Mac wont recognize external usb HD anymore.

Hello all,
I have an external seagate HD that I formatted on my mac which worked on both pc and mac fine. Suddenly my mac wont pick it up when I plug it in. The pc still does. Was this after the update? SO, I re-formatted on pc to ntfs and still no go. ANy help please on how to gain access to it on mac with only communication being with pc. Thanks!

Try a simple SMC reset:
Reset the SMC (for MacBook, MacBook Pro and MacBook Air models with internal batteries):
1. shut down the MAC
2. Plug in the MacSafe adapter (i.e.power cord/charger)
3. PRESS AND HOLD SHIFT+CONTROL+OPTION+POWER buttons at the same time
4. Release all keys and buttons simultaneously
5. press the power button to turn on your mac as usual

Mac wont recognize iphone

I plug my iphone into my macbook pro and it charges but my mac wont recognize it and sync in itunes. It also does not show up in finder. I know its not my iphone or the cord because I tried on my friends computer and it worked.

Are you running the current iTunes version (11.0.1)?
If you are, then this should help:

Installed new pages 5 but my mac wont recognize it.

I installed the new pages 5 but my mac wont recognize it. It says it is downloaded and installed but not operating...anyt houghts?

You have 2 versions of Pages on your Mac.
Pages 5 is in your Applications folder.
Pages '09/'08 is in your Applications/iWork folder.
You are alternately opening the wrong versions.
Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
Pages 5/5.01 can not open Pages 5.1 files and you will get the warning that you need a newer version.
Pages 5.1 sometimes can not open its own files and you will get the warning that you need a newer version.
Pages 5 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
Once opened and saved in Pages 5.1 the Pages 5 files can not be opened in Pages 5.
Anything that is saved to iCloud is also converted to Pages 5 files.
All Pages files no matter what version and incompatibility have the same extension .pages.
Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
Apple has not only managed to confuse all its users, but also itself.
Note: Apple has removed over 95 features from Pages 5 and added many bugs:

Archive/trash Pages 5, after exporting all Pages 5 files to Pages '09 or Word .docx, and rate/review it in the App Store, then get back to work.

USB wont recognize external drive

I see that there have been a lot of problems with the usb ports recognizing external hard drives. Some of the fixes are so confusing, I cant even follow them! Does anyone have an easy fix for this problem or do you think apple care will know? i have used this drive for about a6 months with no problem, and then all of a sudden my Imac wont recognize the drive.

HI
You should check in System Profiler, under the USB section to see if the drive appears there (Apple -> About This Mac -> More Info -> USB)
Also, try resetting the SMC & PRAM to see if that helps

Macbook does not recognize external USB drive - except when booting with CD

Hi all,
I recently swapped my Macbook's internal HD (Toshiba 100gb 5400 rpm) into an external USB enclosure (Eagle Consus). The computer does not recognize the external HD, even when using two USB cables for extra power. No luck with safe mode or resetting PRAM. Disk utility just hangs with spinning wheel if I start it. Switching the USB ports does not help.
I thought it might be a power problem until I noted the following:
1)The external drive works fine if I boot the Macbook from the Mac OS install CD... with this I can run disk utility and scan the drive with no problem
2)It works fine on an old Mac Mini with only ONE of the USB connectors plugged in
3)The enclosure worked fine on the Macbook when I had the new drive in it (320 GB 7200 RPM) while copying the files over
Any thoughts?
Many thanks,
--T

It is actually using a power supply, yet it will not actually power on unless it is connected to a computer's USB port. At least this is how it works on my old desktop running Windows 2000. When you disconnect the drive from Windows, or put the machine in hibernate mode, the device actually shuts down. It powers back up once the machine wakes up from hibernate mode.
It's a somewhat older device which predates the Macbook Pro, but it claims to support older Mac, such as the G3, G4, G5, iMac, iBook. OSX 10.0.4. So perhaps it's just too old?
It's a Buffalo HD-HB250U2 (250 GB).
So you're in Japan too?

How to install Firefox for Mac on an external USB 3.0 drive and run Firefox portable?

I recently acquired a new MacBook Pro 10.9 Mavericks laptop and, I would like to to install Firefox for Mac on a Mac-compatible external USB 3.0 HD, and import my 16MB of legacy bookmarks from a PC-compatible USB 2.0 HD and, run Firefox as a portable application, as I did for years on my 7-year-old EOS'd Dell Inspiron XP laptop.
Do-able?
If so, I would like to do the same with Thunderbird...

Hi,
There are portable versions of Firefox and Thunderbird but Mozilla doesn't offer them directly. You can get them from PA.com. Links are below:
*[http://portableapps.com/apps/internet/firefox_portable Firefox 28.0]
*[http://portableapps.com/apps/internet/thunderbird_portable Thunderbird 24.4.0]
All you have to do is open it, and point the installation directory to your USB Stick

The five Rs are documented here
http://www.apple.com/support/ipod/five_rs/ipod5gen/
or here is a copy of the restore instructions
For Mac:
1. Make sure you've reinstalled the latest version of iTunes.
2. Open iTunes, and then connect your iPod to your computer.
3. After a few moments, it will appear in the source list in iTunes.
4. Select your iPod in the source list and you will see information about it appear in the Summary tab of the main iTunes windows.
5. Click the Restore button. You will be prompted with one or more restore options that may prompt iTunes to automatically download of the latest iPod Software. The 4 possible restore options are:
Restore Option 1: Restore - Restores with same iPod Software version already on iPod.
Restore Option 2: Use Same Version - Restores with same iPod Software version already on iPod, even though a newer version is available.
Restore Option 3: Use Newest Version - Restores with latest iPod Software version on your computer.
Restore Option 4: Restore and Update - Restores with latest iPod Software version on your computer.
6. A message will appear prompting you to enter an administrator's name and password.
7. A progress bar will appear on the computer screen indicating that the first stage of the restore process has started. When this stage is completed, iTunes will instruct you to leave iPod connected to your computer to complete restore.
8. During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage. Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.
9. After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.

Booting the Mac from an external USB drive

I was under the impression that you could only boot a Mac from an external firewire drive. However, I have just successfully booted my new MacBook from an external SuperDuper backup connected via USB.

That basically only applies to Mac OS X on PowerPC Macs, not on an Intel Mac such as a MacBook.

MBP Does Not Recognize External USB Devices

MBP does not "see" external USB devices (such as Garmin Nuvi GPS) or any thumb drive. No external USB devices show up in Finder nor does Disk Utility see them. No cable issues. Have tried restarting several times, but to no avail. This MBP used to recognize these USB devices, but no longer do so.
I have seen this question posed several times in forum, but no suitable answer. Don't know if it is H/W or S/W problem.

Hi Terry Temple
Is there at least any power going to the USB ports? ( as in if for example you plug in a USB light, will it switch on? )
If there is power in the USB ports it might be a software problem.
Try resetting the SMC see link: http://support.apple.com/kb/HT1411
also try re-set the PRAM see link: http://support.apple.com/kb/HT1379
However if you do not have any power at all it probably is a hardware problem.
Is it still under warranty?
Regards,
Andrew

IMAC won't recognize external hard drive anymore

I am running snow leopard on my IMAC with all the latest software updates. I've been using a LaCie Quadra external hard drive with time machine for backups for awhile with no problems. From the beginning is was plug in the hard drive and go, the mac recognized it. Now, suddenly, it won't. When I turn on the LaCie to back up, the icon no longer pops on the desktop. It is also not listed in the Time Machine preferences anymore. I tried to open the LaCie from Mac systems preferences and get a message with something like "64 bit cannot recognize 32 bit" I am asked to close and reopen system preferences, which would change to 32 bit. I tried that and it did not work,and a report was sent to Apple. Has anyone else been experiencing this? Thanks

Thanks. I don't disconnect the drive, only turn it off with it's own power switch. According to LaCie, this should not be a problem.
No, it's not a problem for the drive, but neither is leaving it (and Time Machine) on. Most externals will "spin down" after a few minutes of activity, but even if they don't, modern drives are built to run 24/7.
Time Machine was designed to do quick hourly backups of changes, and will protect you best that way. Just leave both Time Machine and the drive on; they'll be fine.

I tried re insatlling blackberry link, but it still wont work. I really need to trasnfer all contacts form my mac adress book to my new phone. HELP PLEASE!

Go into Settings > Storage and Access and make sure USB Connection is set to "Connect to Mac."
The default is Connect to Windows. Autodetect seems worthless to Mac users too.
