Flash drive no longer works with MacBook Pro. Now says it is unformatted, but no info what to do and not lose my data. Does not show up despite multiple prior uses on the same computer.

Upgraded to OS Mavericks in November. Flash drive that worked fine previously with Lion and worked several times with Mavericks. Now says the 8GB jump drive (Lexar) is unformatted. Disk Utility First Aid seem unavailable. It sees the drive, but on the far left left, and when highlighted, nothing can be done with it.
How do I recover my information or reformat it without losing my data?

I am MikeMacBP2013. Cannot figure how to reply to Kappy's comment. Kappy, your comment did not really help me. My concern is how to save my data, not wipe and use a $10 USB drive.
In the past two hours, I wasted most of it trying to use a software program, Disk Drill by Cleverfiles, that offers a "free" version. The free version does not recover your data for you. It is not a free 30 day trial. It is deceptively advetised - it will recover data but you will not see your data untless you pay them almost $100.
Instead of trying to recover the data on the USB drive, this program ran a recovery on my computer hard drive and any disk image it could find on my computer until I stopped and deleted it. Apparently, it collects and keeps data recovered locked unless you pay for a key to download your data. This is not clearly presented up front. Had I known, I would never have put their software on my computer.
I need direction to a reliable recovery program that is not this sneaky and deceptive. I stopped it when I discovered it was not doing what I had clicked for it to do, and removed the software.
I am looking for a recommendation for a program that will do what Apple Disk Utility does not do - restore the formatting that may have been corrupted, or at least recover my data files so I can put them on other portable media.
I recently installed a CalDigit Thunderbolt Dock to get USB 3.0 on my early 2011 Mac. I suspect this may have contributed to this disk failure but will have to contact their tech support tomorrow.
Thanks for any suggestions for a reliable free or reasonably priced recovery software that someone can attest from using really works.

6/9/11 update old usb keyboard no longer works with macbook pro

Hi I have been using my old Imac usb keyboard with my macbook pro at work since I got my macbook pro. But as of yesterday I have not been able to use it anymore. Any suggestions to a fix or do I have to buy a newer keyboard? I need the numbers pad to entering data.
Any suggestions would b great.

Your message would be easier to decode if you had proofread it before posting.
Does your keyboard work when the mouse is plugged directly into the computer instead of into the keyboard, or does the keyboard not work at all? If not at all, then it sounds as though you're right in guessing that the keyboard isn't getting power for some reason (bad cable? bad connection inside the KB? USB port on computer shut down?) If the KB works when the mouse isn't plugged into it, then the mouse and KB together are demanding more power than the computer's USB port can supply, and neither is getting what it needs when the mouse is connected to the KB. In that case, plug the mouse directly into the computer to use it.
The USB port in your keyboard probably doesn't put out enough power for the mouse you are using. This is typical of older keyboards, which were designed to power old-style electromechanical mice rather than the laser mice that are commonplace today.

Dell p2815q no longer working with Macbook Pro A1398

Hi,
Some time ago I bought a dell p2815q monitor. It would work just fine using the display port to thunderbolt connector.
After some time my Mac Pro simply stopped picking it up. When I connect it, it seems like it tries to display on it but it blinks every couple of seconds and no input is detected on the monitor.
I've checked that the connector is fine, it simply works with other monitors and have also tried doing a PRAM reset.
I also checked the display itself and it works like a charm with other non Mac laptops.
This is becoming very annoying and need to find a solution to the problem. I am running Yosemite 10.10.1.

Hi, I got the same monitor the other day and there should be no problem getting it to work.
Use the DP to mini-DP cable supplied with the monitor.
Make sure this cable is plugged into the correct input DP port in the back of the monitor (not the DP port for daisychaining).
Make sure the DP input is selected in the inputs menu on screen.
Plug mini-DP end of the cable into Mac
Should work ...

Does the Apple remote control work with MacBook Pro with retina? If yes, how can I sync it?

Does the Apple remote control work with MacBook Pro with retina? If yes, how can I sync it?
Thanks!

It should. First, turn on BlueTooth on the computer. In BT preferences be sure to check the option to look for all devices. Your remote should be picked up and a notice asking if you want to Pair it with the computer. Select Yes. Once it is paired it can be used to control your computer.

Does Adobe Photoshop Elements work with MacBook Pro with Retina display?

Does Adobe Photoshop Elements work with MacBook Pro with Retina display, please?
Have searched Adobe website for answer - most recent is 2013 answer, saying no.
Contradicted by a staff ember who only referred to Photoshop, not Elements.
Reason I need it is that iPhoto does not support very high resolution photos - which I have now scanned onto my MacBook and do not want to re-scan!! After 90 minutes at my local Genius bar (lovely folk, very conscientiously searching for an answer...), re-scanning was their final piece of advice.
Help, please...

Hello Smis,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand you are having issues with your HP Monitor on your MAC. I am providing you with an HP Support document: Updating a Monitor Driver, where it states under the sub-heading Using HP monitors on a Mac "HP monitors are not supported in a Mac environment. However, newer Macs use graphics with VESA modes and can display to most HP LCD monitors. To do this, connect the monitor to the Mac while the Mac is off, and then turn on the MAC. The monitor should operate at 60Hz. The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment."
This being said all I can advise is that you check to see that the monitor is set to operat at 60Hz and contact Apple for assistance if that does not get your monitor displaying correctly.
I hope I have answered your question to your satisfaction. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro when plugged in with a dvi to mini dvi cable. Any ideas what to do to make it work? I lugged the 23" 2500 miles into the wilderness and I need help

Okay, here's an update: the DVI to ADC adapter does work with the Apple displays that I have tried, but it won't work with the Formac. I have tried multiple time to contact them, but to no avail... they don't even respond to threats of posting my opinion of them, which is this:
DON'T BUY ANYTHING FROM FORMAC! They make quality products, but their customer service is a big time joke! They won't take care of you.

MacBook Air Superdrive?? Does it work with MacBook Pro

Hello,
I need an external Superdrive. Does the MacBook Air Superdrive work with MacBook Pro??

No, it does not (at least, not without opening the drive and modifying the internal components).
External optical drives from Sony and LaCie work well with the MBP. Here's ONE EXAMPLE, here's ANOTHER EXAMPLE, both from Amazon.

Does 'Network Connect' work with MacBook Pro?

My safari unexpectedly quits when attempting to log into my company's VPN.
- I log into our VPN website and the connection begins to initialize
- with my MacBook, Safari (2.0.3) unexpectedly quits
- with my PowerBook, 'Network Connect' automatically starts and the VPN connection completes without any problem
Does 'Network Connect' work with MacBook Pro? Any ideas?

Resolved. MacBook Pro was having trouble dowloading the 'Network Connect' application when I logged into my VPN client for the first time. I copied it from my PowerBook G4 over to the appropriate folder and it now works perfectly.

Generally signing out and signing in (signing out and back into the Creative Cloud application ) will fix this. If it isn't resolving the issue for you, let us know what you see and we can try something else.

According to their site, they offer no drivers for Mac, or mention anything about Apple.
I would say no.

Is there a conflict between Reader XI and Acrobat being used on the same computer?

I downloaded the new Abode Reader XI. The computer in question has, also, Adobe Acrobat 7. Is there a conflict between them if used on the same computer? I can not open any PDFs and now the saved PDFs I had on the computer will not open and the icon shown on the desktop is gone. Please advise as I scan documents to this computer all the time and the person who needs to see them can not.

I have Acrobat 8.1.6 and Reader XI on Win XP. Do these conflict? Should I get rid of the newer Reader?
I'm having problems printing to the PDF print driver, locks up system, shows printer offline in spooler. I doubt problem is with driver itself because I can print a Test Page from it ok. But printing to Adobe PDF from Word & other apps locks up & never completes.
There's an Exclamation Point next to Acrotray in Explorer. (see image) What does this mean??
Have tried Repair install of Acrobat twice.

Multiple iTunes Accounts on the Same Computer

iTunes states that you can have multiple iTunes accounts on the same computer. But when I attempt to put in a new user account (for my wife so she can have her own music library) my own iTunes account pops up when I go to load iTunes while in her user account. And if I create any account that is NOT an 'Admistrator' account iTunes refuses to install itself as the "user does not have the privileges - consult your Administrator". So I am lost as to what I need to do to create separate iTunes accounts where each person has their own iTunes library and thus their own music. Perplexed...

M Parker,
Yes, since you are trying to keep things separate, that is exactly what you would do.

Macbook pro now says itunes not supported on this type of Mac. only change has been addition of Apple TV. how to fix?

My older macbook pro now says itunes not supported "on this type of Mac". Only change has been addition of Apple TV. The Apple TV remote is also controlling the Macbook. Is this the problem? How to fix?

Did you recently update OS X? The icon indicates you have a version of iTunes that is not compatible with the version of OS X you now have installed. The current version is Apple iTunes 11.0.2, and it's compatible with 10.6.8.
