How can I create a new folder in an external disk that is connected via USB to my Mac?

How can I create a new folder in an external disk that is connected via USB to my Mac?

Just like you would create a new folder anywhere. Open the drive's icon from your desktop or the Finder, and click shift-command-N. (Or use the Finder menu if you prefer - File - New Folder).
If you can't create a folder, your drive may be the wrong format (you can't write to a Windows/NTFS formatted drive, for example). You'll have to back up any files you have on there, and then use Disk Utility to reformat it to Mac Extended (if it will only be used on a Mac) or MS-DOS format (if you want to share it with a PC).

I have MacAir with OS 10.8.4, how can I cancel the automatic link of my USB flashdisk to Mac instead of BootCamp, since I have one time press the ALT key before choosing "MAC" or "BOOTCAMP". Thanks

That only happens when you are running Windows in a Virtual Machine with OS X as the host. Shut down the VM and restart your Mac. Once the VM is running again and you insert a USB flash drive you should get that prompt again.

Mac mini core2 duo 10.7.2 not seeing files on usb external drives - mac formatted - ownership ignored- until finder refresh - any idea

finder has problems showing folders& files on external drives on mac mini with 10.7.2
this is affecting 2 external usb drives both mac formatted - ownership ignored
i click on the drive and see nothing
a refresh of the finder window will make the files appear
if i click on a disclosure arrow, the arrow turns down but no files are displayed
if i double click on the folder it opens that folder in an empty view - a refresh will bring the files visible
interestingly if i eject the drive and plug back it , it will usually display the contents of folders already visited last time but not folders i hadn't looked at - they require a refresh
programs such as iTunes can link to those files when they are not visible in finder
anyone else run into this - any suggestions
oh and drives seem to be working fine on my macbook pro with 10.7.3
cheers folks
Simon

John -I'm pretty sure it the mac mini thats having the issue
the two drives - each with their own cable - seem to work perfectly with my other mac
the mac mini is having no problem reading the files itunes and other programs access the files on the drives without a problem
its just the finder is not displaying the files without a refresh of the view
but thanks anyway

Is there an easier way to transfer your iTunes library on windows to a mac than copying the library to a usb and plugging the usb into the mac and put the library in the iTunes file

is there an easier way to transfer your iTunes library on windows to a mac than copying the library to a usb and plugging the usb into the mac and put the library in the iTunes file? I recently swapped to Mac and this is how i moved the library from windows to mac and library is in tact but is there an easier way? My cousin just imported her cd's again, but it was harder for me as i have an ipod with over 150 apps and i needed to move them. i think it would be helpful if i knew of an easier way so i can help a friend move his. Thanks

The general method of use is to download a script (double-click or right-click and use Download or Save As...) to a folder of your choice, e.g. your Desktop, Downloads folder or create a folder at ...\iTunes\Scripts. Select a playlist or highlight some tracks in iTunes and then double-click on the script to execute it. If no specific tracks are selected the script will try to work with all tracks in the current playlist or sometimes the entire library.

How to install USB card in Mac OS 8.6?

Recently, i buy a new printer. the printer only can use USB connection. My MAC is MAC 8500/1800. It is no USB port. i added a USB card. But it is not work. I find information on internet. It need installed a software(USBSupport1.4.1smi.bin). I downloaded the software. But it can not open. i hope some people can help to solve the problem.
Thank you very much for your help.

Hello tytom2003,
Welcome, and Happy New Year!
First, make sure your printer and USB card are Mac compatible.
Second, you will probably have to re-install your Operating System in order for your Mac to "see" your USB card. You cannot install the proper USB and USB support extensions by downloading them, because your Operating System will not "see" them, will not recognise them.
You should perform a "clean reinstall" (also known as "archive and install") from your original installation CD - or from a retail, full install CD, with the USB card installed in its PCI slot. Your Mac will now automatically "see" or recognise the USB card, and will see the need to install the USB extensions.
By doing a "clean install", you will have a newly installed System Folder and the old, disabled 'Previous System Folder' next to it. You will not lose anything, as all your old applications and documents will be saved in the 'Previous System Folder' where you may retrieve them and drag them over to your new System Folder.
I assume you are running OS 8.6, but it doesn't really matter. The OS CD will install the correct USB extensions. (An OS9 CD might install 1.4.6 extensions - whatever it installs should work).
I did not have your exact model, but rather a 7300 and several beige G3s, but the procedure is all the same.
It is also possible to do a 'Custom Install' or install by 'Tome Viewer' utility.
Let us know if it works.
I hope to have been of some help. It will have been an honour.

I was wondering if there is a way to shut off the install mode on my G3 every time I plug in the USB to my Mac. I have an android manager software Mobile Go that this seems to be preventing it from connecting

as62467 We appreciate your G3 question! Let's see how we can help. What you are able to adjust is the USB connection mode by going to the home screen and selecting'recent apps' (in the touch keys bar), settings,storage, the menu (the 3 tiny dots) and tap usb pc connection. If you do not want the software to try and install choose either the internet connection or camera option. Let us know if this helps.

Musicord Cherub MRD-41 Recorder: USB-Driver for Mac

Hello,
I am searching for the USB-Driver for Musicord Cherub MRD-41 Recorder. Searching for it along the internet did not give any matching result.
Originally a CD containing the USB-Driver for Windows was included with the product. Since we now work with Apple-Products this does no longer work. Connecting the device to a Mac (as it is normal these days) and hoping, that it will work without any additional Software does not give any result.
On the Original-CD the manufacturer states, that the USB-Driver for Mac can be downloaded at www.apple.com but there nothing can be found anymore.
The recorder has been bought about 6 years ago (used under Windows then). Now we would like to use it again under Mac-systems (10.6 and 10.7).
Does anyone know, if, and where help can be found?
Thank you very much

If it uses MIDI, Garageband can often read it.

When I connect my iPad with usb to my mac the iPad gives me a "blinking" message asking to trust the computer. Problem is it does not give me enough time to select yes. What am I doing wrong? Help!

When I connect my iPad with usb to my mac the iPad gives me a "blinking" message asking to trust the computer. Problem is it does not give me enough time to select yes. What am I doing wrong? Help!

Everything that you sync to the iPad is done through iTunes or from downloading from the cloud if they are iTunes purchases or through iTunes Match, if subscribed.
It is also not possible to transfer music or certain other files though Bluetooth between other iPhones or Android devices. You can transfer between iOS devices, pictures through devices that are Airdrop capable.

How to make linux bootable off a usb stick on mac

Guys i was wondering how to make linux bootable off a usb stick on mac, since i dont have a optical drive in my mac, plus i need it for university

I have the same question, but parsed differently. What people have tried answering here is:
how to (make linux (bootable off a usb stick on mac))
What I'm trying to find is:
how to make ((linux bootable off a usb stick) on mac)
That is, I don't want to boot from the usb stick on my mac; I want to write an ISO to a usb stick that's plugged into my Macbook Pro (Mavericks), then carry the stick to a different machine (several discarded Windows boxes in fact), plug it in there, and watch it boot on that machine. I've done a bit of googling, but everything I find talks about making USB drives with content that can be booted on a Mac. What I'm wondering is if it's possible to write to use my Mac to write bootable USB gadgets that work on other machines that aren't running OSX software.
Anyone know if this is discussed anywhere? If not, what's the right forum to ask it on? And how do I ask it so that I don't get yet another explanation of how to make something that will boot on my Mac?
I have several linux ISOs waiting. Actually, I could do the job on one of several available linux boxes. But I'd like to do it on my portable laptop, which at the moment is this Macbook Pro.

Need help on USB hub for mac air 13 inch (2 external hardisk and Iphone)

Hello everyone, I am a new macbook air user, and currently using 2 external hardisk of 1TB and 2TB. I am looking for usb hub that support both of my external hardisk, ethernet and iphone too. The problem is, limited usb hub for mac air and bad review on balkin product, any advice for me?
One more thing, I just moved from window to mac for the first time, and bought Western Digital 2TB external hardisk, the problem is, I can't save any video/audio file that I downloaded from internet in macbook to be transfer/move to this WD 2TB external hardisk, except for back up and time machine. It refuse to except any file that I try to move in to the external hardisk Can anyone help me? compactibility problem?

First, I have not found any of my hubs to have an issue with my MBA. Just make sure that if any peripherals you attached to the hub are adequately powered. Either by having the hub independently powered, or the devices having their own power supply.
The drive problem you have may be due to the file formatting. If this drive is formatted NTFS, then in many cases you can write to it using a network protocol, but OS X can't write to it if attached directly to the computer, e.g. USB, SATA, FireWire. You will neeed to either format the drive as a HFS+ drive, or use software that enables OS X to write directly to t a NTFS formatted drive, such as NTFS-3G. DISCLAIMER: As the information you provide for your circumstances is limited, this is but one suggestion amongst many, that explain your situation.

Problema con USB en formato mac os plus

Hola, el problema que tengo es que he formateado un usb a formato mac os plus con registro encriptado y no me acuerdo de la clave.
La clave la generó el generador de contraseñas de mac osx.
He probado intentar formatearlo, pero no puedo formatearlo porque aparece en la utilidad de discos bloqueado.

Lamentablemente, una vez se le olvida la contraseña de una imagen con formato Utilidad de Discos, que son básicamente de suerte.
Unfortunately once you forget the password on a Disk Utility formatted image, you are basically out of luck.

Comment connecter une table de mixage usb a mon mac book pro

comment connecter une table de mixage usb a mon mac book pro

Bonjour ..
1-Je voudrais avoir mes apps achetees sur mon iphone 4gs, aussi sur mon mac book pro.
Las aplicaciones que se ejecutan en el iPhone no se puede ejecutar en Mac OS X. Se trata de dos Sytems operativos diferentes.
2-Je voudrais pouvoir controler idealemente mes depenses de argent pour les achats sur appstore sur mon iphone mais je ne trouve pas comment le faire car il me montra la liste des app grauites et payant sans distinction.
Autant que je sache, il n'y a pas de applications disponibles pour le faire.
Apres j ai trouve un petit programe que c est appel App Store Expenses Monitor mais je n arrive pas a le faire marcher.
Ce soft est conçu pour les achats iTunes seulement. Pas pour le Mac App Store pour le Mac OS X.
La meilleure façon de garder trace de vos dépenses et iTunes Mac App Store est de vérifier l'historique des paiements sur une base opportune.
Lancez iTunes. Sélectionnez iTunes Store dans la liste des sources sur la gauche, puis cliquez sur Se connecter sur le côté droit de la fenêtre iTunes.
Dans la fenêtre Informations sur le compte cliquez sur Afficher tout pour le droit de l'historique des achats.
