HT1310 I press option when starting up my computer and it just hangs or at least never gives me the list of startup disks before it's booted up.
I press option when starting up my computer and it just hangs or at least never gives me the list of startup disks before it's booted up. I can choose which startup up disk when I'm already booted up from settings --> Startup Disk but how do I know if my Macintosh HD internal drive disk fails I'll be able to boot from my supposedly bootable backup drive?
What am I missing? I have the latest Mountain Lion, could this be bug in that new Op System?
Does the startup drive list (before bootup) only show up if the Macintosh HD is not bootable (crashed or broken)?

Replugging my keyboard into my front USB2 slot was half the solution. I had my keyboard plugged into a KVM switch which goes into the back. The other half was that I needed to unplug my backup firewire hard drive from the front port to a chained drive with the source hooked into the back of the Mac Pro. Not sure if it was the cable or the firewire slot that gummed up the hardware startup hard drive selection diaglog.
I also tried resetting the NVRAM and only got one Mac startup sound. That didn't seem to do it but then again it could of been a necessary condition as well.
Thanks everyone for your help.

I have MBP 17" running OS 10.9.2....... I need to have OS 10.6.8 so I can contiue running Quicken 2006. I have this on my Mac Pro but am switching to iMac and hence will dedicate laptop to finances. I pressed option when starting and got disk utilities and erased the HD..... I put in the Snow Leopard disc and pressed C when starting but then when I try and install it shows icon of my HD and says I cannot start up from that disk....... I get the same thing when I insert the #1 instal disc that came with the computer. How do I instal OS 10.6.8 (if I go recovery mode it will insatll 10.9.2 which I don't want on this laptop.
Thanks for any help.The grey disk says OS 10.6...... i tried it as well as the SL disk with the C pressed....... what happens is that it directs you to agree etc and then asks where you want it installed..... the icon of the computer HD however has the yellow exclammation sign saying I cannot start from that disk.
My super drive is working.......
Since I need to get to Quicken for taxes etc what I have done presently is formatted a LaCie rugged drive, partitioned it and when I attach that drive to the MBP and start up again I was able to install on the external drive....I am presently downloading the combo upgrade that will take me to 10.6.8
I still don't understand why it wont instal on the MBP I i know you cannot go earlier than what the machine shipped with but since this is 10.6 it should.I have a Mac Pro with one internal drive running 10.9.2 and the other 10.6.8 and I'd select the earlier system to start when I wanted to do my finances. I have upgraded to an iMac and hence cannot use that for acessing the earlier system
Interestingly, I partitioned another LaCie drive and was able when running 10.6.8 on Mac Pro to install on the external drive...... however when selecting that ext. HD for starting it never did restart with it , always restartd using the 10.9.2 system that was actiually on the other disc. -
Whenever I try to upload photos into iPhoto, they load but when importing it just stops a picture or two into it and then just sits there. I can't stop the import so I have to shut off my camera when it is importing and start again. Does anyone know how to fix this?
As a test launch iPhoto with the Option key held down and create a new, test library. Tru importing from your camera to it and to see if the same problem persists. Does it?

Ios7 no call decline option when its locked battert drains fast music is not able to controlled through headset unless the music app is open please fix these bugs
if they are unable to update all languages in a normal time gap (it is now 6 months ago they released firmware 4.22 for the first product code (actually mine and maybe a few others)), they should not offer those many versions. the huge bug with out of memory in nokia navigator with firmware 3.58 is not fixed yet for those people. really absolutely not acceptable.
besides that, currently my phone is in a nokia service center, microphone doesnt work anymore (the one who i call just hears a very loud noise). my brother got the same phone, his one is in nokia service center since 2 weeks now, because it doesnt charge anymore as there seems to be a connection broken inside the phone).
well that will be fun if the phone returns (approximately 4 weeks), as I guess the phones will have new IMEIs as they will send 2 new phones and not fix the problem (would cost them more). but as i got a western europe with nordics-map licence locked to the imei, the next problem will be there after I get a nokia 6110navi with another IMEI back. i get really upset with this really slow support. -

System Preferences - Users and Groups - Login Items - remove any that you don't want on startup.
Don't forget also that Lion will automatically restart any apps you had open when you shut down, unless you untick the "Reopen windows when logging back in" tickbox that appears.

I lost my IPhone 4S this morning and want to increase my cloud storage so I can back it up when it finds a signal and then remotely erase it...I'm assuming the worst that whoever finds is will not call me or want to return the phone. I went to icloud but it only govers me options to increase storage from my iPhone or a synced computer (mac or PC).
If the phone is offline there is no way to track it or send a message to it. You can place it in lost mode to lock it and send it a message (see http://help.apple.com/icloud/#/mmfc0f0165), but this will not take place until the phone goes back online, if it ever does. If it does, you will get an email informing you.

I have now transfered my files of ripped CD's to my iTunes library three times Since upgrading to iTunes 11 and Windows 8. On each occassion, the conversion seems to occur fine, the files play, but when I close my computer and return the next day, iTunes says it cannot locate any of those files. Three times. Beginning to lose my temper. Advice? Suggestions? Could the fact that my original library is located on a network drive have anything to do with it? Thanks for your help, all.
Repair security permissions
Right-click on your main iTunes folder and click Properties, then go to the Security tab and click Advanced. If necessary grant your account and system full control to this folder, subfolders and files, then tick the option to replace permissions on child objects which will repair permissions throughout the library. This is the XP dialog but Windows 7/8 shouldn't be too different.
Repeat for the media folder if it isn't a subfolder of the iTunes folder.

I am trying to free up some room on my touch and am unable to delete any songs or books from the listing. With iTumes open and my touch listed I open the touch. I then select the items I want to delete from the touch and press the delete button. Nothing happens. I have also tried to right click on the item, but a delete option is not listed. What do I need to do to get rid of some books?

When I open my computer and sign in with my password it opens and says setting up your Mac. But from here it never goes forward and even if I restart I cannot get computer to open
This sounds more like a Windows question, than a Firefox question. When you say that an image shows up every time you open your computer, do you mean every time you turn on your computer, or every time you start Firefox?

Each time I start up my computer and have my iPhone plugged in, I get a message window that eads "New Wave" file not found in your files....How do I get this file I am missing?
Hey Podieboy,
Thanks for the question. It sounds like you are receiving a message about missing files when you start iTunes. The following resource may provide more information:
iTunes: Finding lost media and downloads - Apple Support
http://support.apple.com/en-us/TS1408
If the file/song is not important, you can simply delete it from your library to avoid this error message in the future:

Thanks,
