I have a separate keyboard and mouse to use for my 13" MacBook Pro and I was wondering if there is need to actually "safely" disconnect such types of usb (like a printer) from the laptop! Thank you!

I have a keyboard, mouse, and printer that I connected to my 13" MacBook Pro through their provided USB cables. I wanted to know, do I need to "safely" disconnect these specific devices or is it ok to just pull them out? My reason why is that I had put in my USB blood glucose meter to charge on here and without thinking pulled it out––a message had popped up saying that I need to safely disconnect devices or they could become corrupted or something like that. I looked up information on how to disconnect a usb and they said that there would be an icon in Finder that I could drag to the trash and that would allow me to safely disconnect the device. If you have any information please help me because I got this laptop 2 weeks ago and I'm still learning a lot about it! Thanks for your time!

I use a usb adapter so i can have my mouse and other things plugged in all the time - i can safely disconnect the mouse and keyboard anytime with out having to eject - i would eject things like devices with IOS and external hard drives.

  • I can't access my university VPN with my iPad or iPhone but I can access it with my Mac. I was wondering if there is a simple way so that I can remotely access my home computer from the iPad, turn on the Mac VPN and then access the school network?

    The iosx and open VPN app on the iPad/phone aren't compatible w my school's VPN, but my Mac is via tunnelblick. I would really like to have VPN access from my tablet so I can access journals without undergoing a tedious process.
    Has anyone encountered this and found a remedy? I'm imagining an app from the tablet that can access the Mac at home to turn on the VPN to the school and then have access.. But then I'm thinking id be reading through 2 screens then formatting/resolution could be a problem.
    Another thought was setting up a VPN at home so that my iPad can connect to my computer at home via VPN which would then allow me easy access to journals. But I'm lacking experience in this, especially a security issue as I'm going from point A to point C to get back to point B.
    I'm open to any suggestions.
    Thanks

    You should be able to use the OpenVPN Connect app running on your iPad to connect your iPad to the VPN directly. It is an official OpenVPN client for iOS devices.
    In what way is it "not compatible"? Have you tried it? Tunnelblick is an OpenVPN client, so your school's VPN is using the OpenVPN protocol. That means any OpenVPN client should be able to access it. (It is possible, but unlikely, that your school uses encryption that is not available on the iPad, but that would be very unusual.)
    Otherwise, a remote control app on your iPad would let you control your Mac at home. "Back to My Mac", for example, would allow you to control your Mac remotely. The tricky part of this is that usually a VPN is set up to send all Internet traffic via the VPN server, and I'm not sure how that would work with "Back to My Mac".

    I too experienced the same issue.  Here are my details:
    Recently I bought a 15” Macbook Pro and last night I tried to connect and use a Edirol FA/66 Firewire 400 connected outboard audio interface using a Firewire 400 to 800 adapter then connected to a Firewire 800 to Thunderbolt adapter since the MBP doesn’t have a native Firewire port.  What I observed is that the Edirol was not getting power from the bus nor did the MBP (running Yosemite) recognize the Edriol.  At first I thought there was a problem with the Edirol since I haven’t used it in a while but when I connected it to an older MBP that has a native Firewire port, it worked normally.  Is there a known issue with these sorts of external audio interfaces working properly with newer MBP running Yosemite?  I’m hoping that a software update will fix this issue.

  • My Airport wireless is working for my two MacBook Pros and my daughter's iPod, but our iPad, Iphone and other iPod all say they need to set up an Airport Base Station but do not have the proper software.  I'm not sure what to do to remedy this situation.

    My Airport wireless is working for my two MacBook Pros and my daughter's iPod, but our iPad, Iphone and other iPod all say they need to set up an Airport Base Station but do not have the proper software.  I'm not sure what to do to remedy this situation.

    This might sound like a silly question, but are you sure the iOS devices (iPhone, iPad, iPod touch etc.) are still trying to connect to the same network from your own Airport router, as the MacBook Pros are? If you tap Settings on them, is the network name next to where it says Wi-Fi, the right one?
    I've got a weird feeling that either in the past couple of days, a neighbour got an Airport device and hasn't set it up yet (causing your iOS devices to try to help), or that perhaps there's an issue with your Airport router and they're noticing it and trying to help out, while for whatever reason, Airport Utility isn't opening itself on the MacBook Pros like it normally should if there's a problem.
    If you open Airport Utility on one of the MacBook Pros, does it report any problems with your Airport device, and can you view/edit the settings on it?

  • I started using LT 4 and I have a serial number, also upgraded to LT 5 and have a serial number. Now I just bought a new Macbook Pro and installed the LT 5, but it doesn't accept my serial number. Why?

    I started using LT 4 and I have a serial number, also upgraded to LT 5 and have a serial number. Now I just bought a new Macbook Pro and installed the LT 5, but it doesn't accept my serial number. Why?

    When you installed the Lightroom 5 on your MacBook, did it ask for both serial numbers. Since you purchased Lightroom 5 as an upgrade, you need both the serial number from your original purchase as well as the new serial number for Lightroom 5. If you have both of those numbers and they are still not being accepted then you will have to contact Adobe customer support for a solution.

  • I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. What can I do?

    I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. This happened once before and it was due to a buldging battery pressing on the track pad. I checked the battery and it appears to be fine. What can I do?

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in 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.
    *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
    Test while in safe mode. Same problem?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

  • Messages use to sync on MacBook Pro and iPad

    I use messages on my MacBook Pro and iPad mini with the same appleID and I receive the same identical messages to both devices. I don't know if it is a coincidence but I went away with both devices and they worked fine until my Mother's internet service stopped working at the end of our stay. When I got home and was able to reconnect with the internet, messages are mostly coming through again to my MacBook Pro but two of the senders are saying it shows the messages as undelivered, even though I get them all to the iPad and mostly none of them to the MacBook Pro. Seems to be only two senders are having this problem.
    I have repaired permissions and rebooted zapping my PRAM.
    Do you think it is them or me? Any other suggestions as to what I can try?

    I got one person to turn their iPad on and off and it is fine now. I think I started it though because of not having internet connection for several days! Thanks for your interest and help Linc.

  • My third party keyboard and mouse won't connect to my MacBook Pro

    I recently purchased an Insignia keyboard and mouse combo. I'm trying to connect them to my MacBook Pro and they refuse to respond. On the box and online it said that this combo was Mac compatible. I am running OSX 10.9.4.

    Sorry i should have mentioned that; i already have installed the drivers. I have the little boot camp console thingy and the display became to the right resolution after installing the drivers, so i know i have. Its something else, Windows based i think.

  • When Firefox last automatically updated, it suggested that Adobe reader needed updating, now, with Adobe Reader 8, I can no longer print from the internet, only to file. Help please.

    When Mozilla Firefox last automatically updated, it suggested that Adobe Reader needed updating. After updating to Adobe Reader 8, I can no longer print from the internet, only to a file. I know the printer and its interface must be OK because Word prints normally.

    Problem solved, it was my oversight, I had not removed the check from the Print to File box in the print set up.

  • Purchased aperture progam and downloaded onto desktop. recently purchased a macbook pro and want to transfer the program to new computer.  can it be done and how do I do it?

    I purchased the Aperture progam last year and downloaded to desk top Mac.  I now have a mac book pro and want to transfer the program.  Is it possible and How do I do it? 

    What is your Mac OS X version? And your Aperture Version?
    Did you buy from the App Store? When you downloaded Aperture from the App Store, you only need to sign into the App Store with the Apple ID you used to buy Aperture and to download it to your Mac Book Pro from the "Purchased" tab at the App Store. Your licence covers the installation on all your Macs for private purposes.
    If you bought a licence key from the Apple Store, not the App Store, copy the installer you downloaded to your Mac Book Pro and run it there. Then unlock Aperture with your licence key.

  • Using iMovie 11 in MacBook Pro and my photos are duplicating

    I am using iMovies 11 in MacBook Pro. I dragged photos from one particular event, now I am trying to drag a couple more photos into this same Movie Project from a different event, but every time I drag and drop, it is duplicating the very last photo that was originally there from the first event and only showing that last photo from the first event instead of the new photos I dragged in.  How can I correct this?
