Macbook pro HELP! not recognizing external Hdd and freezing

Hey guys, i need to know why my toshiba external drive works at times and shows up on my desktop and sometimes the external hard drive lights up but is undiscoverable and doesnt show on the desktop? I have also recently noticed that when i plug items into the usb port, the trackpad freezes up. Can you please tell me why it freezes? My macbook pro is only 6 months old is it supposed to be doing this?

I'm not sure why your external drive will not mount, but your computer defintely should not have a 'frozen' trackpad when you plug in USB devices. Since your machine is relatively new, take it in to your nearest Apple Store or an AASP and have them run diagnostics on it.
What you describe is not normal behavior.
Good luck,
Clinton

My MacBook Pro is not recognizing my external hard drive. The hard drive is listed in disk utilities but an icon does not pop up and I cannot access the data. Is there any way to resolve this?

WE know Disk Warrior is more reliable, hence more useful, and should be in any disk mechanics toolchest.
For the record, I don't know anything of the kind. I have yet to see evidence that Disk Warrior is useful at all.
What I do know is that you seem to take every opportunity you get to promote it in these forums. Do you work for Alsoft?
Let me be a little more explicit. My opinion is that Disk Warrior is a waste of money if one has backups. If a journaled HFS directory is so badly corrupted that it can't be repaired by Disk Utility, then the volume should be reformatted and restored from backup, which has the same effect as running DW, but is probably faster and doesn't cost $99.

My Macbook pro will not recognize external devices

My MacBook Pro will not recongize external devices such as hard drives

I know that is of no help, but I have the same problem with a Toshiba harddrive. My wifes Macbook Air recognizes it. No problem with the hd I guess. But my macbook pro won't show it in the Finder, About this mac or disk utility - even though it is running. I would also be glad to get a solution to this.

MacBook Pro does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone?

My MacBook Pro (newest model in 2013 so far) does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone else who has this issue? I returned my multiple HDMI adapters after figuring out it had to be an Apple issue n not the adapters so I can't check it myself now.
Thanks!

I have late 2012 MBP 13" and connect to my Panasonic Plasma correctly.
But using the same cable, can't connect to an LG 47LM6200, the MBP detects the TV, the screen blinks blue, but the TV shows "no sinal detected" message.

You may wish to read about maintenance and upkeep of the OS X, plus other
information, across several topics in this site with topics divided into Guides:
•Tech Guides - TheSafeMac:
http://www.thesafemac.com/tech-guides/
Sometimes, items may have been inadvertently downloaded by accident or due
to poor advisement, and of those some can be a cause of slowness in Mac OS X.
Also, the use of scanning antivirus software can be a cause of slow and disruptive
system issues; since antivirus for the most part is not effective due to the nature of
the Mac OS X and the inability of an AV application to have records of unknown, &
unsubstantiated or rumored issues in the wild, since few or none are known to exist.
The note in the etrecheck report of excessive Page Outs, implies directly that the
computer may need to have more RAM installed; a matching pair of higher capacity
correct spec RAM chips, could be purchased from a reputable source & installed.
As much as, perhaps 16GB in a RAM upgrade, depending on the MacBook build.
All of those red-lettered items in the report that did not load, appear to be system
parts; perhaps that may be something to investigate. Not sure why that is...
{Because today is part of a weekend, I'd suspect the time of day and weekday are
both behind the lack of an earlier reply to your post here. Also, if there have been
weather or other disruptions in the lives of those volunteers who offer help, then
maybe they've had to modify their plans around such events. Or power outages.
We had one here for more than an hour, and everything went out. Even phones.}
So hopefully some other knowledgable readers may contribute ideas on how to
resolve the issues; troubleshooting may be helpful, and to read through sections
of TheSafeMac to see if there is any malware, adware, or other odd activity that
may point to a cause; removal suggestions for those are in that site. Also, if you
had visited any torrent or sharing sites, or downloaded free yet contaminated items
from software download sites, they could also affect your computer. There are
a few areas in that web site worth reading through.
In any event...
Good luck & happy computing!

MacBook Pro will not recognize internal hdd

my macbook pro MB991LL/A 13" 2.53 ghz will not recognize the internal hdd, but when external boot drive is connected it will boot. ive tried two diff internal hdd and the same problem with both of them. i want to upgrade to an internal ssd but im not sure that its the drivee. any ideas on what the problem could be?

My hard drive is now connected. But Time Machine will not let me select the hard drive as my back up drive. This hard drive was used on another Macbook, so Time Machine doesn't seem to recognize the hard drive on the new one. Do I need to reformat the hard drive? I hate to do that because I have the previous backups on there.

MacBook Pro will not detect external speakers, even though it did yesterday

I have a MacBook Pro and it is connected to my HDTV via an HDMI cable and adapter. Yesterday my laptop was able to detect the external speakers in the TV and sound was coming out of my tv from my mac. But today my mac isn't detecting the external speakers and no sound is coming out of my tv. I've tried turning things on and off in multiple ways. Unplugging and replugging the HDMI cable/ adapter. Both of the cables are plugged in properly. Whenever I go to System Preferences>Sound>Output my external speakers aren't showing up. This is so annoying, help me please! Thanks.

I had this problem, too for my 2014 MBP. The output speakers did not show up when I tried to connect through the HDMI port. However, the output speakers did show up when I used an HDMI to Thunderbolt cable.

Macbook Pro (Retina) not recognizing USB devices?

I'm having some odd troubles with my Macbook Pro that I haven't had before.
I have an iLok that's not being recognized by the computer so I can't start up Pro Tools; however, when I tested the iLok on my sister's Macbook Air, it was recognized fine on iLok.com's tests (that also proved not to work with my Macbook).
I also have an Anker 4 port USB hub (not external-powered) that was running my Intellimouse by Microsoft perfectly fine until I shut down my computer last night and turned it on this morning to try it out.
Strangely, the mouse works directly on the USB port, but won't when attached to the hub anymore. The hub worked with another device but my ILok doesn't get recognized on my Macbook through it either (or any of the 2 ports directly either).
I tried an SMC reset (ctrl+shift+opn+power) and a PRAM reset (cmd+opn+P+R on power-on), but everything is still haywire.
I might have installed some updates last night, I can't exactly remember but vaguely can recollect a dialog box from the App Store.
What can I do to really resolve this issue? Is anybody else having something of this sort happening?

Just wondering if you ever found a solution. My mbp retina is not finding my iLok 1. No green light. Max 5 won't authorize.

MacBook Pro won't read external HDD

Hi all,
I have an early 2011 MacBook Pro running OS X 10.9.5 (13F34). I have been using a Seagate 2.0 external USB HDD for movies etc, but all of a sudden about a month ago my Mac just stopped reading the Seagate HDD. I cannot access anything on the HDD through the Mac. It reads the HDD in Disk Utility, but if I try and erase/reformat etc I get the same error message repeatedly (Unable to write to the last block of the device).
Can ANYONE help me with this? Please!
Thanks in advance!
Daniel.

Attach the HDD to the MBP and open Disk Utility.
Click on the Seagate HDD name and volume, each time clicking on the Information icon. See this example:
Please post the following two images:
Ciao.

IPhone with new MacBook Pro - phone not recognized by iTunes

So, I got a new MacBook Pro and connected my iPhone to sync it with iTunes. But the iPhone isn't being recognized.
Anyone know what steps to take to get it to recognize the phone to sync? There are no error messages. Just a phone that doesn't seem to want to sync.
I checked the phone by plugging it into another lap top, and it gets recognized right away, so I'm thinking it's related to the latest iTunes or the MacBook Pro.
Thanks!

Went to the Genius Bar, The tech decised it was a bad logic board. I got a new computer to replace a week old one. After going through setting it up again, I have the same issue. System Profiler sees that an iPhone is connected, but not iTunes. I can not sync to the new MBP. At the moment, I am syncing to my old MBP, just so I have the iPhone set up as I had it.
BTW, if you go through the "iTunes does not see iPhone" suggestions and enter DFU (restore mode) your iPhone gets bricked. But it is recoverable by using a different computer. I am currently trying a NEW install of the OS on the i7, but I suspect a hardware/driver interaction problem. I have no hopes until 10.6.4 arrives in a month or so.

Macbook pro is not getting turn on and further when i press power button the green orange light suddenly changes to green again, moreover battery meter is not working

Hi
Last night my macbook pro gets off automatically when battery gets empty and in the morning it isn't turning on. When i connect the charger, the light on the charger turns green to orange (showing that it is charging) but when i press the power button it suddenly changes to green again. I thought there must not be any connection between the charger light and the power button. And battery meter was running fine.
When it tried this again and again the charger light disappear and battery meter also stops working, when i clearly observe it there is a very dim green light in the charger (not observable in the light) and the laptop is still not showing any change.
please help!

Late 2008 15 inch Macbook Pro will not detect external projector

I have a Toshiba projector that I am trying to hook up to my Macbook Pro for a presentation tomorrow. The computer will not detect the display. I'm using a DVI cable connected to the Mini Display Port. I know I've got the projector on the right input as my white Macbook with mini DVI will detect it but not display it properly (all green).
I've tried shutting down and disconnecting and everything. I need this to work asap.

Have you checked the screensaver and power settings, sleep display etc in the System Preferences?
You can throw this mega cocktail at it, see if it cleans up your problem.
Download the free OnyX here
http://www.titanium.free.fr/
Run ALL the maintainence and cleaning aspects, , especially the caches, you can cancel the reboot in between.
Finially run the Verify > Preference file check/repair and then reboot.
This should clean out all your caches and whatnot.
Then look at this support article about resetting the SMC/PRAM

HT4628 I did the security update on 4-2-13 and now my airport card will not turn on. OS 10.6.8 Intel imac 4,1 core duo. My macbook pro did not have this issue and wifi here is working on that. Is there a setting that was changed? Thank you!

Airport card will not turn on after security update yesterday. worked normally (for the download of the update) until then. Wifi here works fine with my Macbook Pro right now so the issue is with the card / computer / software not the provider. Did the update change something?
OS 10.6.8 imac core duo. The indicator is on the tool bar but is empty.
