MacBook pro and SD Slot.......

I have a 2010 MacBook Pro.
Does the SD Card slot support SDHC cards?
Is there any limit to what size SDHC card I can get?
Finally, what are the read/write speeds like when using a SDHC card (if compatible)?
Thanks

USB2 has a burst rate of 480 Mbps, but the sustained transfer rate is a little less than 2/3 that. So, the max speed of the SD slot is slower, but not by a whole lot. However, the SD card media itself tends to be pretty slow unless you get the super fast cards. The fastest card out there is 32 MB/s write, 64 MB/s read (256 Mbps / 512 Mbps) -- burst rates. Sustained transfer is somewhat slower. Basically, the fastest card you can get will work pretty much at the max speed the MBP can deal with, which is slightly slower than USB2 for sustained data transfer.

  • HT3053 I have a 13inch MacBook Pro and when I switch it on the apple logo appears then a slot and the circular symbol which is turning and then before opening the home screen it switches off again. Is there a sequence that I can use to force it to load.

    I have got a 13 inch MacBook Pro and it got stuck in a loop so I switched it off by holding the power button down and now when I switch it on the apple logo appears then I get a blank slot at the bottom of the screen then the circle appears and rotates and then it switches off again, I have tried starting it again with the system disc that came with it when it was new but it makes no difference. Is there a sequence that I can use to force it to start.

    Sorry. We can't help you. It's no longer an iPhone. Apple won't touch it.
    Take it to whoever replaced the screen and see if they can help you.
    iPhones are not user servicable and Apple does not sell iPhone parts at all. I'd be surprised if you were actually able to back it up at this point. It sounds like it's completely borked.

  • Officejet Pro 8600 - Macbook Pro and Macbook Air will not print

    Products:
    HP Officejet Pro 8600
    Macbook Pro (Mac OS X, Version 10.7.5)
    Macbook Air (OS X, Version 10.8.2)
    Question:
    Why did my Macs initially print fine, but now will not print at all?
    Full Story:
    I have a wireless network at my house that consisted of a 30mb cable internet, Netgear 900n, HP Officejet Pro 8600, 2 Dell Laptops with Windows 7, a Lenovo Laptop with Windows 7, and Dell Tower with Windows 7 - All printed just fine.
    The HP Officejet 8600 was added to my network about 2 months ago.  
    I added a Macbook Pro and a Macbook Air about 3 weeks ago.  Both Macs printed just fine for about a week.  Then suddenly they stopped.  I spent about 2 hours on the phone with HP Service, and they finally said it must be my router.  So I called Netgear.  Netgear was useless!  They wanted me to agree to charges for services before they would even discuss the issue.  
    Due to information provided by HP's service support, and because Netgear will not support their product, I promptly purchased a new router - an Apple Airport Extreme.
    The Macs recognize the printer, will print if hardwired via a USB cable, but will not print wirelessly to the Officejet Pro 8600.  The PCs print fine.  
    The frustration that is being felt is compound by the fact that the Macs printed just fine with the Officejet Pro 8600 2 weeks ago, and now the printer just shows "idle"... even with a new router. (see image below)
    Please help, I appreciate any support.  
    As a side note, the HP Service rep was very friendly, and definitely tried to support the HP Product, which is much more than I can say about Netgear.
    Thank you,
    This question was solved.

    Hi,
    More likely the issue related with Multicast, which Apple devices relies on to communicate with teh device through the network.
    First try unplugging the router for 30 seconds.
    Plug it back to the power and wait for 2-3 minutes.
    Turn the HP printer Off and back On, then check for any difference.
    If the same persists, try changing your router configuration as following
    Note: the settings below are not related with the HP product, I provide you the steps as a best effor and those are only based on my own knowledge. you may try modifying the router settings at your own risk:
    Open the router configuration page (can be found listed as the Default Gateway by clicking the Wireless icon on the printer, then print a network configuration report.
    Click the Advanced tab.
    Click the Setup option from the menu, then click on WAN Setup.
    Make sure to uncheck the box next to Disable IGMP Proxying and Apply the changes.
    Click the LAN Setup on the same Setup menu.
    Set the RIP Version as RIP-2 and Apply the changes.
    Reboot your router and then check for any change.
    I hope you may find that information useful, you may also use the user guide below for further information:

    Sounds like you'll need to access that drive while it is not booted. You need to replace it anyway, so do that, then one way or another (ext enclusure, et), access it and copy files.
    If you keep trying to boot it, you might kill it for good and not get your files, so just swap it out first.

    If the purchases are all from the same account then you can share the content by authorizing each device.
    If you have separate accounts then you have to be authorized to use the content purchased from another account.

  • After having yet another problem with my MacBook Pro and having to wipe the drive, I am now unable to sync my iPhones etc without erasing all the music on them. Is there a way around this? I have no other library!

    iTunes is a mess! It couldn't find it's own libraries and I was forced to create a new one. Now I don't know where my music is or if any's missing.

    How crap is that?
    It's not crap at all.
    It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
    There has to be a solution.
    Why not simply make a playlist with the songs you want on the iPhone?
    and maintain a current backup of your computer.

  • (Trouble printing) Trouble with connection between Macbook Pro and Hp Deskjet 1510.

    Trouble with connection between Macbook Pro and Hp Deskjet 1510. (Nothing Prints).
    I have a Macbook Pro and am having difficulty printing documents from ‘Pages' from my Hp Deskjet 1510. I have installed the necessary software for the printer and it is connected via USB. Every time I try to print the printer icon comes up as it should, 'printing' and then 'job completed' and then the icon disappears. (Nothing is printed.) I thought it might be something to do with Pages compatibility with the printer but exporting the document to Word or making it a PDF doesn’t change anything. I don’t have Microsoft Word on my computer. The scanner does work and when I printed a ‘Test Page’ that worked too.
    Let me know if you know why this is happening.

    With these settings the network now works flawlessly, however, when i have my ethernet cable plugged in, my internet access via my airport card(on the macbook pro) is no longer available. Hoping you can tell me why this would be with this info i've provided.
    Educated guess. The networking devices have priorities as to which are used. The standard order is that Ethernet has a higher priority than Airport.
    While your Ethernet is unplugged it is inactive and the Mac ignores it. Once you plug it in, the Mac sees that it is active and switches traffic to that interface.
    I actually take advantage of this feature at home, but configuring my Airport and Ethernet with identical fixed IP addresses. Normally I'll use Airport, but if I'm copying a huge file and I want faster performance, I'll just walk my MacBook (previously iBook, previously Powerbook) over to my Ethernet switch and plug in my MacBook. Magically, the Mac detects that the Ethernet is active and continues the file transfer uninterrupted over the faster 100baseT Ethernet connection. When the transfer is finished, or if I really need to move back to the Comfy Chair, I unplug the Ethernet cable, and all activity reverts back to the Airport, all without disrupting any existing networking connections.
    You on the other hand have totally different settings for your Ethernet and your Airport, so when you switch to Ethernet, you basically loose your Airport connections.
    Something you can try:
    System Preferences -> Network
    Gear icon on the bottom left, next to the [+] [-] icons.
    Select *Set Service Order...*
    Now Drag the network interfaces into the perfer priority order you want. In this case put Airport above Ethernet.
    NOTE: You may want to create a new Network Location for this, instead of messing with your normal home Location (which is most likely the default Automatic. That way you have your original you can always fall back to.
