Need help with mac stuck in start up

I was only able to boot in safe mode. I reinstalled os x 10.4 and it rebooted fine. On doing all the updates on the 3rd reboot it is stuck in a blue screen recycle after the mac os x start up screen. Windows starts okay. The extra problem I have is the internal d drive does not work and I use an external dvd drive. Would appreciate any help. I have flashed the pram. I think it might be related to the last updates.

What happens if you run fsck?
Run fsck.
1. Reboot/Startup holding your Command-S key down.
2. At the command line type the following and hit 'Return.'
/sbin/fsck -fy
3. If it finds a problem and repairs it, immediately run fsck again until the drive checks OK.
4. After it has check/repaired your disk, type 'reboot' and hit 'Return' again.

  • Need help with mac and java

    Hi, I'm trying to develop an application on a Machintosh OSX 10.2.8 machine.
    I'm having a herrendous time trying to get quicktime to work on it.
    I've somehow managed t oget 1.3.1 and QTJava.jar to work together but now i need encryption, however that requires 1.4+
    Now 1.4.1 doesnt work with quicktime
    I've downloaded the latest software upgrades but Ive got no idea how to set up quicktime to work with java 1.4.1
    Now to add on top of that mac reports it can use AES encryption. this is from source code ripped striaght from this website.
    But first and foremost can anyone, annyonee help me out with setting up 1.4.1 with quicktime?
    Thank you

    If you need encryption with Java 1.3.1, download the JCE from either Sun (http://java.sun.com/products/jce/) or Bouncy Castle (http://www.bouncycastle.org/).
    Cheers,

  • Need help with Mac Pro purchasing decision

    I've read preliminary reviews on the new Mac Pro, and I'm ready to upgrade my current Mac Pro (which is Dual 2.4 Ghz Quad-core with 32 GB RAM).  But I'm going through some major turmoil in the decision.  My current Mac Pro, aged as it may be, has been good to me, and when it needed upgrading, it was so easy to do.  I installed an additional two internal hard disks, giving the Mac Pro 3 TBs of internal storage.  RAM upgrade was a breeze, and when the graphics card went out, I was able to buy and install a replacement without a hiccup. 
    I love the low profile of the new Mac Pro, albeit I'll still be putting it on the floor - I don't like having my desktop computer in my desk work area.  And it looks like upgrading the RAM in the new Mac Pro is pretty simple (although horribly expensive).  I would require a CD/DVD drive, so that becomes a piece of "stuff" I have to clutter my work are with.  However, most importantly, the internal storage issue, FOR ME, is huge.  Without the ability to add internal drives, getting the 1TB flash storage is a must, but sooooooo expensive.  AND.. I still need additional storage (more than half of my current 3 TBs is in use).
    Moreover, the whole lack of upgradability has me concerned that the new Mac Pro may disappear like the G4 Cube.  I haven't seen any rave reviews of the new Mac Pro overall.
    But I need to upgrade.
    I have configured a new Mac Pro on the Apple Store about 100 times now, but never making the purchase for all of the above reasons, as well as the $5K price tag that it keeps ending up at.   I even started looking at refurbished Mac Pros (newer than mine, but the same old huge silver case).  The advantage is that it's upgradeable, and I won't end up with an optical drive or external hard drives cluttering my desk space. 
    The truth is, every time I go to buy, either a new Mac Pro, or a refurbished one, I hit a wall.  I'm walking the fence, wondering if I should walk it until a newer Mac Pro shows up with more expandability options (although it seems unlikely since Apple's direction seems to be form over function). 
    The new Mac Pro has been out for awhile, so I am looking for feedback from people who are kind of in my shoes, but already bit the bullet.  I don't want to encourage replies of regret, but I also would prefer the truth over grandiose reviews simply to justify making the leap (and dropping some huge bills).  It happens... "I just spent 5 grande, I better **** well love it, and I'll make sure everyone else thinks I do!"   ;-)
    Please share your experiences.  How have you gotten around the lack of upgradeability on the internal storage?  I have had bad experiences with external drives in the past.  Firewire drives were fast and furious, but the were not as reliable as internal drives.  USB drives lag, and that dreaded spin up time every time the Mac OS does something that wakes up all the drives, even if the external drives weren't actually being accessed (never had that problem with Firewire drives, maybe because they were always spun up?).
    Anyway, I don't want my buyer's pain to turn into buyer's remorse, so I appreciate all the wisdom any of you would be willing to share.
    Thanks,
    Bill

    I'll offer my comments although there are others much better qualified to answer than I am.
    First, the reason I bought the machine that I got was that I found an "open box" deal at a local retailer and got a substantial discount from the normal list price. Otherwise, I might not have gone to the nMP quite as quickly as I did. Regarding ram and the ssd drive, both of these can be upgraded at some later date if I find that is needed. The ram I will probably bump asap, filling the one empty slot with likely an 8gb OWC module.
    To run your VGA monitors, you will need 2 passive mini-display port to VGA adapters. You can buy these pretty much anywhere, the Apple ones are superb quality at a price but other options are out there. These will plug into 2 of the Thunderbolt ports on the nMP.
    Regarding cpu's and gpu's it gets a bit confusing. Basically right now it depends on the software that you are going to run. It is not likely coincidence that FCPX 10.1 came out basically at the same time as the nMP, as it really highlights full use of the multicore cpu's plus the dual fast gpu's. FCPX really screams on the nMP.
    Right now, it seems more video software is making optimum use of both the multicore cpu's and dual gpu's in the nMP. Other software, most notably photo software that should also benefit, is lagging behind. For instance (going only from memory) Adobe software is not very good at using multi-core cpu's nor does it use multiple gpu's either. You can find comparisons of running Photoshop filters on a 3.7ghz 4-core vs the (slower clock speed) 6 or 8 cores and the 4-core comes out close or even faster in some tests because Photoshop uses only a single core, which on the 4-core machine is faster.
    However, this is a pretty specific instance and generally buying the fastest cpu and gpu that you can afford is a good plan. Especially so for the gpu's as right now, the video may end up being the only component that does not end up with some sort of upgrade option in the foreseeable future.
    If I was going to order a system under the circumstances you have stated, the 6-core with the D500 gpu's sure looks like the sweet spot in the lineup, and probably money well spent. After I would probably upgrade the ssd next, since in order to upgrade it later you have to remove a perfectly good ssd since there is only one slot. Personally I am ok with the 256gb as my boot and system drive, since with Thunderbolt you have basically PCIe access to an external box that can have either Sata or PCIe expansion for whatever storage you can afford.
    As I said earlier, right now I am going cheap and using Apples Thunderbolt to firewire cable, which is allowing me to run my existing Lacie firewire drives in a daisy chain just as I did on the old MP.
    Upgrading the ram at purchase or later is your choice, there are certainly less expensive options but with only 4 slots you have to weigh the cost of discarding or trading in the original Apple ram when you decide to swap it out for bigger modules. Plus not all ram can be mixed and matched, you may have to remove all the existing ram in order to add just a single high capacity (16gb or larger) module.
    Again, hope I have helped more than adding to your confusion.

  • Need help with Mac & PC not recognizing external drive (disk not readable)

    I am having trouble getting my computer(s) to recognize my Seagate External Drive.

  • Windows 8.1 need help with Windows Updates and Start menu Or fix my old Windows Xp system

    My beloved windows Xp has gave up after many years of working well. It stopped working a few days ago after a lightening strike.
    I got this Windows 8.1 computer a few month ago  but it seems to have a problem. I stopped using it after could not get start menu to work and when back to my Windows XP system.
    First problem is the start menu is not there. I tried installing something and it says it will take control or something and screen goes black. I clicked canceled quickly in order not to get a virus.
    Where is the start menu?
    Second problem, Windows updates does not want to update because it needs Windows 8.1 update. This computer is already Windows 8.1. There I canceled it since it was mostly a virus. Now updates are not working.
    If those can not be fixed, how can i fix my Windows Xp to get it back. It does not turn on, I press button and nothing happens. Is this something easy to fix?

    Another user discovers that Windows 8.1 is not at all of what it should be.
    There is no Start Menu in Windows 8 or 8.1.  However, you can restore your desktop start menu with a very good freeware application: 
    Classic Shell
    Windows Update comes with Windows 8.1.  There is nothing special you have to do.
    It kind of sounds like you've been a bit too quick to download and run whatever you find on the Internet.  You should always research any software you're considering downloading/installing ahead of time.  Google it.  See what others say
    about it.  Ask on forums.  In order to use Windows effectively and safely you need to expand your knowledge and become a more sophisticated user.
    If you think your new system has become infected, you might want to consider Refreshing or Resetting it to a clean state, or at least visiting one of the anti-malware forums and getting some advice on cleaning it up.  But beware, a lot
    of "blind leading the blind" happens on forums.  Always try to read between the lines, and question what people say.
    You could consider leaving XP behind.  Its time has come and gone, and pretty much any newer version of Windows can actually give you better service than XP - once you get it tuned up.
    It's possible to make Windows 8.1 more functional than XP and about as functional as Windows 7, but it takes a fair bit of effort in reconfiguration and installation of some well-known 3rd party applications that are good (which, unfortunately, most
    on the internet are not).
    Good luck to you.

  • Need help with Mac Pro (2008) iCloud sync problem

    I am using a Mac Pro (Early 2008) with multiple drives and partitions, some of which I use for various software testing.  I wanted to have access to the same data on various partitions, so I tried to use iCloud to store some Pages files. I found that in the Mountain Lion Partition that I normally use, that the document data ( Pages, Numbers, etc) would not upload to the cloud... just showed as waiting. All other iCloud Data ( Calendar, Address Book , etc) did sync fine. If I accessed iCloud using a browser or looked on iClould using the iCloud Manage function in the iCloud system preferences, I could see all the files.  I then found that I did have another Mountain LIon partition in which the data syncing all worked.  Other testing showed that if I did a clone of the working partition using SuperDuper, the clone worked properly, but if I did a clean install of 10.8.4, the document data did not sync.If I did a clean install and used the migration assistant to migrate from the working partition, it still did not work.  I later found that if I replaced the top level Library file in a non working partition with the one from the working partition, that I could make the non working partition sync properly. I have not been able to find a subset of the folder that would make things work, but have not tried every combination. At this point my only conclusion is that there must be a bug in the 10.8.4 installer. Apple has been working on this for a few weeks, but has not found anything and cannot duplicate... but they are testing with iMacs.
    Is there anyone with a Mac Pro (2008) who can do a clean install of 10.8.4 on a partition and see if they can still access their iCloud data (Pages, Numbers, Etc). If so that would probably confirm the otherwise unexplanable problem.

  • Need Help With Mac Mini Networking

    I sure could use some Apple Expert advise:
    I am having quite a problem getting my mac mini to see my Windows (Vista-XP) network. I am only able to see one of my systems when I use the smb://command. First I used this command from the address bar of Firefox, it connected and mounted the drive on my mac desktop.....would not see any of the others. I have (2) Leopard books and have followed the steps correctly.
    Went back to the store-local and we did the same functions and without fail the systems showed up quickly in the finder as shared.
    I have the WINS: NETBIOS name and Workgroup name correct. I have file sharing, screen sharing turned on.
    Can anyone give me some thoughts as to what I am missing here. Again unless I use the smb://command nothing shows up. I have the Finder set to show shared.
    Connection to the wireless net, perfect-less than a minute to complete.
    Thanks in advance

    Windows PCs aren't visible from the shared area.
    Here's a tip: write an Automator application to mount the computer's C drives (you will need 1 app per PC). Then, run that app and open a Finder window and then the PC's IP address will be visible in the shared area. Make sure you know the PC's IP address. Then for convenience, give your new apps their own snazzily named folder and drag that to the dock and make a stack.
    Another thing: if you don't already have one, setup a password for your desktop because if there isn't one, serious problems will occur.

  • Need help. Mac won't start up from HDD

    My problem is: I went to system preferences, chose network startup from the Startup menu. My mac rebooted itself and tried to connect from a network drive. After it didn't find any network drive I force restarted it. When it booted up again it was the flashing question mark folder on the start-up gray screen. I followed everyone i knows advice to try to start it up from the start-up disk.
    I also tried holding Apple-s. I held down the command button, option button, and control button for a least 45 seconds each. Nothing has worked.
    I am 100% positive that it is because the computer will not start up from the Internal Hard drive, Which i am also 100% possitive is not broken or corrupt. I can use all the advice and solutions you guys will give me.
    Thank You,
    Brody6786
    p.s. the following keys don't work on my keyboard:
    both shifts, z, a, q, 1, f1, delete.
    I have an external keyboard but it seems it doesn't turn on until the gray screen appears.

    HI,
    When it booted up again it was the flashing question mark folder on the start-up gray screen.
    That can mean several things. One, your Mac can't find a System Folder to boot from. Or two, the hard drive is failing or failed.

  • Need help with Mac Book Pro?

    When I start the mac book pro, the disk drive keeps making noise. The computer can't get any further. Its like its looking for a disc startup. I put the start up disk in there and now it doesn't do anything. Its almost as if it won't boot the hard drive. Any advice would be appreciated.
    Thanks, Matt

    +the disk drive keeps making noise. The computer can't get any further.+
    That's sounding like a hard disc failure sadly ...
    +I put the start up disk in there and now it doesn't do anything.+
    Restart holding down the 'c' key to force it to Boot from the DVD, if that works select Disc Utility from the top menu bar and then 'Repair Disc' and 'Repair Permissions' on the Internal Drive. Post your results here.

  • I need help with my adobe photoshop starter edition

    hello! the licence of my adobe photoshop starter is over and my problem is that my photos are inside the programm and I cannot see them. How can I do to get my photos?

    Your photos are never stored inside the Photoshop Starter Edition. They are always stored somewhere on your hard disk where you can find them.
    What is stored in your Photoshop Starter Edition (in the "catalog") is all the organizing you have done (tags, captions, etc.) If you want to retrieve this information, you could download PSE 11 and then try to convert/upgrade the catalog, which would make this infromation retrievable and usable.

  • I need help with Mac Mail

    "The Yahoo! IMAP server “imap.mail.yahoo.com” rejected the password for user "******""
    Why does this happen? I enter my Yahoo password correct and i click "Remember in Keychain"
    Wondering how i fix this. Thank you!
    <Email Edited By Host>

    If you haven't made any changes and suddenly the Mail program tells you a password is rejected, in most cases the password is just fine and there's nothing wrong with your computer. There's a little dance that goes on between your computer and the mail server when you check your mail and each step has a time limit set to it. If at any step time runs out the dance ends and Mail tells you there was a problem and in most cases the error message tells you that the password failed rather than reporting there was a time out error.
    There's a reason for this that only programmers would care about. In most cases if you ignore the error message and try again later your mail comes through. What's really crazy is that sometimes (and this happened to me with both iCloud and gmail earlier this week) you can't get mail with the Mail app but you can log in with Safari and get your mail just fine. That's nice because you can verify that you really do know your password but annoying because it makes you think something may be wrong with your computer.

  • Need help with iMac intel desktop - Mac mail consistently going OFFLINE

    I need help with Mac mail - it is frequently going "offline" and requesting me to "take all accounts online". My internet is working. It's been checked, checked and checked. Sometimes it just takes a reboot of the system and the modem to kick it in and make the little triangle symbol go away, but should I have to reboot daily? I have the Mac OS X Lion 10.7.5 installed. Is there a bug here or am I supposed to upgrade to Mavericks? Any help is most appreciated.

    For me this is an issue caused by my email service provider.  When they are slow to respond or to accept the password Mail takes that as a password rejection, and prompts me to reenter password, and eventually goes offline.
