Needs mac driver for hp 450c to print from macbook Pro

Usually I shift-click the items I want deleted. They will be highlighted and then you can hit the delete key on your mac.

The DVD works by just pushing it in far enough till you get resistance, then the drive pulls the DVD in by itself. If after it pulls the DVD in, it just ejects it, The DVD drive thinks you are using an incompatible disk.

You can also try resetting the SMC.
This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

sad mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,

Hi, I also had this problem on macbook air 2011, I tried everything but all failed. However, once I used up all its battery and left it like that for 2 days. After that, everything turned back to normal, the shift key worked normally again. Hope this will help you.

I don't think there are any drivers for this printer to work on a Mac, sorry.

Click on this link, then choose the link where you need assistance: http://bit.ly/ah2wyd

are you printing through another PC (print sharing) on the network? If so you need to install the Mac driver also, not sure how to tell you to do that, but is most likely the problem

Give this driver a try.

The drivers for XP are on the official OS X Leopard DVD. Install this when running XP and then run the Apple Drivers Set up on the disk.

Normally I would say use BlueTooth, but the i930 does not have Bluetooth.

I would look into using this software - http://www.pocketmac.net/products/devices/motorola_i930.html

Try downloading GutenPrint 5.1.4 It is a collection of open source printer drivers. Based on reviews and comments, it seems to have worked with older printers.
