WD My Passport drive works on old usb2 Macbook, but not on usb3 Macbook Pro Retina 13" Late 2013

I have a 1TB WD My Passport drive that will not mount in finder or even appear in Disk Utilities in OSX Mavericks 10.9.1. It does however appear in System Report under the USB heading as My Passport 0748, but shows 480mb/sec speed rather than USB3 speed.
It works on my old Macbook pro, which is a USB2 machine, perfectly well.
Has anyone found a workaround to this? I have looked high and low for a solution but none has nailed it. Could it be a problem specifically with the USB 3 driver in OSX? Or maybe even the drive itself?
Kind Regards
Phil

Here is my post on another Forum. My problem with the UI is now solved :
hi there,
same problem here. i had a mba 13" 2012 and wanted to switch to rmbp 13 because i need more real estate.
i sold the mba on ebay, but had a few days to compare my rmbp and mba side by side. both with exactly the same software configuration and OS Mavericks.
the mba was obviously snappier and i didn't know why.
after reading tons of threads, exchanging the rmbp one time and being frustrated i discovered this thread.
so i downloaded RDM, set the resolution to 1680x1050 (non-high-dpi!!!) and there it is, a snappy rmbp with mavericks.
(for me real estate is more import than a shiny retina thinggy, but also i don't see a bit difference between 1680 hiDPI and 1680 "normal")
i suspect the os isn't yet optimized, but i am far away from a software expert.
here is the link for RDM:

My flash drive works on a Mac mini, but not on a MacBook Pro. How do I get it to work?

Also, when I plug my phone into the computer using the USB drive, the computer does not recognize it. I have not tried my phone on the Mac Mini. They have both worked before on my MBP. What's the problem?

It may just not be configured to SHOW.
1. Finder>Preferences.
2. MISSING FROM DESKTOP: Make sure under "General" for "Show these devices on the desktop" that you have a CHECK mark under "hard disks" as well as "external disks" (if you have a dash that indicates specific items are set to hide and others are not)
3. MISSING FROM SIDEBAR: Check the same items under the "Sidebar" section if you are missing them from the Sidebar of Finder.

Script to connect and rename a drive works on Windows 8.1 but not Windows 7

I have a script to map a drive to a WebDAV share and the staff wanted it so the Drive shows up as Onedrive and not \\http......etc So I added entries to the script
to rename the drive to that. It seems to run and work perfectly on Windows 8.1 but on Win 7 it maps the drive but the rename part doesn't work. Even running the rename section manually in a separate script on Windows 7 does nothing. Is there a different rename
command for VB for a Win 7 OS?

WD Scorpio Black 750 GB works in my 08 Macbook but not my 09 Macbook Pro?, WD Scorpio Black 750 GB works in my 08 Macbook but not my 09 Macbook Pro?

Anyone know why the drive mentioned works fine but a little loud in my Macbook aluminum 13" but when I put in my Macbook Pro 15" I boot to the Apple logo and the spinning wheel spins for 10-15 minutes or more before I give up. I have re and re'd them twice with the same result. The 250 GB Hitachi drive that was in the MBP works in either one, it has snow leopard and the 750 has Lion on it, but I don't think that should matter?
I tried resseting the Pram and couldn't think of any thing else to do.
Thanks
R.

I don't think that should matter?
It depends on where the software came from.
If you had Snow Leopard installed and upgraded to Lion, the claim Apple makes is that you will then have a "Everybody" Lion, good for any Mac that can run Lion.
If you have a Mac that shipped with Lion, you have a "Custom" Lion, good only for that model of computers.
Does that help at all?

HT201758 Will a USB3 External Drive work in the USB2 port?

Will a USB3 External Drive work in the USB2 port?

Some do and some do not. You should read the technical information carefully to determine if it's USB 2.0 compatible.

I've ordered a new mac book pro 15" and i need to clean hard drive off my old PC...not really to move them to the mac, but just to save in case needed; mostly pics and office docs....any suggestions?

Buy an external USB hard drive and copy your data to it. Either that or burn them all to single or double layer DVDs (depending on amount of data you have). Or if it's really a small amount, consider putting it all on a USB memory stick.

IPod nano works with USB 1.1 but not USB 2.0

Anyone using an iPod nano that works with USB 1.1 but not with USB 2.0? I am using Windows XP and when installing the iPod software from CD it recognizes the iPod and am able to transfer songs using iTunes but when installing SP1 or SP2 to enable USB 2.0 transfers, Windows XP only recognizes the iPod nano as a USB Mass Storage Device. This is the same with iPod Updater.

I have a similar problem with the following configuration:
- Dell Dimension 4100 Desktop with 2 integrated USB 1.1 ports, Windows 2000 SP 4
- PCI 6-Ports USB 2.0 Card ("Mentor" resp. www.bona.com.tw), Model USB20-PCI/6P
What works well?
- All my USB add-ons (1.1 and 2.0) on the internal 1.1 ports as well as on the USB2.0 PCI card
- iPod Nano 4GB on internal 1.1 ports (external drive in windows 2000 as well as iPod in iTunes)
- iPod Nano works as well as on the USB 2.0 card ONLY WHEN my old 4-port USB1.1 hub is connected between Nano and USB card
What doesn't works?
My iPod Nano directly connected to the USB 2.0 card. Symptoms when connecting:
- Windows is very slow, process "scvhost.exe" or "system.exe" using 99% of CPU for some minutes
- iPod is recognised as external drive, but when I click on it, it is empty and copying files to it results in "I/O error"
- iTunes doesn't recognise the iPod (of course, if even windows itself cannot read from it...)
I removed all USB drivers, reinstalled iTunes, iPod (by the way, I still don't understand what "iPod update" is good for, except for updating the iPod's firmware), deactivate the internal USB1.1 ports, no result.

To anyone who has viewed this post and is having similar difficulties, the answer came on a different forum: I dragged & dropped the files from Mail to iCloud Drive. Opened them on my MB Air, they were saved in Templates and are now accessible across all my devices.

Safari (7.0.1) is non-responsive (spinning pinwheel) upon start up. It will work in temp user account but not in my main user acct. I tried reinstall via comman-r prompt on start up but the problem persists. Any suggestion for reinstall or repair?

Safari is non-responsive after intitial start up. Before it can load the homepage (google), it will hang and give a perpetual pinwheel until I force quit the program. Safari works in temporary user account but not in my primary user account. I have reinstalled osx via the command-r upon start up and the problem still persists. Any suggestions on how to reinstall or repair safari?

Thanks for thinking about my problem. I've already experimented with creating a new user, a co-administrator. The programs don't crash when that account is running, just as they don't crash when the guest-user's account runs. So it seems that the problem is limited to the default user's account, which is the one that was running when I installed the updates to the OS and the firmware. Another clue is that the programs that crash as soon as they are launched are *probably* the ones that were open at that time in that account. Yet deleting Saved Application States does not keep the programs from crashing when next launched.
So the mystery continues, but these additional facts will help with the diagnosis, I hope.
Thanks again for your suggestion.

Your basically calling/emailing yourself that's why your getting a busy signal.

I am working in a school. Last year we had one ipad cart (holding 30 ipads) with one macbook to work with. This year we purchased a second Ipad cart (another 30 ipads) but not the second macbook. Can I use this same macbook to sync all 60 ipads?

I am working in a school. Last year we had one ipad cart which holds 30 ipads and one macbook for syncing. This year we bought another cart of 30 ipads, but not an extra macbook. Can I sync all 60 ipads to the one macbook computer?

In theory everything that you are saying sounds right to me.
I am not sure at all what the limitations are when using the iPad in education as far as how many iPads can sync to one iTunes account. I am going to take a stab in the dark here and guess that you can sync up to 49 iPads with one Mac and one iTunes account since the device that I found has 49 ports. How's that for an obvious guess?
But seriously, I don't how Apple treats volume licensing with a single iTunes account in education. You were using 30 iPads this past school year so we know that's not a problem. The device that I found has 49 ports so we assume that 49 iPads are OK as well. You would have to check with Apple as to what the limitations/rules arefor using a single iTunes account.
There has to be a way to sync as many iPads as you have students in those classes or the iPad in education would not be a viable option. What I don't know about is how you go about paying for that volume license or how it is implemented.
For personal use, you can use up to 10 devices with a single Apple ID/iTunes account. No more than 5 of those devices can be computers.

On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion. They DO work on a lenovo machine but not my imac

On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion.
They DO work on a lenovo machine but not my iMac. reset Pram - no luck. took speakers from wife's desktop, they
do not work when jack plugged into my iMac - Sys Prefs "SOUND" only lists "internal speakers/ built in" as available options.
I used my altec lansing speakers on 3 macs including this one for 5-6 years.....now with Mountian Lion I can only get internal speakers???
Ideas? Any/All help would be greatly appreciated - been going nuts with this for 2 days now.

Hi,
When you start Messages fro the first time you are asked for an Apple ID
When this is verified and entered it appears in Messages Menu > Preference > Accounts and is Enabled.
The App should have also picked on on those iChat Accounst you had before.
These should be Enabled if they were when you last used iChat.
Exactly which "Accounts" are logged in can be seen in Message Menu > Accounts and will include the iMessage "Account" and Bonjour.
In the Window menu you will see CMD +0 for the Messages window and CMD+1 for the "Buddies" window which is a combined list at this stage.
Go to the Preferences > General Section and Untick the "Collect all accounts into one list".
This will give you separate iChat type Buddy lists.
You can check if that account/Buddy list is set to Invisible or if in the Preferences > Accounts > Security you have settings that will block some people from seeing you as On line.
You are saying Buddies can see you as On Line which implies they are still sending to your AIM based Names (@Mac.com is a valid AIM Screen Name)
I am not sure from your post if you are trying to iMessage their email IDs thinking they are Apple IDs and that they are using Messages as well.
There is no Buddy list for iMessages side
No-one can tell you are "On Line" until they have your details in the "To" spot in Messages with the correct iMessaged contact info (iPhone Number or Apple ID)
Obviously an Apple ID can be an email or look like one.
In some cases they are also valid AIM Screen Names as well.
In the case or the @mac.com name you may have linked this Apple ID to iMessages as well.

When i burn videos to a dvd-r disc it works on my macbook but not on a windows/pc or my dvd player. How can i make it work on all the above and not just a mac product?

Unfortunately, the recording & movie industry does not respect the rights of the people who make them money, and thus you can only use the paid-for content in ways they see fit. Even if I lived in a bunker where no one else could possibly see the movie I paid for, therefor I'm not 'sharing it illegally', I would still not be allowed in a blue moon to copy that movie to DVD for TV viewing. Someone will tell you to get an AppleTV. How about Apple give us one for free? Until this changes, people wanting to use their content in multiple locations will continue to download music & movies via torrents, legally or illegally.
