Startup gets stuck at "no" icon after enabling filevault
I have a clean install of 10.7 on a 2010 MBP (reinitialized HD, installed snow leopard, installed Lion).
After enabling File Vault, it asked me to retart my Mac. I did that, logged into the account I provided file vault access to, and now have been stuck for hours at a screen that just shows the "no" icon (circle with a diagonal line through it) with the spinning progress wheel underneath it.
I let it do this overnight and then restarted the Mac this morning, logged in again, and I'm back at the same screen.
I have a full backup and can restore from that if necessary, but my bigger issue is how can I get filevault to successfully work on my Mac.
Any suggestions greatly appreciated.
Update based on some additional troubleshooting:
I've now been able to recreate this three times by following this sequence (I've started to restart more frequently to pinpoint where things go wrong)
Reformat Mac partition (leaving Boot Camp alone)
Install OSX 10.6.3 using the install disc that came with my computer
Run software update until all updates applied (requiring a few restarts)
Install Lion
Restore applications and my local user directory using Migration Assistant and my Time Machine backup
So far so good.
6. Restore "other settings" (I believe it's called that) in Migration Assistant.
This is when the issue first appears. Not sure what setting would cause this issue, but whatever it is, it effectively makes my Mac HD unreadable.

Macbook doesnt startup, gets stuck at blue screen after langauges deleted
Hi,
Got a mackbook pro running Snow Leapard. I was trying to clean up some space by deleting some language files using monolingual. It started deleting english so i cancelled, and when i restarted it has the grey screen with the apple logo then goes to blue with nothing..
Checking on the net it seems to be the font files. I dont want to just 'reinstall the os'. Surely i can replace the system fonts.
How can i do so?Easy, read the

4s won't reboot after ios7 update. I have restored 4 times. Every time it gets stuck on Apple icon with update bar at 10%
HELP!That's one of the weird things.. it recognizes it maybe 10% of the time. And usually, only after I do the two-button reset. Problem is.. since it won't charge above 2%, anytime I try to do a restore or anything like that using iTunes, my device shuts off and I lose whatever progress I'd made.
So, an update... after reading through a bunch of similar complaints (there are literally 1000's of them so there's NO WAY this isn't somehow ios7 related, thanks a lot APPLE ) I decided to try a restore in recovery mode. After 3 hours and several disconnections... I ended up having to just set it up as a new iPad, as the restore did nothing. Weirdly though... as I was doing the restore in recovery mode.. I noticed I'd gotten up to a 10% charge.. higher than it's been since September, so after setting it up as a new device, I turned it off and plugged it in using the wall charger. 2 hours later and I was up to 38%. Still not great, as my iPad, before ios7 could've fully charged twice in the amount of time it took for me to now get 28% more of a charge. And that's with a fully cleaned out device.. so that really ***** and I'm now more confused than ever.
But I'm gonna leave it overnight charging and see what I come up with tomorrow. Sadly, when I paid $600 for it in February, I never expected to have to play "wait and see" with it... -

IMac startup gets stuck on grey screen
This is an intermittent issue and has only been happening for the last week or so. When I start up my iMac (bought early 2008, running Snow Leopard and fully updated) it will get stuck on the grey screen before the apple logo appears.
I have to hold the power button for a few seconds to shut everything down completely and turn it back on. Second time round it seems to power up fine (so far) so I'm a bit bemused as to what the issue is. I keep my external HD plugged in, so that's always connected when I boot up, but that hasn't been an issue before...
I've been having the issue since I bought my iMac back to uni. I'm always careful to package it properly (back in its original box) but I guess maybe it got clunked in the car? I don't know whether that would have an impact or not. I'm also careful to keep around 100Gb free on my HD to keep it running smoothly.
Any ideas would be hugely appreciated, as final year of uni is not a great time for my Mac to break!OK, yes 100GB out of 320GB is plenty of space, the rule of thumb on Macs is you should have 10-15% of HD space available.
Regarding your power, that's a possible cause. If it does prove to be the problem I would recommend investing in a battery backup to ensure your iMac is not only is getting consistent power but is protected in the event of power failures or power spikes.
There are some things you can check, although they aren't 100% definitive they can give some clues. First is open Disk Utility (Applications-Utilities-Disk Utility) and check the S.M.A.R.T. status of your internal HD. It should say Verified, if it doesn't it's definitely in trouble and either needs repairing or replacing. You can also run Repair Disk Permissions in Disk Utility. Both actions should take less than 10 minutes on your machine. -
Macbook pro does not boot after enabling Filevault
macbook pro with OS 10.9.2 : after enabling encryption ran in to a problem and did not startup.
did the followings:
- loaded to recovery mode: command-R
- disk utility- verify disk> repair disk
- tried to reinstall OS : did not work
- re-partitioned the hard drive
- tried to install it from bootable Mac os installation : it worked but after running the software update it did not start up again....
- sent the mac to repair store to replace the hard drive with SSD hard : they setup the hard with mac os 10.9.5
- installed all the software update
- enabled the file-vault " this time it finished the encryption but when started up and tried to login with user account it got frozen and did not work and so on ...
- again tried to go to recovery mod and repair the hard and reinstall OS but it did not install the OS
- had to again repartition the hard ...
PS: the macbook loads fine with the OS on External hard disk .
this is really frustrating, can somebody tell me what's wrong with this mac why this issue happens after enabling encryption and why the issue is not gone even after reformatting the partition...I finally fixed the issue myself
The macbook had a RAM issue: Replaced the RAM and it is fine now. -
Cannot access recovery partition after enabling filevault
I did a clean install of Lion by extracting the disk image to an external Firewire drive, using disk utility to reparition my Macbook Pro's internal drive to a single, blank HFS+ parition, and then installed Lion to that partition from the external firewire drive. It worked flawlessly. At that point, without the firewire drive plugged in, I could boot to Lion, and if I held option while starting the computer, I could also see the recovery parition as an option to boot into.
After that, I used Bootcamp to install Windows, which resized my Lion partition. After that, I enabled FileVault. Everything went resonabley well: The Lion partition is now encrypted, and Windows still works, and the computer is functioning, however when holding option at boot, the only options I see are Lion and Windows. The Recovery boot option is no longer visible. I don't know if it was the act of using Bootcamp, or Filevault (or the combination of both) that caused it to dissapear, but I changed nothing else that I can think of.
I'm resonabley certain the actual recovery partition is still there. The diskutil list command outputs the following:
Lownins-MacBook-Pro:~ Lownin$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *320.1 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_CoreStorage 259.0 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Microsoft Basic Data Windows 60.2 GB disk0s4
My question is: How do I re-enable the Apple_Boot Recovery partition as a boot option from the "option key while booting" menu?OS X Lion: About FileVault 2

Rebel T2i Gets Stuck in "BUSY" Mode After Recording a Video
Hey! I've been recording video on my T2i for a while but suddenly, after recording a video, the camera would freeze in busy mode and then eventually shut off. I made a video explaing what is happening:
If anybody knows what I can do to fix this then please let me know.The camera powering off on you is the firmware crashing.
The on/off switch is really just a "software" switch. It does not actually deprive power. This is sort of like a TV and remote control... in that when you "turn off" a TV it's not *really* off... the screen is off and it's gone to 'sleep' but some part of it is technically 'on' and monitoring for a signal from your remote control. The same is true of the camera and the power swtich... it's actually in a kind of extended 'sleep' mode.
When you open the battery door (or even eject the battery) there's a micro-switch that cuts off power. That actually DOES turn the camera off (really 'off' because the camera has been deprived of all electricity.) Inserting the battery and closing the door causes the camera to 'boot' fresh again... so the power switch (and everything else) will actually be monitored and respond as intended.
So what's wrong? PROBABLY the memory card. In nearly all of these cases with the stuck 'busy' problem it means the camera is trying to write your video clip to the card and for whatever reason it is not successful.
I did notice you're using a SanDisk Ultra card (good). How old is the card?
A few tips:
ALWAYS format the card IN CAMERA (if you formatted a card while it was in your computer, then re-format it using the camera and pick the "low level" checkbox when you format it.)
I do suggest you perform a new in-camera format and make sure you check the "low level" option.
Memory cards do not last forever. It's also possible you've got a dud (nothing is 100%). The process of "writing" to a memory card is technically physically destructive (just a tiny bit) to the card. Reading is non-destructive... you can 'read' from a card millions of times and never wear it out, but each time you 'write' to the card and change the charge state in a memory location you will have ever-so-slightly caused 'wear' to that location. The card will eventually fail (all cards will). But for most cards you'll get something like 100,000 writes before it becomes a problem (years of heavy use). BUT... if you got unlucky and had a weak card, your card may be showing early signs of failure. It happens.
I ALWAYS suggest you own more than one card (I have lots of them) and test with a different card. If this is the only card you own, then you need to buy another card anyway because you never want to be caught without a spare card on-hand for just such an emergency.
Next... there are forgery cards on the market and some of them are amazingly good forgeries. What separates your really nice SanDisk Ultra card from all the non-name unlabled "junk" grade cards ... is that your card has a really nice sticker on it. It's not too difficult for a counterfeiter to print up a pretty convincing looking sticker. I and several others here will tell you that it's not just enough that you bought a top-name memory card... you ALSO need to buy that card from a known reputable dealer to make sure you're not buying a forgery card. Stated differently... I am unwilling to buy a memory card from a merchant I've never heard of before because they sell the same card I can get from a well-known merchant for $5 less. Screw the $5... I want "known" quanity and that's worth far more than $5 to me.
This is not to say that YOUR specific card is a forgery... even SanDisk will just occasionally ship out a card that passed they're quality test after being manufactured... but just barely. You get it and start using it heavily and the next thing you know it's showing signs of failure.
Could it be your camera? Sure... it's just unlikely.
Occam's Razor (a well-established guideline for critical thinking using the scientific method) states that among competing hypotheses, whichever one requires the fewest assumptions should be selected.
In your case the competing hypotheses are:
1) The camera is failing: Except that the camera doesn't fail at any other task... just this one particular task. That's a bit difficult to explain.
2) The memory card is failing: We've actually got well-established and well-understood failure of memory cards (a memory technology which will by it's very design WILL eventually fail.) We don't need to apply many assumptions here.
As I mentioned above... you need another memory card anyway (every camera owner should have at least 2). You may as well just start with that.
Good luck!

MacBook Pro mid 2013 13' gets stuck on White screen after login.
I'm in safe mode right now. I Booted it up in Safe Mode by holding down the shift key during startup. What do I do now to not get the white/grey screen during startup after login?
Mac OS X: Gray screen appears during startup
If the grey screen occurs when you boot normally (not safe mode) try bypassing your Login Items by holding a Shift key in the same manner during login (i.e. not during boot). If you can log in, you effectively isolated the problem to one of more of your Login Items. -
Ipod touch is stuck on swirly icon after lock screen freezing
My ipod got stuck on the lock screen and wouldn't respond to anything I tried. Left it for 10 minutes and came back and it had gone to the swirly icon screen which normally comes after updating your ipod. It has been on this swirly icon screen for about 30 minutes now. Tried syncing with itunes no response, also restarting using lock and home button does not work. Will not turn off either. I'm going to restore ipod now but it takes 4 hours for the software to update is this right??
Thank you.Yes, someties it can take hours for the update. The download can take hours.
If you can't restore the iPod since iTunes will not see the iPod, disconnect he iPod from a charging source and let the battery full drain. After charging for an hour try the reset, and restore. You also may have to place the iPod in recovery mode. For that see:

How to get rid of update icon after updating apps
So, since updating to iOS 7, I've noticed that any apps I update now show a small round blue icon next to the app name.
I get that this is supposed to let us know which apps have been updated, but is there any way to get rid of them all at once?
So far all I've seen is that you have to open each updated app one at a time to get rid of it.
Thanks in advance.There is no way of doing that

Problem #2 Upon startup get flashing Google map icon then ? finally starts
In further review and work towards external hard drive (startup disc) near full,
I have encounterd upon startup a flashing icon which I believe is google world or map icon. This flashes for about 30 seconds, and then turns into a flashing ?? with a Mac type face/file. The google map or world app does not appear to be anywhere that I can find on the computer. Any advice on how to make right?
Also how can users download stuff like this without admin privileges.
Thanks Jim SvarzHi Again Jim Svarz!
In System Preferences > Startup Disks, what should be selected is Mac OS X 10.3.7 on Macintosh HD.
If that corrects the issue, what you were seeing wasn't a symptom of something that was downloaded. The system was just searching for a drive to start up from.
