Cannot use mac os.

Whenever I turn on my mac, I click on windows and I can use the system operating windows very well, but when I try to use the mac operating system my computer just stops. How can I fix?

Hi KF207,

I understand that you are not able to boot your Mac in OS X after installing Windows with Bootcamp.  The resources below will provide some steps of troubleshooting for this issue:

How to choose a disk to boot your Mac.

Follow these steps to choose a boot with the Boot Manager floppy:

  1. Turn on or restart your Mac.
  2. Immediately press on and hold the Option key. After a few seconds, the Boot Manager appears. If you don't see the volume that you want to use, wait a few moments for the Boot Manager to complete the connected scanning readers.
  3. Use your mouse or trackpad or the arrow keys left and right to select the volume that you want to use.
  4. Double-click or press the return key to start up your Mac from the selected volume.

Restart in OS X Boot Camp

If you started your Mac in Windows using Boot Camp, you can use the Boot Camp system tray to switch back to your default startup disk to OS X.

  1. In Windows, click the Boot Camp icon in the system tray.
  2. In the menu that appears, Select reboot into OS X.

Booting from OS X recovery

You can also start your Mac OS X recovery or recovery of the Internet if your Mac was manufactured after 2011.

To start your Mac by the recovery system, use these steps:

  1. Start or restart your computer.
  2. Press the command and R on your keyboard until you see the Apple logo appears on the screen.

Take care

    and I can't tell if it's a configuration issue with vmware or a configuration problem in Ubuntu (or more likely, both).

    The mouse worked - but when I installed a window manager and improved, it seems to stop working.

  • How can I contact adobe to disable my photoshop? cannot use my old computer

    question as above, my computer was broken yesterday and I have to activate my photoshop on the new computer, cannot use the serial number since it was activated on the old computer

    Shatyou72,

    You can install and activate the perpetual software (purchased) two computers on the same platform (mac or pc), as long as you don't use it on a facility at the same time.

    If must not already be used the software on the first computer, deactivate the license on this computer - How to disable the software.  This allows it to be installed on another computer to any.

    If you no longer have access to the computer and your software is still supported, you can ask the Support from Adobe that allows you to disable the software. Have your serial number or Adobe ID ready, then contact us.

  • guest computer must have access to the printer host cannot use

    I have a new Mac, an old Mac, an old Windows machine and printer of Xante AW1200.

    Almost all of my work is done on the new Mac.  I get the old machine Mac or Windows of the drawer on rare occasions, or when I need to print something, because the new Mac cannot use the printer.  (Xante never taken the trouble to develop an OS X 10.6.4 driver for this printer.)

    I would like to get rid of the Windows machine.  I have it successfully migrated to a machine of comments on the new Mac, using vmware Fusion 3.1.3 but I have not found a way to get the computer to see the printer.

    This isn't a complete surprise, as Xante does not provide a driver for their (former) printer and (my new host) operating system OS X 10.6.4 - but they were planning a WIndows XP driver that has always worked well on the Windows machine, connected by the RS232 port.

    The printer also works very well on my old Mac, connected via ethernet.

    Can I connect the printer to the new Mac's ethernet port.  Of course, the Mac cannot work with it.  But could the guest computer use Windows sound driver to manage the printer?

    None of the four standard ways of printing seem applicable: ThinPrint because the host cannot use the printer.  USB because the printer is not a USB connector.  network / wireless because I do not have my old Mac running all the time.  Hello because I think that it requires that the host can see the printer.

    It certainly isn't a frequently asked Question.  Sorry, my situation is so unusual.  But the printer is special enough for the work that I do.  Any tips?

    Thank you.

    If you have a router on your site then you should be able to connect the printer to the router, configure it as needed, and then accessing it in the comments as a network printer.  Note: The guest network should be configured as connected by a bridge to access in this way.

    Another option of network which is doable, but a little more difficult to set up, is to fix the printer directly on the Mac with a standard CAT5 Ethernet cable, not a Crossover as suggested in the Ethernet Port of Mac being automatic detection User Guide.  You would then manually configure the IP address, etc. on the printer and network bridged on the comments and even if Bridged his only access to the printer on this network adapter.  Then use a second network in the guest configured as NAT, if you do not also use Bridged on that, to enable the client to have access to other resources on the physical LAN to the host, such as Internet access, etc..
