at startup), launch Disk Utility, select your startup volume, and run Repair Permissions. Then reboot as usual.

Could not open ... could not unlink ... /var/db/BootCache.playlist

In 10.5.7, on my QS 2002 Dual 1GHz, I keep getting this message.
Awhile ago, someone suggested I Trash this file
/var/db/BootCache.playlist,
thinking it would be regenerated next Startup.
Is there a Terminal command that I can use to accomplish this? Something that would signle my OS X, to regenerate this file next go 'round?
Here are the log entries I find troubling:

I see this in a number of other threads, but have not located a solution.
Thanks.

After an "event" on my computer, all of my playlists were deleted. All of my music is still there, but I am concerned about synching my idpod, as many hundreds of hours were involved in creating the playlists and I do not want to lose them. Suggestions?

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

HT201210 After updating to IOS 6 I no longer had playlist in music, I turned on Match and now I have 2 of every playlist

after updating to IOS 6, I went out to mow my yard and listen to my music via bluetooth headset as I have done all summer. But to my surprise there was no longer a playlist not one!!!!!   so after mowing and listening to one album I tried turning on Match and now I have 2 of every playlist.
I realize that there will be a few glitches when upgrading a new system. I would like to see Apple come up with a simple way to contact Apple to let them know about these new problems. This is only one of them and there are a few more on the iphone and even more on the newest ipad.
for instance I buy 64gb iphones and ipads, because I do not want to stream my photos or music I do not always have access to wifi or cellular. Plus with over 5,000 songs and 15,000 photos it takes to long so I want to store them and us sync to save changes. I have a very advanced setup. with outdoor entertainment around the pool "covered" in the party room, in the house, in the RV outside the RV. The list goes on. I want my picturesand music stored!!!! not all Streamed. when ever we try to stream pictures or music for one of my parties there are freezes and hangups. Not something I like when I have 60- 100 friends over. Storeing all this to a device should be easy when I USB it to my IMAC!!!! also when I take pictures around my party and then the Apple TV fails to keep up streaming I plug the iphone into a source to the stereo's and the **** thing starts sending all my photo stream through the wifi to the computer and now it will not play music or photos until it is finished.   Here I go again with all these guest saying I thought you said apple was better!!!!! we need to be able to select when we want sync to happen to prevent this with out turning off icoud or phot stream.

I am back with an update. I turned off Match on both the ipad and the iphone 5. By doing so I was able to sync my Iphone and ipad to itunes and store the music on my devices rather than the slow streaming. So far this has fixed my problems with the iphone I have all my music, playlist, most of the album art and so on. But the ipad is a different story. I have the music and artist but not one playlist I am sure Apple will have an upgrade soon that will address these issues they are usually very good about this.
Now have any of you experienced another problem that has existed as long as I have used faces in Aperture.
I have over 200 faces and they are organized a-z problem is I have this going on A-Z folowed by a few that start over A-Z followed by another few A-Z and again a 4th time A-Z. Imagine how difficult it is while I am showing someone the great features of my iphone, ipad and imac. Which I do talk highly of all the time. But how do I explain that even though their name starts with a or b or what ever they are not important enough to me to be in the first list of A-Z or even the 2nd or 3rd list of A-Z someohow they are in the 4th section of the list!!!!
I have managed to get the Imac to fix this but for some reason the IOS devices do not.   Any ideas?
Thanks Al

After updating to iTunes 7, can't find "purchased" playlist in Front Row

After updating to iTunes 7 (and QT 7), I discovered that Apple has moved the "purchased" list of music to the "store" section. Therefore, I cannot access my "purchased" list from Front Row. Does anyone know how to fix this? My primary use for Front Row was to play my "purchased" playlist from a distance.
I thought about creating a playlist called "purchased" but that seemed messy since there would be two of them in the sidebar. I also considered reconfiguring Front Row, but don't know how to do that.
I don't NEED to be able to do this because I can browse my purchased songs in other menus, such as "Library" or "Recently Added." But, I really like browsing my purchased songs separately from my other songs.
Before upgrading to iTunes 7, Front Row allowed me to do this, but not after the upgrade. Now, iTunes has removed "Purchased" music from the Playlist menu, and placed it next to the iTunes Store.
Is there a way to reconfigure Front Row so that "Purchased" is included as one of the song menus I can browse?
17" iMac Mac OS X (10.4.7) 1.83 Intel Core Duo, 160gb, 512mb

Although I appreciate the empathy, I think we're having different problems. I have no problem playing the songs I've purchased from iTunes, but Front Row doesn't allow me to select the "Purchased" playlist. I can do this in iTunes, but not in Front Row.

ITunes deleted my play counts after update. How do I get them back?, iTunes deleted my play counts after update. How do I get them back?

Hi yesterday I updated iTunes to the most recent version. After I had restarted my computer all my play counts had gone. Can I get them back?

Me to on my ip5. Then i noticed all accounts were gone in mail.
Luckily i had 90% backed up in yahoo so when i set up the account again i had most back. Still sure though info is missing.
In icloud i only found about 10 contacts who had been stored in icloud contacts
Any way i can get all data back? Can't be i accidentaly deleted these accounts right before download of ios 7

After updating to iCloud and setting up iCal sync the program deleted all my Outlook events and cleared them from my office's server. How do I now sync my still existing iCal events back to Outlook for syncing with my office.

How can I get my Outlook information that was moved to iCal back onto my Outlook calendar for syncing with my office's exchange service?

Problem solved I think. I exported my iCloud Calendar file in Outlook to Google Calendar which in turned re-populated my Outlook default calendar. This was picked up by the exchange and sent to all computers in the office.
I had hoped that iCloud, and its calendaring abilities, would remove my need for Google calendar to serve as an exchange between my iPad, iPhone and Outlook on PC (and with it connection to my staff). However, it seems that iCloud is simply not to that point yet. Hopefully Apple will begin to implement some of the processes Google Sync utilizies, specifically the ability for Sync to keep a PC running Outlook and an Android based phone in near-real-time sync. It seems that as of yet Apple has not considered the cross-platform issues of the iPhone being in wide-use in business/commercial settings with PCs running Outlook (and said PC being networked to staff, coworkers, etc...).

After update to 10.7.1 /var/db/BootCache.playlist is deleted
