"dd: /dev/disk4: Permission denied" error when making LiveUSB on Mac OS X

I'm going through the steps: "How to create a bootable USB stick on OS X" to install Ubuntu on a USB stick, and I keep getting the error:

dd: /dev/disk4: Permission denied

when I try to run step 8.

I know this is probably a silly little mistake, but I'm not familiar enough with the terminal to figure it out on my own. Anyone out there who could help? (I'm using OSX, by the way.)

Is there any program that can open files from Sketch

Sketch is an app that's Mac OSX only.

Its used for UI design and my company uses it. I can't run the app in Ubuntu.

Is there any program for Ubuntu that can view these kind of file collections?

It's basically a folder with a .sketch ending containing a "Data" file with no ending and some other stuff.

What's the best filesystem to share between OS X and Ubuntu?

Got a MacBook Air 3,1 11" w/ 128GB SSD. Configuring for dual boot. I intend to have a shared drive where I'll store my media. What filesystem is best?

They say FAT32 is best for cross-platform compatibility, but the maximum size for file transfer is 4GB, which could be an issue for my media transfer.

Wubi Install for Mac OS X

I just installed Ubuntu 10.10 on my Windows 7 box using Wubi and I'm loving it so far. One feature that I love is the fact that because I used Wubi it doesn't seem to create a separate partition. Through what I can only imagine is some VM magic Windows and Ubuntu live together on the same hard drive without a partition and you can even access Windows files from within Ubuntu and visa versa. I also have a MacBook and I would love to be able to install Ubuntu on the MacBook as well but I don't want to surrender a portion of my disk space to a different operating system. Is there currently a way to do the whole Wubi VM "virtual partition" on a Mac?

Can Mac OS applications run natively?

This may be a silly question, but since the newer Mac systems are built on unix, is it possible to run a Mac app natively on Ubuntu? I'm specifically interested in the Coda development environment.

VirtualBox - How to install OS X guest under Ubuntu host? [closed]

Has anyone managed to install OS X Guest in VirtualBox under Ubuntu? I've wasted 3 days trying to accomplish this by following various tutorials around the Web, but none seem to work for me.

Can anyone share some experience, or an updated tutorial link for this? For the record, I'm running Ubuntu 13.04 on Acer AS5830TG.

How do I disable visual effects in Ubuntu 12.04.1?

So I finally managed to install Ubuntu 12.04.1 on my G5 iMac but I don't want any fancy visual effects. How do I disable those? My user logs in automatically and I can't find anything in System Settings, there is no visual effects tab inside the appearance applet.

I would like to keep the nice Unity shell but just disable visual effects so that the Quartz part of my video card doesn't get used.

Thanks!

What are the differences between Mac OS and Linux? [closed]

What are the major technical differences between Apple's OS X and Linux? I understand Mac and Linux both have a similar architecture, so what are the major differences that prevent for example, mac applications being compatible with linux?

Can I run OSX applications?

Just wondering, are there any projects like WINE, but for Mac software? That is, can we use a program that acts like a compatibility layer to run Mac apps?

How do I get a larger screen resolution in VirtualBox on Mac OS X?

I am running the new Mac Air 13" with OS X 10.8.2. I then downloaded the latest VirtualBox 4.2.6. Then, I installed Ubuntu 10.04 into the VM.

First off, after I installed the VirtualBox Guest Additions and restarted the VM, the Ubuntu desktop froze after the GDM login and I had to delete the VBoxGuestAdditions folders out of /opt and /usr/lib to get back to normal again.

Second, I go to Ubuntu's System > Preferences > Monitors and try to change the settings, and there's nothing higher than 800x600. I then tried the VirtualBox various View menu settings and tried again in Ubuntu's System > Preferences > Monitors and I'm still stuck.

How to mount HFS+ drive and ignore permissions

I installed Ubuntu and Windows on my MacBook and Ubuntu is my primary OS; however, all of my media stays on my OSX partition. I want to be able to access it (at least my OSX user's home folder) from Ubuntu without having to launch a media player (or anything else) as root. Also, because I occasionally want to fire up my machine in OSX, I don't want to change anything that I would need to change back frequently (I read a lot about changing UID--I don't exactly understand what this entails, but I wouldn't want to have to change my UID back and forth depending on which OS I'm using. Similarly, I don't want to change file system permissions back and forth).

Also, I saw something about a "noowner" option, but that doesn't seem to do what I want it to.

So I guess I'd like to be able to do something like this:

sudo mount -t hfsplus -o noowner /dev/sda2/ /media/Mac

And then be able to access all of my media (at least everything in my OSX user's Home folder) without dropping in as root. (for clarity: the above command line entry doesn't do what I want it to do, but I want to be able to do something similar).

Or would it be better to change my UID? And if so, how?
