I am having problems on mounting my NTFS formatted drive on my MaC PC. But after upgrading to OS X Lion, I can no longer mount my drives. It works well before but after the recent upgrade, I was unable to. The Disk Utility can read my formatted driveS but it won't let me mount them. I am using MacBook Air with Nvidia GeForce 320M running Mac OS X Lion 10.7. How can I fix this?


NTFS-3G could not mount /dev/disk1s1 at /Volumes/LaCie because the following problem occurred:

Did not receive a signal within 15.000000 seconds.

Normally, when I am taking a screenshot on my Mac PC, I just use the Command + Shift + 4 method and it works fine. But now, when doing that process, an error showed up stating that I cannot save my screenshot. I never change anything on my computer nor installed anything that might be interfering. I tried to restart and make a screenshot again but it still failed. Why am I having an issue with the saving location? How can I fix this?

Your screen shot can't be saved.

You don't have permission to save the files in the location where screen shots are stored.

I just downloaded the Disk Image File (DMG) of GUIMiner which I will be using on my Mac OS X. However, it crashed when I attempted to launch it and it shows an error. I am getting confused since the error message has no error codes or whatsoever. I think I have re-downloaded the dmg file for few times now and  still trying to launch it but it still failed. Has anyone have an idea on what the error means? If so, please help me fix it. Thanks a lot in advance!

Here is the image of the error I've got:

I'm running Mac OS X Mountain Lion. I am getting a kernel panic error when I restarted my computer. As far as I remember, I shut it down properly the last time I used it without any issues. But when I opened it today, it has an error. And then when it restarted, the same error will just showed up. How can I fix this?

You shut down your computer because of a problem.

If you want to open the applications that were open when you shut down, click Open.

If you do nothing, the computer will continue the login in 56 seconds.
