  • Setting privacy pane to always block cookies on my brand new MacBook pro doesn't seem to work

    Setting privacy pane in Safari to always block cookies on my brand new MacBook pro doesn't seem to work. None of the settings seem to make any difference. What gives?

    Are you not able to start aperture on your old macbook? If you are able to then you can retrieve your serial number by clicking on 'about aperture'
    If not then it's a call to apple as the above posts suggest. I did when I lost mine, bear in mind though, they may ask for your original receipt as they did with me and I had to fax it.

  • Brand New Macbook Pro one of the USB wont recognize device

    Hi, I recently acquired a brand new macbook pro i5 core model for school. It was running perfect and I was so happy with my machine the last few days then suddenly last night my mouse didnt work no more. I thought it was strange so I tried the port that was closer to the power adapter and it worked in that slot. I tried plugging it into it several times again and no luck. I tried restarting my computer, no luck. I tried plugging in my Ipod nano, no luck but works in the other one. I went on here and looked for options. So then I tried resetting the Pram, and the smc, several several times, to no avail. I then even got this thing call usb prober and that didnt make it recognize it either. I am at a lost of what to do. The strange thing is though it WILL run my laptop cooler, it just will not recognize any devices?? Any help without having to go to a Genius would be great, thanks

    Welcome to Apple Discussions!
    Your USB port may not be delivering the power it should. The best thing to do would make an appointment at the genius bar and have it evaluated. You are under warranty, and this sounds like it may be a hardware problem that Apple needs to fix for you.
    Good luck!

  • One usb port stopped working today

    One of my USB ports stopped working today. I think it may be related to Itunes update today. Has anyone else seen this recently? I restarted my computer - but that didn't help. I have a MacBook Pro - running Lion 10.7.5
    Any suggestions? I saw one USB Hub when I went to Apple --> About this Mac, but couldn't tell if both were there.

  • MAC PRO Internal USB ports stopped working

    Hello, I have a mac pro 8 core with an USB internal ports problem, the 2 in front are not working anymore, and from the 3 in the back only the middle one is working.
    I tried to pull all the power out for a whole night, resetting the pram and nvram but nothing helps.
    When for example I put in a keyboard in one of the ports that is not working and when I power up the machine and I press the ALT key I get the choice of startup preferences, once I select one, and the system boots up the ports stops working, so before the OS loads the usb ports are working !!!
    What to do ??

    This is a hardware failure. While USB ports on the whole are just not designed very well, leading to their failures being pretty common, your issue sounds a bit more like the USB controller chip is failing.
    In any case, the answer is to take it to a repair shop. If they're smart about it, they'll replace the logic board and see if that also fixes the front ports. If not, they'll replace the front I/O panel as well.

  • Late 2011 MacBook Pro; one USB port not recognising anything

    Hi,
    I've had my MacBook Pro since January 2012, so I believe it is the late 2011 13" model. I'm currently running OSX 10.9 although the problem I've been having has been going on around 3 or 4 months, I think I had OSX 10.7 installed when the problem started.
    One of the USB ports on my Mac (the one on the left when looking at them face on) is not recognising my external hard drives, or recognising/charging my iPhone when plugged into the USB. The other USB slot works fine and recognises external hard drives, however when I insert the hard drive into the faulty USB input, although the hard drive lights up and starts whirring as if it is ready to start functioning, it does not appear under the 'Devices' tab of the Finder screen, but does appear and function when using the other port.
    Similarly, when I plug my iPhone 5 into the faulty port it is not recognised/does not start charging, however if I leave it running and come back later I often have at least a level of increased battery life which suggests that it does intermittently charge from time to time, and again it functions normally when using the fully functional port.
    I've tried the NVRAM reset as I have read in another post but to no avail. Is this likely to be a mechanical fault over a software problem, and if so what could be wrong with it?
    Thanks for the help in advance.

    thank you shootist, at least now I know the problem is as serious as I dreaded, but will not loose hope waiting for a miracle and the port works again

  • I have a brand new macbook pro that i was doing a data transfer from an old macbook, it got stopped/cable pulled out, now have spinning wheel of death that wont stop, how do i reboot/stop the wheel of death and start again?

    i have a brand new macbook pro that i was doing a data transfer via firewire from an old macbook, it got stopped/cable pulled out, now have spinning wheel of death that wont stop, how do i reboot/stop the wheel of death and start again? (this time il use time machine transfer)

    Just power off the machine(s). Shut them down. Migration Assistant gets 'stuck' sometimes - best way to migrate really isn't over Firewire, though it will certainly work, but with both machines hardwired via Ethernet to the same router. You can use a TM backup, too, of course, provided that it's recent. Which is the best? Your choice. I've done it both ways and have a preference for MA, but TM restore can be a bit faster and less quarrelsome.

  • My brand new MacBook Pro retina display not charging the battery any more after 3 weeks...no green or red Led. Any one now about this problem? Thanks

    My brand new MacBook Pro retina display not charging the battery any more after 3 weeks...no green or red Led. Any one now about this problem? Thanks

    Either the power brick is damaged, or the charging circuit is on the blink, or both. Either way, a trip to the Apple Store or the Apple Authorized Service Provider is in order, as this ain't no bargain basement toy.
    In the meantime, can attempt an SMC Reset to see if it helps.

  • USB Ports Stopped working on MacBook Pro 13-inch, Late 2011, OS X 10.8.5

    Please help with any advice
    I have OS X 10.8.5
    One USB port stopped a while ago
    The other stopped yesterday.
    I have reset the PRAM
    I have also reset the SMC
    Nothing seems to fix it.
    I do have a time machine backup
    Any suggestions?

    The best option is a visit to the Apple store genius bar for a FREE evaluation.  You have tried all you can.

  • USB ports stopped working in my Macbook Pro

    USB ports stopped working in my Macbook Pro

    I do not know anything about audio consoles nor do I have an iPhone.
    My iPod also does not show on the desktop but it is recognized in iTunes,  Check if that is the case for your MBP. 
    Do you have the appropriate boxes checked in Finder Preferences?
    See if this support article is of any assistance:
    http://support.apple.com/kb/TS1410
    If you have an external HDD, connect it to your MBP and see if it is recognized.  If it does not show on the desktop, check Disk Utility.
    Have you tried all USB ports?  It could be that the problem lies in your MBP.
    Ciao.

  • Strange wifi problem on a brand-new MacBook Pro

    Hey there, I'm new here. Desperation has got the better of me, and I hope I can get some advice.
    So, last sunday I bought a brand new 13" MacBookPro with 2.8g i7 processor and 10.7.2 OS (I can't update to 10.7.4 because System Update tells me the download has been tampered with or corrupted after I waited 2 hours for it to finish, but I'm trying a direct download from the website). Here's the exact product: http://www.amazon.com/Apple-MacBook-MD314LL-13-3-Inch-VERSION/dp/B005CWIZ4O/ref= sr_1_5?ie=UTF8&qid=1340301247&sr=8-5&keywords=macbook+pro+13
    Everything is all perfect except for a strange wifi problem. Note that the wifi does not turn-on or off, it doesn't disconnect after 'sleep', it doesn't get less speed, it doesn't constantly leave a preferred connection (once I chose my home wifi it always connects to it no problem). The wifi bar is always full. What is wrong is that the internet is kinda 'glitchy'. The best metaphor I can think of is that it's like a car that has to be pushed down the road before the engine can start. Please, bear with me because this is kinda hard to explain and I'm not good at tech lingos.
    One of the symptoms is browsing can get really slow and inconsistent, almost as if the wifi gets turned off in the middle of browsing. For example: if I look something up on Google and then open 5 new tabs, probably only 2 or 3 of those tabs will eventually load while the other two will not get past the long 'http:.......google.....etc etc' address and will eventually show one of those 'error loading page because there's no Internet connection' notice. This happens a lot. Sometimes I have to refresh/retry loading a page a couple of times before it finally loads, then usually everything will get back to normal and I will be able to open multiple tabs with no problem, but in a couple of minutes I would try to open another site and the problem will start again.
    So I tried to see how it does with downloading using iGetter. Fortunately I also have a Macbook (white-plastic casing one) and my brother has an old 2006 MacbookPro so I can compare. With those two older Apples iGetter starts receiving data in less than 8 seconds after I click Start, while my brand-new Macbook Pro can take up to 15-20 seconds, sometimes it doesn't even start at all and I have to re-click the start button. But once the download actually starts (on my new MacBook Pro), it downloads like normal, it doesn't stop and the speed is also as good as I can get. Strange huh? Hence, like a car that has to be pushed before the engine starts.
    I also tried 'speed testing' from a website with all 3 laptops. On my old MacBook and my brother's MacBook pro, once I click 'begin test' it takes only a couple of seconds of 'ping' before the download/upload speed measurements start, but with my new MacBook Pro (just like with iGetter) it takes up to almost a minute before the measurements start, sometimes it won't start at all and I have to re-start the test.
    Well, thanks for reading. And hope you can help me shed some light into this. Because it is really preventing me from really enjoying my new MacBook Pro. And if this is most likely a hardware problem, I'd better get back to the store and try to get it replace or something while it's only been 5 days. *cheers*

    Hey guys.. Thanks for the replies. Unfortunately, I bought the MacBook in Indonesia where there are no such thing as an AppleCare. The only option is to leave the Apple product to one of the 'Authorized Apple care centre' and have whoever do whatever to it without guarantee of success. As for returning it and getting a brand new one, I also don't know if there is such a deal here, but that's actually a good idea, will try to go to the store tomorrow. Although, I'm worried that the problem might be with OSX Lion or something and getting a new one won't help.
    mark75090, I've tried resetting the router when I first noticed te problem, didn't work though. I've checked my new MacBook's wi-fi (option+click wifi bar) and it says 'PHY Mode: 802.11g', so does my MacBook and the old MacBook Pro. I don't know what those mean though, and I don't know whether or not my router is an N., can you tell me more please.. I have tried with the other two turned off, and only the new MacBook using the wi-fi but the problem persists. I have also tried connecting directly to the router, but as I described, the problem is too subtle for me to notice the difference.
    Also, if I create a brand new Wi-Fi connection in network preferences and connect to my router through the new Wi-Fi profile, the problem seems to be gone for an hour or so, then it always comes back though. I have also just finally installed 10.7.4, but it doesn't help either.

  • Can I run OS 10.6.4 on my brand new MacBook Pro?

    I am a professional photographer and one of the programs I need in order to do my job is some software from Nikon that apparently will not run on Lion, OS 10.7.3.  Documentation says that it can run on OS 10.6.4, Snow Leopard.
    Can I run OS 10.6, Snow Leopard on my brand new MacBook Pro, 2.8Ghz, Intel Core i7 machine?

    You cannot install any of them. As I said earlier your only options are 10.6.6 through 10.6.8 none of which are on a retail DVD.
    If you have access to a Mac that runs 10.6.4, then you can put a small system on a 16 GB USB flash drive, boot from it then upgrade the system to 10.6.8. Now, see if you can boot your new computer with it. If so, then create a small partition on your new computer's hard drive large enough for the Snow Leopard system and whatever applications you need to use. Clone the USB flash drive to this partition using the Restore option of Disk Utility:
    Clone using Restore Option of Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the new partion on the internal drive. Source means the USB flash drive.

  • Brand new MacBook Pro – 'sticky' keys

    Hi all
    I just bought a brand new MacBook Pro retina 15", which came with Mavericks pre-installed (currently on 10.9.1).
    I've been having a really irritating issue with the keyboard since I started using it. The Mac seems to think that certain keys are 'sticky' – this is not a physical problem, but a virtual one. It's incredibly hard to describe, but basically, every few minutes, a (seemingly random) key will act as though it is stuck down. Not on the physical keyboard itself, but on screen. It really frequently happens when I use command+tab to switch apps. I'll hit the keys once, but all of a sudden the app menu will stay on screen, with the selected app cycling round indefinitely – even once I have let go of the keys. Also, in Photoshop it seems to think the space bar is held down a lot of the time, so I can't click on anything until I hit space again to disable it. Another instance is hitting command+C to copy, and it not registering. So I have to hit it again.
    My usual set up is to use a wireless (bluetooth) Apple keyboard and Magic Mouse, with a Wacom tablet plugged in via USB. However I have systematically tried various things to narrow it down. At first I thought it was the Apple wireless keyboard, but that works just fine on my old iMac. Then I thought it could be my (fairly old) Wacom tablet causing the problem, but that works OK on my iMac too.
    I have turned off both Bluetooth and wireless on the MacBook, and unplugged the Wacom, and the issue persists even when using the built-in keyboard and trackpad.
    Anything I can do, or should I take it to an Apple Store?
    Thanks

  • Brand new MacBook Pro OS X Lion turns off when iPad connected

    I have a brand new MacBook Pro and I connected mt iPad to it tonight. I have connected it once before sync it when I got the MacBook. Tonight every time I tried to connect it the MacBook would turn off (poof!) When it turned on, It came up with a USB disabled as something draining too much power message. The laptop is plugged into the mains directly at the wall socket.
    I tried a different cable and it causes the message or shuts off the laptop. I used the same cable in my husband's iPhone and it is working.
    Is it the MacBook or the iPad? It is a 1st gen still under warranty. What should I do?
    All help will be appreciated. I reset the PRAM already.
    Thanks

    Can you run an Internet Speed Test? Reboot first and don't open any programs but Safari to perform this.
