SOS! My MacAir could not be turn on after I erase the hard drive memories

After I erase the hard drive memories, the MacAir could not be turn on. When I turn it on, there is a question mark show in the screen n then nothing. What should I do now?

After I erase the hard drive memories, the MacAir could not be turn on.
With no OS to startup to, that would be the expected result.
Restart and hold down the Command+R keys to startup into Recovery Mode. Reinstall the OS.
If that doesn't work (you erased literally the whole drive), restart and hold down Command+Option+R to launch Internet Recovery Mode. The entire OS for your model Mac will be reinstalled.
You will need an Internet connection for either OS installation.

HT201250 I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them?

I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them? No, they were not part of previous Time Machine backups, and I have checked both the hard drive the documents were lost on and the new one that I now use for backups. Any suggestions would be helpful, as the lost files are old pictures that are gone forever. :[ Thanks!

1. Yes, if both drives are formatted as Mac OS Extended (Journaled).
2. Reformat the drives if needed, open the Time Machine pane of System Preferences, and remove the drive with the pictures from the list of items set to be excluded.

HT201071 RAW does not work in Mavericks after disk utility repaired hard drive

This worked until I had to repair a corrupted section of the hard drive, now Nikon Camera RAW files do not work for Aperture, Photoshop or even viewing in the finder. Is there a way to download just the RAW file compatability?

The latest download I could find is Digital Camera RAW Compatibility Update 5.04. Others are linked from this Apple - Support - Search. Or consider OS X Mavericks: Reinstall OS X to get all the latest software in one step.
(If you haven't already done so, set your OS X Mavericks: App Store preferences to automatically check for updates so your Mac will advise you when future Apple updates like these become available.)

I am trying to retrieve folders- they do not appear in Thunderbird, but are on the hard drive.

1. I have used Thunderbird for 5 years or so, using at least 3 mail addresses at a time. I stow useful mails in folders and subfolders for reference. I regularly use Mozbackup.
2. Recently I found that one of the main folders was missing, a search of the hard drive revealed that the.msf folders are there, but I dont know how to restore them.
3. In an effort to retrieve them from a Mozbackup file, i found that email addresses 1,2 and 3 were available.
This was not useful as email addresses 2 and 3 had been replaced by email addresses 4 and 5 3 years ago. (Mozbackup issue)
4. Thus I now have only folders from email 1 and all other from emails 4 and 5 have gone.
Would be grateful for any help

re: 2.'' Recently I found that one of the main folders was missing, a search of the hard drive revealed that the.msf folders are there, but I dont know how to restore them.''
*.msf files are indexing files. They do not contain emails.
If there is eg:
Inbox file with no extension is an mbox file; this is the file with emails.
Inbox.msf is the indexing file. Does not contain emails.
If you have imap mail account, then you would need to synchronise a subscribed folder to get a copy into your thunderbird Profile. Then it will create an mbox file.
If the Folder was only a subscribed folder, but not synchronised, then there will not be any emails stored in your profile folder.
Subscribed foldres only download headers and when you select to view an email, a copy of the folder or xx emails if that option is selected, is downloaded to a temporary folder which is used to get quicker access to emails. These emails are not stored in your profile, they are stored on the server.
So, please tell us what you use.
re: mail accounts 1, 4 and 5
Are the mail accounts IMAP or Pop?
If mail account 4 and 5 were IMAP mail accounts, then these emails will be stored on the server.
So create new IMAP mail account and you should see all emails on the server.

Erase and Install
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

Safari opens but will not load the page after I erased my hard drive and reinstalled yosemite. Anyone have a solution? I have to restart for safari to open and load.

Hi everyone.
I recently erased and reinstalled Yosemite on my iMac 27 (model late 2013). After I reinstalled everything i've noticed that when it goes to sleep/nap and when I come back to it and open the browser (safari) it will not load. I have to restart the whole iMac for it to work. I've erased and reinstalled again and I still have the same issues. Can anybody help?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

TS1363 The "ipod has been detected but could not be identified properly...." message occurs when I plug it in. This started happening after having replaced the hard drive and operating system. Is there any way to fix this problem? I have tried all the

Ever since having to replace my hard drive on my laptop and also the operating system, I cannot get my ipod to work with my laptop. I continually get this message. I have tried every troubleshooting procedure repeatedly and also have tried all the posts on the support communities. Can anyone help?

Nevermind that first part as I forgot that nothing shows up for the Nano at all in Device Manager,
The 2nd half of my reply still applies:
Otherwise, try uninstalling all USB root controlllers from your system, rebooting your PC, and reconnecting your Nano. This root controller drivers will automatically be re-installed upon reboot.

HT1727 My old computer died before i could put my new itunes purchases on it. Is there anyway to get them to my new computer? The hard drive somehow fried and is of no use.

I had just purchased like $30 worth of new songs and my old computer. two days later it died on me before i could upload them onto my ipod touch. i tired to get geek squad at best buy to transfer all of my music from my old computer to the new one but they said it could not be done since i somehow fried the hard drive. so i was wondering if there is anyway to get at least my newly purchased songs back? i got my old purchased songs off of the ipod i just want the new ones.

It has always been very basic to always maintain a backup copy of your comptuer for this very reason.
Use your backup copy to put everything back.
If for some reason you have failed to maintain a backup, not good, then you can redownload some itunes purchases in some countries:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

I just replaced the hard drive on my Pavilion dv4 and now my screen wont turn on.

Ok so my original hard drive in my HP Pavilion dv4 shot craps last week so I bought a new WD 500 gig for it. Prior to removing the old drive and installing the new drive my screen would light up and work properly. Now that I have replaced the drive my computer seems to be booting up but my screen does nothing but stay completely black. I know my drive is installed correctly and I'm pretty sure I haven't jarred ne thing loose in the process of changing out the drive because I only opened up the hard drive compartment to do the swap, which was extremely simple. I also was sure to remove the battery, unplug, and ground out ne static electricity before doing ne work on my computer. Im at a loss for what to try to get my computer back in working order. Ne suggestions would be greatly appreciated. Thanks

Thanks for ur quick reply to my problem. I tried all of that with no results... I did notice tho that the lights next to and above my caps lock key and my num lk key are now flashing. They flash in unison three times then there is a two second pause then they flash three more times and this repeats. They may have been doing this before I tried this solution but I did not take notice until now... I was also wondering how I am supposed to know, after pressing f10 to enter bios, how I can tell if my new drive is being detected when my monitor will not function? Was pressing f10 supposed to possibly make the monitor turn on? In a last ditch effort to try and further identify the problem, I re installed my old drive. Before replacing it my computer would begin to boot then display a hard error that would not allow me to continue booting and run Windows. My display would still work but I could not run Windows. After re installing the drive the monitor will not turn on. I'm beginning to think that I have a bad monitor. Is there a way of testing this with out buying one? Where does the monitor connect to the mother board? I wonder if maybe its been jarred loose, although I highly doubt it, it may still be worth looking at. Thanks again for your advice.

I have a 1st Gen Time Capsule 1tb. It turns on, boots up and turns green for 5-10 mins, but then turns solid orange and then blinks orange. I have removed the hard drive and replaced the power supply . . . still the same problem. Suggestions?

I purchased a used 1st Gen Time Capsule with a 1 tb hard drive.
When I plugged it in and did the initial setup, it worked fine, but gave me a hard drive error. A few minutes later the green light turned solid orange, then blinking orange, then the status light went off. The lights in back stayed on.
I removed the hard drive and rebooted, it turned green for 5-10 minutes then reverted back to a solid orange, blinking orange, then went off.
Next I purchased a remanufactured internal power supply, and installed it (without the hard drive in). It turned green almost immediately. After about 15-20 minutes, I decided to try to install the hard drive again, booted it up, and tried to erase the hard drive with was working properly according to the software. It stopped erasing the disc after about 20 minutes and turned solid orange again, then blinking, then no status light (but back lights were still lit).
I'm a bit flabbergasted at this point, any suggestions on what to do next? I think i've pretty much replaced everything except the logic board, but can't seem to find any information on the symptoms of a logic board malfunction.
Thanks!!!!!!!

A Gen3 is identical board to a Gen4 although they have some differences in firmware and wireless card was updated on every model.. but a Gen3 is substantially faster than Gen1, Gen2 which also have identical boards.
You can with careful shopping get a Gen3 pretty cheap.
Most use a delta power supply which I think is a lot better than the flextronics used in most Gen1/2
You can sell back the parts to ebay.. people still would buy the power supply etc. Even just the case can be useful to a repairer.
But if the board is gone.. it is hard to repair.. not impossible.. but hard.
Gen 3 and Gen 4 are not without faults.
See this page.

I have fixed it a different way.. by using the small converters you can buy in bulk from ebay for $1 each.. KIS3R33 .. they produce 3.3V at 2A peaking at 3A.. amazing.. I keep using them to replace onboard power converters by removing the inductor and simply power directly.. the end result has worked great. You can simply change the resistors around and get any output from 1v to 20v depending on input.
Is it worth doing it .. no of course not.. it will waste many more hours than $50 is worth.. but it is kind of fun that you can actually make things work again.
Here is a pic of the Gen 3 totally powered by me. All onboard power removed.
This was to track down the fault in the Gen3.. but I am kind of pleased that it ended up neat enough and reliable enough to work for more than a year.. the Gen3 still serves as a way to get Netflix via network for a friend running 24/7.
The units supply (from left to right)
1v, 1.1v, 3.3v, 5v, 1.8v
It is feed by 12v supply which is also directly connected to the hard disk.
So it is possible to fix.. !! Only got to be a bit crazy.

Do I need to turn off File Vault before I erase a hard drive?

I have a File Vault 2 password set up on my Mac, in addition to a firmware password. I'm selling the computer, and I want to make sure everything is wiped out.
I know how to turn off the firmware password. However, I was wondering if I need to turn off file vault 2 before I start up the OS in recovery mode, at which point I will erase the hard drive using the 7-pass delete option in disk utility. Or do I not have to worry about that, and go ahead and boot up on the internal system HD in recovery mode to delete the HD entirely, without turning off File Vault first?
Thanks for the help,
Eric

Boot from the installation disc that came with the computer and repartition the internal drive with the default options. Then install the original OS.

When I try to turn on Home Sharing, I get the message: "Home Sharing could not be turned on because of an error (5506)." What does this mean please?!

I had the same error it was due to a program called Little Snitch, it's somewhat like a firewall. I changed the settings in Little Snitch to allow network connections in iTunes and now I can enable Home Sharing. Maybe you should try changing some firewall settings.
