My Macbook Pro mid 2012 is not reading/connecting to my (working)external hard disk(also not showing in disk utility)

I connected my 500GB Storjet external hard drive to my mac(Mountain Lion) http://in.transcend-info.com/products/Catlist.asp?modno=325 but it is not connecting to it. Disk Utility is also not showing it. and the hard disk is working... My PS3, My Sony TV and my other laptop(win7) is detecting it... Also whenever it gets connected a blue light blinks, but It doesnt for mac. I have tried reformatting to both FAT32 and NTFS... Please help..
Also I sorta screwed my Mac so I had to do the internet recovery thing and only after that such problems occured, it was working fine before. So it installed Lion first and then Mountain Lion. It wasn't working on any of the OS.

Power down the Mac, Full power off. Connect the drive using the Y cable and then turn the Mac back on.
If it still doesn't show in at least Disk Utility then start checking your USB ports to see if both are working properly. Just plug in a USB thumb drive and that should show in both Finder and Disk Utility. If one of the ports isn't seeing the thumb drive then that port is bad and the system needs to be services by Apple.

Macbook pro (mid 2012) unable to read DVDs

I inserted DVDs into my Macbook pro but it's unable to load showing the following message:
Then I tried using VLC but still had no luck. The bug report was shown as follows:
I'm not sure if it's a problem of area code or something. My Macbook pro is set to the spanish language and it's being used in the UK (automatically detected). The DVDs were bought in the UK. Is there any setting I have to add or change? Thanks for your help!

I have this same problem. My Macbook Pro, completely new (2012), set to spanish language, and being used in Mexico. I inserted a couple of dvds yesterday and none of them were read. I also tried DVD player and got the same message, and then VLC, same thing as above. I tried quicktime as well and nothing happened.
DVDs are original, so I don't get why I'm getting this problem.
Is there a software problem? or is it the drive? How can I solve this?
Help appreciated!

Macbook pro mid-2012 13" has very slow disk access

Until 3 days ago my macbook pro mid-2012 13" running OX 10.8.3 was running fine. Then, it showed very slow response anytime it had to access the hard disk. After doing the usual checks and disk first aid repairs to no avail, I booted from my external disk with an older copy of my hard disk and everything then worked as normal, except when I accessed the internal hard disk, then it crawled once again (spinning beach ball, took many seconds just to open a finder window and then several minutes to display the contents). I ran the Apple Hardware Tests and it said everything was fine, even though it tooks several minutes before the test would actually start. I also ran the program BlackMagic Speed Disk to find out if the disk was having transfer speed problems and it showed a respectible transfer rate (60MB/s), not great but not like the 0.3MB/s I was getting when I tried to back up the internal disk. I was using Carbon Copy Cloner to try to back up the internal disk but had to give up since at 0.3MB/s, it would take days to back up the 250GB on the disk. I found on the web that using "restore" in Disk Utility, I could do a disk copy without the file by file copy which allowed me to back up my disk in "only" 6 hours. Booting from my newly made copy on an external disk worked fine and ran at nearly normal speed (slightly slower since it was an external disk running through USB2). As a final attempt to prove this was a disk problem, I erased the internal disk and reinstalled OSX 10.8. I am still waiting for this install to finish, it has been 5 hours although the progress bar said it should be done in 20 minutes. This was fairly convincing evidence that it is not a software or settings problem. However, all my web searches could find no other case of a problem like mine. I presume I have a failed hard disk but as all the diagnostic programs say it is working fine, I was hesitating to bring it in without hard diagnostic evidence. If anyone knows what might be the problem, it would be much appreciated to hear from you.

It should not take 5 hours to install Mac OS X. There is something wrong with the disk. Try reformatting where you do a wipe of the drive (an select the option to write zeros which will remap bad sectors). Then try to install MAc OS X.
I got this information from here:
http://reviews.cnet.com/8301-13727_7-20064489-263.html
Back up your data.
Use Time Machine or a system cloning utility to create a full and restorable backup of your data. If you suspect bad blocks, then when cloning you might consider not using a "block-level" copy process, since this will likely run into problems.
Boot to the utilities DVD.
If you have a boot DVD for a tool like Drive Genius or another drive utility, then boot to that; if not, use your OS X installation DVD (once you select your language, open Disk Utility from the Utilities menu).
Format the drive.
Using your selected utility, format the drive and check for bad blocks. If you are using Disk Utility, click the Erase tab, click the Options button, and then select the option to write zeros to the disk (you do not need to do multipass erase options, as this will provide no additional benefit for managing bad blocks). Writing to zeros may take a couple of hours depending on the size of the drive, but when done the drive will have remapped any blocks that were not reliably read.
Restore the OS installation.
If you have used Time Machine to create your backup, boot to your OS X installation DVD (if you are not using Disk Utility) and use the option in the Utilities menu to restore from backup. Attach your Time Machine drive and then proceed with the restoration, selecting the newest backup as the one to restore to your system. If you have used a system cloning tool, then attach the cloned drive and boot off of it (hold the Option key at start-up to select it from the boot menu). When you are booted to the cloned drive, run your cloning utility to copy the installation back to the computer's main boot drive.An optional approach here is to perform a full reinstallation of the OS from your installation DVD, and then migrate your data, applications, and settings from either the clone or the Time Machine backups using Apple's Migration Assistant.

The update "MacBook Pro (Mid 2012) Software Update 1.0" can't be applied

When trying to update my new Macbook Pro with Retina through Apple's software update application, I get the error:
The update "MacBook Pro (Mid 2012) Software Update 1.0" can't be applied
The update could not be expanded, and may have been corrupted during downloading.
I've already went through the process twice to download this update.

Same type of error, but getting 90% downloaded and error message that the update cannot be saved. But it then goes to the screen to apply, but with 90% only - no instructions that it will only download 90% and the rest will come during the update - not going to apply.

My non retina macbook pro mid 2012 will read the display its connected to but does not display anything at all

Hi there,
I have a macbook pro mid 2012 non retina display and i tried using an external display for it. I hooked it up and the screen blacked out and turned back on like normal and the computer itself was reading that the display was there. The only problem is that on the display itself there is no image of the macbook being displayed. im using a thunderbolt to vga connector and all the connection check out the only problem is the display. the display works on my other macbook that i have just fine i dont understand why it wouldnt work on this new one. Keep in mind i have had this computer for only 5 days.
Thanks in Advance

My iPad 3 is not charging on my macbook pro mid-2012. It was working yesterday and it is not working now, and I'm trying to transfer files between them. How do I charge my iPad with my macbook without having to be a completely new computer?

I am trying to transfer files between my ipad 3 and my macbook pro mid-2012 and they will just not connect. I connected them yesterday and it worked fine. And i can not air drop these files into my ipad it has to be done through itunes. And i can not afford to buy a new computer. How do i get these two to connect without having to buy a completely new computer?

Computer USB ports, regardless of the computer maker, have a relatively low power output and thus are not good chargers. They will charge but it takes a long time. You should be charging your iPad from wall power, or a more powerful source like an in-car charger.
Buying another computer will not change that.

MacBook Pro Mid 2012 not starting up after Yosemite Update

I'm using a MacBook Pro mid 2012 model , enrolled into Yosemite Public Beta Program ...
After the official public launch , app store suggested that i rather update from beta 5 to beta 6 , as downloading extra 5 gig of OS data seemed unnecessary for me , I just updated from the app store.
Post the update , after shutting down my MacBook , I tried starting it up after 8 hours , it failed to respond to any of my prompts .
Keyboard not responding
Power Button not responding
Li-Po Battery indicator alone works ,
When plugged MagSafe , it indicates charging .
The Sleep Indicator (in the front - that of hard disk drive ) blinks occasionally.
Later, when i tried powering up with MagSafe , It booted luckily , after some 20 hours of work , i shut the system down ,
Again when i tried booting up , it failed .
The problem persists since 3 days.
I tried booting up in Safe Mode - No result
Tried Verbose Booting up - No result
Cleared NV RAM - No result
Cleared SMC as Apple instructed for Intel Based MacBooks - No result.
Removed Battery and kept aside for a while , After an hour tried powering up , It booted up , Went till Apple Logo , The loading bar was some 45%
Then it started to go down with a black screen ,
It never starts up again.
After regular intervals of removing and installing battery , it starts up to white screen and goes off.
I am really worried and desperate now.
I am not sure whether my HDD is dead or my Battery is dead or my Logic board is dead or my Yosemite Install was not right ?
After hours of online research , nothing seems to be helpful .
People at Apple Care (Premium ReSeller , India) are so irresponsible in attending the issue ,
They say its helpless without even doing some basic troubleshoot.
Where would it have went wrong and What am i supposed to do now ?
PLEASE HELP !!

darkrider92,
I have the same model MacBook Pro as the one that you got from your mom. Were you able to install the 10.6.8 update successfully onto the factory drive? Were you using the factory RAM when you tried to install the 10.6.8 update on the SSD?
Have you checked the Web site of the SSD’s manufacturer, to see if there’s a firmware update available for the SSD?
You can download the 10.6.8 update outside of Software Update from Apple here; in case you need to try to install this update several times, running it from your local disk would be more convenient than waiting for it to download again.

HT204384 SD Card will not mount on Macbook Pro Mid 2012 (non-retina), tried everything

I am trying to use a PNY 4GB SD Card on my Macbook Pro Mid-2012 (non-retina), but I cannot get it to mount or for the Macbook to even see it's there. I read some people had success slightly pulling it out, pushing it in faster, cleaning the port, etc. which I have tried all of these, but to no avail.
Anybody have an idea?
Thanks,
-Justin B.

Had problems reading SD cards after a Mountain Lion update. Try this XQuartz solution that fixed this for me. I'm using a 13" MBP mid-2012. All you have to do is install this programme and re-insert your SD card.
XQuartz no longer comes with new Macbooks, only X11.
See this support page from Apple on where you can download XQuartz.
http://support.apple.com/kb/HT5293?viewlocale=en_US&locale=en_US
You can download Xquartz directly from here:
http://xquartz.macosforge.org/landing/
This should be the most up to date version. If not check for updates once you have downloaded it.
Simply re-insert your SD card and voila!

Macbook pro mid-2012 GPU-panic

Hi, my Macbook Pro mid-2012 has recently started rebooting sporadically. After some investigation I found out that it is caused by GPU Panic which happens EVERY TIME when discrete GPU (NVidia 650M) is enabled and its temperature goes over 64-65 degrees (Celsius, according to iStat).
It seems it started to happen after one of the OS updates.
Did you faced this issue? Is it software or hardware related? Are there any workarounds/fixes?
Now I am using gfxCardStatus to use Integrated GPU only, but it makes not possible using any 3D-games on this laptop.
Thanks,
Nikolay

Are you running any anti-virus or internet security software? Any cleaning, tune-up, "keeper," or optimization apps that did not come preinstalled?
Are you set up to do torrent downloading?
Are you using backup software other than Time Machine, like that which comes bundled with a external hard drive?
Are you using an online backup serviceother than iCloud (Carbonite; MS OneDrive; Google Drive)?
Those can run up the internal temps.

Adata sp900 sdd 128-GB ssd, optibay optical drive to replace superdrive, and 16 GB upgrade for macbook pro mid 2012.

Hello everyone,
Thank you in advanced for all of the support. This is my first post to the communities. I just bought a 2.9 GHz core 17 processor MacBook pro mid 2012 13" with 8 GB of RAM and I am in the process of upgrading it. When I bought the MacBook pro originally, I was told that I would never mac out the performance because I do not do a lot of photo/video editing. This is true, but I am an academic researcher and tend to multitask often, having 20+ safari tabs open, SPSS (a statistical program), full screen mail app, full screen calendar app, and preview, iTunes open all at the same time. I often get slow performance and error messages that state low memory. This is why I am interested in upgrading the laptop. I am getting ready to go to medical school and I want to have a powerful laptop. I also want to future proof because I plan on having a dual boot system to mac OS and windows OS.
Because I know I will be maxing out the performance of the computer, I want to take full advantage of upgrades, especially now because the cost of the components is reasonable at the moment. The following are the proposed upgrades:
1. Upgrade my current 8-GB ram (2x4-GB) with 16-GB ram (2x8-GB). I plan on using crucial RAM.
Crucial 16-GB Ram: http://www.amazon.com/dp/B008LTBJFW/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&coli d=2B1KHELSPJPNN&coliid=IYGJWGQDH8LV0&psc=1
2. Replace my optical drive with a hard drive. I will place a SSD into my current hard drive position and then install my current HDD into the optical drive bay with the optibay optical drive caddy. I am doing this because I plan to use the SSD as the boot drive and my current HDD as my backup and files drive. I am putting the SDD into the HDD because I have read it is better to place it in this bay for performance. I will put the other HDD in the optical drive because the performance of that one will not be as important.
Adata SSD: http://www.amazon.com/dp/B008LTBJFW/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&coli d=2B1KHELSPJPNN&coliid=IYGJWGQDH8LV0&psc=1
Optibay Optical Drive Caddy: http://www.amazon.com/dp/B0058AH2US/ref=wl_it_dp_o_pd_nS_ttl?_encoding=UTF8&coli d=2B1KHELSPJPNN&coliid=I3GI8MGWAKXY79
My questions:
1. Is the listed RAM appropriate and sufficient for my MacBook pro?
2. Is the listed SSD appropriate and sufficient for my MacBook pro?
3. Is the listed Optical Drive Caddy appropriate and sufficient for my MacBook pro?
4. Is there still a firmware problem that does not allow for SATA 3 (6Gb/s) support in the optical drive?
5. Would it be easier to format the new SSD outside of the MacBook using a SATA to USB adapter?
6. Does working on any of the listed components void my AppleCare (I plan on keeping all of the original components so I can replace them, if I ever need to see apple support)?
7. What is the best way to put Mavericks onto the SSD to make this my boot drive?
8. What is the best way to make all of my files remain on the HDD, but link to the SSD with the operating system?
9. Has anyone ever successfully upgraded to 16-GB RAM and used their optical drive for a secondary hard drive?
10. Is there any miscellaneous advice for this project?
Please feel free to give partial answers. I know this was a lot of information, but I wanted to be efficient in my post. I am very appreciative of everyone who will contribute.
Thank you!

Macbook Pro mid 2012 15" (non-retina) graphics tearing

Hello everyone,
I would like to post my experiences using two identical macbook pros 2012 (non-retina, with nVidia GT650M 512MB) who presented the same graphics cards glitches and problems, and hopefully to obtain some information.
Exhibit 1: My own macbook pro
Bought from France, in November 2012. Used mainly for professional non-graphics programming, it's clean, no bloated software, and only necessary professional tools are installed. 16Gbytes of memory, by Crucial.
At some point during July, when the machine was relatively cold and I was watching a youtube video, this happened (see attached pics). The mouse was moving, and the computer was fully operational, but with this "glitchy graphics overlay". I logged out, and logged back in. Problem disappeared and appeared again at random times, 4 times during an hour. All those times, a log-out and log-in would fix the problem. After that, I could not reproduce it. Apple changed the motherboard, claiming that it could be a faulty nVidia card.
Exhibit 2: My brother's macbook pro
Bought from Greece, in february 2013. Same model as my own, same RAM, same specs. Used for professional video editing, no bloated software, mostly using Final Cut Pro X. He noticed various malfunctions with FCPX, like freezing when applying a visual effect, and graphics tearing when rendering (that's when the nVidia card kicks in, normally). Yesterday, same symptoms as my macbook pro appeared, graphics tearing, etc.
EDIT: videos of the problem:
http://www.youtube.com/watch?v=jGBijGMO9NE
http://www.youtube.com/watch?v=jnEXtVWgKKM
Both machines are in a completely different environment (I live in France, my brother in Greece), non-smoking areas, and have worked in completely different ways. Both with OS X 10.8.4.
That's two out of two. Given nVidia's background, I am starting to feel that my purchase is not so reliable as I originally thought, and I am thinking that this problem is more generic than originally seemed.
Does anyone have any relevant information on this matter? Could these problems be related to issues with nVidia drivers? Is there any information about unreliable nVidia graphics cards on 15 inch macbook pros mid-2012 (non-retina)?

Hi there,
I would recommend taking a look at the troubleshooting steps found in the article below.

Macbook Pro Mid 2012 Firmware Downgrade

Friends Macbook Pro Mid 2012 model evo to my computer upgraded with 840 samsung 6 months ago, and I was using it without any trouble. But in the last one month I got on my computer machine kernel cache error. With the installation and opening of the original disc, but SSDs doing was making trouble. I gave the service SSD y not change no matter what problems they have learned and change. Carbon Copy Cloner now and again with mac dupper supper time machine backup or recovery took my board if I did not open and the kernel fails again on cahce. Trim off mode, albeit not have them, even if I've tried everything. In the end, many SSDs ef firmware samsung site about a problem with the data transfer rate is found. Now I guess my goal to downgrade version 1.6 of EFI y How can I do my job, you'll see that information transaxle. Downstairs you can see information about my computer.

It may have nothing to do with the firmware of your machine. What is the Kernel cache error? Bootcamp is one option to upgrade firmware of the SSD.
The Samsung SSDs come with Magician, which should allow you test the performance and integrity of the SSD. If it is a HW issue, you should be able to get a replacement. Samsung originally had offered a 5-year warranty on the 840 Pro SSDs.
The other option is a down-loadable .iso from Samsung Support website.

What are the specifications for Internal Hardisk 500GB Macbook Pro (Mid-2012)?

I need to purchase a new internal hard disk for my Macbook, I'm gonna go for 500GB space.
Now. I need to know the specifications. I don't want suggestions, because I live in India and I may not be able to purchase the harddisk which you tell me to.

Will any of the above two harddisk work with my 13 inch Macbook Pro (Mid 2012) model?

Drive #2 would be your best bet - except for the fact that it's a 3.5 inch drive and you need a 2.5" x 9.5mm drive.
Look on your site for HGST 7k1000 drives - 1TB and it will 'fit' your machine exceptionally well.

What are the things required to upgrade internal hard drive For Macbook Pro mid 2012 13 inch?

Hi,
I want to upgrade my internal drive but I don't know how to do that. I have already purchased a WD 1TB internal hard drive. However, I contacted apple support and they said if I try to upgrade the hdd myself, then the warranty of the macbook would be void. I am from India . I currently have a Macbook Pro mid 2012,13 inch.
Also, do i need to download a setup of Yosemite before changing the hdd?
Please guide me
Thanks and Regards
Abhineet Arora

You know what the impact will be on the warranty terms. If you want to install it yourself, look at this video:
http://eshop.macsales.com/installvideos/macbookpro_13_unibody_mid12_hd/
It is not very difficult. You will need a #00 Phillips and a #6 Torx drivers.
Ciao.
